The the family has an AT&T phone set and two of the batteries are not charging. The assumption that she, I got this battery set to replace the batteries on the phone set And they work perfectly. They charged up very fast and work with all the handsets. very good value for the price.

Worked perfectly.

Reasonably priced, worked great.

Worked fine , initially thought of replacing whole old phone. But replacing battery with this worked and saved me a lot. It did not come with full charge. We need to charge.

These batteries were a perfect fit, were simple to install, and worked perfectly with our AT&T phones.

I purchased the BT183342/BT283342 2.4V 800mAh Ni-MH Battery Pack as a replacement for my Cox cordless phone, and it works perfectly. The installation was simple—just unplugged the old battery and connected this one without any issues. After a full charge, the battery holds power well, providing long talk time and standby life similar to the original. My phone now lasts for days without needing a recharge, and I haven’t experienced any drops in performance. If you’re looking for an affordable and reliable replacement for your Cox or VTech cordless phone, this is a great option. Highly recommend!

These replacement batteries worked well for my cordless phone. Batteries with their little cable had to be placed neatly into the compartment. If not phone cover does not go back in place.

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.
