Varta Batteries have a long and solid history of providing needed cranking power to a variety of different types of engine. Backed by Johnson Controls, they are at the forefront of battery technology, and with good reason: the products they produce work, and work well. It's part of the reason that they are OEM batteries for names like Massey-Ferguson, BMW, and Caterpillar, Volvo, and Land Rover, just to name a few. AGM batteries are a premium battery choice. Varta is recommended by Optima brand batteries when satisfied Optima customers look for powersports applications, and we think that's a pretty strong testament. We're betting you agree.
