Great product. Perfit fit. Works great,

I was very pleased to be able to keep my Eufy up and running. For whatever reason, allowing the Eufy to sit on the charger unused for a few months discharges the battery. This is annoying, but I do not know if this is a deficit of the battery or the electronics of the charging device. It is certainly more cost effective than throwing out the Eufy and having to buy another robotic vacuum, but I certainly wish I did not have to replace the battery when Eufy is abandoned for a few months...

Bought these for replacement in some of my AT&T handheld wireless units. Easy to install, life of the battery is good. No change in the quality of the calls, rings, or illumination. No dropped calls. Charge quickly. Would buy again.

Repeat buyer. These have held up well in my cordless phone for a couple of years. Very easy to install.

So far so good. They arrived about half charged. Topped off and they are holding charge as expected. Direct fit for my AT&T phones. They appear to be well manufactured and look just like the originals

I purchased these batteries because I was experiencing a problem with my CL82507 phones, these phone are several years old. Each of the phones periodically show fully charged but do not work, unplugging and re plugging battery will cause phone to show low charge but still do not work. They will recharge and operate normally after charging and may work for extended periods. I am replacing all the batteries in hopes this will correct the problem. AI suggest charging for 16 hours uninterrupted. I will update when I feel the problem fixed. So Far So Good. (Update) The new battery worked normally for about 3 months , but same problem returned, may be time for new phones.

These batteries work great!

I live in a rural area where cell signal is often weak and intermitent so we still have a landline phone system. While we don't use it often, it is good to have when our major wireless carrier lets us down and we revert to last century's communications technology These are a perfect fit in our 20 year old V tech landline phone. We can usually find all 4 of our handsets so I ordered the 4-pack of replacement batteries. Each battery fits perfectly - the connectors latch into place and the batteries fit exactly into the recess so the cover closes securely. The batteries arrived quickly and had about a half charge so I could immediately tell they powered the handsets. I checked each battery for overheating during charging and found none. The charge lasts 2 or 3 days off the charger in standby mode. That is plenty of time to misplace the handset, so having a long life is critical in using the find handset feature on the base station. These batteries are very low cost and keep our landline phone system working like it was 1999 all over again. I can easily recommend these to anyone with compatible phone handsets. They fit. They work. They get 5 stars.

Muy buen producto vale la pena
