Bosch CORE18V 4.0 Ah Compact Battery (GBA18V40)
Single-layer compact powerhouse. Provides the output of standard 4.0 Ah two-row packs in a substantially lighter footprint for nimble jigsaw curve maneuvering.
Cell Engineering & Performance
The Bosch CORE18V 4.0 Ah (marketed globally as ProCORE18V) is the recommended battery for Bosch cordless jigsaws. Its single-layer 21700 cell architecture lowers the center of gravity at the base of the saw while delivering uninterrupted current through dense hardwoods. The CoolPack 2.0 outer shell directs heat away from interior cells, preventing thermal shutdowns during heavy cuts.
Workshop recommendation: The most balanced battery for top-handle and barrel-grip jigsaws: does not add excessive bottom heft on vertical or overhead scribing cuts while easily lasting full work shifts.

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.
