8.1 Recharging battery

CAUTION
• When the battery is being activated, hydrogen
and oxygen gases in the battery are extremely
explosive. Keep open sparks and flames away
from the battery at all times, especially when
charging the battery.
• When charging battery, remove battery vent
plugs.
• When disconnecting the cable from the battery,
start with the negative terminal first. When
connecting the cable to the battery, start with
the positive terminal first.
• Never check battery charge by placing a metal
object across the posts.
Use a voltmeter or hydrometer.
Precaution for operating a quick charger
• Operate with a quick charger differs according to
the type.
Consult the instruction manual and use accordingly.
Slow charging
1. Add distilled water if the electrolyte level is low.
When charging, the amount of electrolyte should be
slightly lower than the specified level to prevent
overflow.
2. Connect the battery to the charging unit, following
the manufacture's instructions.
3. As the electrolyte generates gas while charging,
remove all port caps.
4. The electrolyte temperature must not exceed 40 ℃
(104 ℉) during charging.
If it exceed 40 ℃ (104 ℉), decrease the charging
amperage or stop charging for a while.
5. When charging several batteries in series, charge
at the rate of the smallest battery in the line.
