I keep mine topped up on a regular basis during the off season. In season, let it get to room temp and recharge asap after every use. Battery life is rated for the number of charge/discharge cycles. Also the less you run them down between charges the better. Deeply discharging a battery is bad for it's longevity. Think of bending a hanger back and forth repeatedly, (not good). Exercising a battery will just shorten the life of the battery. If you actually need to use it then that's fine but running up and down for no reason doesn't do the battery any favors.
