I use these batteries in my five AT&T cordless phones. They have a lifespan of 5 years or more. The old batteries that were replaced were 6 years old and only one in five had started to degrade. The rest still worked perfectly. They are so cheap that I changed all the batteries at once.

Bought these batteries to replace the ones in my home phones. The original batteries got to the point where they stopped holding a charge and calls dropped for a minute or two during a call. Pull out the old ones, put them in, let them load and voila - like new. I don't know how long they will last as I only bought them last month but they work great and hold a charge.

I ordered these batteries to replace the original batteries that came with phones for AT&T BT8001. They arrived quickly and work with phones meaning I don't have to buy a new system! I changed batteries one at a time and let them charge before moving on to the second, third, etc so I wouldn't blow up the whole set if they didn't work. They work!
