Battery Storage Practices
1. Batteries should be stored in a cool, dry location, protected from the
elements. Wind chill factors have been known to freeze batteries which
would not freeze at normal ambient temperatures. Direct exposure
to heat sources, such as radiators or space heaters, will accelerate the
rate of self-discharge and increase the frequency of required boost
charging. Exposure to direct sunlight may result in fading of colored
cases and covers.
2. According to Battery Council International, batteries in storage should
be given a boost or freshening charge when the specific gravity value
drops .040 points. When hydrometer readings are not accessible, open
circuit voltage readings may be used. While in storage, a freshening
charge should be given when the battery voltage drops below
12.4 volts for a 12 volt battery, or 6.2 volts for a 6 volt battery. Table
2 shows open circuit voltage values at various states of charge and
recommended recharge times at various charge current rates.
3. If the batteries have been in service prior to storage, they should be
given a boost charge before being placed in storage and immediately
prior to returning to service.
Proper storage of Trojan deep cycle, lead acid batteries will help achieve
better performance and longer life, while increasing reliability and value to
the end user.
