- 1984-1985
The Honda XL350R uses a YT3L - conventional (flooded, serviceable). Around 35 CCA of cold-start current. Meeting or beating the OEM rating is fine; going under it can cause hard starts in the cold. About 3 Ah of capacity - the reserve that runs lights and electronics with the engine off.
AGM is the safe like-for-like: cheapest, tolerant of standard chargers and trickle tenders, and heavier. Lithium (LiFePO4) drop-ins in the same case size cut weight by roughly 60-70%, hold voltage better, and self-discharge far slower - but they cost more and need a lithium-aware charger, not an old lead-acid trickle charger.

Installing it
Disconnect the negative (-) terminal first and reconnect it last. Powersports batteries are small and light, so this is usually a 10-15 minute job with a couple of hand tools.
Frequently asked
What battery does a Honda XL350R take?
The Honda XL350R takes a YT3L battery (also sold as YB3L-B), a conventional (flooded, serviceable) rated around 35 CCA and 3 Ah.
Is the YT3L an AGM or lithium battery?
Conventional (flooded, serviceable). You can also fit a LiFePO4 lithium drop-in in the same YT3L case size for less weight and longer life - just use a lithium-aware charger.
How many cold cranking amps (CCA) does it need?
Around 35 CCA of cold-start current. Meeting or beating the OEM rating is fine; going under it can cause hard starts in the cold.
Can I put a lithium battery in a Honda XL350R?
Yes. Lithium (LiFePO4) drop-ins are made in the same YT3L case size, so they fit the tray and terminals. They weigh far less and last longer, but need a lithium-compatible charger rather than an old lead-acid trickle charger.
How do I change the battery on a Honda XL350R?
Disconnect the negative (-) terminal first and reconnect it last. Powersports batteries are small and light, so this is usually a 10-15 minute job with a couple of hand tools.
