What is ＬＲ４４アルカリボタン電池４個パック?
Meet the unsung hero of the Daiso gadget aisle — the LR44 Alkaline Button Battery 4-Pack. For just ¥110 (roughly $0.75), you get four LR44 alkaline cells, each measuring a compact 11.6mm in diameter × 5.4mm in height. These are manganese dioxide-zinc alkaline batteries, the industry-standard chemistry that delivers a stable 1.5V output per cell — exactly what countless small devices demand.
LR44 is one of the most universally used button cell sizes on the planet. Also sold under aliases like AG13, A76, and 357, this little disc powers an enormous range of everyday items: digital thermometers, kitchen timers, small LED flashlights, laser pointers, glucometers, hearing aids, and the battery compartments inside children's toys and holiday ornaments. Having a backup stash at ¥110 for four is genuinely hard to argue with — specialty electronics stores routinely charge ¥300–¥600 for a comparable pack.
Manufactured in China, these batteries carry no color variants or assortment options — just four identical, ready-to-deploy cells in straightforward packaging. There's nothing flashy about the design, and that's exactly the point. The value proposition is pure utility: small footprint, standardized voltage, and a price that makes hoarding a few packs in your junk drawer feel completely rational.
How to Use It — Hack Ideas
Primary Use: Swap dead LR44s in your digital thermometer, kitchen or bathroom scale, or laser pointer without making an emergency convenience store run at midnight. Keep one pack in your travel kit — countless travel accessories like luggage locks with digital displays, compact clocks, and UV sanitizer wands run on this exact cell.
Hack #1 — Emergency Watch Battery Stand-In: Many inexpensive fashion watches use SR44 silver oxide cells, which share the exact same physical dimensions as LR44. In a pinch, an LR44 will physically fit and temporarily power your watch — useful when you need your timepiece working for a trip but can't reach a jeweler. Just note it's a short-term fix, not a long-term replacement.
Hack #2 — DIY Candle & Fairy Light Maintenance Kit: Battery-operated tealights and fairy light strings — especially the tiny, decorative kind sold throughout Daiso itself — frequently run on LR44 clusters. Pair this four-pack with a small zip-lock bag and a mini screwdriver (also available at Daiso), and you've built a complete micro-battery maintenance kit for under ¥300 total. Perfect for holiday decorating season.
Reviews & Verdict
No user reviews are currently available for this specific product listing, which isn't surprising — button batteries aren't exactly review-magnet items. But within the broader Daiso battery category, the consensus from seasoned Daiso shoppers is consistent: these are everyday-tier alkaline cells, not premium long-life varieties, and they perform exactly as expected for the price.
For low-drain devices like thermometers, remotes, and decorative lights, the performance difference between a ¥110 Daiso pack and a ¥500 brand-name pack is negligible in real-world use. Where you might notice a gap is in high-drain applications or long-term storage — alkaline button cells from budget manufacturers can have shorter shelf lives, so plan to use these within a year or two of purchase.
The caveat is simple: don't use these to power a medical-grade device you depend on daily. For everything else — travel gear, kitchen gadgets, toys, and Daiso's own battery-powered products — this four-pack is a no-brainer grab. Toss two packs in your cart any time you're already shopping. You will eventually need them.
Value Score: 79/100
Alkaline chemistry, four cells, universal sizing, and a price that undercuts every pharmacy and electronics retailer around — the price-to-practicality ratio is excellent. It loses points only for the inherent limitations of budget-tier shelf life and the lack of premium credentials. Still, for casual everyday use, this is **great value, worth every yen**.
