Energizer rechargeable "D" just "AA" cells inside

NewsTarget took a look at one of the most common sizes of rechargeable batteries sold by a leading US brand, the Energizer "D" cell used in most full-sized household flashlights, among other applications. What intrigued them was that the battery's stated capacity is only 2,500 mAh, the same capacity as given for the physically much smaller "AA" size batteries.



They took apart one of Energizer's "D" batteries and found that it contained a much smaller battery inside, comparable in size to an "AA" battery, surrounded by empty airspace and a plastic shell. The "D" cell actually turned out to be just an "AA" cell inside a larger casing.



Since Energizer's rechargeable "AA" battery costs only about $3, but its rechargeable "D" battery costs $12, or four times as much, they reckon you're getting ripped off every time you buy a rechargeable "D" battery from Energizer. It would seem they've got a point.

I sent a complaint on Energizer's website. We'll see how that goes. I'm very disappointed...
