💡 Pro Tip
Designate one older or lower-capacity M12 or M18 battery specifically for USB charging duty. As batteries age and lose peak tool performance, they still retain plenty of capacity for USB charging — which draws far less current than a power tool. This extends the useful life of aging packs and keeps your high-capacity batteries reserved for tools. Label it with tape so it doesn't accidentally end up in a tool mid-job.
