    i use the oem home charger that came with the droid, and i just purchased the moto oem car charger. i just wanted to make sure i'm not doing the battery harm, if i throw it on the charger at 70 or 80 percent. rather than letting it drain more before charging it.

    You won't harm it, the cells used are protected, lithium ion is a great improvement from your old nimh or nicad, they are lighter, more powerful, and they evenly discharge unlike nickel based batteries

    for example, if they only have certain number of recharges in them, it would be better to let it drain as low as possible each time and recharge to 100%. i usually just charge mine every night, regardless of its current charge.
    NiMh batteries were the ones with a limited number of charges. It roughly equated to 500 full charge/discharge cycles and the battery would degrade. With Li-Ion batteries, there is no limit to the number of charges, although I have heard that it is bad to let the battery fully discharge and then recharge too often as that speeds up the degradation of the battery. I have also heard that with Li-Ion batteries, they actually start to slowly degrade over time as soon as the battery is manufactured, so depending on how much you actually use the battery, you can expect it to last somewhere around 3-5 years until it has degraded to a point where it will essentially no longer hold a charge.
