What kind of battery does it use? How to replace it? Am Verizon responsible for battery replacement or should I buy the battery on my own?
The above link should assist you. The customer is required to buy the battery. However they can be bought cheap at Walmart’s or online stores etc. unless you have the phone service it really is not needed. You can follow the instructions in the link to totally get rid of it.
also Verizon uses a (power reserve unit) different than a BBU in the case are “D” cell batteries which are cheap. In this case it has an on/off button so if it makes noise you can take the batteries out or just turn it off.
your jpg is not showing up yet so I gave you information for both.
