They're built to drop right into the Bosch BAT609 / BAT610 / BAT611 / BAT612 / BAT614 and BAT618 family of 14.4V and 18V cordless tools, so you get a dependable fix without the brand-name price tag.

Pick the Right Pack for Your Tool

Each option is matched to a specific Bosch model and voltage, so just check the sticker on your existing battery and grab the matching one below.

Built to Last, Built to Protect

• Clean, consistent power: premium lithium cells hold voltage steady while you drill, so your tool keeps full torque longer.
• Safety packed in: built-in overcharge, over-discharge, over-current and short-circuit protection look after both the pack and the tool.
• Easy charge status: LED indicators show remaining charge at a glance.
• Solid build: reinforced housing fits snugly and locks in place, no rattling mid-cut.

Made for Everyday Workshops

Whether you're driving screws on a deck, cutting tile, or running an impact wrench on a jobsite, these packs handle steady, repeated use. The 14.4V options suit lighter drills and drivers, while the 18V packs bring extra grunt for heavier work like circular saws and angle grinders.

• BAT609, BAT610, BAT611, BAT612, BAT614, BAT618

Standard dimensions and terminal layout mirror the Bosch pack design, so it clicks in and charges on your existing charger.

Common Questions

Will this fit my Bosch drill? If your tool takes a BAT614, BAT618, BAT609, BAT610, BAT611 or BAT612-style battery, it fits. Match the voltage on your current pack to be sure.

Can I use my existing Bosch charger? Yes. These packs use the standard Bosch terminal layout and charge fine on a compatible 14.4V or 18V charger.

How long will it last per charge? That depends on the capacity you pick and how hard the tool works — higher mAh options run longest between charges.

Pair It With the Right Accessories

Keep a spare on the go and stay fully charged with a compatible 14.4V-18V fast charger, or run your Bosch gear from the truck with a portable multi-voltage inverter.
