Small Case Lithium Battery

The AG-1201 battery has 360 Cranking Amps yet is only 4.50″ Length x 3.25″ Depth and 4.25″ Height (to the top of the terminals). This battery is a great choice for those seeking very high power in a compact battery. It can replace the typical 12 Ah lead/acid battery with a weight savings of up to 7 pounds while offering much more cranking power. This battery is best used for applications where extreme weight loss and ultra compact size are desired.

    Battery was great till it just stopped. Warranty not honored because it was used in a jet ski. The box has a picture of a jet ski on it and they make recommendations for jet ski applications…
