Bosch Batteries – S3, S4, S4 EFB, S5 and S5 AGM 

Bosch S3, S4 and S5 Batteries

We use Bosch batteries

Bosch Batteries Supplied & Fitted

Where possible we use Bosch batteries when renewing or repairing a vehicle. We use the latest Bosch testing equipment to confirm whether a battery is good or bad and then replace with the relevant Bosch battery.

With modern vehicles becoming more reliant on solid, steady power, your battery is a critical component to ensure the car starts reliably and can handle the power requirements needed.

Bosch offer a complete range of batteries to suit virtually every vechicle so please do get in touch if you need to know more. Remember there are specialist batteries made for high power usage vehicles or those which employ start/stop technology. 

There is a Bosch battery for virtually every occasion

S3, S4 & S5 PowerFrame

Bosch S3, S4 & S5 Battery Family

With its S5, S4 and S3 batteries, Bosch offers three made-to-measure battery lines for a great variety of requirements and vehicle types.

The grid with special PowerFrame ® technology – responsible for optimum electricity flow, lower corrosion and a longer service life – is crucial for the performance and reliability of these Bosch batteries.

The S5, S4 and S3 therefore satisfy the stringent international quality requirements for cold starting performance and capacity.

S3, S4, S5 Advantages

  • 100 % maintenance-free
  • Maximum reliability
  • thanks to double backfire protection, which protects the battery from sparks even during transport and when tilted
  • Sealed battery cover prevents leakage of electrolyte
  • First-class quality from Bosch
  • Ergonomic handles for simple installation and easy transport

S4 EFB For Start/Stop Systems

Bosch S4 EFB Start Stop Battiers

The S4 EFB (Enhanced Flooded Battery) technology satisfies all requirements that lie somewhere between conventional starter batteries and the S5 AGM.

The S4 EFB is designed for vehicles with start/stop system. Its deep cycle resistance ensures that sufficient energy is available at all times for restarting the vehicle. Even when a large number of energy consumers are in operation in the vehicle during the stop phase, it maintains its excellent starting performance.

S4 Advantages

  • Longer service life and double the deep cycle resistance of conventional starter batteries
  • More reliable starting even in extreme temperatures and with a large number of electrical devices
  • Outstanding charge acceptance and good resistance to short-haul operations
  • With additional polyester scrim between plate and separator
  • Leak-proof and tilt-resistant up to 55°
  • First-class quality from Bosch
  • Absolutely maintenance-free

S5 For Start/Stop Systems

Bosch S5 Start Stop Batteries

The constantly growing amount of electric consumers in modern vehicles and special requirements such as start/stop systems and braking-energy recuperation call for top-performance batteries. The Bosch S5 AGM battery delivers the power for frequent starts and stops, and reliably supplies electronic devices during the stop phase.

AGM (Absorbent Glass Mat) technology from Bosch is the leading technology on the market for the most exacting requirements. Special mats of very thin glass fibers hold all the electrolyte, allowing higher amounts of energy to pass through. This enables the Bosch S5 AGM battery to give a top performance.

S5 Advantages

  • Longer service life and up to 4 times greater deep cycle resistance than conventional starter batteries
  • Constant power even on short trips, in stop-and-go traffic or high consumption when stationary
  • Excellent charge acceptance and starting performance with a large number of electrical devices
  • Absolutely maintenance-free
  • Leak-proof and suitable for installation in any position
  • First-class quality from Bosch
