Quick answer: Built for cars and vans, the Optima RTS-2.1 carries the rating 50Ah 6V 815A. Owners usually check three things first: size, terminal side and starting power.

Using it day to day: practical tips

Holiday over, the car has sat at the airport for two weeks and the dashboard barely lights up. Drive for at least twenty minutes after fitting to let the battery settle in. Jump-starting the car every few days is a clear message that the battery needs replacing.
