If more than 20 minutes, stop charging and

Reverse battery connections. Shut off charger and correct lead connections.
The approximate time required to bring a battery to a full charge state depends upon the number of ampere hours (AH’s) depleted from
the battery. AH’s are determined by multiplying the number of hours time the number of amps supplied by the battery to the load. For
example- If a load was connected to battery which drew 7 amperes for a period of five hours, the battery will have supplied 35 AH. The
approximate recharge time would be calculated by dividing 35 AH depleted from the battery, by the ampere charge rate of the charger.
To allow for tapering of the charge rate add 25% to the charge time.
A hydrometer reading of the specific gravity of the electrolyte (fluid) of a battery in good condition should be between 1.25 and 1.285.
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 vigorous.
Storage: Store the battery charger in a dry area.
