What's a good replacement for 3.6V 1/2AA PRAM battery?

I've used the Saft 1/2 AA cells mentioned above with success. In machines that I think I may forget about, I've desoldered the 1/2 AA holder and put in a CR2032 holder in its place:




The CR2032s are a nominal 3.2V but appear to work fine. They have less capacity but rarely leak and are cheap/readily available.
