Rechargeable is the ONLY way to go now. I have Resounds. They come with a charging dock that you just drop the aids into at night. A full charge is good for two days, and the charger itself has a battery in it that's good for up to two full charges of the aids. In theory, you could take the charger along on a trip and not need to plug it in for a week.
The aids are sealed, too. Which means they're much more resistant to an inadvertent wetting like a rain shower.
