Maximize Your Cordless Runtime with Advanced Tabless Cell Technology

The Bosch EXBA18V-40 EXPERT 18V 4.0Ah Battery Pack delivers high-performance cordless power for demanding industrial and construction applications. This lithium-ion power source utilizes advanced single-layer tabless cell technology to reduce internal electrical resistance, generating up to 2X more peak power and 35% longer runtime than previous generation CORE18V 4.0Ah batteries. Engineered for rigorous site use, it features a CoolPack 2.0 heat management system that accelerates cooling to significantly extend overall battery service life. The lightweight housing incorporates improved ergonomics, an optimized release button, a thermoplastic elastomer (TPE) grip, and a highly visible haptic-feedback charge indicator gauge.

Best Used For:

  • Heavy-Duty Drilling and Fastening: Sustaining continuous torque in high-load concrete rotary hammers, impact wrenches, and drill drivers.
  • Metal Fabrication Cutting: Powering high-draw brushless angle grinders and circular saws during long grinding or ripping intervals.
  • Multi-Brand Ecosystem Integration: Operating across a growing list of cross-compatible cordless trade equipment via the AMPShare battery system.

Key Performance & Safety Features

  • High-Power Tabless Technology: Advanced single-layer tabless cell construction minimizes internal resistance, reducing heat generation while maximizing instant power output and operational efficiency.
  • CoolPack 2.0 Heat Management: Exclusive heat-conductive housing channels thermal energy away from inner cells faster, extending overall battery lifespan compared to standard non-CoolPack batteries.
  • Haptic Fuel Gauge Indicator: High-visibility onboard state-of-charge display features a haptic feedback button to provide instant tactile verification of remaining power.
  • Enhanced Ergonomic Design: Optimized structural build incorporates protective TPE grip bumpers, a centralized body recess, and a re-engineered release latch for smooth tool transitions.
  • AMPShare System Compatibility: Seamlessly powers all Bosch 18V professional cordless tools and matches leading fast chargers including the GAL18V-40, GAL18V-160, and GAX1218V-30.

Pro-Tip: To achieve maximum efficiency and longevity from your tabless cells, match this battery pack with an active-cooling fast charger like the Bosch GAL18V-160. Charging batteries at extreme temperatures bogs down cell health; utilizing a fan-assisted cooling charger pulls residual heat out of the CoolPack housing quickly, ensuring rapid turnaround times and preserving full cycle capacity.
