I just finished my first PVC LED hilt (Hooray!) but noticed the batteries were getting a little warm. So I took them out immediately, and tried them in a whole range of devices to find the same effect. The batteries in question are Energizer Ultimate Lithium L92-FR03 AAA 1.5v batteries. I don't think they should be getting warm at all. All the other non-lithium batteries I use don't Is this a normal side effect? Or should I be worried and buy new batteries? Thanks!
