Bosch Professional 18V System replacement batteries

About this battery system

Bosch Professional's blue 18V system includes standard GBA packs and ProCORE18V batteries. ProCORE packs focus on high-current output and heat management, and the platform participates in the AMPShare alliance.

Bosch Professional 18V (blue) is not the same battery system as Bosch DIY POWER FOR ALL 18V (green).

Manufacturer-supported example specifications below; individual tool fitments and Amazon availability still require checking.

Battery chemistry, cells and energy

Bosch advertises advanced cell technology and COOLPACK thermal management; the exact cell format should be checked against the specific pack rather than assumed.

Energy (Wh) = nominal voltage (V) × capacity (Ah). Divide by 1,000 for kWh. These are nominal estimates, not measured usable energy or guaranteed runtime. A 90Wh pack is 0.09kWh; at an illustrative constant 90W load, ideal runtime would be one hour before losses. Real power tools draw variable power.

Choosing a replacement battery

Platform family is an initial research grouping, not a verified fitment for every tool or generation. Check exact tool model, battery part number, connector and charger compatibility. Do not assume matching voltage means interchangeable.
