BT446 BT-446 BBTY0503001 BT-1004 BT-1005 GE-TL26402 BT-504 CPH-488B Rechargeable Cordless Telephone Battery DC 3.6V 800mAh Manufactured by Corun for Uniden

These Corun batteries were the correct/full size, had a fresh date code and seem to be performing as well as the original batteries. So far I'm very pleased with them. I've purchased other batteries that claimed to be genuine Uniden but they were smaller (made with AAA cells rather than 5/4 AAA cells). Those shorter battery packs just didn't work as well as the OEM batteries (they have a much shorter life). Those shorter batteries are very cheap but not worth it. Jan. 2019 Update: I've been using these batteries for 6 months now and they are still performing great. My phones will hold a charge for many days at a time off the charger - just like they did with their original batteries.

It says these are OEM batteries. Maybe, but I do know they last at least two years, which is much better than any other replacement battery I've used. They are reasonably priced. Given that we have five different handsets around the house, I keep some spares as they seem to hold a charge and will accept a charge even after leaving them in a drawer for a year or two. I prefer to use my cell phone, my wife prefers to use the uniden handset with the speaker. Even after two years in the phone, she can talk for at least 2 to 3 hours before she gets a "low battery" warning.

They fit well and work fine in my portable telephones.

I noticed when I installed the battery that the connector was short. The only way to install in our Uniden brand phone was to pull connector across the battery. It is working ok, BUT I have a concern of getting too warm, and shortening the battery life. I do not plan to purchase this brand again for this reason

It was a perfect fit for the handheld phones around my house. They were no longer charging

THESE ARE THE REAL DEAL. They are the correct length, they work beautifully and they hold the charge. You can buy cheaper replacements but in my experience, the shorter than original batteries do not last.

Fresh Batteries! They last during long conversations. The last ones I bought a few years ago from a different vendor didn't hold up well. I was always switching phones because the battery low indicator would starting beeping during the phone call in a very short time. Thus far, I have talked for 45 minutes on a single phone and when done, the battery remaining charge indicator is still at max bars. Hope it lasts.

Buying off-brand batteries online is a matter of odds, in my opinion. I think in applications like cordless phones it's reasonable to take a chance, if you get a good price. I assume that some of these batteries will perform well and some will fail quickly. My plan is to replace the ones that fail quickly and write off the inconvenience as offset by the price. I wrote the install date on the batteries. I'll try to remember to update this review based on the simple criteria of whether or not they perform adequately for a year. On mission-critical applications, I'm much more likely to go with name brand batteries.
