How do you recharge a lithium battery?

I have a Nikon coolpix 4200. The battery in it is a "Lithium Ion battery pack EN-EL5 3.7 V 1100mAh" battery. In order to keep the longest battery life, should I let the battery die, or is it ok to recharge before it dies?

• Answer:

  Depends on hof often you use it. If you use your battery regularly, you should not fully discharge it. However, if you rarely ever use it, you should do a full discharge-recharge cycle once a month. Not using Li-Ion-batteries can have adverse effects on them.
