I've been using these LR44 button batteries in my digital calipers at work, and they’ve been surprisingly reliable. No sudden power drops mid-measurement—just steady performance.
What impressed me most was how they handled my kid’s noisy dog toy (the one that barks when thrown). After three months of constant ‘good puppy!’ announcements, they’re still going strong. The toy actually wore out before the batteries did.
The packaging deserves a shoutout too. The child-resistant case actually opens like a normal human would open it, unlike some ‘safety’ packaging that requires scissors and a prayer.
Are they Duracell-level? No. But at this price point, I can replace them twice and still save money. For non-critical devices where you just need consistent power without breaking the bank, these are perfect.
