Best rechargeable batteries: A complete buying guide

All you need to know before buying a great rechargeable battery

Picture of a rechargeable battery

The best rechargeable batteries are long-lasting and quickly recharge for the utmost convenience. However, not all rechargeable batteries are made equal, so it’s important to choose reliable batteries otherwise it may defeat the purpose of buying them. Check out the buying guide below for how to choose the best rechargeable battery:

What are rechargeable batteries?

Rechargeable batteries are a type of battery that can be recharged to allow frequent reuse. They are available in several formats, including AAA, AA, C, D, and 9V, and can hold a charge for several hundred hours, which is significantly longer than disposable batteries.

Why should you buy a good rechargeable battery?

A good set of rechargeable batteries is a great investment if you have many electric devices that require batteries. As they can be recharged, these batteries have a significantly longer lifespan than disposable batteries, meaning you may end up saving more in the long-term by recharging rather than buying new. Rechargeable batteries are also more environmentally friendly than disposable batteries.

How to choose the right rechargeable battery?

It is important to choose the right rechargeable batteries to ensure they perform as best as they can. Here are some things to consider that will help you to choose the best rechargeable batteries:

  • Capacity: This refers to the amount of electric charge the battery holds, so the higher the capacity the longer lasting the battery. Battery capacity is measured in milliamp hours (mAh). This information is typically found on the back of the packet. So be sure to check and see but remember that certain devices drain batteries faster - if this is the case try to buy as high a capacity as possible. For instance, a range between 1,300 and 2,900mAh being a good capacity for AA batteries, while anything from 500 to 1000mAh is suitable for AAA.
  • Pre-charge: A pre-charge battery is a great option as it allows you to use it straight from the package. As recharging batteries often takes a few hours, this is very convenient if you have an urgent need for the batteries.
  • Charger: Not all rechargeable batteries are sold with a battery charging device, so you may need to buy this separately. This is required to recharge batteries using a mains power or USB outlet - so make sure you have one available. Consider what battery sizes the charger takes too, with many capable of recharging several types at the same time.
What is the best kind of rechargeable battery in the UK?

There are a few options when it comes to types of rechargeable batteries, with each one offering their own pros and cons.

  • Nickel Cadmium (NiCd) Batteries: Among the cheapest rechargeable batteries, they offer quick charge times and are relatively durable, although their memory effect does make them less efficient in some instances. So, it’s often a good idea to drain most of the battery before recharging.
  • Nickel Metal Hydride (NiMH) Batteries: A great rechargeable battery, it comes with a much larger capacity than most nickel-cadmium batteries and has no memory effect, making them longer lasting too. As a result, they have mostly replaced NiCd batteries in many formats, including AA and AAA. It’s important to not let the battery completely drain before charging, as this might cause lasting damage that decreases the battery lifespan.
