The AMPShare battery system

Stronger. Simpler. More versatile.

Greater mobility and flexibility on the construction site are among the unbeatable advantages of the AMPShare battery system. It no longer matters whether power is available on site, you can get started straight away. In addition to time, tradespeople save money. AMPShare offers a simple and cost-effective way to build up a sustainable stock of 18V tools. The longevity of the AMPShare batteries is a key factor in this. The outstanding Coolpack technology ensures rapid heat dissipation, which enables the exceptionally long battery runtimes and extends their service life.

AMPShare is a cross-brand battery system that gives you the flexibility to operate professional tools from different brands with one and the same battery. The AMPShare batteries, which are available in different sizes and power capacities, make it possible to use different tools from all AMPShare partner brands with the same battery - including the entire Bosch Professional 18V system.

AMPShare is made up of the terms "AMP", short for ampere (unit of measurement for electrical current), for the performance of the system, and the term "Share", which stands for the sharing of the battery on a universal battery platform and emphasises the idea of sustainability.

As a compact and lightweight battery pack, AMPShare offers mobility and unlimited flexibility for more ergonomic and comfortable working. Even without an external power source, the machines can be operated in different locations without restrictions. Work processes are optimised and accelerated for an ideal result in the shortest possible time.

The AMPShare platform currently includes more than 300 tools from 33 brands. The AMPShare battery technology is based on the Professional 18V system from Bosch Professional. This means that more than 80 million rechargeable batteries have already been sold on the market and can be used with all AMPShare tools.
