I may be late to the party on this, but I think I'm going to switch over from alkaline AA and AAA batteries to lithium for misc stuff around the house. The main reason is that I'm sick of the alkalines in infrequently used and low power stuff (e.g. the fish and table scales I keep in the kitchen) leaking. The lithiums are more expensive up front, but they last longer. However the key issue here is leaking - from what I've read, lithium batteries will not leak.

Does anyone out there have any experience with long-term use of lithium AA or AAA batteries and if so, have you ever had problems with them leaking?

TIA
