Charging

3.4.1.
Proper charging is imperative to maximize battery performance. Both under-
or over-charging batteries can significantly 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
flooded/wet charging guidelines,
charging guidelines and
guidelines.
• Make sure the charger is set to the appropriate program for flooded/wet, gel
or AGM, depending on the type of battery you are charging
• Batteries should be fully charged after each use
• Lead-acid batteries (flooded/wet, gel and AGM) do not have a memory effect
and therefore do not need to be fully discharged before recharging
• Charge only in well-ventilated areas
• Check electrolyte level to make sure plates are covered with water before
charging (flooded/wet batteries only)
• Check that all vent caps are secured properly on the battery before charging
• Flooded/wet batteries will gas (bubble) towards the end of charge to ensure
the electrolyte is properly mixed
• Never charge a frozen battery
• Avoid charging at temperatures above 120°F (49°C)
