16-28 ELECTRICAL SYSTEM
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.
Charging Condition Inspection
Battery charging condition can be checked by measuring
battery terminal voltage with a digital voltmeter [A].
Seats (see Seats section in the Frame chapter)
Disconnect the battery terminals.
Be sure to disconnect the negative (–) cable first.
Measure the battery terminal voltage.
Measure with a digital voltmeter which can be read one
decimal place voltage.
If the reading is 12.8 V or more, no refresh charge is re-
quired, however, if the read is below the specified, refresh
charge is required.

Terminal Voltage (V) [A]
Battery Charge Rate (%) [B]
Refresh charge is required [D]
Remove the battery [A] (see Battery Removal).
Do refresh charge by following method according to the
battery terminal voltage.
This battery is sealed type. Never remove sealing
cap [B] even at charging. Never add water. Charge
with current and time as stated below.
