Buying a new battery charger? Whether buying one for the first time or simply upgrading, it helps to know what features and functions are worth investing in.

What are battery chargers?

A battery charger is a device used to recharge batteries. Only rechargeable batteries are compatible with battery chargers, while certain types and sizes of batteries require specific battery charges. For example, rechargeable alkaline batteries use a different battery charger than lithium batteries.

Why should you buy a good battery charger?

The best battery charger devices are very useful, allowing you to easily recharge batteries, saving you the hassle of constantly buying disposable batteries. Portable charge banks are also great for anyone that uses mobile devices like smartphones and tablets, being able to recharge them without needing power from a plug socket or computer.

How to choose the right battery charger?

Finding the best battery charger can feel overwhelming when you don’t know where to start looking, so be sure to consider some of the following things before you buy:

  • Battery Size and Type: Traditional battery chargers are used for recharging secondary (rechargeable) AA, AAA, D, or 9-volt batteries, while portable battery chargers are used mainly for smartphones with ion batteries. So, it’s important to buy a battery charger that is compatible with the rechargeable batteries you have or need. For instance, a AAA battery charger cannot be used to charge AA batteries, while portable battery chargers only work on lithium batteries.
  • Charge Speed: The best battery chargers tend to offer the fastest recharge speeds, but they are also much more expensive as a result. Slower charge speeds usually mean a cheaper charger, and this can still be useful for overnight charging, so think about whether you need fast charge and if you are happy to pay more for it.
  • Capacity: When buying a battery charger for alkaline batteries, there are various capacities available, so consider how many you need to charge at any given time. For example, smaller battery chargers tend to recharge 2-4 batteries, while large chargers can fit as much as eight.
  • Indicator: A charge indicator is a great feature that shows you when the battery is fully changed. Some more advanced chargers come with a time indicator that tells you how long is left to charge the battery, while others can even indicate if the battery needs replaced.

  • Fast Battery Chargers: Designed to quickly charge batteries without causing any damage to their cells, they significantly reduce battery recharge time, making them very convienent. This does make them more expensive however.
