Batteries

High energy supply for mobile applications

Leisure and Off-Highway Battery Group Picture

As batteries have to cope with increasing strains, they are one of the key reasons for breakdowns. Good to know, you can fully rely on Bosch commercial-vehicle (CV) and Off-Highway (OHW) batteries.

Owners of campers, mobile homes and boats appreciate their independence and the proximity to nature. At the same time, they demand comfort and safety. Golf carts, lawn mowers and other mobile devices need large amounts of energy over a longer period of time while having to be recharged quickly. Bosch batteries are perfectly adapted to these specific requirements.

Modern mobile applications are equipped with more and more components running on electric energy. They need to be supplied by reliable sources of energy with high performance. Equipped with modern technology and featuring a corrosion-proof design, Bosch batteries provide different types of vehicles with the energy they need – over long periods.

Bosch batteries are subject to safety and resilience tests complying with legal requirement criteria and standards and monitored regularly in market applications.

Bosch batteries stand out for their high capacity, their outstanding deep-cycle resistance as well as top safety and operational reliability.

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.

Labyrinth lid	EFB (Enhanced Flooded Battery) The double lid with labyrinth design returns condensed water to the battery. As a result, TE batteries are absolutely maintenance-free and leak- proof. They consume very little water. The integrated central degassing, back-fire protection and an additional sealing ring ensure high operational safety.
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.
