The Bosch Expert PRO BLUE EXBA18V-80 is an 18V 8Ah lithium-ion battery pack engineered for professionals who demand maximum power and extended runtime from their cordless tools. At the core of this battery's performance is advanced tabless cell technology, which replaces the conventional two-tab current path with countless parallel current paths. This dramatically reduces internal resistance, resulting in less heat build-up, greater efficiency, and maximum power output of up to 2400W. Compared to the Professional GBA 18V 4.0Ah, this battery delivers up to 120% more runtime — a significant advantage during heavy-duty continuous work such as grinding on mild steel. Thermal management is handled by Bosch's COOLPACK 2.0 system, which works alongside the reinforced robust housing to protect the battery during demanding use. The extended charging temperature range of -10°C to +55°C adds further versatility on site, and a full charge is achievable in just 39 minutes when used with the compatible EXAL18V2-320 or EXAL18V-160 charger. A 5-LED charge indicator displays remaining capacity and provides defect risk detection, giving professionals clear visibility of battery status at a glance. The EXBA18V-80 is compatible with the full Bosch Professional 18V System and the multi-brand AMPShare battery alliance, making it a versatile choice across a wide range of cordless tools on site.
