Bosch EXPERT EXBA18V-80 18V 8Ah High Power Tabless Battery
The Bosch EXPERT EXBA18V-80 is Bosch's flagship 8Ah 18V battery, built around pioneering dual-layer tabless cell technology. Unlike conventional batteries that use only two tabs as current paths, tabless cells use countless current paths — dramatically reducing internal resistance, minimising heat generation, and unlocking maximum power delivery. The result is up to 120% more runtime and up to 2400W of instantaneous maximum power versus the Bosch GBA 18V 4.0Ah.
Key Features
- Dual-Layer Tabless Cell Technology: Industry-leading cell design reduces inner resistance for maximum power output up to 2400W and cooler, more efficient operation
- Ultra-Fast Charging: Fully charged in just 39 minutes using the EXAL18V2-320 or EXAL18V-160 EXPERT charger
- COOLPACK 2.0 Technology: Bosch-exclusive active thermal management cools the battery faster and helps provide longer service life versus non-COOLPACK batteries
- 120% More Runtime: Significantly outlasts the Professional GBA 18V 4.0Ah in real-world heavy-duty applications such as grinding
- 5-LED Indicator with Haptic Feedback: Displays state of charge, remaining capacity, and defect risk — button activates with tactile confirmation
- FlexTemp Charging: Extended charging temperature range from -10°C to +55°C battery temperature with EXPERT chargers, enabling fast charging of warm or cold batteries
- Industrial-Grade Build: Reinforced housing, TPE overmold grip, redesigned battery release button, and central recess for rapid single-hand battery swaps
- Universal Compatibility: Fits all Bosch Professional 18V tools (compatible since 2008) and the AMPShare multi-brand battery alliance
Applications
Purpose-built for high-draw tools including angle grinders, circular saws, rotary hammers, and mitre saws. The 8Ah capacity and tabless cell design make this the go-to choice for sustained heavy-duty use on busy fabrication and construction sites.
