most consumers are under the impression that rechargeable batteries don't last very long. After asking several people this question, I decided to look more closely at common rechargeable batteries with a question in mind: Are battery companies intentionally making rechargeable batteries with lower capacities in order to encourage the sale of more profitable throwaway alkaline batteries?

Why are Energizer "D" batteries so weak? To find out the answer, I decided to take one apart and see what was inside. As this picture reveals, inside the "D" battery is a much smaller battery! The Energizer "D" battery is actually just a cheap plastic shell surrounding a much smaller, low-capacity battery similar in size and capacity to an "AA" battery (2500 mAh).

This explains why the Energizer "D" rechargeable battery has such low power capacity to begin with. The company doesn't even try to make it a high-capacity "D" battery, it seems. They're filling part of the inside of the battery body with nothing more than cheap plastic and useless air. And how much does Energizer charge for this "D" battery? More than $12 each!

But is this all a conspiracy by Energizer? That's for you to decide. In my personal opinion, the Energizer company is deceiving consumers by packaging what is effectively an "AA" battery in a "D" size and shape, then marking up the price 400%, hoodwinking consumers into paying four times as much money for a battery that has extremely poor performance (by design).
