Many motorcyclists are drawn to the use of gel-cell batteries to power their machines, due largely to their maintenance-free nature. However, these gel batteries are used very rarely with a motorcycle-based application. What motorcyclists refer to as gel batteries are really AGM (Absorbed Glass Mat) batteries, which operate on the same principle of suspended lead acid electrolyte in a permanently sealed container. And unlike a real gel-cell battery, which requires special care to charge, charging an AGM battery is a simple and uncomplicated task.
Unbolt the motorcycle's seat, using an Allen wrench, or pull off the side cover off of the motorcycle's frame to access the battery.
Unscrew the black cable from the battery's negative post, using a Phillips screwdriver. Unscrew the red cable from the battery's positive post, using a Phillips screwdriver. Lift the battery out of the motorcycle.
Connect the battery to an automatic battery charger. Place the charger's red clip on the battery's positive post, and put the black clip on the negative post.
Turn the battery charger on to begin the charging process.
Remove the battery after the charger indicates that it is fully charged. Turn off the battery charger. Remove the black clip from the battery, followed by the red clip.
Reinstall the battery in the motorcycle, following the reverse method of removal.
