Battery Construction; Electrolyte Filling - PGO G-MAX 50 Service Manual

BATTERY
CONSTRUCTION
PGO sscooters uses an MF (Maintenance Free) battery.
As shown in the right illustration, the battery consists of
electrodes, separators, safety valve, filter, etc. Fine glass
fiber is used for constructing the separator which holds
electrolyte inside.
When a discharged conventional open type battery is re-
charged fully, lead sulfate turns to lead dioxide and sponge-
like lead. If recharging is further continued, charging cur-
rent is consumed for electrolytic action producing oxygen
gas from the positive and hydrogen gas from the negative
electrodes. This causes electrolyte to be lost thereby re-
quiring addition of water.
In an MF battery, however, no water loss is caused. In this
Battery, the negative electrode is designed not to fully turn
To lead (sponge-like lead) even under fully charged condi
tion. For this reason, the negative electrode remains always in non-complete charged condition producing
no hydrogen gas. Oxygen gasses produced at the positive electrode will immediately react
With an active material (lead) at the negative electrode to turn back to water, thus preventing water
from losing.
PRECAUTION WHEN HANDLING BATTERY ELECTROLYTE
Take most care so as not to cause battery acid to contact a person and the vehicle.
If battery acid has contacted the skin, clothes or vehicle, immediately flush with plenty of water. If
battery acid remains contacted, burns of skin, damage to clothes, peeling or discoloration of paint
will occur.
Should battery acid gets in eyes, immediately flush with
plenty of water and call physician.

ELECTROLYTE FILLING

! CAUTION
Make sure to use electrolyte specified for each
Battery type.
Using electrolyte designed for other battery type can cause
Electrolyte leak, performance deterioration or shortened life.
Remove the aluminum tape
electrolyte filler holes
Remove the cap from the electrolyte container.
!CAUTION
Handle the removed cap carefully after filling
electrolyte as the cap is reused for sealing the
battery filler holes.
Do not remove or pierce the sealed areas
the electrolyte container.
