Thirsty Batteries Tell Rechargers How Fast to Pour

With some battery rechargers, restoring a couple of double-A's can take up to eight hours. But with Rayovac's new I-C3 system, batteries can be charged during a coffee break.

I've seen these in the stores. Think it only takes about 15 minutes to recharge them, but you have to use this newer type battery, if I understand the article correctly.
