• The quantity of electrolyte varies with the type
of the electrolyte container.
• Avoid using any electrolyte other than specified. 2 . Check:

d. Detach the strip of caps (used as battery plugs).
Six sealed areas of container

Do not lose the strip of caps because it will be used


as battery plugs.

Do not peel or pierce the sealed areas.

e. Turn the electrolyte container upside-down with


the six sealed areas in line with the six filler ports
of the battery.
f. Push the container down with enough force to
break the seals. The electrolyte will start to flow
into the battery.

• Do not tilt the container as the electrolyte may


stop flowing.
• Never remove the container from the battery
until all electrolyte has drained from the container.

g. Leave the container in this position for 20 minutes


or longer to allow proper chemical reaction.

• Make sure air bubbles are rising from all six filler
ports.
• If air bubbles are not rising from a filler port, tap
the top of the container a few times.

h. Make sure that all the electrolyte has been drained


from the container.
i. Fit the strip of caps (battery plugs) securely into
the filler ports. Make sure the top of the strip is
flush with the top of the battery.
Press down with equal force with both hands.

• Never remove the strip of caps, nor add any


water or electrolyte.
