Re: About battery life...

Yes it certainly does, but since you need to let the battery sit for 24hrs after the discharge to get a valid open circuit voltage, you must break the #1 rule of maximizing battery life, recharging as soon as practical after discharge. So even if the open circuit voltage rebounds to 11.0v you still have abused the battery. It is highly unlikely that there will be much rebound after a low load discharge like 20w. Typically a battery will only show significant rebound if it has be subject to a high discharge rate for a relatively short period of time.
