FAQ:

1.Q/ What is the difference between lithium and lithium ion batteries?  

A/The biggest differences are that lithium batteries contain lithium metal and are not rechargeable. Lithium ion batteries, however, do not contain lithium metal and can be recharged.

2.Q/ Do Li-ion batteries develop a memory? Do I need to recharge after every use?

A/ No, While older styles of battery did develop a “memory”, the new Li-ion batteries do not.

3.Q/What’s the nominal voltage of a polymer lithium battery

A/ The nominal voltage of a polymer lithium battery is 3.7 V.

4.Q/What’s the highest charge of a polymer lithium battery

A/ The highest voltage of a polymer lithium battery is 4.2 V.
