So the difference is 0,7mm. Metric system is that easy :)

I agree :) it's just the catalog I looked in only listed in inches :(

It depends on the battery tolerance.

A made in China Sunbeam brand 2032 from Dollar Tree did NOT work in my 2011 fob.

I'll try Advance Auto 2025 at two for $4.

My current one is Harbor Freight 2025.

They are cheap but don't last very long.

CR2025 = Diameter: 20 mm. Thickness: 2.5 mm. Capacity: 160 mAh,
CR2032 = Diameter: 20 mm. Thickness: 3.2 mm. Capacity: 220 mAh

.7mm(a little less than 1/32 inch) difference in thickness and 60 more mAh, 38% more capacity to be correct. I'll take the chance!][/quote]

The above is from 3 years ago...Bought a card of 10 each CR2032 cells for $15 total three years ago; used one in my fob; here we are three years later and I just replace it again and I have 4 left; used the other five for other products and gave a few away. the CR2032 is a popular size that is used in remotes, backups in control devices, etc. A good quality cell has a self life of about 10 years and the CR2032 has worked fine and still is working fine in my FOB

I bought a dozen Sony CR2032 for less than ten bucks about a year ago. My electronic scale uses them and the shelf life is good, so I figured I'd get a bunch. Just replaced both fobs, they work great.

As an update to this topic which got a little contentious early on in its life,

a 2032 battery fitted nicely in our 2012 fob and is working well.

As to earlier reports that a 2032 will not work in a 2011 fob - not sure why that would be. Doubtful that the fobs are any different.

I suppose manufacturing discrepancies of cheaper battery brands could be such that it may not be possible to snap the fob back together without losing the integrity of the -ve spring contact.

But more likely IMO is that assuming all purchased batteries in a pack are good enough to supply the required nominal 3V. A typical fresh 2032 will register 3.4V. It looks like anything below about 2.9V just won't work.
Whether it's old stock or a manufacturing defect I can certainly believe that a given 2032 might not work at all in a Leaf fob but appear to work ok in some other less sensitive 2032 application such as a light or even a timepiece.

If a 2011 Leaf owner has the ability to confirm a replacement battery has a healthy voltage reading and takes their time in carefully installing it I see no reason to discourage them from trying a 2032 instead of a 2025.

That's 2.5 years on this fob battery. I've switched to the second fob for a while and have put the replacement on my to-do list.

I like it, good info.
