Well, it is a lithium battery. Charging it wrong is bad, as lithium can
explode and burn.
But I have the impression that just about any charger made for lithium
batteries of similiar capacity should work safely. A normal lithium
charger should monitor the voltage and stop when the battery gets full.
A charger made for much bigger batteries could charge too fast and be
You have to figure out the battery terminals, but that should be
possible as FR schematics is available. There is a ground terminal, a
terminal that the phone draws power from, and a third terminal that is
used for charging.
Make sure any charger you try to use is made for charging batteries
only. Many phone chargers are cheap devices made for connecting to a
phone, and the phone's electronics will limit charging for you. such a
charger can not be used for a battery without a phone.
If you can get your hands on one of those freerunners with a broken
display, then that can be used as a "charger" too.
