the battery recharge current to the maximum value
recommended by the battery manufacturer.
M
The rectifier / charger unit shall be able to automatically adjust
the battery float charge voltage based on temperature variation
in accordance with battery manufacturer-s recommendation.
The charging current shall be adjustable from 5% to 30% so as
to limit the total input current when the battery has been
discharged.
