Same power, smaller package
Bosch points to the power and runtime of a first-generation product, only smaller.
With the help of greater power efficiency found in 21700 Lithium-ion cell technology, Bosch says it 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.”
What’s the secret to battery life? Bosch explains this way: “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.”
