I can't believe it! Just when we thought we've got the Duracell battery color scheme figured out, those folks at Duracell pulled another cheap trick out of their collective... hat!
To recall, here is the color scheme for Duracell AA/AAA batteries:
- Duracell alkaline cell has the famous 'copper top' and a black bottom
- Traditional Duracell Rechargeable NiMH (DC2400)
cell is green and black in color
- Newer Duracell Pre Charged NiMH
cell has a 'copper top' and a green/black bottom
The latest batch of rechargeable AA/AAA NiMH cells from Duracell all have the 'copper top' and green/black bottom, similar to that for 'Pre Charged' version. However, those cells don't say 'Pre Charged' on them. Instead, they have their capacity printed (2650mAh for Duracell DC1500 AA
, 1000mAh for Duracell DC2400B4N AAA
). It is important to know that: those are NOT the low-self-discharge type like Sanyo Eneloop
. They are traditional NiMH cells, which have higher capacity but suffer from rapid self-discharge problem. So even though their prices may look attractive, those are no bargains.
Remember: "If it doesn't say 'Pre Charged', put it back!"

I noticed that this Duracell package now says "DuraLock" and "Recharge up to 300x" on it. But the term "DuraLock" is applied to all Duracell batteries, including alkaline, Pre-Charges and ordinary NiMH batteries. So it sounds like just a marketing gimmick. Also note that most Pre-Charged NiMH batteries claim to be able to recharge up to 1000x, or even 1500x in the case of Sanyo eneloop
