16-26 ELECTRICAL SYSTEM
1) No need of topping-up
No topping-up is necessary in this battery until it ends its life under normal use. Forcibly prying
off the seal cap to add water is very dangerous. Never do that.
2) Refreshing charge
If an engine will not start, a horn sounds weak, or lamps are dim, it indicates the battery has been
discharged. Give refresh charge for 5 to 10 hours with charge current shown in the specification
(see Refreshing Charge).
When a fast charge is inevitably required, do it following precisely the maximum charge current
and time conditions indicated on the battery.
This battery is designed to sustain no unusual deterioration if refresh-charged according
to the method specified above. However, the battery's performance may be reduced no-
ticeably if charged under conditions other than given above. Never remove the seal cap
during refresh charge.
If by chance an excessive amount of gas is generated due to overcharging, the relief valve
releases the gas to keep the battery normal.
3) When you do not use the motorcycle for months.
Give a refresh charge before you store the motorcycle and store it with the negative cable re-
moved. Give a refresh charge once a month during storage.
4) Battery life
If the battery will not start the engine even after several refresh charges, the battery has ex-
ceeded its useful life. Replace it (Provided, however, the vehicle's starting system has no prob-
Batteries produce an explosive gas mixture of hydrogen and oxygen that can cause seri-
ous injury and burns if ignited. Keep the battery away from sparks and open flames during
charging. When using a battery charger, connect the battery to the charger before turning
on the charger. This procedure prevents sparks at the battery terminals which could ignite
any battery gases. The electrolyte contains sulfuric acid. Be careful not to have it touch
your skin or eyes. If touched, wash it off with liberal amount of water and seek medial at-
tention for more severe burns.
A sealed battery can fully display its performance only when combined with a proper vehicle electric
system. Therefore, replace a sealed battery only on a motorcycle which was originally equipped with
a sealed battery.
Be careful, if a sealed battery is installed on a motorcycle which had an ordinary battery as original
equipment, the sealed battery's life will be shortened.
