Less Waste, More Money: The Best Rechargeable Battery Chargers

How would you like to help save the environment and some money in the process? It may be a slight contribution but it surely is useful. The benefits of rechargeable batteries are numerous but you won’t be able to use them unless you have a charger.

Nowadays, most household items, or even gadgets like a walkie-talkie for example, require AA batteries and most chargers are made for those however, some features might differ. With that being said, take your time to go through this article to understand how these devices work and which one is the right option for you.


What’s a Rechargeable Battery Charger?

Before getting into this, you should know that batteries can be disposable or rechargeable. As the name suggests, the former can be used once and then thrown away and the latter is “refilled” and reused over and over again.
The charger does that job but not all of these devices are compatible with just any battery.


How Does It Work?

Basically, the charger has several compartments in which you place the drained out batteries. It usually takes a few hours to fully refuel them once you plug the charger in.
Most products indicate when the charging process is completed so you could take out the batteries and put in others.


Different Battery Types

As mentioned earlier, not all chargers are compatible with all the batteries which is why it’s necessary to know which ones you use the most. You should also learn about the different types of batteries so you could buy the charger you need.


Important Features in an AA Battery Charger

As you could imagine, there are some specific features that should be included in the charger so you could make the best out of it. You should also know that some chargers are labeled as Smart since they include additional functionalities.


Docking Stations or Bays

In simple terms, this indicates how many slots are there in the charger. The more there are, the more batteries you can charge simultaneously.

Fast Charging

People look for this feature when they’re buying a cell phone charger so why not here as well? If this functionality is there, you might have to wait a few minutes instead of the usual few hours for the batteries to be fully refueled. Keep in mind that they might last for a relatively short period compared to the batteries that have been charged in the regular method.

Automatic Stop

The Automatic Stop is one of the features found in smart chargers and it deactivates the charger once all batteries are full.

Overheating Detector

In addition to the previously mentioned functionality, this is also a safety measure. If the charger or the batteries are overheating, the former will turn off instantly.

Trickle Charging

Let’s say that you have the Automatic Stop feature and the batteries are already at maximum capacity, leaving them there can drain their power. With Trickle Charging, the charger will make sure that these batteries are full whenever you decide to use them. This is also found in Smart chargers.

LCD Screens

Just like CB Radios, some models here have an LCD display. It may not be a necessary feature but it sure is helpful. Chargers that don’t have a screen might have a few lights that indicate the charging level, among other things.
