Always make sure a battery is fully charged before placing it into storage.
Never charge batteries in a gas-tight container.
Always store batteries in a cool, dry location. Optimum temperature is 25°C (77°F).
Always monitor battery, open-circuit voltage at least once every 12 months. If not using a

battery, refer to the manufacturer’s guidelines for storage.
Always provide a refreshing charge if the open circuit voltage drops below 12.2 volts.
Always make sure a battery is fully charged prior to placing it into service.
Never mix batteries that are at different states of charge. (Refer to battery date codes)
Make sure that the open circuit voltage for each battery in a string is greater than 12.8
volts.
Never mix battery types or batteries that are at different states of charge.
A different state of charge condition likely exists if the open circuit voltage for any battery in
a string deviates from its neighbor by more than ± 0.25 volts.
Never leave a battery in a discharged state for any length of time.
Never forget to periodically check batteries for proper terminal attachment torque every 12
months.
