LL-1257TB AGM Racing Battery

The Lifeline Racing Batteries are valve regulated, sealed lead acid (VRSLAB) recombinant gas, 12 volt, advanced glass mat (AGM) racing batteries.

Why are they better? Lifeline Racing Batteries boast industry leading low internal resistance. The lack of resistance allows all of our batteries to discharge harder, faster, and longer without producing heat. This makes our batteries more powerful, able discharge and charge faster, and last longer than conventional batteries. Lifeline Racing batteries routinely provide 20% more power, when matched against similarly sized flooded batteries. Lifeline Racing batteries routinely provide 50% more cranking amps than similarly sized GEL CELL Batteries.

The compact size and high current capability, in conjunction with quick charging and discharging characteristics make our batteries the right choice for your racing electrical systems. Then we package our battery in a light weight, yet tough battery container that meets Military Specifications for aircraft, vibration, and won`t leak. These batteries are even UL listed and the MSDS says they will not start fires. The Lifeline Racing Battery electrical characteristics, and superior battery construction make them the Best battery choice among top racers and racing teams using 12 volt systems.

The Lifeline LL-1257TB AGM Racing Battery is specifically designed for the rigorous cranking demands of the racing industry.

All Lifeline Racing batteries are hand-made in the USA. These batteries are built using the same high standards and proprietary methods that are employed in the manufacturing of similar aircraft batteries for the US Military. They are designed to deliver ample cranking power when it is needed most and are perhaps best known as industry leaders in reliability and customer satisfaction. Lifeline cranking ratings are provided using the Battery Counsel International requirements which dictate each test run for a 30-second duration.
