How should I handle and maintain my sealed lead acid battery in order to get optimal performance and life time?

Please fully charge the battery BEFORE the first use: this can take 8 to 16 hours for the charger indicator light to change from red (charging) to green (charged). It is recommended to take the battery off the charger after the battery is charged, i.e. the charger light is green.
Subsequent charges of the battery: these can take from 3-8 hours, depending on load and course conditions, for the charger indicator light to turn from red (charging) to green (charged). It is recommended to take the battery off the charger after the battery is charged, i.e. the charger light is green.

Do not leave the battery on the charger for extended periods of time. Overcharging might damage the battery and will also will void the warranty.
Do not fully deplete your battery, charge after every 18 holes. Complete depletion will significantly shorten the life of the battery.
Do not secure the battery lead to the caddy with the silver battery lead screw. In case of a tip-over the battery cable should pull out to prevent damage.
Do not store the battery on concrete or other cold surfaces.
Do not store in an area that goes below freezing. During periods of inactivity, the battery should be fully recharged once every 4-6 weeks; this is a maintenance charge and should not take long. It is recommended to get a volt meter so you can measure the voltage in the battery. A new fully charged battery should read about 13.5V.

NOTE: There are times when a battery shows appropriate voltage in idle condition, yet the battery doesn't work. If this occurs, the battery should be retested under load.
