Note:
(1) When the depth of discharge is large (usually more than 5~10% C
10
), it is recommended to use the equalization voltage,
so that this charge mode is more adequate. When charges for 24 hours or the current drops below 0.005C
10
A, and the current
value is substantially constant for three consecutive hours, the charge is considered complete.
(2) The battery needs to be fully charged as soon as possible, the charge current can be increased appropriately, but it cannot
be higher than recommend value.
(3) If the battery is not recharged in time after discharge, or the power is off again during recharge, the insufficient-charged
batteries will be frequently discharge, thus the batteries will lose part of capacity in short period. And it may cause capacity
loss at initial stage and the batteries will be rejected if the situation is serious.
Battery recharge method
Step 1: Connect the batteries in series, and ensure that the bolts and screws are fastened.
Step 2: Connect the positive and negative poles of the battery to the positive and negative poles of the charging device.
Step 3: Turn on the charging power supply, set the charging current limit value and charging voltage value according to the
supplementary power requirements;
