Why This Tool Is Worth It

A high capacity battery is what lets your cordless tools perform at their best. This 8Ah pack uses high power tabless cell technology, which lowers internal resistance so the battery runs cooler, delivers more power, and lasts longer between charges.

Compared to the Bosch CORE18V 4Ah battery, it delivers up to 140% more instantaneous maximum power and up to 120% longer runtime. That makes a big difference on demanding tools like circular saws, miter saws, routers, and grinders. Bosch exclusive COOLPACK technology helps extend battery life, and with a compatible fast charger in Power Boost mode, it can fully charge in just 39 minutes. Add a free tool to the deal, and this is a smart way to grow your Bosch lineup.

Features

• High power tabless cell technology provides lower internal resistance for reduced battery heating, increased power, longer runtime, and optimized performance

• Delivers up to 140% more instantaneous maximum power and up to 120% longer runtime than the CORE18V 4Ah battery (GBA18V40)

• Bosch exclusive COOLPACK technology cools the battery and helps provide a longer lifetime compared to non COOLPACK Bosch 18V batteries

• Battery status indicator light with haptic feedback button provides quick and clear battery status updates

• Redesigned battery release button for quick and easy battery installation and removal

• Industrial grade design with TPE grip and central recess for easier handling and faster battery swaps

• Compatible with Bosch 18V tools and chargers

• The GAL18V160 charger can fully charge the EXBA18V80 8Ah battery in just 39 minutes in Power Boost mode

• Active air cooling uses two fans to cool the battery, optimizing charging time while protecting batteries from overheating

Who This Is Best For

This battery is ideal for woodworkers, contractors, and DIYers who are already using Bosch 18V tools. It belongs in garage shops, full size workshops, and jobsite setups where high demand cordless tools need extra power and runtime. If you're constantly swapping out smaller batteries, an 8Ah pack will keep you working longer between charges.
