Storage Time (months)
5.1 STORAGE IN HOT ENVIRONMENTS
(GREATER THAN 90ºF OR 32ºC)
Avoid direct exposure to heat sources, if possible, during storage. Batteries self-dis-
charge faster in high temperatures. If batteries are stored during hot, summer months,
monitor the specific gravity or voltage more frequently (approximately every 2-4
weeks). Refer to the self-discharge graph above and the freezing point graphs on the
next page for more info.
5.2 STORAGE IN COLD ENVIRONMENTS
(LESS THAN 32ºF OR 0ºC)
Avoid locations where freezing temperatures are expected, if possible, during storage.
Batteries can freeze in cold temperatures if they are not fully charged. If batteries are
