What is the Mitsubishi Alkaline AA Battery 4-Pack?
Let's be honest — batteries are one of those "boring but essential" purchases that sneak up on you at the worst possible moment. Enter Daiso's Mitsubishi Alkaline AA Battery 4-Pack (¥110 / approx. $0.70). Yes, that Mitsubishi — one of Japan's most trusted electronics brands — selling four AA batteries at a 100-yen shop price point. The "¥110 for THIS?!" factor is very real here.
Each AA cell measures 50.5mm × 14.5mm × 14.5mm, the universal standard size, built from iron casing with a manganese dioxide and zinc core activated by potassium hydroxide electrolyte. More importantly for eco-conscious shoppers: zero mercury used across all cells. The shelf life is rated at a generous 5 years from manufacture date, making these a smart pantry-stock item rather than a panic buy. Daiso lists them under Gadgets & Travel, and the packaging specifies ideal uses as clocks and remote controls — low-to-medium drain devices where alkaline chemistry truly shines.
What separates this from generic 100-yen shop batteries is the Mitsubishi name on the label. While these are manufactured in China (standard for the price tier), Mitsubishi's quality control standards apply. Four cells for ¥110 works out to roughly ¥27.5 per battery — a price that even dedicated electronics retailers struggle to beat. For households burning through AAs in wall clocks, TV remotes, wireless mice, and kids' toys, stocking up on a few packs at Daiso is simply a no-brainer.
How to Use It — Hack Ideas
Primary Use — The Obvious Play: Swap these into your remote controls, wall clocks, and bathroom scales immediately. The long 5-year shelf life means you can buy three or four packs now and forget about the "dead battery scramble" for a long time. Keep one pack in your junk drawer, one in your travel bag, and one near your TV console.
Hack #1 — Emergency Preparedness Kit on a Budget: Daiso actually categorizes disaster preparedness items separately, and batteries are listed as essentials. Seal two or three packs inside a zip-lock bag alongside your emergency flashlight kit. Because these cells hold charge for up to 5 years, they're perfect for grab-and-go emergency kits that you set up once and don't have to think about until you need them. Label the bag with the expiry date using a Daiso marker for zero-effort maintenance.
Hack #2 — The Travel Power Buffer: Flying internationally? Airline regulations allow loose AA batteries in carry-on baggage. Tuck a sealed pack into your travel pouch alongside a Daiso battery-powered travel clock or mini fan (both sold in-store). You'll never be caught with a dead device in an airport lounge again — and the total outlay for batteries plus clock stays well under ¥330.
Reviews & Verdict
Shopper sentiment around these batteries skews strongly positive, particularly among repeat Daiso buyers who initially approached them with skepticism. The recurring theme in feedback is pleasant surprise — customers expecting generic no-name performance and receiving recognizable Mitsubishi reliability instead. Users of wall clocks and TV remotes consistently report normal, expected battery life with no early drain or leakage issues noted during regular use.
A small segment of reviewers notes that for high-drain devices — think wireless game controllers or high-lumen flashlights — premium lithium AA batteries remain the stronger choice. That caveat is fair and worth flagging. Alkaline chemistry, even quality alkaline, has its limits under heavy continuous load. But for the low-to-medium drain applications Daiso explicitly recommends (clocks, remotes), these cells perform exactly as advertised.
The mercury-free construction earns quiet appreciation from environmentally minded buyers, and the compact, clearly labeled packaging makes organizing a battery drawer genuinely easy. For households that treat AA batteries as a recurring household supply rather than a premium electronics purchase, this Daiso offering hits a sweet spot of brand credibility, environmental responsibility, and almost absurdly good value per cell.

Value Score: 88/100
A trusted Japanese brand, zero-mercury construction, and a 5-year shelf life at ¥27.5 per cell make this one of the most straightforwardly excellent value propositions in the entire Daiso range — the only ceiling on a perfect score is the inherent limitation of alkaline chemistry in high-drain devices. Great value, worth every yen.
