kunying AG13 LR44 Batteries (25-Pack) - Long-Lasting 1.5V LR44 Alkaline Battery for Watches, Toys, Calculators & Medical Devices | AG13/A76/357/L1154F/SR44 Equivalent | Leak-Proof Design & Mercury-Free

A practical 25-pack of LR44s that does what it says

I keep a small drawer of button cells for watches, calipers, toys, and the odd gadget that only wakes up once a year. After running through a handful of devices with the kunying LR44 batteries, I’ve come away with a clear impression: this is a no-frills, budget-friendly pack that performs reliably for everyday use, with a few caveats if your application is picky about voltage.

What you get and how it’s packaged

The pack I tested contains 25 alkaline LR44 cells, each individually sealed on a card. The packaging is straightforward and avoids the frustration of flimsy blisters that spill cells everywhere; I could pop one out without disturbing the rest. Each cell is clearly labeled (LR44/A76/AG13/357/SR44-equivalent), which helps when you’re matching codes across different devices or manuals.

The cells are mercury-free and carry CE and RoHS marks. That’s table stakes these days, but still good to see. The manufacturer claims a leak-resistant design and an operating range from −22°F to +140°F. I can’t verify multi-year leak resistance, but I did store a few in a garage that dipped into the 20s (°F) and used others after leaving them in a hot car for a weekend; no swelling, sweating, or corrosion showed up in the short term.

Compatibility and where they fit well

LR44 goes by many names—AG13, A76, 357, SR44—and these cells slot into all the usual suspects: analog and digital watches, kitchen timers, digital calipers, small LED book lights, laser pointers, and children’s sound books. I also used them in a light-up dog collar module and a bicycle valve-cap light (both higher-drain, intermittent uses) without issue.

A quick note on equivalency: SR44 (silver-oxide) is the same size as LR44 (alkaline), but the chemistries differ. Silver-oxide cells hold voltage flatter as they discharge, which matters in some cameras, meters, and medical devices that expect a steady 1.55V. The kunying cells will power those just fine, but you may see earlier or more noticeable performance dip than with true SR44. If your device explicitly recommends silver-oxide, that’s worth following. For most everyday applications, these alkalines are perfectly adequate.

Performance: measurements and real-world use

Fresh out of the pack, I spot-checked ten cells with a multimeter. Open-circuit voltages ranged from 1.57V to 1.60V, which is what I expect for a healthy alkaline button cell. Under a modest 5 mA load, the sample I measured sat around 1.50–1.52V initially. Pushing to a 30–40 mA load (typical of small LED toys), voltage dipped into the 1.30–1.40V range and sagged a bit more over time—again, typical LR44 behavior.

Capacity is harder to assess precisely without a controlled rig, but in a slow, low-drain discharge to 0.9V, my rough tests suggest these are in the ballpark for alkaline LR44s (think roughly low 100 mAh at gentle loads). In practice:

• Watches: I replaced three quartz watch cells. All started immediately and kept time over a month of observation with no drift attributable to the battery.
• Digital caliper: Woke right up and stayed on my bench for weeks of occasional use. No random resets or fading LCD segments.
• LED book light: Bright out of the gate; noticeable dimming after a few long reading sessions, consistent with alkaline LR44 chemistry. Swapping cells restored brightness.
• Children’s sound book and novelty greeting card: Worked flawlessly; sound output remained clear, with gradual drop-off rather than sudden failure.

Compared with name-brand A76/LR44 cells (Energizer, Duracell) I’ve used, the kunying pack feels very close in everyday use. If there’s a difference, it shows up under sustained higher drains, where brightness or output falls off a bit sooner. For me, that’s an acceptable trade-off given the bulk pack’s price.

Consistency and quality control

Consistency matters more than peak performance for a bulk pack, and here the kunying cells did well. The open-circuit voltages were tight, and I didn’t encounter any duds or cells that read low out of the blister. Contacts are clean and burr-free, and the crimps look uniform across the lot. I also appreciate that the polarity markings are easy to read—saves a few minutes of squinting when you’re swapping a watch battery.

I can’t assess multi-year shelf life yet. After roughly three months, the unopened cells I re-measured still read in the 1.58–1.60V range. If you store them in a cool, dry place and keep them in their blisters until needed, I’d expect the usual multi-year usability typical of alkaline buttons.

Safety and handling

Being mercury-free is important, but button cells still require care:

• Keep out of reach of children and pets—ingestion is dangerous.
• Don’t mix new and used cells in multi-cell devices (some gadgets stack two or three LR44s).
• Remove batteries from seldom-used products to reduce leak risk.
• Recycle properly where facilities exist; don’t toss them loose in the trash.

I didn’t see any leakage in devices or in storage during my testing period.

Where these shine—and where they don’t

Strengths:
- Everyday reliability across common gadgets
- Good unit-to-unit consistency and no early failures in my sample
- Clear labeling and practical packaging for long-term storage
- Mercury-free, with a claimed wide operating temperature range
- Strong value when you need multiple spares

Trade-offs:
- As alkalines, they show the typical voltage sag under higher loads
- For devices calibrated around the flatter discharge of silver-oxide (SR44), these will work, but a true SR44 still performs better over the entire discharge
- No published, independently verified capacity spec (common at this price tier)

If your primary uses are watches, small lights, remotes that truly specify LR44, calipers, toys, and novelty items, this pack fits that niche well. If you’re shooting a classic camera that’s picky about meter voltage or running medical instruments that specify SR44, I’d step up to silver-oxide.

Value and everyday practicality

The whole point of a 25-pack is to have the right cell on hand when something stops working. On that front, this pack has already saved me three separate trips to a drugstore. Cost per cell is low, the performance is predictable, and I’m not rationing batteries for fear of running out. That convenience is a big part of the appeal.

A small practical tip: jot the install date inside battery compartments where there’s room (or keep a note on your phone). It helps track longevity across devices and spot any outliers early.

The bottom line

The kunying LR44 batteries are a sensible, cost-effective choice for most LR44/AG13/A76/357 use cases. They’re consistent, easy to store and identify, and performed as expected across a spread of low- and moderate-drain devices. They’re not a substitute for silver-oxide in applications that demand a flat discharge curve, but that’s a matter of chemistry, not quality.

Recommendation: I recommend this 25-pack if you want reliable, everyday LR44 power at a reasonable price for watches, calipers, toys, small lights, and similar gadgets. If your device specifies SR44 for accuracy or long, steady output, opt for silver-oxide cells instead. For everything else, this pack is an easy, practical pick to keep your small electronics running.
