Bosch GBA18V40 CORE18V 4.0 Ah Battery Offers Power and Runtime of First-Generation Product in Smaller, Lighter Package

21700 Lithium-ion cell technology delivers the right power solution for heavy-duty cordless power tool applications

Mt. Prospect, Ill., July 17, 2018 – The only thing that can make increased battery power more attractive is putting all that additional performance in a smaller package. With the help of greater power efficiency found in 21700 Lithium-ion cell technology, Bosch has developed the GBA18V40 CORE18V 4.0 Ah battery to bring all of the capability of the original CORE battery into a smaller, lighter package. The new cell introduces much more active battery volume in a pack that’s only slightly larger than the previous 20700 cell packs.

The Bosch CORE18V40 4 Ah battery is designed to make day-to-day work easier, particularly repetitive applications and overhead tasks. The Bosch design allows the power cells to be arranged in a single layer, which adds to a smaller and lighter battery.

“For the construction professional out on the hot jobsite or the remodeler working in the cramped spaces of a 100-year-old house, there are concerns about efficiency and fatigue,” said Theron Sherrod, product manager, Bosch Power Tools. “Keep the power, lose the weight” is a meaningful phrase to our users after a day spent drilling holes or driving fasteners. This is the value of the Bosch CORE18V 4.0 Ah battery to the professional.”

Advanced Technology Cooling

Bosch CoolPack 2.0 technology advances the lifetime of the battery as well, delivering up to 135 percent longer life versus conventional batteries without CoolPack. Heat is the enemy of any battery and this design ensures heat dissipation is maximized thanks to a housing that completely encases each cell. The high-density polyethylene material and the proprietary design combine to pull heat away from the cells for better dissipation. In addition, the battery is designed without space gaps, which ensures any heat produced by the cells is not stored in the interior. Optimized cell connectors made of copper versus copper-coated galvanized steel offer lower resistance for increased power output over a longer period of time.

Bosch CORE18V batteries provide 100 percent compatibility with all 18-volt Bosch Lithium-ion tools and chargers. Bosch is developing high-power tools to take full advantage of CORE battery technology.
