I have a B&G V50/H50 combo and it looks like the handset battery
does not hold a charge anymore.
I opened it the handset and it has a 3.7 LiPo battery
inside. Is it OK to replace the battery with any 3.7v LiPo battery with the same form factor? (I couldn't find anything with the same exact markings) The battery is 850mAh. Does the replacement battery have to be exactly the same capacity, or can I get a replacement one that is "about" the same, for example 900mAh?
