Description
Product Overview
The Mighty Max ML-U1 is a 12‑volt, 200 Cold Cranking Amps (CCA) sealed lead‑acid (SLA) battery engineered specifically for Toro Time Cutter SS4225 zero‑turn lawn mowers. Measuring 7.62 × 5.00 × 7.00 inches and weighing 12.89 lb, this compact unit fits into the standard battery compartment of most residential and commercial mowers without the need for additional brackets. The battery utilizes an AGM (Absorbent Glass Mat) technology that makes it completely spill‑proof, allowing installation in any orientation—upright, side‑mounted, or even inverted—without risk of electrolyte leakage. Its robust internal construction resists vibration and shock, which are common in high‑performance mowing environments, ensuring a long service life even under demanding conditions.
