Power Tool Batteries Built to Outlast the Job

A cordless tool is only as good as the battery behind it, and running low on charge mid-project is one of the most common ways a job gets pushed to tomorrow. Mach 1 Lithium builds premium replacement batteries and accessories for the platforms professionals and DIYers actually use — DeWalt, Milwaukee, Makita, and Ryobi — engineered to deliver full power from the first pull of the trigger to the last, at a fraction of what the OEM pack costs.

Every battery across this lineup runs on genuine lithium-ion cells with a protective battery management system (BMS), so voltage stays consistent under load instead of sagging halfway through a cut. That consistency matters most on high-torque tools — circular saws, grinders, rotary hammers — where a weak battery shows up immediately as reduced cutting speed or stalled RPMs.

Shop by the Platform You Already Run

If your tools are already on a specific system, staying in that ecosystem is usually the easiest and most cost-effective path. Our DeWalt battery lineup covers everything from compact 12V MAX packs for drills and drivers up through 20V/60V FlexVolt batteries built for jobsite-scale saws and grinders. If you're running Milwaukee's M18 platform, our Milwaukee battery range includes standard and high-output packs sized for everything from trim work to heavy demolition tools.

Makita's LXT platform gets the same treatment in our Makita battery collection, with capacities from 2Ah up to 6Ah depending on how long you need a tool running between charges. And for Ryobi's popular ONE+ system — a favorite for homeowners and weekend DIYers — our Ryobi battery lineup keeps a full range of everyday tools charged without the premium price tag of buying direct from the brand.

More Than Just Batteries

A battery pack is only half the equation once you're actually working. Our DeWalt 20V Battery Power Inverter turns a charged DeWalt battery into a portable 110V AC power source — genuinely useful on job sites without outlets, or as backup power during an outage. For flexibility across ecosystems, our DeWalt 20V/18V Battery Adapter lets older or cross-brand tools run on newer battery packs, so you're not stuck maintaining two separate battery inventories for tools that could otherwise share one.

Beyond individual products, our broader Adapters and Inverters collections round out the ways to get more use out of the batteries you already own, whether that's bridging between tool brands or turning stored battery power into something you can plug a device into directly.

Keep the Job Site Running After Dark

Not every project wraps up before the light fades. Our Work Lights collection includes battery-powered lighting built to mount directly on your existing tool battery platform, so there's no separate charger or extra battery to manage — just one power source doing double duty.

Charging Matters as Much as the Battery Itself

A battery's lifespan depends heavily on how it's charged, and mismatched or outdated chargers are one of the most common reasons a pack underperforms or wears out early. Our Battery Chargers collection has chargers matched to the amperage and voltage of the batteries in this lineup, so you're charging correctly rather than guessing.

If you're weighing a full switch between brands — say, moving your whole toolbox from Makita to DeWalt, or bridging Milwaukee gear with a DeWalt pack you already own — our guides on the Makita to DeWalt adapter and DeWalt to Milwaukee battery adapter break down exactly what's compatible before you spend money assuming it'll work.

Why Contractors and DIYers Choose Mach 1 Lithium

Every battery in this collection is built as a genuine, dependable alternative to paying full retail for an OEM replacement — same fit, same real-world performance, without the brand markup. Orders over $100 ship free, and every product here is backed by real customer support if something isn't right once it arrives. Whether you're outfitting a full crew across multiple brands or just replacing one aging battery in your own toolbox, this is the power tool battery lineup built to keep you working instead of waiting on a charge.
