The new Li-Ion battery is not at 0% charge when it gets to you, optimum storage is 40% and the batt probably has that amount of charge.

You should never ever overcharge a Li-Ion battery, and the built-in protection circuitry in the batt will prevent it anyhow. There's little truth behind the "first time charge" theory, as Li-Ion batteries have zero memory effect.

It means nothing really. On a full charge, the battery's potential difference is actually around 8.30V (the battery then proceeds to discharge across an entire range of voltage under load). To a layman, the voltage numbers don't mean much, the mAh ratings are more significant though, the higher the better of course.
I have little idea where this myth originated from, but a little research will reveal much. Overcharging is never good for any form of rechargeable batteries. For Ni-MH, a good charger will not overcharge the batt, but instead provide a nice trickle current to keep the batt topped up (Ni-MH batts have a high self-discharge rate). The problem with this is that some chargers have a rather high trickle current, and this will adversely affect the performance of the batt over time. Thus it's safest to charge your Ni-MH batts, use them straightaway, or give them a top-up charge before using them if they have to be stored away for prolonged period of time.mr_jason said:
Do check out the website, it goes into good detail, at the same time not too technical to comprehend.
