After charging, close the vent plug , and it only can be put into use after its surface is cleaned clear.
Balanced charge
When in use, nonuniformity of voltage capacity, electrolyte and concentration may occur. Through
balanced charge, such nonuniformity can be eliminated, and all cells in the battery can be of uniform
conditions. Balanced charge is essential monthly for the batteries in use or following situation:

Cells whose discharge voltages are usually below the final voltage (1.7V/cell).

Cells with heavy discharge current (in circumstances where the drive motor and lift motor
operate synchronously with heavy load), or in circumstance with steep slope.

Cells not timely recharged after discharged.

Undercharged cells of cells not used for along time.
METHODS OF BALANCED CHARGE:
Normally charge the cells, when it is fully charged, shut off the charge power supply, keep it still for half
an hour, then switch on the power supply and continue to charge with the current of phase 2. When air
bubbles come out, convert to 1/2 of the current of phase 2 and continue to charge the cells, when air
bubbles are produced, shut off the charge power supply, keep is still for half an hour, then switch on the
power supply and continue to charge with 1/2 of the current of phase 2, until air bubbles are produced,
stop charging and left it still. Repeat the procedure for several times, until air bubbles are produced as
soon as power supply is connected. In balanced charge, voltage of each cell as well as the electrolyte
concentration should be measured and recorded. Before the charge is completed, the electrolyte
concentration and height should be adjusted to the prescribed parameters.
