Older vehicles with modest electrical demands place specific requirements on a battery: reliable cold-start performance, low self-discharge, and straightforward fitment without the complexity of advanced charge management. The Bosch S3003 is a 12V, 45Ah standard flooded lead-acid battery rated at 400 CCA (EN), engineered to meet those demands as an economical, dependable replacement for a wide range of conventional petrol and diesel vehicles.
Manufactured using Bosch PowerFrame? grid technology, the S3003 features a stamped, expanded metal grid that delivers improved current flow, reduced internal resistance, and greater resistance to corrosion and vibration compared to conventional cast-grid designs. The labyrinth lid recirculates electrolyte vapour back into the cell, supporting the 100% maintenance-free operation that requires no topping-up under normal service conditions. Robust carry handles are integrated into the case to aid safe handling during installation.
The battery measures 207mm (L) × 175mm (W) × 190mm (H inc. terminal) and fits BCI/DIN case group equivalent to Type 077. Terminal placement is Position 1 (positive terminal right), with a B13 hold-down base. It carries the cross-reference 077 and is suitable for conventional vehicles only – it is not compatible with start-stop, EFB, or AGM applications. Weight is 11.57 kg.
The S3003 is one of eight variants in the Bosch S3 range, which spans a broad spread of capacities and fitments. Related S3 variants include the S3000, S3001, S3002, S3004, S3005, S3006, S3016, and S3017.
This battery is covered by a 3-year warranty against manufacturing defects, providing assured service life under everyday driving conditions.
