Cb..cdiOl: the Banery Charge Status
If you suspect a problem with the battery, use a bydrometer to
measure
me
"specific gravity" of the battery electrolyte. The
higher the reading on the hydrometer, the closer your battery is
to full charge. If you do not have a hydrometer, see your
Honda dealer.

Use a battery charger with a charging rate that is ten percent
(10 %) of the battery's ampere hour rating (page
J
85). For
example, if your battery's ampere hour rating is 12 AH
(ampere hours), the charging rate should not exceed 1.2 amps.
A higher charging rate will cause the battery to overheat.
We recommend using a "trickle" charger for home charging.
These units can be left connected for long periods without
risking damage to the battery. However, do not intentionally
leave the charger connected longer than the time period
recommended in the charger's instructions.
Avoid using an automotive-type battery charger. An
automotive charger can overheat a motorcycle battery and
cause pennanenl damage.
