(1) AGM (Absorbent Glass Mat): acid bound in micro glass fibre mat allows higher energy masses to pass through
(2) Special grid design: patented stamping process for optimized current flow, less corrosion and long service life
(3) EFB (Enhanced Flooded Battery): positive plate coated with polyester scrim provides additional support for the active material and high cycle stability
(4) Labyrinth cap: returns condensed water to the battery, integrated central degassing, backfire protection and additional sealing ring for high operational safety

Tips for testing and storing batteries

Mechanic tests S5A battery with BAT 115

Check batteries

  • Measure voltage with voltmeter (e.g. Bosch BAT 131 / BAT 115)
  • Charge at a voltage below 12.4 V
  • Avoid deep discharge (prevents sulphation and damage)
  • Below 10.5 V = defect, replace battery
  • Only carry out a standard battery test after at least 4 hours of rest after charging
Bosch car batteries SLI (S4 008,S4 E08, S5 A08)

Storing batteries

Store batteries in a dry, cool place (approx. 15 °C) and out of direct sunlight. High temperatures accelerate self-discharge and ageing.

To do:

  • Check voltage every 2 months
  • Charge with OCV below 12.4 V
  • Observe "First in – First out" during storage
