Check tool and charger compatibility

The existing listing identifies selected M18 drills, drivers, saws and other cordless tools. Match your original battery number, tool manual and physical connection before ordering. M18 compatibility is model-specific, not a guarantee for every tool or charger in the range.

• Battery references to compare: M18, M18B, 48-11-1811, 48-11-1815, 48-11-1820, 48-11-1822, 48-11-1828, 48-11-1840, 48-11-1841, 48-11-1850 and 48-11-1852.
• Tool examples from the existing listing: 2606-20, 2607-20, 2704-20, 2729-20 and 2787-22. Check the exact model and battery connection on your tool.
• Original chargers: before using an M18 charger, confirm its manual supports the battery chemistry and that the pack seats correctly. Compatibility with specific charger models or fault-free charging has not been verified for this pack.

Capacity for demanding work

At the same 18V, a 6.0Ah pack has 50% more rated capacity than a 4.0Ah pack and three times the rated capacity of a 2.0Ah pack. Actual runtime and performance depend on the tool, load, battery condition and temperature. For high-draw equipment such as grinders or circular saws, confirm fit and operating requirements with the tool manual; sustained high-current performance has not been independently verified for every M18 model.

Technsave offers this Auckland-dispatched, third-party 18V 6.0Ah battery for compatible Milwaukee M18 tools. Compare your existing battery and tool model before ordering.

Can this battery power high-draw M18 FUEL tools such as grinders and circular saws?

It is sold as an M18-compatible 18V 6.0Ah replacement pack, but suitability for a particular high-draw tool depends on that tool's requirements and the battery's actual discharge capability. Check the tool manual and battery fitting; sustained high-current performance has not been verified for every M18 FUEL model.
