4.3 Cleaning
Check the battery for cleanliness at regular intervals and keep terminals and connectors free of corrosion.
Terminal corrosion may adversely aect the performance of the battery and present a safety hazard.
î Check that all vent caps are secured properly on the battery.
î Clean the top of the battery, terminals and connections with a cloth or brush, and a solution of
baking soda and water (1 cup of baking soda to 1 gallon of water).
Do not allow cleaning solution to get inside the battery.
î Rinse with water and dry with a clean cloth.
î Apply a thin coat of terminal protector spray that can be purchased through your local battery dealer.
î Keep the area around batteries clean and dry.
4.4 Charging & Equalizing
4.4.1 Boost Charging
The term boost charging refers to fully charging your batteries before they are used or when they are in
storage.
Flooded Batteries
Two methods can be used to boost charge ooded batteries, either automatically or manually. If
using the automatic method (charger is preprogrammed), simply allow the charger to go through the
complete charge cycle.
If you use the manual method (charger has adjustable settings) follow the steps below:
î Boost charge at CONSTANT CURRENT, without voltage limit, at 3% of C until the voltage stops
increasing for three consecutive hourly readings. If using CONSTANT VOLTAGE, the recommended
boost charge voltage is 2.45 2.58 V/cell with the charger output current limited to 3 - 5% of C.
Using voltages at the lower end of this range will result in an extended boost time.
î The boost charge is not complete until the specic gravity readings of each cell remain constant over
three successive hourly readings and all cells are gassing freely. If you have questions concerning
boost charging, contact Trojan Battery Company Technical Support.
