Battery Platform Guide: DeWalt, Milwaukee, Makita, and the Rest

DeWalt 20V MAX

DeWalt's 20V MAX platform is the largest professional cordless ecosystem. The "20V MAX" branding is nominal voltage, meaning the batteries are actually 18V lithium-ion cells. 20V is the peak no-load voltage. Marketing aside, the platform covers 200+ tools across construction, woodworking, automotive, and outdoor categories. Battery capacities range from 1.5Ah compact packs ($30 to $40) to 15.0Ah FLEXVOLT packs ($150 to $200).

The FLEXVOLT system deserves special mention. FLEXVOLT batteries automatically switch between 20V and 60V depending on the tool they are inserted into. A FLEXVOLT battery in a standard 20V drill runs at 20V. The same battery in a FLEXVOLT table saw runs at 60V. This means you can own one set of batteries that works across both standard and high-power tools without buying into a separate platform. The DCD800 drill and DCF850 impact driver are the current flagships in the standard 20V line.

DeWalt's strongest categories are general construction tools, woodworking (the FLEXVOLT table saw and miter saw are popular on job sites), and outdoor power equipment. The platform is weakest in specialty trade tools, where Milwaukee has deeper coverage for plumbing, electrical, and HVAC.

Milwaukee M18

Milwaukee's M18 platform targets tradespeople: electricians, plumbers, HVAC techs, and general contractors. The lineup runs deep, with 250+ tools and category-specific options you will not find elsewhere, including the M18 FUEL ProPex expansion tool for plumbers and the M18 FORCE LOGIC crimper for electricians. Battery options go from 2.0Ah ($35) to 12.0Ah HIGH OUTPUT packs ($170).

Milwaukee also runs the M12 platform for compact tools. M12 drills, impacts, and specialty tools are smaller and lighter, built for overhead work, tight spaces, and lighter duty. Some professionals carry both: M18 for primary power tools and M12 for tools that live in a pocket or tool pouch. The two platforms do not share batteries, so it is a separate investment. An M12 starter kit (battery, charger, and one tool) runs $100 to $150.

Milwaukee's ONE-KEY system adds Bluetooth tool tracking and customizable performance profiles on select M18 FUEL models. You can set torque limits, track tool location, and lock tools remotely. It is most useful for contractors managing fleets of tools across multiple job sites.

Makita 18V LXT

Makita's 18V LXT platform has been around since 2005, making it one of the longest-running lithium-ion cordless systems. The 300+ tool count includes some unusual entries like cordless coffee makers and Bluetooth speakers, but the core power tool lineup is competitive with DeWalt and Milwaukee at every tier.

Makita tools tend to be slightly more compact than their DeWalt and Milwaukee equivalents. The XDT16 impact driver and XFD16 drill are among the shortest in their class, which matters for working in tight spaces between joists or inside cabinets. Battery capacities go up to 6.0Ah on standard packs and 8.0Ah on the newer LXT X2 (36V) configuration, which uses two 18V batteries in series for tools that need more voltage, like the 36V circular saw.

The platform is popular internationally and has broad availability. Makita's reputation for motor longevity is well-documented in professional reviews and trade forums. For users who value compact size and long-term reliability over the widest possible tool selection, Makita is a strong choice.

Ryobi ONE+

Ryobi ONE+ is the value platform. Over 300 tools at prices 30% to 50% below Milwaukee and DeWalt. Battery compatibility spans back to 2004, which means an 18V battery bought today works in a ONE+ drill from 20 years ago. That backward compatibility is unmatched in the industry.

The tradeoff is build quality and performance ceiling. Ryobi tools use thinner housings, less refined motors, and simpler electronics than professional-grade brands. They work fine for home projects. They just do not survive the same abuse levels that a job site dishes out daily. For homeowners and weekend DIYers, Ryobi is hard to beat on value. The PBLID02 brushless impact driver and PBLDD01 brushless drill are genuinely good tools at $80 to $100 price points.

Ryobi's biggest advantage beyond price is ecosystem breadth in the home category. Lawn mowers, string trimmers, pressure washers, fans, lights, glue guns, and even a portable generator all run on ONE+ batteries. If you want a single battery powering every cordless device you own, Ryobi covers more ground than anyone else. See our new homeowner's tool guide for more on which Ryobi tools make sense for a first tool kit.

