Bosch S4E42 Car Battery 85Ah 800A - EFB Tech for Start/Stop Vehicles

The Bosch S4E42 delivers reliable power for modern cars equipped with start/stop systems. With an 85Ah capacity and 800A cold-cranking current, it provides strong, consistent starting power even in extreme temperatures. Its patented PowerFrame grid ensures optimal current flow, so the engine turns over quickly and smoothly every time. EFB (Enhanced Flooded Battery) technology adds a polyester-coated positive plate, giving the battery triple deep-cycle resistance and lower self-discharge, which translates into a longer service life compared to conventional starter batteries. The optimized active material improves charge acceptance, meaning the battery recovers quickly after each stop and start cycle. Designed as a completely maintenance-free unit, the double-lid labyrinth reduces water loss, so you never need to top up the electrolyte. Choose the Bosch S4E42 for dependable performance, reduced maintenance, and a battery that stands up to the demands of today's fuel-efficient vehicles.
