To ensure maximum battery life and customer satisfac-
tion, it is recommended the battery be load tested at
three times its amp-hour rating for 15 seconds.
Re-check voltage and if less than 12.8 V repeat the
charging cycle and load test. If still below 12.8 V the
battery is defective.
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 Specifications in this chapter).
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-
Keep the battery away from sparks and open flames during charging, since the battery
gives off an explosive gas mixture of hydrogen and oxygen. 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
No fire should be drawn near the battery, or no terminals should have the tightening loos-
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. Get medial attention if severe.
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.
