Who the Kronobat SD-91.1T is for
The Kronobat SD-91.1T is a starter battery for cars without Start-Stop: it delivers the current the starter motor needs and then powers lights, control units and audio with the engine off. If your car has no Start-Stop and had a 91 Ah battery, the SD-91.1T is a direct replacement.
At 91 Ah it moves into large diesels, SUVs, vans and cars with heavy electrical equipment. The SD-91.1T belongs to the Kronobat STANDARD range. The full range of Kronobat batteries