Ridgid, Bosch, Kobalt, and Craftsman

Ridgid (Home Depot exclusive) runs the 18V Octane platform. The standout feature is the Lifetime Service Agreement: register your tool online and Ridgid covers parts and labor for the life of the tool, including batteries. That warranty is real and enforceable, and it is the best warranty in the power tool industry. The tool lineup is smaller than the Big Three (around 60 tools) but covers the core categories well. The R86116 brushless drill and R862311B impact driver are solid performers priced between Ryobi and DeWalt.

Bosch's 18V system is technically excellent but has a smaller tool selection in North America, around 40 tools. Bosch pioneered the electronic motor protection that everyone else now copies, and their engineering is consistently precise. But the ecosystem breadth does not compete with platforms that offer 200+ tools.

Kobalt (Lowe's exclusive) runs a 24V MAX platform with brushless motors across the line. Pricing sits between Ryobi and DeWalt, typically 10% to 20% below DeWalt for comparable specs. The KID 1324A-03 impact driver and KCS 124B-03 circular saw are competitive. Craftsman (also at Lowe's) uses V20 (20V) and V60 (60V) platforms with broad coverage for home use. Both brands are solid choices for homeowners who shop at Lowe's and want one ecosystem for everything from drills to lawn mowers.

How to Choose

If you are already invested in a platform with 3 or more batteries, stay with it unless there is a specific tool you need that your brand does not make. The switching cost rarely justifies the change. Your existing batteries, chargers, and bare tools represent $300 to $1,000 of sunk cost that becomes worthless if you switch.

For new buyers starting from scratch, the decision breaks down by use case:

• Budget-conscious homeowner — Ryobi ONE+. Best value, largest home-use ecosystem, backward compatibility to 2004.
• Serious DIYer or semi-pro — DeWalt 20V MAX or Milwaukee M18. Professional-grade tools with deep lineups. DeWalt edges ahead in woodworking, Milwaukee in trade-specific tools.
• Warranty matters most — Ridgid 18V. Free lifetime coverage including batteries is unbeatable.
• Compact size and legacy compatibility — Makita 18V LXT. Longest-running platform, consistently compact tool bodies.
• Lowe's shopper — Kobalt 24V or Craftsman V20. Single-source convenience with solid mid-range performance.

Regardless of platform, buy your first tool as a kit (drill or drill/impact combo) to get the charger and 2 batteries. After that, every subsequent tool should be a bare tool at $40 to $80 less than the kit price. See our cordless drill guide for picking the right starter kit.

Frequently Asked Questions

Are DeWalt 20V MAX and 18V the same thing?

Yes. The batteries are 18V lithium-ion cells. "20V MAX" is the peak voltage when the battery is fully charged and under no load. Under actual use, they deliver 18V nominal. Milwaukee, Makita, Bosch, and Ridgid label their equivalent batteries as 18V. DeWalt, Craftsman, and Kobalt use the higher peak number. The batteries are functionally equivalent voltage.

Can I use batteries from one brand in another brand's tools?

Not directly. Each platform has a proprietary battery interface. Third-party adapters exist (for example, adapter plates that let Milwaukee batteries fit DeWalt tools) but they void warranties, may not deliver proper voltage regulation, and can damage tools or batteries. Stick to matching brands.

How long do lithium-ion tool batteries last?

Expect 500 to 1,000 charge cycles, which translates to 3 to 5 years of regular use. Runtime per charge depends on capacity (measured in amp-hours) and the tool's power draw. A 5.0Ah battery lasts roughly 2.5 times longer per charge than a 2.0Ah battery on the same tool. Store batteries between 40% and 60% charge in a temperature-controlled space for maximum lifespan. Avoid leaving them on the charger continuously or storing them in a hot garage.

Is higher voltage always better?

No. Higher voltage means more potential power but also more weight and cost. A 12V drill weighs 2 to 3 lbs. An 18V/20V drill weighs 3.5 to 5 lbs. For overhead work and all-day use, the lighter tool reduces fatigue significantly. Use 12V for light duty and tight spaces, 18V/20V for general work, and 36V/60V for high-draw tools like table saws and miter saws.

Should I buy bare tools or kits?

If you already have batteries and a charger for a platform, buy bare tools. They cost $40 to $80 less than the kit version. If you are starting fresh, one kit (drill or drill/impact combo) gets you the charger and 2 batteries. After that, every subsequent tool should be bare.
