Yamaha TT-R110E Battery
The Yamaha TT-R110E (110cc) takes a YT4B-BS battery, about 40 CCA and 2.3 Ah. It is a sealed agm (maintenance-free), and a lithium drop-in fits the same case.
Key takeaways
- Battery: YT4B-BS (also sold as YT4B).
- Sealed AGM (maintenance-free), around 40 CCA, 2.3 Ah.

The -BS suffix means it ships dry with an acid pack you add once - after that it is a sealed, maintenance-free AGM battery.
The Yamaha TT-R110E uses a YT4B-BS - sealed agm (maintenance-free). Around 40 CCA of cold-start current. Meeting or beating the OEM rating is fine; going under it can cause hard starts in the cold. About 2.3 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.

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 TT-R110E take?
The Yamaha TT-R110E takes a YT4B-BS battery (also sold as YT4B), a sealed agm (maintenance-free) rated around 40 CCA and 2.3 Ah.
Is the YT4B-BS an AGM or lithium battery?
Sealed AGM (maintenance-free). The -BS suffix means it ships dry with an acid pack you add once - after that it is a sealed, maintenance-free AGM battery. You can also fit a LiFePO4 lithium drop-in in the same YT4B-BS case size for less weight and longer life - just use a lithium-aware charger.
How many cold cranking amps (CCA) does it need?
Around 40 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 TT-R110E?
Yes. Lithium (LiFePO4) drop-ins are made in the same YT4B-BS 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 TT-R110E?
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.
