Best Camera Batteries in 2020

Arlo Batteries - RCR123A Li-ion Rechargeable Battery & Charger [750mAh 3.7V 8pack] for Arlo Wireless Security Cameras (VMC3030/VMK3200/VMS3230/3330/3430/3530) Flashlight Microphone Polaroid  Review:

I have been looking for a rechargeable solution to replace single-use CR123a batteries in my tactical lights and WML's. I was hopeful when I received my eight Rapthor RCR123a 750mha 3.7v rechargeable Li-ion batteries and four channel battery charger.

I do have to admit that when I placed the order I was concerned the high lumen output of my lights would trip the internal protection of the Rapthor batteries. Also, that their 3.7v output could be harmful to my lights which were designed for 3.0v CR123a's. My concerns were unfounded.

So far, these rechargeable batteries have met all of my expectations. I have these installed in an Inforce WMLx (800 lumens), a Streamlight TLR-2 HL G (800 lumens), and a Surefire 6PX Tactical (600 lumens). All are working as expected, and battery life is acceptable for my usage. Knowing that I can alternate them with freshly recharged Rapthors on a weekly basis if I choose to and still have them last for several years is comforting.

I highly recommend these rechargeable batteries to those looking for CR123a replacements outside the ARLO camera environment.

Canon Battery Pack LP-E17 Review:

This battery pack came with my Canon T6i bundle and was sold to me by Amazon.

What else can I say? It definitely works like a charm and have used the product (I believe I've recharged it twice now at the time of writing this review). The only things I would advise buyers of any camera battery is to avoid buying third-party/off-brand batteries and just stick to your camera manufacturer's batteries, although I know they can be pretty expensive. But buying Canon batteries for your Canon camera or Nikon batteries for your Nikon batteries, assures you of complete compatibility and official product warrant. As for the battery itself, this might be just me being OCD, but the white battery cap goes on the battery pack where the arrow is exposed (as seen in the picture). Also make sure that it has the Canon holographic portion on the bottom of the battery pack as I have seen off-brand batteries imitating these battery packs semi-accurately.

Feel free to disagree with any of my opinions, or even link me to credible off-brand batteries because just like you, I'm also a consumer who likes to save :)

Nikon EN-EL15b Rechargeable Li-ion Battery Review:

Although it is possible to use EN-EL15 and EN-EL15a batteries in the new Nikon Z7 and forthcoming Z6 cameras, only the new 15b version is able to be charged while inside the camera. This is done by simply plugging in a 5 volt 3 amp USB C power adapter. The needed EH-7P power adapter is included with the Z7, but also works with similar adapters I have for a current Macbook Pro and a 2015 Google Pixel Chromebook. That allows me to support all three devices with only a single charger when traveling.

The new EN-EL15b battery also has a slightly higher capacity (1900 mAh) than the EN-EL15 and EN-EL15a variants, which is useful with the higher electrical needs of the new Z series cameras. My understanding is that the EN-EL15b can also be used in any camera that fits the EN-EL15 or EN-EL15a.

It takes about 2 hours and 35 minutes to recharge the EN-EL15b when completely discharged, officially giving enough power for 330 shots on a Z7, but based on early tests usually enough for an all-day shooting session. Even so, I feel safer with 2 extra batteries, and love that I can charge 2 at once - one in the camera and one in the MH-25a plug-in charger supplied with the Z7.

Anyone buying a Z series Nikon camera should definitely also buy at least one extra EN-EL15b battery, to be sure of enough power for a long day of shooting.

