Our take on the DeWalt DCB126YY 12V MAX 5Ah Lithium Ion Battery

The DeWalt DCB126 is a 12V MAX lithium-ion battery pack with 5Ah of capacity, or 60 Wh of energy. It is the largest pack in DeWalt's 12V MAX line, so it gives Xtreme 12V MAX drills, drivers and saws noticeably longer runtime than the compact 2Ah and 3Ah packs, at the cost of extra bulk and weight in the handle. A built-in state-of-charge LED shows remaining power without a tool. It suits anyone already on the 12V MAX platform who wants fewer battery swaps, and it charges on standard DeWalt 12V MAX chargers.

Questions and answers

How long does the 5Ah pack run compared with the 2Ah?
At 5Ah it holds roughly two and a half times the energy of a 2Ah pack, so expect about that much more runtime in the same tool. Actual time depends on the tool and the load.
Will it fit my 20V MAX DeWalt tools?
No. It is a 12V MAX pack and fits only Xtreme 12V MAX tools and 12V MAX chargers. 20V MAX tools take the slide-on 20V packs.
Does it come with a charger?
No. The box contains one DCB126 5Ah battery. You need a DeWalt 12V MAX charger, which you may already own from a kit.
How do I check the charge level?
Press the state-of-charge button on the pack and the LED indicator shows how much power is left, so you can top it up before a job.
Is it worth it over the smaller 12V MAX packs?
If you run tools for long stretches, the extra runtime saves swaps and downtime. For light, occasional use the smaller packs are lighter and handier.
Where is the DeWalt DCB126YY 12V MAX 5Ah Lithium Ion Battery cheapest?
At Walmart, for $70.16, 46% under what the other stores charge, as of our latest check.
