Mighty Max Battery ML-U1 12V 200CCA Battery for Troy-Bilt 361113 Lawn Tractor and Mower

What It Is

The Mighty Max Battery ML-U1 is a 12-volt, 200 CCA (cold cranking amps) sealed lead-acid battery designed to start and power lawn tractors, specifically the Troy-Bilt 361113 model and similar small-engine mowers. It’s a direct replacement for the original battery in these machines.

Fitment & Compatibility

Before buying, confirm your mower uses a U1 group size battery (roughly 7.7" L x 5.1" W x 6.1" H). Check the terminal layout: the ML-U1 has positive on the left, negative on the right (when facing terminals). The Troy-Bilt 361113 lawn tractor is a direct fit, but verify your model number on the mower’s frame or under the seat. This battery is aftermarket, not OEM Troy-Bilt, but it’s a standard size compatible with many Troy-Bilt, Craftsman, and Husqvarna tractors with U1 trays. Measure your existing battery tray to ensure it fits—tight spaces may need a shim. Also confirm your mower’s charging system (usually 12V) will work—this battery is maintenance-free and sealed.

Key Things to Know

• Quality: Sealed AGM (absorbent glass mat) design—no water refills, spill-proof, and vibration-resistant. Good for rough terrain.
• Installation: Simple swap—disconnect negative first, then positive. Use a 10mm wrench for terminal bolts. May need terminal adapters if your cables have different connectors (common on older mowers).
• CCA: 200 CCA is sufficient for most single-cylinder lawn tractor engines (12-20 HP). Not for larger riders or zero-turns needing 300+ CCA.
• Gotcha: This is a “bare” battery—no hardware included. Reuse your old bolts or buy new ones (M6 x 1.0, 15mm length). Also, fully charge before first use if voltage is below 12.6V.

Should You Buy It

For $59.99, this is a solid, no-fuss replacement for a Troy-Bilt 361113 or any U1-compatible lawn tractor. It’s affordable, maintenance-free, and rated well for reliability. Buy it if you want a drop-in battery with good cold-cranking power for seasonal mowing, but skip it if you need higher CCA for a larger engine or want a brand-name OEM part.
