Mighty Max Battery ML-U1 200CCA Battery for Toro Time Cutter SS4260 Zero-Turn Lawn Mower

What It Is

The Mighty Max Battery ML-U1 is a 200 cold-cranking-amp (CCA) replacement battery designed for zero-turn mowers, specifically the Toro Time Cutter SS4260. It powers the starter and electrical system on mowers requiring a U1-sized 12V battery.

Fitment & Compatibility

Before buying, confirm three things:

• Model: Fits Toro Time Cutter SS4260 (and many other zero-turns with U1 battery trays). Cross-check your mower’s OEM part number (Toro often uses a 121-9042 or similar).
• Dimensions: U1 case size – roughly 7.7" L x 5.1" W x 6.2" H. Measure your existing battery tray to ensure it’s not too tight.
• Terminal layout: This battery has left positive/right negative (standard U1). Verify your cables reach without stretching.
• CCA rating: 200 CCA is typical for small engines (18-24 HP). If your mower has a larger engine or cold winters, consider a higher CCA (e.g., 230-275) for reliable starts.

This is a sealed AGM (absorbent glass mat) battery – no maintenance or acid refills needed. It’s aftermarket, not OEM Toro.

Key Things to Know

• Quality concerns: 3.9 stars from 14 reviews is mediocre. Some users report shorter lifespan (1-2 seasons) compared to quality brands like Yuasa or Interstate. Check return policy.
• Installation: Simple – remove old battery (disconnect negative first), clean terminals, install new one (connect positive first). AGM batteries arrive fully charged, but a top-off with a compatible charger is recommended if stored.
• Cold weather: 200 CCA is adequate for moderate climates. In sub-freezing temps, a higher CCA battery may be needed to avoid slow cranking.
• Warranty: Typically 1-year limited. Verify before purchase – some retailers offer longer.

Should You Buy It

Buy this if you need a budget-friendly, drop-in replacement for your Toro SS4260 and don’t mind replacing it every 2-3 seasons. Skip it if you want maximum reliability or live in a cold climate – spend a bit more on a higher-CCA battery from a known brand (e.g., Yuasa YB14L-A2 or Deka).
