INITIAL CHARGING
Filling electrolyte
• Remove the aluminum tape 1 sealing the battery electrolyte
filler holes A.
NOTE:
When filling electrolyte, the battery must be removed from the
vehicle and must be put on the level ground.
• Remove the caps 2.
NOTE:
* After filling the electrolyte completely, use the removed cap 2
as sealing caps of battery-filler holes.
* Do not remove or pierce the sealed areas 3 of the electrolyte
container.
• Insert the nozzles of the electrolyte container 4 into the battery’s
electrolyte filler holes, holding the container firmly so
that it does not fall. Take precaution not to allow any of the
fluid to spill.
• Make sure air bubbles 5 are coming up each electrolyte container,
and leave in this position for about more than 20 minutes.
Type designation YT12A-BS
Capacity 12V,36kC (8Ah)/10 HR
SNOTE:
If no air bubbles are coming up from a filler port, tap the bottom
of the electrolyte container two or three times.
Never remove the container from the battery.
• After confirming that the electrolyte has entered the battery
completely, remove the electrolyte containers from the battery.
Wait for about 20 minutes.
• Insert the caps 6 into the filler holes, pressing in firmly so that
the top of the caps do not protrude above the upper surface of
the battery’s top cover.

For initial charging, use the charger specially designed for MF battery.

* Never use anything except the specified battery.
* Once the caps have been installed to the battery, do
not remove the caps.
* Do not tap the caps with a tool such as hammer
when installing them.
CORRECT INCORRECT
* For charging the battery, make sure to use the charger specially designed for MF battery. Otherwise,
the battery may be overcharged resulting in shortened service life.
* Do not remove the cap during charging.
* Position the battery with the cap facing upward during charging.
Visually inspect the surface of the battery container. If any signs
of cracking or electrolyte leakage from the sides of the battery
have occurred, replace the battery with a new one. If the battery
terminals are found to be coated with rust or an acidic white
powdery substance, clean the battery terminals with sandpaper.
RECHARGING OPERATION
• Using the multi circuit tester, check the battery voltage. If the
voltage reading is the 12.0 V (DC) and less, recharge the battery
with a battery charger.
A Charging period
B Stop charging

Recharging time: 5 A for 1 hour or 1.2 A for 5 to 10 hours

• After recharging, wait for 30 minutes and more and check the
battery voltage with a multi circuit tester.
• If the battery voltage is the 12.5 V and less, recharge the battery
again.
• If battery voltage is still 12.5 V and less, after recharging,
replace the battery with a new one.
• When the motorcycle is not used for a long period, check the
battery every 1 month to prevent the battery discharge.
* When recharging the battery, remove the battery
from the motorcycle.
* Do not remove the caps on the battery top while
recharging.
Be careful not to permit the charging current to
exceed 5 A at any time
