Jacob ★★★★★

My digital caliper was flashing a low battery warning, and this SR44 dropped right in and had it reading again in seconds. 1.55 volts and it's still going strong after a couple months of daily use in the shop. Nice to finally have a spare that actually fits instead of guessing at the size.

Adam R. ★★★★★

I was worried my caliper needed a proprietary battery, but these LR44W equivalents dropped right in and it's been reading accurately for weeks. The 190 mAh capacity means I'm not swapping them out constantly like the cheap ones I tried before.

Aurora A. ★★★★★

Swapped these into my digital caliper and it's been reading dead-on for weeks now. The 1.55V output matches what the old ones put out, so no calibration weirdness. Nice to have spares that actually interchange with the AG13s I had lying around.
