VERY fast shipping! when I put in the new battery it was at 42% charge but it wasn't charging up. I saw this solution on other websites. So I followed these steps: Shut down the laptop. Remove battery and AC adapter from laptop. Press and hold power button for 1 minute. Plug AC adapter without the battery. turn on the Computer. Goto Control Panel, then Device Manager, expand battery entry, right click, uninstall ACP /compliant control method battery. Wait a few minutes, shut down the laptop. unplug AC adapter and put the battery back in. Start the laptop. Wait a few minutes. Shut down the laptop again. plug AC adapter with the battery still in the laptop. Start the laptop. This may help some people.

Spare 807957-001 807956-001 807612-421 HSTNN-LB6U HSTNN-LB6V HS04 HS03 Laptop Battery for HP Pavilion 15-ac130ds 15-af087nw 15-af093ng, HP 240 G4/ 245 G4/ 250 G4/ 255 G4/ 256 G4, 14.8V 2600MAH Review:

I have an HP laptop, needed a battery, HP part # 807957-001. Could not find it at Staples, where I have bought it before. After reading up on the HP site, I saved over $45 by getting this one on Amazon. It's the same battery, listed my part number. I was skeptical, but after 10 days, it holds a charge well. I'm glad there are these substituted on the market. Just check for your part number through your laptop manufacturer.

Sony CR2025 Lithium Battery (10 Pack) Review:

Works with TILE Mate model T3001. Sony CR2025 3V worked as a replacement after the original Maxell battery ran out (about 6 months use on my primary set of keys). The batteries were shipped in a timely manner. They arrived in original Sony packaging with a "Use By 2026" date. The Tile is not easy to open but there are YouTube videos that show how. You don't need to cut it open but can carefully pry it open. I used a paring knife to start (while wearing a cut resistant glove) and then a butter knife to wedge the two halves apart. Always point a knife edge AWAY from you! Battery removal has a second obstacle because Tile puts a dab of super sticky adhesive on the original battery. But once you swap the battery and snap the Tile case back together, it will work fine. The affordable price point for a 10 pack of Sony batteries means that I have extras for future Tile replacements. Good buy.

DTK New Laptop Battery for Dell Inspiron 3420 3520 N5110 N5010 N4110 N4010 N5040 N5050 N7110 N3010 M5110 M4110 M501 M503, Fits P/n J1knd 4t7jn [6-Cell 5200mah/49wh] Review:

I have a Dell Inspiron 3520. I got it as a hand-me-down some years ago (early-to-mid 2015), and use it as my daily driver. This thing is great. I have upgraded it with a 500GB SSD (from a 320GB, horribly slow mechanical drive), and additional 4GB RAM stick for a total of 8GB, and a third-gen Intel Core i5 2.7GHz with Intel HD 4000 graphics (up from the included dual-core, 2nd-gen Celeron 1.7GHZ with Intel HD "unnumbered" graphics). The laptop is virtually bulletproof, which is great since I'm on a robotics team (i have a small scratch in my screen from an arm on the robot :).

I ordered this battery on June 14, 2017, according to Amazon. The battery I had at the time would die in a matter of minutes if my CPU kicked up to full, and since I have a script that automatically downloads and re-compiles SuperTuxKart when a new commit has been made to the repo, this would happen quite often, resulting in my running (often literally) to plug into a power cord.

The new battery solved this issue, and gave me much more battery life. Having a good battery felt so great. I could often use my computer for a whole robotics meeting without plugging in! It worked great until about 1-2 months ago, when I had my computer randomly lose power. The battery still showed a good percent, but it suddenly went from being on to not, not even sleeping or shutting down. This happened a couple more times, same situation with the percent being good, but just instantly loosing power. I suspect the cells are still good, but the circuitry can no longer keep power supplied when the power draw increases.

All in all, if you have one of the Dall laptops that uses this type of battery, and you need a new battery, I definitely recommend this, but be ready to replace it once it gets unreliable. Considering the issue is most likely a circuitry issue, hopefully my next one will last longer before needing replacement, but who knows. The reality is, as far as batteries go, this is probably about as good as you can get, especially since OEM batteries, if you can even find them, have probably been sitting on a shelf degrading for 5 years.

Maybe some time I'll try cracking open the battery and replacing the circuit board with one from an old OEM battery that is reliable but has horrible battery life and see if I can get some more life out of it...

