Note: The following page is for vehicles with battery’s containing separate electrolyte pack. Most
battery’s will come with the electrolyte already sealed into the battery.
Preparing the battery:
· Place battery on level surface. Remove sealing tape
from top. (see gure 20)
· Take the electrolyte container out of the plastic bag.
· Place electrolyte container upside down with the
sealed silver mouths of the electrolyte bottles in line
with the six ller holes of the battery. (see gure 21)
· Push the container down strongly enough to break the
silver seals.
· As electrolyte starts owing into battery, air bubbles
will come up from the mouths of the plastic electrolyte
bottles.
· Leave bottles upside down in battery holes until
electrolyte is completely drained.
· Never leave children unattended around battery.
· If air bubbles cease to oat to the top of the electrolyte
bottles, tap lightly on top.
· DO NOT remove container from battery while it is
draining.
· Never cut or pierce electrolyte container.
· After all the electrolyte has drained from the bottles
into the battery, pull plastic electrolyte bottles gently
out of the battery.
· Discard empty electrolyte bottles in a waste area that
is inaccessible to children and animals.
· After lling let battery stand for at least 30 minutes
before charging. This allows the electrolyte to
penetrate plates for optimum performance and ensures
longer battery life.
· After 30 minutes the battery is ready for its initial
charge. Place cap strip loosely over the lling holes as
shown in the picture. (see gure 22)
