100 years of Bosch batteries

In the early 20th century, Bosch was already developing automotive technologies. For 100 years now, Bosch batteries have been a reliable source of energy.

Back in 1922, Bosch started producing motorcycle batteries. In 1927, the first Bosch car batteries were launched. Ever since and up to the present day, Bosch has continuously expanded its range adjusting it to changing market requirements and new technological possibilities.

As of the 1960s, for instance, car batteries were equipped with plastic housings and state-of-charge indicators. High performance cold-start batteries for diesel vehicles and thin-plate batteries soon complemented the range.

As of 1970, batteries were equipped with diagnostic plugs for checkups. In 1983, the use of calcium-based alloys for the battery grids resulted in the first maintenance free starter batteries for cars. In the early 2000s, powerful AGM (Absorbent Glass Mat) batteries were launched for vehicles equipped with start/stop systems.

In 2016, the Bosch lithiumion motorcycle battery was granted the Automechanika Innovation Award in the Parts & Components category. Since 2019, Bosch also offers commercial-vehicle AGM batteries.

No matter whether cars, trucks, hybrids or vehicles with conventional powertrains, modern motor vehicles are equipped with more and more comfort and convenience functions running on electric energy. Reliable sources of energy with high performance are thus needed to supply them.

Equipped with modern technologies, Bosch batteries reliably supply many different types of vehicles with the energy they need and over extended periods of time. This is particularly true for the powerful Bosch AGM or EFB batteries.

At AGM batteries, the battery acid is absorbed by microfibre glass mats. This increases the battery service life and its deep-cycle resistance – a clear advantage for the consistent performance of start/stop systems and in case of high consumption during standstill.

Enhanced flooded batteries (EFB) are particularly deep-cycle-resistant. Both types of batteries feature an outstanding charge acceptance and a particularly high cold starting performance.

Since 2019, Bosch also develops and produces 48- volt batteries for the original-equipment service of mild hybrid vehicles.

Bosch will be exhibiting at this year’s Auto Trade EXPO, which takes place from Saturday and Sunday, October 15-16 at the RDS Simmonscourt in Dublin.
