3.4 Charging & Equalizing
3 . 4 .1 Charging
Proper charging is imperative to maximize battery performance. Both under- or over-charging batteries
can signicantly reduce the life of the battery. For proper charging, refer to the instructions that came
with your equipment. Most chargers are automatic and pre-programmed. Some chargers allow the user
to set the voltage and current values. Refer to Table 4 for charging guidelines and to Diagram 4 for Trojan’s
recommended deep-cycle ooded/wet charging guidelines. Refer to the deep-cycle AGM charging
guidelines (Table 5) and to Diagram 5 for Trojan’s recommended deep-cycle AGM charging guidelines.
Refer to the deep-cycle gel charging guidelines (Table 6) and to Diagram 6 for Trojan’s recommended
deep-cycle gel charging guidelines.
î Make sure the charger is set to the appropriate program for deep-cycle ooded/wet, AGM or gel,
depending on the type of battery you are charging.
î Batteries should be fully charged after each use.
î Lead-acid batteries (deep-cycle ooded/wet, AGM or gel) do not have a memory eect and
therefore do not need to be fully discharged before recharging.
î Charge only in well-ventilated areas.
î Check electrolyte level to make sure plates are covered with water before charging (deep-cycle
ooded/wet batteries only). Refer to section 3.2.
î Check that all vent caps are secured properly on the battery before charging.
î Deep-cycle ooded/wet batteries will gas (bubble) towards the end of charge to ensure the
electrolyte is properly mixed.
î Never charge a frozen battery.
î Avoid charging at temperatures above 120°F (49°C).