TalentCell Rechargeable 12V 6000mAh/5V 12000mAh DC Output Lithium Ion Battery Pack for LED Strip and CCTV Camera, Portable Li-ion Battery Bank with Charger, Black (Multi-led Indicator) Review:

Update: 24 Feb 16. I have multiple packs in use (5 packs). The packs are all made of Samsung ICR18650 cells that are rated at 2600 or 2700 mah. In reality they are being advertised at a higher rating than they really are. The 3ah pack is actually a 2700mah pack, the 6 AH pack is actually a 5400 mah pack and the 9 AH pack is actually a 8300mah pack (which easily powers my Celestron CGM DX telescope all night for astrophotography). I see there are multiple questions about charging these packs- you have to use the 12.6 volt AC adapter that comes with it or have another 12.6 volt regulated power supply to keep from over charging them and damaging the battery pack. You can't just plug them into the cigarette lighter of your car.
The display LEDs do a pretty accurate job of displaying the voltage of the pack. All LEDs lit- 12 to 12.6 volts, 3 LEDs lit- 11-11.9 volts, 2 LEdS lit- 10-10.9 volts and 1 LED lit- less than 10 volts and it time to recharge. Do not over discharge the pack as this shortens the life of the cells.
The 5 Volt USB output will fast charge your phone or tablet at up to 2 amps so it's a great field charger for these devices.

Previous review: I have two of these battery packs in use. It Works great to power my Bose Acoustic Wave Radio. It runs my radio all day at work (10.5 hours) at a fairly loud room filling volume and still has 1 green LED left. This pack is way lighter than carrying around a comparable capacity 6AH lead acid battery. I also use it to power my Celestron CPC1100 11inch telescope. It worked great during a recent star party and lasted fine through the 7 hour night time viewing session with two green lights still lit after we were done for the night. I also tested the 5 volt USB output and found that it charges my IPad Air at the full 2 amp fast charge rate and charges my iPhone 6 also at the full fast charge rate. The battery pack and cable weighs 13oz (which is way better than my 8 lb lead acid battery pack). If I should experience anything different I will be sure to update my review.

Update 9/13/18 The battery packs are still going strong with no issues and no problems. They do have over discharge protection which is a nice feature as I have accidentally left devices on and the circuitry has protected the battery pack from being damaged. I still highly recommend them. If your device runs on 11-12 volts and less than 3 amps (for the 6000mAh pack) or less than 6 amps (for the 8300mAh pack) then these will work great for you!

Energizer CR2025 Battery, 3V Lithium Coin Cell 2025 Batteries (2 Battery Count) - Packaging May Vary Review:

Aside from selecting the correct battery in the first place and sticking to brands with a reputation for quality, the most important consideration in buying batteries is freshness. I was hesitant to buy batteries online because you can’t check the expiration date on the package as you can in a brick-and-mortar store, but laziness finally overcame my apprehension. Why waste time driving into town to buy them when they could be delivered to my doorstep? I was therefore happy to see that the Energizer 2025 button batteries I purchased from Amazon on 1/20/2017 have an expiration date of 3/2/2024, a window of just over 7 years.

This particular type of battery (lithium 3-volt coin or button) is used primarily for watches and automotive key fobs. In my case, I bought these because I needed to replace the battery in one of the key fobs for my 2002 Acura TL. I believe that this is only the second time that I've had to replace it, which is a cinch to do. I chose Energizer because I've had good luck with Energizer batteries over the years. I bought some off-brand batteries once and learned my lesson.

I chose a two-pack because I know that the battery in my second key fob will need to be replaced at some point, and I wanted to have a spare on hand when it does. In general, I try to avoid buying batteries (especially specialty batteries like these) too far in advance because all batteries have a shelf life. It's impossible to predict (for me at least) how much longer the battery in my second key fob will last because that I use that key fob only sporadically. When my second key fob battery does go, I’ll be all set – assuming, of course, that I’ll be able to find my spare battery and that my car will still be running by then. Come to think of it, these batteries could very well outlast my car.

Note to other shoppers: I really don't know if the 7-year window before the expiration date on my batteries is typical. YMMV (Your Milage May Vary). However, for anything with a shelf life, it makes sense to buy from a vendor that is likely to have a high turnover (and therefore fresh stock), or one that guarantees its products. I would be interested to hear how other buyers have fared in this regard. Is seven years typical these days?

