Powerful Lightweight Dry-Cell Batteries

Davis Unified Ignition (D.U.I.) Dyna-Batt Batteries produce more power per pound than any battery on the market, and weigh at an astonishing 13.5 lbs.! These batteries offer extremely low internal resistance which allows faster, more consistent starting and a reserve capacity of 16 Amp Hours. The Dyna-Batt is a complete dry cell and can withstand the rigors of high-performance and racing environments. Built with corrosion-resistant terminals and is truly maintenance free. The Dyna-Batt does not have a cold cranking amp rating like other batteries but has been tested to crank engines with compression ratios as high as 15:1.
