(for the purpose of uniform stirring of electrolyte by charging). If the electrolyte level is improper
after completion of charging, you may topping up the electrolyte level to the maximum level .
Determination of replenishment time and methods(cell with ONE TOUCH CAP)
Confirm the electrolyte level by looking at the float in the ONE TOUCH CAP. If too low as shown
in figure, replenish water. Replenishment shall be performed after opening the cover of the plug
using syringe and jug. When refilling is completed, close each cover completely until “click”
sound is heard. a.

Cleaning
If electrolyte spills or the cells are polluted with dust or stains, it will cause generation of leak
current. Wipe off dust and stains with moist cloth and clean in such a manner that the cells are
kept in dry condition. In the case of plastic containers or covers, never use such organic solvents
as paint thinner and gasoline. If used, the plastic containers or covers may suffer cracking. If you
are forced to use them, be sure to use white kerosene.
Notice on charging
The charging area must be well ventilated to facilitate exhaust of gas generated from the battery
during charging. Charge the battery in an area free from iron working, welding, etc. Further the
battery generates hydrogen, oxygen, acid mist and on rare occasions, hydrogen sulfide during
charging depending on the case. Special care may be required in the case of equipment and
objects near the battery that may contaminated or damaged. Do not pull out the charging plug
during charging, as it will cause sparks. Since hydrogen gas generated during charging may
remain in the area surrounding the battery after charging, never bring fire or flame close to this
area. In case of counter-balance type vehicles, open the battery cover before charging.
Repair of failure cell
To remove a cell from the circuit or battery from steel tray, it is first necessary that the intercell
connector be removed.
Before performing any repairs, you must open one-touch caps for gas purging of all cells. After
you have finished that, must remove connector covers and on-touch caps from failure cell
including surrounding cells. All vent holes of cells removed of one-touch caps must cover by
four layers of water dampened cloth and then proceed with repairs. Using an acid syringe
withdraw sufficient electrolyte from failure cell to reduce the liquid levels until minimum level
indicating of one touch caps.
The safe and most efficient method of removing a connector is with hand or electric drill(

from failure cell as well as all surrounding cells.
