How to Choose Household Batteries (家用電池) in Taiwan: AA and AAA, Zinc-Carbon, Alkaline, and Rechargeable, and the Cost per Battery
The remote control does not respond, the clock has stopped, the flashlight has gone dim, and every home needs some AA and AAA batteries in stock. But on the shop page there are zinc-carbon, alkaline, and rechargeable ones, with claims such as "super long lasting", "big power", and "Japanese quality", so which one should you buy for what? This guide explains the differences between the 3 types, 4 things to check, and how to work out the cost per battery, so you can decide which one to buy.
First, Understand the 3 Common Types of Household Batteries
| Type | Features | Who it is for |
|---|---|---|
| Zinc-carbon battery (manganese dry cell) | The lowest price, common in basic packs, and just right for items that use low to medium power. In high-drain items, the charge drops faster, and the use time is usually shorter than alkaline | Low-power, rarely used items such as remote controls, clocks, doorbells, and a flashlight used now and then |
| Alkaline battery | The price per battery is usually higher than zinc-carbon, and the capacity is larger. In high-drain items it usually lasts longer, and it also suits items that stay on standby for a long time | Items that use more power or are used often, such as toys, electric toothbrushes, camera flashes, and microphones |
| Rechargeable battery (nickel-metal hydride) | You need to buy a charger separately and each battery costs more, but it can be recharged and reused many times. The voltage is slightly lower than an ordinary battery, so for some items you need to check that it is compatible, and it also slowly loses charge on its own when left unused | People who use them every day, in high-drain items, and are willing to buy a charger first |
No single type is "the best". It mainly depends on what it is used in, how often, and how much power it draws. For low-drain items that are not used much, such as a TV remote or a wall clock, zinc-carbon is usually enough. For high-drain items or items used every day, alkaline or rechargeable is a better deal. Consider a rechargeable only if you change batteries often and want to save in the long run. Before you buy, read the item's own instructions, because some items state the type of battery to use, and go by the item's instructions. This page only explains how to choose and is not product safety advice.
4 Things to Check When Choosing Household Batteries
| What to check | What to look at |
|---|---|
| Does the type match your use? | First think about what you will use it in. Low-drain items such as remotes and clocks can manage with zinc-carbon, while for items that use more power such as toys, electric toothbrushes, and cameras, zinc-carbon runs out quickly and alkaline is usually less trouble. Putting a more expensive battery in a low-drain item does not necessarily make it last longer |
| The right size | What is called size 3 (3號) in Taiwan is AA and size 4 (4號) is AAA. They are different sizes and cannot be mixed. Before ordering, check clearly whether it is size 3 or size 4 and whether it is the pack you want. Many shop pages list both sizes as options, and if you need both at home, you can buy them separately or choose a shop where you can pick either |
| Brand, origin, and where the label comes from | Some shop pages state the brand, model, and origin, and some only write "Japanese quality" or "imported". Labels on a shop page are mostly the seller's description, so before you order it is best to see whether the pack clearly shows the brand and model, and to check whether it is sold through a proper channel. We have not checked these labels one by one |
| Cost per battery and how long it lasts | Do not look only at the unit price. Work out "total price ÷ number of batteries", and then estimate how soon you will need to change them. In a low-drain item one battery may last several months, so the monthly cost is actually very low, while in a high-drain item a cheap battery may run out quickly and cost more. A big pack is usually cheaper per battery, but if you leave it too long without using it, it may expire, so think about how much you use |
How to Work Out the Cost per Battery So a Low Unit Price Does Not Fool You
Do not look only at "how much for one pack". Look at "total price ÷ number of batteries", and then work out how long they really last. As an example of the calculation: a pack of zinc-carbon batteries put in a remote control used every day may need changing every month or two, while the same pack in a rarely used clock may last more than half a year. How many batteries an item uses in a month, multiplied by the cost per battery, is the monthly cost. This is only an example of how to calculate, not a guarantee, and the real use time depends on how much power the item draws, how often you use it, and how it is stored. A shop may list different sizes, counts, and combinations at once, so before you order check the option you chose, and then work out the cost per battery so the figure is accurate.
Choosing by Item
- TV and air conditioner remotes — Low drain and not used very often, so zinc-carbon or alkaline both work, with size 4 or size 3 depending on the remote's model. If you use the remote a lot, alkaline usually lasts longer.
- Wall clocks and small electronic alarm clocks — Very low drain, so zinc-carbon is enough, and one battery usually lasts several months. Consider alkaline only for a clock placed too high to change easily, to lengthen the time between changes.
- Toys, electric toothbrushes, and handheld mini fans — Higher drain and used often, so zinc-carbon runs out faster, and alkaline or rechargeable is a better deal. For children's toys, check that the battery cover is fastened tightly.
- Flashlights and power-cut backup — Almost never used, but they must light when you need them. For spare batteries kept long term, we suggest storing them separately rather than leaving them in the flashlight, and checking regularly for leaks.

Quick Checklist Before You Buy
- What is it for? → Low-drain remotes and clocks suit zinc-carbon, and toys and electric toothbrushes that use more power suit alkaline or rechargeable
- Is the size right? → Size 3 is AA and size 4 is AAA, different sizes that cannot be mixed, so check before ordering
- Can you trust the label? → See whether the pack clearly shows the brand and model, and treat phrases like "Japanese quality" as the seller's description
- Want to know if it is a good deal? → Work out "total price ÷ number of batteries", estimate how soon you change them, and do not buy a big pack that will expire unused
- What do you do with them afterward? → Take used batteries to a collection point, and store spares separately and check regularly for leaks
Frequently Asked Questions
- What do size 3 and size 4 batteries mean, and can they be mixed?
- What is called a size 3 battery in Taiwan is AA, and a size 4 battery is AAA. They are different sizes, with size 4 thinner and smaller than size 3, and they cannot be mixed. Before you buy, check the battery cover or the manual of your item to see which size and how many it needs, and choose that size.
- What is the difference between zinc-carbon and alkaline batteries, and which should I buy?
- Zinc-carbon batteries cost less and suit low-drain items such as remotes and clocks. Alkaline batteries usually cost more each, but in items that use more power or are used often (toys, electric toothbrushes, and so on) they usually last longer. Neither is always better. It depends on the item's power draw and how often you use it, and you should go by the item's own instructions.
- Can I mix old and new batteries, or different brands?
- Generally we do not recommend it. Mixing old and new batteries, or different types or brands, can make the power drain uneven, shorten the use time, and make leaks more likely. When you change batteries in one item, change the whole set at the same time and use the same type.
- What should I do if a battery leaks, and how do I throw away used batteries?
- If you find a leak, do not touch it with bare hands, do not put it in your mouth, and keep it away from children. Wear gloves or wrap it in paper, and take it to a collection point as local rules say. Take used batteries to a collection point and do not mix them with ordinary trash. For items you will not use for a long time, we suggest taking the batteries out and storing them separately. If it gets in your eyes or your skin feels uncomfortable, see a doctor as soon as you can.
