Lighten up your hot rod or race car by removing the heavy 40 lb battery and replacing it with Performance Distributors 13.5 lb Dyna-Batt! The Dyna-Batt produces more power per pound than any battery on the market. It has the cranking power of wet cell batteries three times its size! This is due to the extremely low internal resistance which allows faster, more consistent starting. 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. The reserve capacity of the Dyna-Batt is 16 Amp Hours. The Dyna-Batt is completely dry cell and can withstand the rigors of high performance and racing environments. It is built with corrosion resistant terminals and is truly maintenance free. The Dyna Batt has an excellent storage life and recharges very quickly. Any 12 volt charger can be used to recharge the Dyna-Batt but a low amperage battery charger/maintainer, much like the charger/maintainer we sell listed below, is recommended to avoid overcharging the battery. This battery works great with one of our alternators!
