Li Ion Battery & charger info for beginer

[Dr Jekell]

Right, as I haven't found this info else were I will ask here.

Mr Hyde decides to get a new light (Novatac EDC 120P FYI) and he decides to get an AW Protected RCR123A battery & charger for his new light to experience the legendary "Guilt free lumen's".

When he looks in the respected encyclopedia "CandlePower Forums" he was unable to find any information on what to do with the battery/charger when it arrives.

So he decided to post a thread in a horrendous story telling format to ask if the battery should be:

A) Given a top up charge prior to use, then used as normal
B) Use the battery until it is dead and then recharge it

Poor Mr. Hyde. What to do? Mr. Hyde certainly wants to play with his new toys but, alas, cannot bring himself to a decision.

It is my opinion to advise Mr. Hyde to choose option A. Mr. Hyde will be very happy.

LOL. Yes, you will receive it charged to ~40% (3.8V). Charge it until the light goes green, then take it off the charger straightaway. Then use it as normal.

If you have a DMM, it is a good idea to check your Li-Ion cells voltage before and after charge. Unlike other chemistries, voltage is a direct indicator of state of charge. 4.2V is full, and 3.5V (resting, i.e. not under load) is empty.

Charge the cell after each use. Don't let it run down to empty every time and hit the low-voltage protection cutout. Always keep an eye on the cell when it is charging, and stop the charge at once if the cell gets hot.

My concern would be advising Mr. Hyde to pursue option "A," but an unexpected connection spark triggering Dr. Jekyll to take over. We then would witness him putting the battery in a pan of water, both into the microwave, and applying full power for 30 minutes.

How about a nice game of checkers with Joshua instead?
