I was wondering what I need to worry about for the NH-14WM battery that comes with the sony mzr-90? do i need to fully discharge the battery before i charge it or is better to "top it off" each time? will i ruin the battery if overcharge slightly? Basically, i would like to know of any ways to extend my battery life. thanks in advance ----Matt ----------------------------------------------------------------- To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
