The most common mistake made by purchasers of sealed, maintenance-free batteries is that they feel that no care is necessary since they are maintenance-free.  This is almost true except for maintaining a charge on your battery.  The worst thing you can do to any battery is allow the battery to go into a prolonged period of deep discharge.  Often, the battery will fail to charge again.  This usually happens during off-seasons when no riding occurs.  You will extend your battery life by using a battery charger (sometimes called a battery maintainer) to keep your battery charged when you are not riding (see Seasonal Riding below).  Your battery life can be shortened dramatically by allowing the battery to deeply discharge.  However, the type of charger is very important.  Listed below are the requirements for properly charging your battery.

Seasonal Riding ... If you are a seasonal rider, we recommend removing your battery from your Power Sport vehicle and storing the battery in a climate controlled environment, if possible.  Your automatic battery charger should remain connected to your battery throughout the non-riding season which will keep your battery peaked and will not allow your battery to go into a deep discharge.  Otherwise, put a full charge on your battery every 4 weeks during long periods of not riding.  REMEMBER, ALLOWING YOUR SEALED POWER SPORT BATTERY TO DEEPLY DISCHARGE SHORTENS THE LIFE OF THE BATTERY and WILL VOID YOUR WARRANTY.
