[9] CHECK POINTS FOR EVERY 1 OR 2 MONTHS

Recharge of Battery
CAUTION
• The battery gas can cause an explosion. Keep the sparks
and open flames away from the battery at all times,
especially when you charge the battery.
• When you charge the battery, remove the battery vent
plugs.
• When you disconnect the cable from the battery, start with
the negative terminal first. When you connect the cable to
the battery, start with the positive terminal first.
• Do not put an object made of metal across the terminals to
do a test on the battery charge. Use a voltmeter or
hydrometer to do a test on the battery charge.
1) Slow Charge
1. Add distilled water if the electrolyte level is low. When you
charge, the quantity of electrolyte must be lower than the
specified level to make sure that it does not spill.
2. Connect the battery to the charging unit, obey the manufacturer
instructions.
3. When you charge, remove all vent plugs to release the battery
gas.
4. The electrolyte temperature must not be more than 40 °C
(104 °F) when you charge.
If it is more than 40 °C (104 °F), decrease the charging
amperage or do not charge for a while.
5. When you charge a few batteries in series, charge at the rate of
the smallest battery in the line.
2) Quick Charge
1. Find the correct current and time to charge at with the tester
attached to the quick charger.
2. Find the correct current that you charge at as 1/1 of the battery
capacity. If the battery capacity is more than 50 Ah, use 50 A as
the maximum.
Precaution when you operate a Quick Charger
• The type of quick charger is different on its operation.
Refer to the instruction manual.
