7 Maximizing 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 to more than 80% depth of discharge. 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.
8 What to Expect from Your Trojan Battery
î A new deep-cycle battery will not immediately deliver its full rated capacity. This is normal and
should be expected since it takes time for a deep-cycle battery to reach peak capacity.
î Trojan’s deep-cycle AGM and gel batteries will reach rated capacity in less than 20 cycles.
î Trojan’s deep-cycle ooded batteries take 50 - 100 cycles to achieve full, peak capacity.
î When operating batteries at temperatures below 80°F (27°C), they will deliver less than the rated
capacity. For example at 0°F (-18°C) the battery will deliver 50% of its capacity and at 80°F (27°C) it
will deliver 100% of its capacity.
î When operating batteries at temperatures above 80°F (27°C), they will deliver more than the rated
capacity but battery life will be reduced.
î The life of a battery is difficult to predict and will vary by application, frequency of usage and
level of maintenance.
