OPTIMA® REDTOP® batteries stand ready and waiting to serve. Delivering immense power to the starter in the initial starting phase, REDTOP batteries feature patented SPIRALCELL TECHNOLOGY® and are ideal for applications where starting power is the priority. Commercial agricultural equipment and construction equipment are two markets where OPTIMA REDTOP batteries have become very popular. Of course, they perform great in emergency vehicles, generators and street cars as well. The REDTOP’s extremely low self-discharge rate means you can leave it untouched for extensive periods of time, and it’ll still start your engine. And that can enhance productivity by reducing maintenance times and engine repair costs.
