28) Inspection of Battery
1.
Inspect battery liquid level. If lower than "LOW" mark a, add distilled
water until the level goes in between "UP" and "LOW" marks.
2. Measure specific gravity of battery liquid. Charge battery if
specific gravity is less than specified value.
Electrolyte contains sulfuric acid that is
poisonous and highly corrosive, and so it is
dangerous. Always be careful of the
following matters to prevent accident.
· Handle electrolyte carefully not to allow
adherence to any part of body, or it could
cause serious chemical burn or blindness.
· Wear protective glasses when working
near battery or handling battery.
First Aid in Emergency (if electrolyte adhere
to body)
·
Flush well with fresh water if adhered to skin.
· If gets in eye, flush well with fresh water
for 15 minutes, and have ophthalmologic
evaluation immediately.
First Aid in Emergency (if swallowed)
·
Drink much water, magnesium hydrate
solution (magnesium milk), fresh egg, or salad
oil, and have doctor's evaluation immediately.
Battery produces highly inflammable
hydrogen gas. Always be careful of the
following matters to prevent accident.
· Charge battery in well ventilated place.
· Keep battery away from fire, sparks or
flame. (such as live cigarette or operating
welding machine)
· Do not smoke or allow smoking when
handling or charging battery.
Keep battery and electrolyte out of reach of
children.
· Batteries are available with various types,
varying among manufacturers. For any
unclear matters, refer to manual attached to
battery.
· When removing battery, disconnect negative
lead first and then positive lead.
Specific Gravity of Electrolyte :
1.280 (at 20°C)
Charging Requirements
: for 12V70AH battery
Charging Current : 70AH - = 7A
Charging Hours : 70AH ÷ 7A = 10H
Battery :
12V70AH - 12V100AH
