This page contains descriptions of the Energizer AA and AAA Rechargeable Batteries. Find detailed Information about AA Rechargeable Batteries, AAA Rechargeable Batteries.
 

Why are these just AA batteries in a shell?

Why are these batteries, just like your rechargeable D batteries, simply AAs in a larger shell? No, NiMH batteries have a similar charge density to alkalines. There are many NiMH D batteries that boast 120000 mAh, 10000 mAh being the norm. Many C NiMHs are 5000 mAh (notice that charge capacity increases roughly exponentially with each battery size with base 2). The question is not "bang for your buck" rechargeables vs. alkalines. The question is why will you not make C and D sized batteries that are true C and D sized batteries? There are many on the market. The only advantage to having a much lower charge capacity is the recharge time, otherwise what you are doing is almost deceitful. You are selling AA batteries for a higher cost.

I am not bashing your products. I own 8 rechargeables made by you guys and they have lasted years and they hold their charge very well. I'm asking why you guys will not make true, 5000 mAh C batteries and 10000 mAh D batteries. Alkaline capacities are about 1250, 2500, 5000, and 10000 mAh for AAA, AA, C, and D batteries respectively. Don't give me the nonsense "alkalines don't use mAh measurements"...that's silly. Batteries hold charge. Accessible charge varies depending on current but that goes with any battery.

I have devices that use Cs and Ds, but since you refuse to make true Cs and Ds, I can't justify buying them when I could just use a small magazine and use AA batteries in place of Cs. They are the same length. What is your rationale, other than faster charge time, for this decision that you guys have been very rigid about despite many stories on the internet regarding this practice of yours?
