Our take on the DEWALT DCB126 12V MAX 5.0Ah XR Lithium-Ion Battery

The DeWalt DCB126 is a 12V MAX XR lithium-ion battery pack rated at 5.0Ah, the highest-capacity pack in DeWalt's 12V line. It fits DeWalt 12V MAX cordless tools and chargers that accept XR packs, and DeWalt claims more than triple the runtime of the standard 12V packs. That makes it the pick for anyone who runs compact drills, drivers or oscillating tools hard and wants fewer battery swaps. The trade-off is weight and bulk: a 5.0Ah pack is noticeably heavier than the 2.0Ah packs most 12V kits ship with, so it suits longer sessions more than pocket carry.