Seems to hold a charge but only time will tell. There is no drainage while not connected to power. I have only cycled through power 4 times as seen by the diag below. I'm happy so far for continuing to use my Mid-2012 13" Macbook Air.

A1322 New Laptop Battery Compatible with MacBook Pro 13'' A1322 A1278 (Mid 2009, Mid 2010, Early 2011, Late 2011, Mid 2012) Series, fit MB990LL/A MB991LL/A MC375LL/A MD314LL/A MC724LL/A Review:

I was thinking about having to replace my 2009 MacBook Pro because it wouldn't turn on and Apple no longer replaces batteries for this model because it's so old (trust me, I'm not complaining). But I decided to try one last thing before I made that plunge. I found a link with instructions to replace my battery and bought this battery that came with the necessary tools. It was pretty straight forward. My computer had not worked for at least 6 months prior but I used a work computer so I wasn't bothered until that was no longer an option. Well over a month after replacing it, it still works perfectly, charges well, and lasts as long as my original battery did when I got it. I would definitely recommend if you're in the same position (suspect your battery is officially dead and not yet willing or don't have the funds to replace the laptop). It saved me a lot of money until I actually have to replace it one day.

Notebook Battery HS04 HS03 for HP 240 245 246 250 256 G4, HP Notebook 14 15, HP 807956-001 807957-001 807612-421 HSTNN-LB6U HSTNN-LB6V N2L85AA 807611-421 807611-131 HS04041-CL (AC Doctor INC) Review:

I bought my laptop 4 years ago. It was the first large purchase I had ever made after opening my bank account starting college and getting a real job. It was my first real adult purchase and I’ve used this laptop for EVERYTHING. Growing up I was notorious for breaking my laptops, getting virus’ and you know just doing anything in my power to destroy my things, but I was super careful with my laptop.

Then the battery died on me. It came out of nowhere right before the semester started up again, but I was super lucky to find this battery. I did not want to buy a whole new laptop after i worked so hard to take care of it. This replacement piece saved my life and my battery. Now I don’t have to leave my laptop on the cord when i use it. It back to being like brand new. It has a great life span and was super easy to pop into place.

It’s been a year since I bought it, and my laptop is better than ever.

Replacement Battery for HP Spare 593553-001, HP Compaq Presario CQ32 CQ42 CQ43, HP Pavilion dm4 g4 g6 g7 DV3-4000 DV5-2000 DV6-3000 DV7-6000, COMPAQ 435 436, fits HP MU06 (General Battery) Review:

I've only had this battery for about two and a half months, and only used it about 3 times - perhaps once successfully. The computer won't turn on with the battery in it, only if I remove the battery. If I get it to turn on, plugged in with no battery, and then add the battery in, it says that it's fully charged and lasts a few hours, but something is wrong with the battery. I either need a refund or a replacement asap.

UPDATE: Even if I turn it on with the battery disconnected, and then add the battery, the battery no longer holds a charge and the laptop dies as soon as it is unplugged. It's entirely useless now.

2nd Update: Was finally able to communicate with the seller, and they immediately responded and sent a replacement battery. Sometimes things break- it is how the seller responds that is as important as the item sold- they responded very well.

SLE 14.8V 40WH M5Y1k Battery for Dell Inspiron 3451 3551 5558 5758 M5Y1K Vostro 3458 3558 Inspiron 14 15 3000 Series Review:

It fits in my Dell laptop and there are no issues with the laptop recognizing it and charging it. Can get around 4-5 hours of battery life.

Giving it 4 star as the markings on the battery are somewhat different from the picture on the product page and it doesn't say cells made in Korea. Instead it just says made in China. Doesn't break the deal for me but still concerned that the lettering is different from the picture.

Also it was difficult to fit the battery in its place in the first place and I was concerned at one point if it will work. Somehow was able get it to fit.

Spare 776622-001 Battery for HP LA04 728460-001 752237-001 15-1272WM - High Performance New Review:

So far the only thing I do not find myself satisfied with is the fit. yes, the laptop is working, yes the battery is charging, yes the charge lasts several hours! however the fit is not flush. I fear the battery will eventually pop out. it does not easily lock in place. one of the two releases does not lock on to it. I put the original back on and there are no problems, swap it with this new one and I have to make an effort to get it to go in and secure it. It is just a minute size or gap issue, I am positive I can have it fitting perfect with the use of emery board, sandpaper or a small file. apart from that no other issues. quick delivery fast charging and good price.
