Mighty Max Battery ML-U1 12V 200CCA Battery for Scag Tiger Cub Zero-Turn Lawn Mower

What It Is

The Mighty Max Battery ML-U1 is a 12-volt, 200 cold-cranking-amp (CCA) replacement battery designed for zero-turn mowers like the Scag Tiger Cub. It powers the starter and electrical system, suitable for mowers that require a U1-size battery.

Fitment & Compatibility

Before buying, confirm your Scag Tiger Cub uses a U1 battery group size—measure the battery tray: U1 dimensions are roughly 7.7" L x 5.1" W x 6.2" H. This is an aftermarket battery, not OEM Scag, but fits most Tiger Cub models (e.g., with Kawasaki or Kohler engines) that call for a 12V U1 battery. Check your owner’s manual or existing battery label for CCA rating—200CCA is standard for many, but verify your mower needs at least 200CCA. Also ensure terminal orientation matches (positive on right when facing terminals) and that the included hardware fits your cables.

Key Things to Know

• Quality: Mighty Max is a budget-friendly brand; 4.3 stars from 4 reviews suggests decent reliability, but it may have shorter lifespan than premium brands (e.g., Exide, Yuasa) in heavy-use or cold climates.
• Installation: Simple swap—disconnect negative first, remove old battery, install new one, reconnect positive then negative. No special tools needed, but wear gloves and safety glasses.
• Gotchas: The battery comes dry-charged with acid pack—you must fill and charge it before first use. Some users report terminal bolts may be slightly smaller than stock; check your cable clamps fit snugly.
• Maintenance: It’s a flooded lead-acid battery—check water levels every few months and top off with distilled water if needed. Not spill-proof like AGM batteries.

Should You Buy It

If you need a low-cost replacement for a Scag Tiger Cub and are comfortable with minor setup (filling acid, initial charge), this battery works well for occasional residential use. Skip it if you mow commercially, in extreme cold, or prefer a maintenance-free AGM battery—pay more for a sealed option.
