Who the Deta DB442 is for
The Deta DB442 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 44 Ah battery, the DB442 is a direct replacement.
At 44 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The DB442 belongs to the Deta DETA Power range. See all Deta batteries
