Battery, AG10 Alkaline

I needed a replacement for a worn-out LR1130 and this AG10 fits perfectly at 11.6 mm wide. The 1.55 volt output is spot on for my calculator.

Popped these into my DRO display dial and the 1.55 volts brought it right back to life. The 65 mAh capacity seems solid for the size, and they fit perfectly in the tight compartment. Glad I found the right replacement for LR1130.

My calipers confirmed the 11.6mm diameter and 3.1mm thickness right out of the package, and they clicked into the DRO dial without any wobble. The 1.55 volts held steady during a full afternoon of measuring, which is exactly what I needed for repeatable readings.