Artman GoPro Hero 5/6/7 1480mah Replacement Batteries (3-Pack) and 3-Channel LED USB Charger for GoPro Hero 7 Black, Hero 6 Black,Hero 5 Black,Hero 2018(Fully Compatible with Original) Review:

Great delivery speed. This product comes in a very well pack box. The product itself is small and does not take up too much room on my desk. Se pic. My only issue is this. The battery in my GoPro just happened to need to be charged at the same time I got this product. So I decided to do a side by side test of the charging speed. I unpacked this item and set it up. I then plugged in my GoPro to charge and set the 3 batteries in the charging dock. The batteries snapped in to what I thought was a snug fit. When the camera was done charging 2 of the 3 lights on the charging dock remained red while one was green. It had turned green about 1/2 hour before the camera got done charging. I thought this was odd that the two lights remained red so I pressed down on the batteries. Nothing changed. I then pushed them to the side and the lights turned green. Uh oh, loose connection? Anyway, they remained green after a few minutes, so I pulled them. I placed each one in the camera and they all showed that they were 100% charged. So apparently they were charging and maybe the connection to the LED is loose? I dunno, but overall I am pleased with the product and the delivery time frame.

Infant Optics DXR-8 Rechargeable Battery (Infant Optics Official Accessory) (Will NOT Void Warranty) Review:

We've been using our monitor daily (and also for naps on weekends) for over two years. We love it and definitely are glad we chose this model. I've been doing the battery reset thing for a while - maybe even a year - by leaving the battery disconnected for the morning, for example. But that has gotten less and less effective with time, to the point I was having to reset it everyday, and with baby #2 on the way, I decided it was time for a battery update. I got this about a month ago, and it's like a new monitor again. I'm sure with time I'll need to reset this battery as well, since this issue seems to be with the screen unit itself, but if I get another two years out of the monitor for just the price of this battery, it was obviously well worth it.

Arlo Accessory - Rechargeable Battery | Compatible with Pro, Pro 2 | (VMA4400) Review:

I have the Arlo Pro home security/monitoring system. Each of my four Arlo Pro cameras came with a single Arlo rechargeable battery (four batteries total), and the 'kit' came with a single 'wall wart' type battery charger. Here is what would happen: Eventually one of the four camera batteries would become depleted, and the Arlo system would send me a text message and an email advising me that a camera battery was nearly dead, and needed to be charged or replaced. Kudos to Arlo/Netgear that the system allows me to name each camera, and the alerts would say something like, "Basement camera battery is low", or "Living Room camera battery is low". The problem is that I had four cameras and only four batteries; when a given battery would get low, I would have to take the camera down from wherever it was mounted, take it to where the single charger was located, open the waterproof charging hatch on the camera, plug in the charger, wait a few hours, then unplug the camera and mount it again. During the charge period, that camera would not be functional.

With any other rechargeable battery powered equipment I own, whether it is a handheld drill or a digital camera, I usually have one or more spare batteries, and keep at least one battery always plugged into the charger and thus instantly ready for use to keep the equipment operational. I inquired of Arlo/Netgear if they had a similar accessory for the Arlo Pro system, and they pointed me to this "Arlo Pro Charging Station".

This product comes with the charging station itself, plus a single 'wall wart' charger that appears to be identical to the charger that came with the original Arlo camera kit. The wall-wart charger plugs into the center of the charging station, and the rest of the charging station is really just a pair of receptacles into which Arlo batteries may be plugged (or docked). One battery can dock with each end of the charging station. Pressing the battery into its dock, it locks in place, and pressing it again lightly it is released and a spring pushes it out of the dock so you can grab it to pull it out the rest of the way. This is pretty much the way you can press an SD memory card into a digital camera, and press again to extract it.

The top of the charging station has two LEDs, which show the charging status of the two batteries. If only one battery is docked, it charges at the same rate as it would if you just plugged a camera with a depleted battery into the charger that came with the Arlo kit. If you dock two DEPLETED batteries into the charging station at the same time, they charge at about half the rate they would charge individually. You can leave one or two batteries in the charger at all times, topped off and ready to be used in an instant (I verified this with Arlo/Netgear tech support, because the product literature and specifications don't mention this).

