The DeWALT DCB205 20V MAX 5.0Ah Lithium Ion Batteries, 4-Pack is a set of four 5.0Ah battery packs for DeWALT 20V MAX cordless tools. This is a cordless tool battery set designed for contractors and serious DIYers who run multiple 20V MAX tools and need dependable run-time. Model Number DCB205-2-2X packages two DCB205-2 two-packs, for a total of four DCB205 batteries.

The DCB205 is DeWALT's premium XR 5.0Ah pack. DeWALT rates it for up to 60% more capacity than the standard 20V MAX DCB200 pack. On the job, that means a circular saw makes more rips per charge, a drill bores more holes, and an impact driver sinks more screws before you have to walk back to the charger.

Lithium-ion chemistry gives the DCB205 no memory effect and virtually no self-discharge. You can top off a half-used pack without hurting its capacity, and a fully charged pack left in the truck for a few weeks is still ready to work when you need it. That reliability is a big part of why the 5.0Ah pack is a standard in so many DeWALT kits.

Each pack weighs 1.4 lbs, light enough that it doesn't make a drill or driver feel nose-heavy during overhead work. The 3-LED fuel gauge on the side of the pack shows the state of charge at the push of a button, which saves the guesswork of whether a battery will finish the job.

A note on the name: 20V MAX is the maximum initial voltage measured without a load. Nominal voltage is 18V. Every DCB205 fits the full line of DeWALT 20V MAX tools and charges on DeWALT 20V MAX chargers, so these packs slot straight into the kit you already own.

Four packs is where cordless work gets easier. One battery each in the drill, impact driver, and saw, with the fourth on the charger, keeps the rotation going without anyone waiting on power.

Who should buy it? Carpenters, remodelers, electricians, plumbers, and DIYers with a growing 20V MAX collection, or anyone replacing worn-out packs all at once. If you need maximum run-time for high-draw tools, step up to a larger-capacity pack. For everyday drilling, fastening, and cutting, the 5.0Ah DCB205 is the right size, and a faster charger like the DCB118 fan-cooled fast charger helps a single-port setup keep up with four packs.

The DeWALT DCB205 20V MAX 5.0Ah Battery 4-Pack Is the Everyday Power Supply

Four of DeWALT's most popular packs in one box, which is how many you actually need once your 20V MAX kit grows past two tools.

• Who it's for: Contractors and DIYers running several 20V MAX tools, or anyone replacing a set of aging batteries.
• Why it stands out: 5.0Ah capacity at 1.4 lbs per pack, a 3-LED fuel gauge, and fit across the whole 20V MAX line.
• Worth knowing: Batteries only, no charger. For the longest run-time on high-draw tools, look at the larger packs in the DeWALT 20V MAX batteries lineup.

• Why is it called 20V if it's 18V? 20V MAX is the maximum initial voltage measured without a load. Nominal voltage is 18V.
• Will these work in my older 20V MAX tools? Yes. The DCB205 is compatible with DeWALT 20V MAX tools and chargers.
• Is a charger included? No. This set is four batteries only.
