The easiest way is to use the data of your old battery. Make a note of the capacity, voltage, base strip and circuit. For 100% accuracy you should measure the size (length, width and height) of the old starter battery. With this data you can easily find the right starter battery.
You don't know what to do? Then send us pictures of all sides of the old battery. We will be happy to you find the right starter battery.
● Acid: Inside the battery is liquid acid which should be refilled at regular intervals - this is usually the cheapest price variant. Most of our autmotive batteries are sealed maintenance free
● AGM (Absorbent Glass Mat Technology): In AGM batteries, the electrolyte (acid) is completely bound in a glass fibre fleece, so the batteries are leak proof - medium price variant.
● GEL: The acid in these batteries is thickened to a gel. Like the AGM battery, they are leak proof and extremely durable - high-quality price variant.
