Why This Deal Makes Sense 🔥

Batteries are the foundation of your cordless setup. More batteries mean less downtime and fewer interruptions.

With this promo, you’re getting:

Two CORE18V 4Ah batteries
A compact charger
And a FREE bare tool

That’s a serious value if you were planning to expand your lineup anyway.

The CORE18V 4Ah batteries strike a great balance between power and weight. They are lighter than larger packs but still strong enough for drilling, cutting, and grinding.

Who This Is Best For

This deal is perfect for:

Contractors already invested in Bosch 18V
DIYers building out a cordless system
Anyone wanting lightweight batteries with solid runtime
Users running standard to medium duty applications

If you’ve been swapping one battery back and forth all day, this solves that problem fast.

Features

Lightweight solution CORE18V 4 Ah battery allows you to get the power and lose the weight in a compact battery

Compact charger design gets users power ready fast with a lightweight compact solution

Power and runtime battery delivers 2x the runtime and 60% more power compared to BAT612 18V 2 Ah battery

High power lithium ion cells features a single layer of enhanced 21700 cells for greater battery efficiency

Cutting edge battery design includes copper end plates, power rails and a flexible circuit board for reduced resistance and increased efficiency

Bosch Exclusive CoolPack 2.0 technology cools the battery and helps provide longer battery lifetime compared to non CoolPack Bosch 18V batteries

Compact operation battery weighs only 1.10 lbs but provides power for standard to medium duty applications such as drilling into concrete, metal and wood, metal grinding, cutting and even light duty chipping

4 Amp charging current delivers 2x the charging current compared to the GAL18V 20 standard charger

Bosch 18V chargers are covered by a five year limited warranty and Bosch 18V batteries are covered by a three year limited warranty

Why I Like The 4Ah Size

The 4Ah packs are a sweet spot for most users. They are lighter than 8Ah batteries but still deliver plenty of runtime for drills, drivers, and saws.

Add in CoolPack 2.0 technology and faster charging, and you’ve got a battery setup that keeps up with real work.

And when you factor in a FREE bare tool up to a $229 value, this becomes a smart upgrade.
