Battery
Initial Charge
Place the strip [A] of caps loosely over the filler ports.
Newly activated sealed batteries require an initial charge.
Standard Charge
1.8 A × 5 10 hours
If using a recommended battery charger, follow the
charger’s instructions for newly activated sealed battery.
Kawasaki-recommended chargers
Optimate III
Yuasa 1.5 Amp Automatic Charger
Battery Mate 150-9
If the above chargers are not available, use equivalent
one.
NOTE
Charging rates will vary depending on how long the
battery has been stored, temperature, and the type of
charger used. Let battery sit 30 minutes after initial
charge, then check voltage using a voltmeter. If it is
not at least 12.6 volts, repeat charging cycle.
After charging is completed, press down firmly with both
hands to seat the strip of caps [A] into the battery (don’t
pound or hammer). When properly installed, the strip of
the caps will be level with the top of the battery.
CAUTION
Once the strip of the caps [A] is installed onto the
battery, never remove the caps, nor add water or
electrolyte to the battery.
NOTE
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 12.6 volts repeat the
charging cycle and load test. If still below 12.6 volts the
battery is defective.
Precautions
1) No need of topping-up
No topping-up is necessary in this battery until it ends its life under normal use. F
orcibly prying off the
seal cap to add water is very dangero u s. Never do that.
2) Refreshing charge
If an engine will not start, it indicates the battery has been discharged. Give refresh charge for
5 to 10 hours with charge current shown in the specification (see this chapter).
When a fast charge is inevitably required, do it following precisely the maximum charge current
and time conditions indicated on the battery.
CAUTION
This battery is designed to sustain no unusual deterioration if refresh-charged according
to the method specified above. H
owever, the battery’s performance may be reduced no-
ticeably if ch a rged under conditions other than given above. Ne v er 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.
