Our take on the DeWALT 12V MAX XR 5.0Ah Lithium Ion Battery (DCB126)

The DeWALT DCB126 is a 12V MAX XR lithium-ion battery pack with 5.0Ah of capacity, the largest in DeWALT's 12V MAX line. It fits XTREME 12V MAX tools and 12V MAX chargers and adds a built-in LED state-of-charge gauge so you can check power before starting a task. The extra capacity means longer runtime than the 2.0Ah and 3.0Ah packs, at the cost of more weight in compact tools. It suits owners of DeWALT 12V drills, drivers and oscillating tools who want fewer battery swaps, and it is a sensible spare for anyone already on the 12V MAX platform.
