KTM EXC Battery
The KTM EXC (500cc) takes a YTZ7S battery, about 130 CCA and 6 Ah. It is a sealed agm (maintenance-free), and a lithium drop-in fits the same case.
Key takeaways
- Battery: YTZ7S.
- Sealed AGM (maintenance-free), around 130 CCA, 6 Ah.
- Lithium drop-in fits the same YTZ7S case - lighter, longer-lived, needs a lithium charger.
- Covers 2003-2016 (battery changed across years - see table).
- Chemistry (OEM)
- Sealed AGM (maintenance-free)
- Cold cranking amps (CCA)
- 130
- Capacity
- 6 Ah
- Engine
- 500cc
- Fits model years
- 2012-2016
The KTM EXC uses a YTZ7S - sealed agm (maintenance-free). Around 130 CCA of cold-start current. Meeting or beating the OEM rating is fine; going under it can cause hard starts in the cold. About 6 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 KTM EXC take?
The KTM EXC takes a YTZ7S battery, a sealed agm (maintenance-free) rated around 130 CCA and 6 Ah.
Is the YTZ7S an AGM or lithium battery?
Sealed AGM (maintenance-free). You can also fit a LiFePO4 lithium drop-in in the same YTZ7S case size for less weight and longer life - just use a lithium-aware charger.
How many cold cranking amps (CCA) does it need?
Around 130 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 KTM EXC?
Yes. Lithium (LiFePO4) drop-ins are made in the same YTZ7S 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 KTM EXC?
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.
