Question: How many volts is this battery?
Document: The battery in my cordless phone gave up the ghost after many years of use. This battery appears to be an adequate replacement.
Excellent price for this type of battery, worked as advertised, not many more words available to describe this simple battery
The remote on my  Uniden  phone  &#34; a few years old&#34;  would not hold a charge  I considered dumping a  5.8 GHz  but perfectly usable  phone  I replaced the battery and now will get many more years out of it.
Just what I ordered. It has been many, many months ago that I ordered these. Phones are still going strong.
Wireless home phone rejuvenated at a very good price. Save many dollars over in store brands. Well worth the time to find them on line.
the product is perfect for my phone. I  am so glad u sell it.i would have had to buy a new phone and wall phones are almost impossible to buy  this was my firs time using the amazon site. it was a great site to use easy, fast response etc etc. I have used many sites but amazon will always be my first choice now.
Replacement battery, came fully charged and ready to go.
It's a battery, so not much else to say other than it fit the phone and charged up very quickly.
Good replacement battery. Holds charge for a decent amount of time.
Battery lasted 7 months, I guess that is $4 worth.
Answer: do not get these batteries! they are garbage! only lasted two months, the supplier says they are guaranteed for two years, but they don't hold a charge. the supplier will not refund my money or replace the batteries, just give me false hope via e-mail. do not buy these from this company!!!!!
