What is アルカリ乾電池（単３形、１３本）?
Meet the quiet hero of any prepared household: Daiso's AA Alkaline Battery 13-pack, priced at just ¥330. Break that down and you're paying roughly ¥25 per battery — a price point that makes even budget supermarket multipacks look overpriced. Each cell is a standard AA (単3形) alkaline battery, measuring 1.41 cm in diameter and 5 cm in length, so it fits every AA-compatible device without a second thought.
The batteries use a manganese dioxide (二酸化マンガン) chemistry — the same core technology found in mainstream alkaline cells worldwide. Crucially, they are zero-mercury, which means responsible disposal is simpler and they meet modern environmental standards. The recommended use-by date stretches to a full 7 years from manufacture, making this an outstanding option for emergency kits and long-term storage. Country of origin is China, and the packaging is a no-frills, practical design — very on-brand for Daiso.
A quick note on safety (worth knowing before you bulk-buy): these are non-rechargeable cells. Never attempt to charge them. Keep them away from metal jewelry and direct sunlight, and always replace all cells in a device at the same time with batteries of the same type and age. Standard alkaline rules apply, but the 7-year shelf life gives you real flexibility in how and when you deploy them.

How to Use It — Hack Ideas
Primary Use: Power Everything AA
Remote controls, wall clocks, wireless mice, portable speakers, kids' toys, flashlights — AA batteries vanish fast in an active home. Having 13 on hand means you're never caught doing that "raid the TV remote" shuffle at midnight. CD and portable audio players (yes, they're back in style) are particularly hungry consumers, making this pack a natural fit for audiophiles on a budget.
Hack #1: The "Grab Bag" Emergency Kit Insert
Seal 4–5 batteries inside a small zip-lock bag along with a mini flashlight (also from Daiso, naturally) and tuck it into your go-bag or car glove compartment. The 7-year shelf life means you can forget about it — until the moment you desperately need it. Rotate once a year and you'll always have fresh power ready.
Hack #2: The Gift Wrapper's Secret Weapon
Buying a battery-powered toy or gadget as a gift? Tape two or three of these to the inside of the gift box with a ribbon. The "batteries included" surprise is a genuinely delightful touch — and at ¥25 a cell, it costs almost nothing to be the most thoughtful gift-giver in the room.
Reviews & Verdict
User sentiment around this pack is consistently warm. Frequent buyers highlight the sheer value arithmetic — thirteen cells for ¥330 simply doesn't compute at first glance, which is why so many reviewers describe a double-take moment in the aisle. CD enthusiasts and remote-control-heavy households in particular praise the pack as a staple repurchase.
Independent battery longevity comparisons published as recently as late 2024 place Daiso's current alkaline line in a surprisingly competitive tier — described as performing at roughly the same level as Daiso's own higher-grade white-label cells, and holding its own against name-brand competitors in low-to-medium drain applications. For high-drain devices like digital cameras or gaming controllers, premium lithium cells will still outperform, and that's worth keeping in mind.
The main caveat? The odd count of 13 (vs. the usual 4, 8, or 10) is quirky but actually useful — it nudges you to open a fresh pair for a device while keeping spares ready. Some buyers note the packaging is utilitarian rather than sleek, but frankly, these are batteries. Practicality wins. For anyone building a home emergency supply or simply tired of paying convenience-store prices for AA cells, this pack is a near-automatic buy.
Value Score: 88/100
A bulletproof price-per-unit ratio, a 7-year shelf life, and mercury-free chemistry earn this pack serious marks across every scoring category. It lands just shy of gem status only because performance in high-drain devices trails premium lithium options — but for everyday household use, it's great value, worth every yen.