It is important to point out that this product does NOT come with batteries, so you need to buy one or two Arlo batteries along with this product if you wish to use it as intended. It does not make a lot of sense to buy it if you do not have at least one spare battery on hand to charge, and keep charged, while each of your Arlo Pro cameras are using the main fleet of batteries that came with the Arlo product in the first place. So please keep the cost of those in mind when deciding if you would benefit from buying this product.

Now, when I get an Arlo alert that a battery in a camera is depleted, I pop one of the two charged batteries out of the charging station, take it to the camera, swap it for the depleted battery and pop the depleted one into the charging station so it will be ready when needed for the next camera. This takes only a minute or two, and sure beats the alternative. But of course such convenience comes at a monetary price.

A few comments. I bought this with two new Arlo batteries, of the same model as the ones that came with my camera. I bought all of this when I got a low battery alert, and because of Amazon Prime I had it all a couple days later, and the low battery still had enough juice to keep the camera operating over that time period. I let both new batteries charge overnight in the charging station, and both indicated FULL on the LEDs. But when I went to swap out one of the two new, fully charged batteries into the camera in question, it was in operative after the battery swap, and the Arlo app indicated that the battery was registering as empty. There followed some experimentation, and eventually I was able to ascertain that one of the two new batteries was defective, even though the charging station indicated that it was full. I used the charging station to recharge the originally depleted battery, which then worked properly with its original camera, and I marked which of the two docks on the charging station I had used to charge that battery. Then I used the Arlo app to determine which of the other three cameras had the next most nearly depleted battery, and charged that battery in the other dock on the charging station, then put it back into service. This proved that both docks of the charging station were in fact capable of fully charging their respective battery. Then I took the apparently defective battery and tried charging it 'in camera' using the single wall-wart charger that originally came with the camera 'kit', and that battery failed when placed back into service. I checked with Arlo tech support, who agreed with my troubleshooting methods and analysis, and asked me to mark the defective battery in a certain way, then return it to Amazon for a replacement; presumably the special marking would be used when Amazon ultimately returned the defective battery to Arlo. I mention all this because A) although the Arlo batteries (and Arlo product in general) seem to be of a high quality, defective batteries are not unheard of, and B) this charging station might indicate that a battery is fully charged even when a faulty battery is not actually charged up fully. These batteries, like many (most?) Lithium Ion batteries, have multiple pins on their electrical charging connectors, because each individual cell in the battery is charged and monitored (as opposed to treating all cells in the battery as a whole). Apparently, one or more cells in that defective battery were either bad, or not connected properly internally, in such a way that the charger though all was well when it was not, at least according the camera.

My second comment is that I rather wish that Arlo had provided some simple means to indicate which of the two battery docks should preferably be used the next time that a charged battery is needed, so the user does not just always use one side of the docks and possibly ignore/neglect the battery in the other dock. It would be human nature to habitually use the same dock all the time, or forget which one had most recently been used. Absent such a feature, I laid a small plastic piece on top of the dock that I want to use the next time a charged battery is needed, and then move that plastic piece to the other dock every time I swap out a battery.

My third comment I think it is advisable to mark each battery in your fleet (in my case, I numbered the four original batteries 1 through 4, and the two newer batteries were marked 5 & 6; I used a black Sharpie pen for this purpose). You could optionally keep a record of battery use, but at least if you start suspecting a problem with a battery or a charger, having the batteries numbered would be useful.

Arlo Certified: Tenergy 3.7V Li-ion Rechargeable Battery for Arlo Security Cameras (VMC3030/VMK3200/VMS3330/3430/3530) 650mAh RCR123A UL UN Certified 4 Pack Review:

I've tried several other rechargable batteries that say they work with the Arlo, but I have to recharge them every week and they fail quickly. I purchased 4 of these to see if they are any better. So far none have failed and after a month I have not had to recharge them once. Bought some more today.
