Mighty Max Battery ML-U1 12V 200CCA Battery for Ariens Zoom 2350 0Turn Lawn Mower

What It Is

The Mighty Max Battery ML-U1 is a 12V, 200 CCA (cold cranking amps) sealed lead-acid battery designed to replace the OEM battery in Ariens Zoom 2350 zero-turn mowers and similar lawn tractors. It powers the starter motor and provides electrical supply for lights and accessories.

Fitment & Compatibility

Before buying, confirm these specifics:

• Model fit: Designed for Ariens Zoom 2350 (and many Zoom models with U1 group size). Check your owner’s manual or existing battery label for “U1” group size.
• Dimensions: 7.7” L x 5.1” W x 6.1” H – measure your battery tray to ensure it fits. Slightly taller than some OEM batteries; verify clearance under the seat or hood.
• Terminals: Standard SAE automotive posts (positive left, negative right when facing terminals). No adapter needed for most Ariens cables.
• CCA rating: 200 CCA is sufficient for most residential zero-turn engines (typically 12-18 HP). If your mower has a larger engine or you mow in cold climates, consider a higher CCA battery.

Key Things to Know

• Sealed/AGM: This is an absorbed glass mat (AGM) battery – no maintenance, no acid spills, and works in any orientation (except upside down). Good for vibration-prone mowers.
• Installation difficulty: Easy – disconnect negative first, then positive, swap battery, reconnect positive then negative. Takes 10 minutes with basic wrenches.
• Common gotcha: The ML-U1 is slightly taller than some OEM batteries. If your battery hold-down bracket is fixed, you may need to shim it or adjust the bracket. Check clearance before tightening.
• Warranty: Mighty Max offers a 1-year warranty – keep your receipt. If the battery fails within that period, contact them directly for replacement.

Should You Buy It

If your Ariens Zoom 2350 needs a reliable, no-maintenance battery and you’re comfortable with a simple swap, this is a solid budget-friendly choice. It’s especially good for warmer climates or occasional use where 200 CCA is enough. Avoid if you need higher cold-cranking power for frequent winter starts or if your battery tray can’t accommodate the slightly taller case.
