The DEWALT 12V MAX 5Ah Lithium-Ion Battery 2-Pack (DCB126-2) gives you two high-capacity packs engineered to get the most out of your 12V MAX cordless tools. With more than triple the runtime of the original DCB120 battery, you’ll spend more time working and less time waiting on charges. The compact, lightweight design keeps the tool balanced, while the built-in 3-LED fuel gauge lets you check charge status at a glance.
Each 5Ah pack is designed to power every tool in the DEWALT 12V MAX family—drivers, impact wrenches, oscillating tools, and more. The higher capacity is ideal for long installs, repetitive fastening, or any job where a standard 1.5Ah pack just isn’t enough. And because DEWALT designed this pack with the same footprint as original 12V MAX batteries, it fits existing tools and chargers without adapter plates.
Compared to the older 1.5Ah cells, this 5Ah battery offers over 3x the runtime. That means fewer battery swaps, less downtime, and more productivity for the weekend woodworker or professional contractor. Whether you’re driving deck screws, assembling cabinets, or working through a full electrical rough-in, two 5Ah packs keep you moving.
Check charge status instantly with the 3-LED fuel gauge. The rugged housing resists jobsite abuse, and the lithium-ion cells deliver consistent power with no memory effect. Each battery is covered by a 2-year limited warranty and 90-day money-back guarantee for extra peace of mind.
Compatible with all DEWALT 12V MAX tools and chargers, this 2-pack is the smart upgrade for anyone who relies on the 12V platform. Add the DCB126-2 to your kit and eliminate the “dead battery” problem once and for all.

A higher-capacity battery means you can complete longer tasks without stopping. The DCB126-2 is perfect for drilling multiple studs, driving long screws, or running a reciprocating saw for extended cuts. Compared to a compact 1.5Ah pack, you get more than three times the runtime, plus the convenience of having two packs in the box so you can keep one on the charger while the other is in your tool.
To maximize the life of your battery, avoid fully draining it before recharging. Lithium-ion cells prefer shallow discharges. Store batteries at room temperature and avoid leaving them in a hot truck or direct sunlight. Every few months, clean the contacts with a dry cloth to ensure a solid connection.
Yes, this battery is compatible with all DEWALT 12V MAX tools and chargers, including older and newer models.
Charging time depends on the charger. With a DEWALT 12V MAX charger, a 5.0Ah battery typically charges in about 1.5–2 hours.
No, the DCB126-2 is specifically for the 12V MAX platform. 20V MAX tools require 20V/60V FLEXVOLT batteries.
The built-in fuel gauge uses three LEDs—all three lit indicate a full charge, one indicates low charge.
These batteries have revived my old 12V tools. The 5Ah capacity lasts all week. They charge faster than the originals. They're slightly bigger but still fit. The fuel gauge is helpful. I should have upgraded sooner.
Batteries last forever.
Long runtime, but they took a while to charge with my old charger.
Great for my drill and screwdriver. I can do projects without stopping.
