Exciting thread topic alert!

Very occasional poster here. Infrequent lurker.

As the weather is starting to turn, I thought I'd do a pre-Winter shakedown of my system and fire it up for the first time since March.

All was well, but I discovered that something didn't shut down properly.

Tracked down my issue to a duff set of batteries.

My question to you all is this:

what batteries do you use in your rads?

I'd been replacing mine every year with a set of Costco own brand.

Has anyone given Enerloops a try?

I'd never heard of them until recently, but the fact that they don't leak seems like it could prevent having to buy a new rad "thing" (Mine are HR80, and I don't know the correct lingo for the updated ones!)
