MAJOR CAR BATTERY BRANDS RANKED WORST TO BEST

7. Deka

Deka’s lineup runs from basic to top-tier, with their Intimidator series at the high end. Those use AGM tech and include options for hybrids and EVs, which still need a regular 12V battery for electronics like lights and the radio.

The lower-end Standard, Gold, and Ultimate batteries vary in power and price, with Gold and Ultimate offering better performance. Reviews are strong across major retailers, especially for the Intimidator and Gold lines. The main complaints? A few bad units out of the box—but most are covered by warranty. Still, it knocks them down a peg or two.
