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 safety valve
operates to keep the battery safe.
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 lead 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 gases.
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 medical 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.
Charging Condition Inspection
Battery charging condition can be checked by measuring
battery terminal voltage.
Remove the seats (see Frame chapter).
Disconnect the battery leads.
Be sure to disconnect the negative (–) lead first.
Measure the battery terminal voltage.
