CHARGE PERIOD

The approximate required time to bring a battery to full charge state depends upon the number of ampere hours (AH) depleted from the battery. AHs are determined by multiplying the number of hours by the number of amps supplied to a load.

For example - If a load was connected to a battery, which drew 7 amps for a period of 5 hours, the battery will have supplied 35 AH. The approximate recharge time would then be calculated by dividing the 35 AH depleted from the battery, by the ampere charge rate of the charger. To allow for tapering off of the charge rate, add 25 percent to the charge time.

Indications of a fully charged battery are:

1.When the meter indicates an intermittent current flow to the battery.

2.A hydrometer reading of the specific gravity of the electrolyte (fluid) of a battery in good condition should be between 1.250 and 1.285.

3.When a battery reaches 80-85% of full charge, bubbles will appear on the surface of the fluid. As the battery nears full charge, bubbling will become more noticeably active.

4.The time required to charge two 6-volt batteries connected in series will be the same as for one 12-volt battery of equivalent size.

NOTE: This charger will shut off when the battery is fully charged and will turn back on automatically when the battery needs to be charged again.

5.Do not charge two 12-volt batteries in parallel.
