Bosch CORE18V 12.0Ah ProFactor Battery

High-Power Bosch 12.0Ah ProFactor Battery Delivers Extended Runtime For Demanding Applications

In addition to the recently-released ProFactor tool and battery lineup, the Bosch Core18V 12.0Ah ProFactor Battery promises the most possible power and runtime on the platform. Bosch engineered this battery for exclusive use with the ProFactor cordless tool lineup. With its size and 3.04-lb weight, it stands to reason that Bosch has this battery in mind as an ideal solution for extended runtime applications.

Bosch on the 12.0Ah ProFactor Battery Pack

The 12.0 Ah ProFactor Exclusive battery was engineered specifically for our new ProFactor lineup to deliver power comparable to corded tools. Both the Core18V 8.0 Ah and 12.0 Ah ProFactor batteries are optimized to deliver the power and runtime needed to tackle tough jobs from drilling and grinding to cutting. The 12.0 Ah is the endurance workhorse for jobs that require long runtime.

Battery Features

Bosch made the 12.0Ah ProFactory Battery compatible exclusively with their tools equipped with BiTurbo Brushless motors. This means that this battery, like the other ProFactor battery lineup, won’t work with standard 18V Bosch Tools. While this seems limiting, the benefits of having a bespoke battery could outweigh its limitations.

The ProFactor tools paired with the ProFactor batteries deliver the same power with the added benefit of at least 50% more runtime when compared to the CORE18V 8.0Ah pack. This stands to reason, considering this pack sports ~50% more capacity.

The ProFactor advanced battery cell technology, advanced pack design, and CoolPack 2.0 technology come together to extend the battery life. Compared to non-CoolPack batteries, the Bosch 12.0Ah ProFactor BAttery cools 15% faster and provides a 135% longer lifespan.

This pack uses 21700 cells, as well as copper end plates, power rails, and a flexible circuit board to reduce resistance and increase the efficiency of power transfer from the pack to the tool.

Final Thoughts and Pricing

Clearly, this battery benefits power users on Bosch’s most advanced ProFactor cordless tools. You can pick up the Bosch Core18V 12.0Ah ProFactor Battery Pack for $199. It comes with a limited 1-year warranty, though that can be extended to 2 years with the Bosch ProVantage program. Hopefully, we’ll also see it included on some kits.
