📋 Read before selecting your variant. These batteries differ not just in capacity but in discharge characteristics. Choosing the wrong variant for your application will affect both tool performance and your experience with this product. Please read the full description before adding to cart.

Overview

Aftermarket replacement batteries fully compatible with the Milwaukee M18 platform — charges on your existing Milwaukee charger, works with all M18 tools without modification.

All variants use verified high-grade lithium-ion cells. Capacity and discharge ratings printed on the label correspond exactly to what is inside the pack. This is not a given in the aftermarket battery market — the majority of low-cost alternatives are sold on label claims alone, with cells that deliver a fraction of the stated performance.

If you have ever purchased a battery that ran out faster than expected or that underperformed under load — this is why.

Choose Your Variant — Read This First

Not all M18 batteries perform the same under load. Peak discharge current determines how a battery behaves in demanding tools — angle grinders, circular saws, impact wrenches — versus everyday tools like drills and drivers.

Selecting a standard-current battery for a high-draw tool will result in reduced performance, premature voltage sag, and shortened cycle life. Selecting a high-output battery for light everyday use is perfectly fine but unnecessary.

Why Not a No-Name Alternative

The aftermarket battery market is saturated with products that list impressive specifications on the label and deliver something entirely different inside. Common practices include understated cell counts, recycled or subgrade cells, and capacity ratings that exist only in print.

Every battery shipped from Mazurov Power Solutions contains exactly what the label states — verified cell grade, verified capacity, verified discharge rating. This is the only claim we make, and it is the only one that matters.

Warranty

12-month replacement warranty — the most straightforward warranty policy in this product category:

If your battery stops working within 12 months and there is no physical damage to the housing and no signs of moisture ingress — you receive either a replacement unit or a full refund. No ambiguity, no fine print.
