Our take on the Dewalt DCB122 12V Max 2Ah Li-Ion Battery

The DCB122 is DeWalt's 2.0Ah lithium-ion pack for its 12V Max cordless line. It is compact and light, which keeps 12V drills, drivers and saws balanced in the hand and reduces fatigue on long jobs. Lithium-ion chemistry means little self-discharge and no memory effect, so a pack left in a bag for months still holds charge. Against the 3.0Ah and 5.0Ah 12V Max packs it trades runtime for lower weight and a smaller footprint, which is the right call for drivers and light drilling rather than sustained cutting.

Questions and answers

Is the DCB122 worth it over the 3.0Ah 12V Max pack?
If you mostly drive screws and drill light holes, the 2.0Ah pack is lighter and keeps the tool balanced. Step up to the 3.0Ah or larger packs if you run saws or work continuously.
Which DeWalt tools does this battery fit?
It fits DeWalt 12V Max tools, including the 12V Max drill/driver, impact driver and several 12V Max saws and lights. It does not fit 18V or 20V Max tools.
Does it work with any DeWalt charger?
It charges on DeWalt 12V Max chargers. The 12V Max and 20V Max charging systems are separate, so a 20V Max charger will not take this pack.
How long does a charge last in storage?
Lithium-ion self-discharge is low, so a charged pack kept in a bag or toolbox holds most of its charge for months. Top it up before a big job.
Does the pack have a charge indicator?
No. The DCB122 has no built-in fuel gauge, so you check charge on the tool or charger.
Can I leave it on the charger?
DeWalt chargers manage the pack and stop charging when it is full, so leaving it on the charger between jobs is fine.
Where is the Dewalt DCB122 12V Max 2Ah Li-Ion Battery cheapest?
At Amazon, for $41.38, 48% under what the other stores charge, as of our latest check.
What do buyers say about the Dewalt DCB122 12V Max 2Ah Li-Ion Battery?
