Battery
134 Servicing Your Honda
Battery
Refer to Important Safety Precautions on page 23.
Your CRF has a lithium-ion (li-ion) battery.
Clean the battery terminals if they become dirty or
corroded.
An improperly disposed of battery can be harmful
to the environment and human health.
Always confirm local regulations for proper
battery disposal instruction.
Power of the start button uses current from the
battery.
Limited operation also allows the battery to
discharge. If you do not ride frequently, we
recommend that you charge the battery frequently
(see Battery Charging on page 135).
If you plan to store your CRF, see Battery Storage
(this page).
If your battery seems weak and/or is leaking
electrolyte (cause slow starting), see your dealer.
If you smell an unusual odor coming from the
lithium-ion (li-ion) battery, park your CRF in a
safe place outside and away from flammable
objects, then push and hold the engine stop button
until the engine stops completely.
The battery has a limited life span.
Consult your dealer about when you should
replace the battery. Always replace the battery
with another lithium-ion (li-ion) battery of the
same type.
The lithium-ion (li-ion) battery contains a fuse
inside.
If the fuse blows, the battery needs replacement.
The voltage may read above 12V even with a
blown battery fuse when the battery is unmounted
(page 169).
Before you remove the battery, be sure to read all
the information that follows, as well as the
information on the battery label.
If you do not remove the battery, we recommend
disconnecting the battery cables (negative cable
first).
The battery is located under the seat.

off the floor, in an area protected from freezing
temperatures and direct sunlight.
