Mighty Max Battery ML-U1 12V 200CCA Battery for Ariens SNO-Thro ST-1336 Lawn Mower

What It Is

The Mighty Max Battery ML-U1 is a 12V, 200CCA (cold cranking amps) sealed lead-acid (SLA) battery designed to power the starter motor on small engines, specifically for Ariens SNO-Thro ST-1336 snow throwers and compatible lawn mowers or tractors that use a U1 form-factor battery.

Fitment & Compatibility

Before buying, confirm your machine uses a U1 group size battery (physical dimensions: approx. 7.7" L x 5.1" W x 6.2" H). This battery is a direct replacement for Ariens SNO-Thro ST-1336 models (typically 2000-2010 era) and many other Ariens, Cub Cadet, John Deere, and Troy-Bilt riding mowers or snow throwers that require a 12V, 200CCA U1 battery. Check your owner’s manual or existing battery label for group size and terminal orientation (this battery has top posts, not side terminals). It is an aftermarket replacement, not OEM Ariens, but uses standard SAE posts. Measure your battery tray to ensure it fits—some newer models use smaller group sizes (e.g., U1R or U1L).

Key Things to Know

• Sealed & maintenance-free: No need to add water; it’s spill-proof and can be mounted in any position except upside-down.
• 200CCA is adequate: For a single-cylinder snow thrower or small lawn tractor engine (up to ~400cc), this provides reliable starting down to about 0°F. For larger engines or extreme cold, consider a higher CCA battery.
• Installation is straightforward: Disconnect negative first, swap cables (positive/negative orientation matters—check your cable length), and tighten terminal clamps. No special tools required—just a 10mm or 13mm wrench.
• Charging note: If stored off-season, use a trickle charger (1-2 amps) to avoid sulfation. Do not use a high-amp car charger—this battery is not designed for fast charging.

Should You Buy It

This battery is a solid, budget-friendly drop-in replacement for Ariens ST-1336 owners or anyone with a U1-sized machine needing a reliable 200CCA battery for seasonal use. It’s right for you if you want a maintenance-free, leak-proof option at a lower price than OEM, and you’re comfortable with basic DIY installation. Skip it if you need a higher CCA for extreme cold or a different terminal configuration (e.g., U1R).
