## Quick description

## Description

## Who the Long 46B24R is for

The Long 46B24R 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 45 Ah battery, the 46B24R is a direct replacement.
At 45 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The 46B24R belongs to the Long Starting Series range. [More Long batteries](https://bateriasonline.es/en/long-batteries)
