Bosch Professional 18V system battery GBA 18V 5.0Ah

Bosch Professional GBA 18V 5.0Ah Battery — CoolPack, LED Fuel Gauge

The 5.0Ah is the workhorse of the Bosch Professional 18V battery range — and with good reason. 90Wh of energy capacity delivers extended runtimes across the entire 18V system: drills, circular saws, jigsaws, reciprocating saws, angle grinders, and garden tools. CoolPack thermal management keeps internal temperature in check during high-load use, protecting both the battery and your tool investment.

Why the 5.0Ah Is the Right Choice

• More runtime than the 3.0Ah — approximately 67% more energy; fewer interruptions on site for demanding applications like circular sawing and grinding
• CoolPack protection — dissipates heat up to 35% more effectively than standard batteries; battery and tool both last longer
• LED fuel gauge — 4-bar charge level indicator; check remaining charge at a glance without fitting the battery in a tool
• Broad compatibility — works with 100+ Bosch Professional 18V tools and AMPShare cross-brand partner tools
