How can a Li-Ion cell phone battery be charged, independently of the cell phone?

Question

The battery: LG Lithium Ion 3.7V 1000mAh LGIP A 1000E

Answer 1

You need a custom made charger specifically for that battery. Lithium Ion technology is quite frankly dangerous and will catch fire if mistreated. So there are temperature sensors and all sorts of protection circuits in the phone to prevent mishaps.

The easiest way is to get another phone and put it in that to charge.
