ML-U1-CCA -12 Volt, 200 CCA, Nut and Bolt (NB) Terminal, Rechargeable SLA AGM Battery


ML-U1-CCA -12 Volt, 200 CCA, Nut and Bolt (NB) Terminal, Rechargeable SLA AGM Battery

The ML-U1-CCA is a 12-volt, 200 Cold Cranking Amp (CCA) battery built with Sealed Lead Acid (SLA) technology in an Absorbent Glass Mat (AGM) design. This combination means it’s a reliable, maintenance-free power source for a wide range of applications where dependable starting power or consistent energy is needed.

Let’s break down what those technical terms mean for you. The 12-volt rating is the standard for many vehicles and equipment.

The 200 CCA is a crucial spec; it tells you how much power the battery can deliver to start an engine in cold weather. This makes the ML-U1 a strong candidate for smaller gasoline engines, like those in motorcycles, ATVs, riding mowers, or compact utility vehicles. It’s not meant for large car or truck engines, but for its intended size, it provides solid cranking power to get you going.

The SLA AGM construction is a significant feature.

AGM stands for Absorbent Glass Mat, where the electrolyte is suspended in a fiberglass mesh. This makes the battery completely sealed, so you never have to add water. It can be mounted in most orientations without risk of leakage, which offers more flexibility during installation. The sealed design also minimizes gas emission and is generally more resistant to vibration compared to traditional flooded batteries.
