WARNING
Gases given off by a battery being charged
are highly explosive. Always charge in a well
ventilated area. Keep battery away from cig-
arettes or open flames. Always turn battery
charger off prior to disconnecting cables.
Otherwise a spark will occur and battery
might explode.
CAUTION: If charging rate raises higher than
2.4 A reduce it immediately. If cell temperature
rises higher than 50°C(122°F) or if the casing
feels hot, discontinue charging temporarily or
reduce the charging rate.
– Disconnect battery charger.

– If electrolyte level has dropped after charging,
fill with distilled water to UPPER LEVEL line.
After water is added, continue charging for 1 to
2 hours to mix water with electrolyte.
– Reinstall caps and clean any electrolyte spillage
using a solution of baking soda and water.
Charging a Used Battery
WARNING
Never charge battery while installed in water-
craft.
For best results, battery should be charged when
the electrolyte and the plates are at room tempera-
ture. A battery that is cold may not accept current
for several hours after charging begun.
Do not charge a frozen battery. If the battery
charge is very low, the battery may freeze. If it is
suspected to be frozen, keep it in a heated area
for about 2 hours before charging.
