Nothing Lasts Forever

It finally happened:

IIRC, I put a fresh Energizer Silver Oxide (China) in about 4 years ago – I'd forgotten what a PITA it is to get the battery cover off.

Really? The cover has a little latch & should pop right off, especially if its a real Mitutoyo. Now what you see inside might be dismaying (green/white chemical guts & internal corrosion). It pays to have a peek under the hood every year. Batteries are spit cheap these days but the instruments are not.

Real Mitutoyo from the mid-80's. To release the latch you need to push down at the top edge and slide the cover out. It's easier on my cheaper digital calipers since the batteries don't last as long and the cover latches get more exercise.

I've never had a Silver Oxide battery leak, nor any issssues with the larger LiOn coin cells; but Alkaline & cheap LiOn button cells should be checked more often (not sure what I'm going to use as a "check batteries" reminder if they do away with Daylight Saving.
