Use the Redtop high-performance AGM Spiral cell Battery, Group Size 78, to restart and restart your vehicle. For a dependable start-up and extraordinary resistance to the most frequent reasons of battery failure, it produces a powerful burst of ignition power. Two pure (99.99%) lead plates coated precisely in lead oxide form the basis of a sequence of individual spiral-wound cells, which make up the core of the Optima Spiral cell Technology. This innovation in battery design outperforms traditional flat-plate batteries on a consistent basis while delivering more power. Unlike flooded batteries, sealed Absorbed Glass Mat (AGM) batteries from Optima Batteries do not leak, sulfate, or deteriorate over time. As a result, both when discharging and recharging, efficiency is increased.
