Recommended Battery
For the 2737-20, the 48-11-1850 (5.0Ah) provides the best balance of runtime and weight. Jigsaws are moderate-demand tools, so a 5.0Ah battery will last through extended cutting sessions without making the tool feel overly heavy. For lighter finish work where weight matters, a 48-11-1830 (3.0Ah) keeps things nimble.
Minimum Battery
The 48-11-1820 (2.0Ah) compact battery works well with the 2737-20 for quick cuts and short sessions. Jigsaws draw less current than circular saws or grinders, so even compact batteries can deliver reasonable runtime for occasional use.
Battery Compatibility Notes
- All M18 REDLITHIUM batteries are backwards and forwards compatible with every M18 tool
- Jigsaws are moderate-demand tools — compact batteries work better here than with high-draw tools
- M18 batteries are NOT compatible with M12 tools or older V18 tools
- Higher orbital settings increase power draw — use a larger battery if cutting thick hardwood at full orbital
