  • Alkaline batteries are economical and extremely popular

Alkaline batteries can be found in most houses as they are commonly used in many household items, such as torches or remote controls. Alkaline batteries are disposable, long-lasting batteries, but they do lose strength over time. They usually have a capacity rating of over 2,500 mAh, making them ideal for heavy use. These batteries have a shelf-life of anywhere between five to ten years, so you can keep them in your house without worrying they will expire.
  • Lithium batteries last up to 4x longer than other batteries

Lithium batteries are commonly used for devices such as fire alarms because they are capable of giving off a strong energy surge after a long period of low discharge. This means they will store their energy when they are not in use. The battery capacity of a lithium battery usually ranges between 2,700 and 3,400 mAh. However, this usually means they are a little bit more expensive than alkaline batteries. These batteries have a shelf-life of up to 15 years.
  • Alkaline batteries vs. Lithium batteries

When choosing between alkaline and lithium batteries, it is good to acknowledge that both are very efficient batteries. However, they do have many differences. Alkaline batteries are sold at great prices for the quality, while lithium batteries are more expensive but can last up to four times longer! Lithium batteries also don’t have as large a range of battery sizes as alkaline batteries. In the table below, you will see the range of alkaline and lithium batteries, as well as how their voltage can differ:

  • What does mAh refer to?

Often in battery descriptions, you may see ‘mAh’. For example, if a batteries’ capacity is 800 mAh. This means ‘milliampere hour’ and is the measurement for power over time. For batteries, this measures the energy charge and how long before the battery needs to be recharged. The larger the mAh rating on your battery, the more energy it can store. As a result, it is always best to choose a battery with a higher mAh if you want your device to keep its charge for longer.
  • Button cell batteries for your smaller devices

Button cell batteries can sometimes be known as watch batteries, or even as coin batteries. They are small, flat and round. These are usually used in wrist watches, clocks or even in your car keys. If you are not sure what type of button cell battery you need, you can always look at your device for some indication or check an instruction manual. We would advise you to be mindful of where you might leave these in the house, as they are small enough for children to swallow and are extremely dangerous if ingested!
  • Rechargeable batteries are really cost efficient!

Rechargeable batteries are a great addition to any household as some batteries can be recharged up to a thousand times! While you might pay a little bit extra initially for both the batteries and the charger, you won’t have to worry about buying new batteries every few months. Most rechargeable batteries can be fully recharged anywhere between one and four hours.

Common questions

Which battery has the longest lifespan?

Alkaline batteries' lifespan can last up to 30 hours depending on their usage. However, lithium batteries have a lifespan of about two to three years due to their low self-discharge. Button cell batteries can have a similar lifespan as a lithium battery, depending on the system power required.

Are 123ink own-brand batteries as efficient as other brands?

Our own-brand batteries are just as efficient as other brands. In fact, they have an extra long lifespan, so are more efficient than some other batteries. For example, 123ink own-brand AA batteries have a capacity of 2,900 mAh, whereas other brands have a much lower mAh. This means 123ink own-brand batteries will keep your device charged for much longer.

How do you dispose of batteries?

You can dispose of your batteries in any WEEE Ireland battery box, which are available throughout the country. Batteries are known to be harmful so it is important to dispose of them properly where possible.
