The Yamaha VK540E M II III uses a YB16AL - conventional (flooded, serviceable). Around 210 CCA of cold-start current. Meeting or beating the OEM rating is fine; going under it can cause hard starts in the cold. About 16 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 Yamaha VK540E M II III take?

The Yamaha VK540E M II III takes a YB16AL battery, a conventional (flooded, serviceable) rated around 210 CCA and 16 Ah.

Is the YB16AL an AGM or lithium battery?

Conventional (flooded, serviceable). You can also fit a LiFePO4 lithium drop-in in the same YB16AL case size for less weight and longer life - just use a lithium-aware charger.

How many cold cranking amps (CCA) does it need?

Around 210 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 Yamaha VK540E M II III?

Yes. Lithium (LiFePO4) drop-ins are made in the same YB16AL 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 Yamaha VK540E M II III?

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.
