I purchased two batteries because I have two phones. I always switch out the batteries in the phones, but the issue I encountered was that I didn't do it all at once. I'm not sure which phone still need a new battery because I couldn't locate one on the batteries. There are no differences between the numbers on the old and new batteries that I can see!

My 95-year-old mother recently moved into an assisted living facility, and while organizing her home to get it ready to sell, I found an outdated V-Tech cordless phone that she had stashed away. I took a chance and sought for a battery to put in the phone in the hopes that it would still work even though the battery was dead and the phone appeared to be in fairly excellent condition. I stumbled into this one, and it was reasonably priced and listed as a valid replacement for the model number of this phone, so I bought it.Results - This battery matched the original one in the phone exactly in terms of size and rating. Once I inserted it into the phone and docked the cellphone, the charging process began. Since I started using it, everything has been running smoothly. No grievances. Phone fits well inside. correct connection decent pricing. Excellent battery replacement. The package came with two batteries, so I also have a backup in case I need it. I'd definitely place another purchase from this merchant.

Hv had these for only about a month. a replacement for the dead batteries that were in my mother's phone handsets. We'll have to wait and see how long they survive, but for now they're fantastic. They "appear" to be the same ones in her handsets. These cost a tiny fraction of what the nearby battery store demanded for them. WARNING: The packaging is deceptive—but not in a negative way. To be clear, the handset battery pack contains what I shall refer to as "2 batteries." I ordered 3 because I needed batteries for 3 different phones. Each shipment has two battery packs, therefore I actually received six battery packs. I would have ordered 2 packages if I had known how they were packaged at the time; I would also have had 1 extra. (I did speak with Amazon about this.)

New Genuine OEM Uniden BT-1021 BBTG0798001 Cordless Handset Rechargeable Battery (2-Pack) Review:


For YEARS, I've owned a set of four Uniden cordless phones. We had some trouble at the time locating a cordless phone that would last more than a few months to a year without experiencing any sort of problem (I guess things aren't made like they used to). The fact that the Unidens we bought were reasonably priced was a HUGE benefit. And they were fantastic! Through three children and hard wood floors, they were able to stand up. My heart ached as these began to cause us problems. After talking on them for 10 minutes, all 4 phones would suddenly stop working (but remember... This was after YEARS of use). I genuinely didn't want to part with them. I wasn't certain that the failing batteries were the cause. However, I decided to give switching them out a shot before looking into other phones. I purchased two of these, and now my phones function flawlessly once more! They hold the charge (like they are fresh new), were incredibly simple to install, and were also reasonably priced.I should add that I had to get in touch with the seller. Who was AMAZING and really easy to work with... And SO lovely! I wanted to commend them for it.



Panasonic HHR-75AAA/B-6 Ni-MH Rechargeable Battery for Cordless Phones, 700 mAh (Pack of 6) Review:


I have landlines because I live in a rural location where cell service is poor. I own a pack of standard poodles that I rescue, so when the phone rings, I have to vault over the poodles and toys to get to the phone. There is at least one phone in every room, and some rooms have additional phones with bases. Due to the batteries running out of power after around 4 hours, I was missing calls. Replace batteries was the notification on my hand set. Wow! Rechargeable batteries were something I had planned to use, but my phones would not accept them. I'm really delighted Amazon offered these because they were much more affordable than purchasing additional phones. I never had to change the batteries in my phones before, so I was quite appreciative that they operated flawlessly for 12 hours after being charged over night. I make an effort to have them lying around whenever I plan to be there, and at night, I place them back on the stands. Within three days, UPS delivered them. arrived at my door, did its job, and saved me time and money.

Panasonic HHR-75AAA/B-4 Ni-MH Rechargeable Battery for Cordless Phones, 700 mAh (Pack of 4) Review:


Since it is harder over time to locate the precise battery pack and connector required to replace worn-out phone batteries, I won't purchase cordless phones with battery packs. Panasonic offers mobile devices that use common AAA rechargeable batteries. The batteries in some phones have only been changed once in the ten years I've used the same Panasonic cordless phone. Over time, these batteries have proven to be dependable. Before losing charge, they have a long life. They are available in different size packages to suit your needs and are more affordable for larger orders. I'll unquestionably keep buying these batteries as long as they're accessible.
