Our take on the DeWALT DCB126 12V MAX 5.0Ah Lithium-Ion Lightweight Compact Battery

The DCB126 is DeWalt's largest 12V MAX lithium-ion pack, a 5.0Ah (60 watt-hour) battery that fits every DeWalt 12V MAX tool and charger. It adds a fuel gauge LED so you can check charge before a job, and it weighs about 0.9 lbs, so it stays light in compact drills and drivers. The trade-off is bulk: it is longer than the 2.0Ah and 3.0Ah packs, which can make a small 12V tool feel nose-heavy. Owners rate it highly for runtime and build, and most complaints center on how much it adds to the size of the tool.
