Batteries

Reliability and profitability along the way

As batteries have to cope with increasing strains, according to several statistics, they are one of the key reasons for breakdowns. Good to know, you can fully rely on Bosch commercial-vehicle batteries. They are powerful, vibration-resistant and even maintenance-free. This will cut the fleet operating costs.

Brochure

Performance: Even in case of stationary operation, the batteries power a wealth of safety and convenience features. And yet they are able to cope with frequent charge and discharge cycles.
Economy: Low maintenance efforts help reducing the fleet operating costs.
Robustness and resistance: Due to harsh environments high robustness and vibration resistance are required.

Patented PowerFrame^® (grid) for optimized current flow and reduced corrosion
The special grid-stamping technique makes this battery particularly corrosion-resistant and durable. The flow-optimized PowerFrame^® grid design ensures consistently high starting power. This results in a very low self-discharge rate.

Labyrinth lid
The double lid with labyrinth design returns condensed water to the battery. As a result, T5 batteries are absolutely maintenance-free and leakproof. They consume very little water. The integrated central degassing, backfire protection and an additional sealing ring ensure high operational safety.

Ion-permeable pocket separator
Prevents any contact between positive and negative plates – thus increasing both service life and starting power.

Additional stabilization for vibration resistance in line with V4 standard	EFB (Enhanced Flooded Battery)
Mixing elements	EFB (Enhanced Flooded Battery) Improve electrolyte mixing and prevent acid layering – thus expanding the ser- vice life and improving the deep-cycle resistance.
EFB (Enhanced Flooded Battery) technology	EFB (Enhanced Flooded Battery) At EFB (Enhanced Flooded Battery) technology, the positive plate is coated with a polyester scrim (fleece). It ensures additional retention of the active material on the battery plates doubling the deep-cycle resistance in comparison with conventional batteries. The specially glued polyester fleece reliably keeps the battery plates in position. As a consequence, the battery remains operational even if subject to strong and lasting vibrations.
