Aprilia Pegaso Battery
The Aprilia Pegaso (650cc) takes a YT12CL battery, about 165 CCA and 12 Ah. It is a conventional (flooded, serviceable), and a lithium drop-in fits the same case.
Key takeaways
- Battery: YT12CL (also sold as YB12AL-A).
- Conventional (flooded, serviceable), around 165 CCA, 12 Ah.
- Lithium drop-in fits the same YT12CL case - lighter, longer-lived, needs a lithium charger.
- Covers 1991-2004 (battery changed across years - see table).

The Aprilia Pegaso uses a YT12CL - conventional (flooded, serviceable). Around 165 CCA of cold-start current. Meeting or beating the OEM rating is fine; going under it can cause hard starts in the cold. About 12 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 Aprilia Pegaso take?
The Aprilia Pegaso takes a YT12CL battery (also sold as YB12AL-A), a conventional (flooded, serviceable) rated around 165 CCA and 12 Ah.
Is the YT12CL an AGM or lithium battery?
Conventional (flooded, serviceable). You can also fit a LiFePO4 lithium drop-in in the same YT12CL case size for less weight and longer life - just use a lithium-aware charger.
How many cold cranking amps (CCA) does it need?
Around 165 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 Aprilia Pegaso?
Yes. Lithium (LiFePO4) drop-ins are made in the same YT12CL 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 Aprilia Pegaso?
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.
