Shallow discharges, a smart charger and the Rudman regs have kept the Optima YT's performance constant over the last 6 years. How much longer? We will see! New pack of 24 Optimas 55 amp hr replaced in 2004. Got rid of the troublesome Rudman regs and the Zivan programs chargers works well without the regs.
