05 Storage
î Charge batteries before placing in storage.
î Store in a cool, dry location, protected from the elements.
î Disconnect from equipment to eliminate potential parasitic loads that
may discharge the battery.
î Batteries gradually self-discharge during transit and storage, so
monitor the specic gravity or voltage in ooded batteries every 4 - 6
weeks. Monitor the open circuit voltage for AGM or gel batteries every
2 - 3 months.
î Batteries in storage should be given a boost charge when they are at
70% SOC for ooded and 75% for AGM or gel. Refer to Table 7 for specic
gravity (ooded only) and voltage measurements for ooded batteries
and AGM or gel batteries. If boosting is needed, refer to Section 4.4.1 for
boosting instructions.
î When batteries are taken out of storage, recharge before use.
5 .1 Storage in Hot Environments (greater than 90°F or 32°C)
Avoid direct exposure to heat sources, if possible, during storage. Batteries self-discharge faster in
high temperatures. If batteries are stored during hot summer months, monitor the specic gravity or
voltage more frequently (approximately every 2 - 4 weeks).
5.2 Storage in Cold Environments (less than 32°F or 0°C)
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 stored during cold winter
months, it is critical that they are kept fully charged at all times.
06 How to Maximize the Performance of your
Trojan Battery
î Follow all the procedures in this User’s Guide for proper installation, maintenance and storage.
î Do not discharge your battery more than 80%. This safety factor will eliminate the chance of over-
discharging and damaging your battery.
î If you have any questions or concerns about battery care, please contact Trojan Battery
Company’s technical support engineers at 800-423-6569 Ext. 3045 or [phone] before a
problem develops.
