Panasonic Cr Lithium Battery

Panasonic Cr Lithium Battery
Could this battery replacement work?

I own a swiss army knife with digital altimeter that needed a battery replacement. According to the user manual, the battery should be Panasonic CR 1225, 3V. However, I found that an alkaline AG10 (LR1130) fits perfectly well. The digital altimeter seems to work well, despite the fact that the AG10 battery delivers 1.5 V (and not 3 V as the CR 1225). My question is… will the digital altimeter work well with half the recommended voltage? Can the electronics be damaged if using 1.5 V instead of 3V? I also found the the CR 1225 is a lithium battery, whereas the AG10 is an alkaline one… would this affect the performance? Any advice will be highly appreciated. Thanks.

The electronics will not get damaged. Over voltage is usually a problem. However cold may drop the voltage even further and render your altimeter say ‘blank’ or useless. Use proper size battery.
