Bosch CORE18V 5.5 Ah Performance Battery (GBA18V55)

High-output performance pack. Perfect power-to-weight sweet spot for continuous deep cuts in 3-in. thick timbers and metal beams.

Cell Engineering & Performance

Engineered for high-draw brushless tools. Provides higher peak wattage than standard 4.0 Ah batteries while retaining manageable bulk on the base of heavy-duty jigsaws like the JS572EBL.

Workshop recommendation: Great middle ground for production woodworkers wanting more juice than 4.0 Ah without the bulk of a 12.0 Ah monster pack.

Key Features

  • 5.5 Ah high-output 21700 cell array delivers up to 1,800W corded equivalent power
  • CoolPack 2.0 active thermal management avoids heat throttling
  • High-contrast 5-LED fuel level indicator

Before You Buy

Ensure you possess a compatible rapid charger from the same manufacturer and platform (or purchase an official Starter Kit bundled with a charger). Lithium-ion packs should not be stored completely depleted; maintain approximately 40% to 60% charge if storing for extended workshop downtime.

When browsing merchant listings on Amazon, verify whether the listing designates a single bare battery pack, a multi-pack, or a complete kit with high-speed charging dock.
