Battery charger comparison 2018

Purchase advice for the battery charger comparison or test 2018

  • Battery-powered batteries can cycle between 100 and 1,000 charging cycles, saving you money and the environment. To recharge it, you need a battery charger.
  • If you have many different battery types in the household, we recommend a universal charger that offers the greatest flexibility, but slower charging. One-type or quick-charging devices are more timely at the finish. If you do not have a power outlet, a USB charger is an option.
  • Make sure that the charging current of the device is not significantly higher than the current that can store the battery, otherwise it can quickly overload, which harms the battery.

Battery charger comparison 2018: 2018

Many mobile electrical appliances draw their energy from batteries. At the same time, their biggest drawback became obvious as they flourished. For a long time disposable batteries dominated the market, which was costly and not environmentally friendly despite recycling. With the market launch of the rechargeable batteries, the biggest criticism was effectively nullified. Up to 1,000 charging cycles can pass through good battery batteries.

A rechargeable battery charger is good for filling them with new electricity over and over again. In our 2018 Battery Charger Comparison, we explain the difference between the various charger types and the various features that allow you to choose your own personal battery charger test winner.

1. Save costs and protect the environment - The battery charger and its advantages

Calculate battery charging time

How long a battery needs to be fully charged can be calculated with a simple formula: divide the battery capacity (in mAh) by the charging factor of the battery charger (mA) and multiply that by a factor of 75.
Example: (2000: 800) x 75 = 187.5 minutes or approx. 3:08 hours.

A battery charger is a good investment for you for several reasons. Although the initial cost of rechargeable batteries are initially higher than disposable batteries, but can Depending on the quality, rechargeable batteries run between 100 and 1,000 charging cycles. It quickly becomes apparent how quickly the whole thing will have a positive effect on your wallet.

Although Stiftung Warentest has not yet carried out a battery charger test, this does not stop you from looking for certain categories when looking for the best battery charger for your needs. If you have a high consumption of rechargeable batteries, you should buy a battery charger that can supply as many batteries as possible at the same time, In addition to models that can only hold one rechargeable battery, there are also those that can accommodate four, eight or even twelve batteries.

The charging current that flows also determines how fast charging can be completed. This is given in milliamps (mA) and can be between 300 and 1000 mA, In addition, it is interesting if the charger is designed for one type of battery or limited to certain sizes and whether it can charge different types at the same time.

Dispose of properly: Still far too many batteries end up in the normal household rubbish for the sake of consumer convenience or ignorance. But they do not belong there! Their ingredients are corrosive acids and require special treatment in recycling, To help with this process, dispose of used disposable batteries or defective rechargeable batteries best in hazardous waste or in collection box stores.

2. From Universal All-Rounders to USB Specialists - Overview of Charger Types

Manufacturers have launched several types of their brands that offer different characteristics that are attributed different importance in different battery charger tests. So that you can decide better on an execution, we present them individually in our purchase advice:

Universal charger

The all-rounder among the battery chargers offers you the greatest variety in charging different battery types, Whether AAA microcells, AA-Mignon, D-mono cell or 9 volt block - the universal charger is compatible with different batteries and can supply them with electricity at the same time.

You have to cut back on two aspects. On the one hand, each type of battery is not charged as effectively as a charger specifically designed for that type. On the other hand, overcharging can occur if you charge several different batteries in parallel in one device. Chargers with processor control are rarely found which recognizes the respective charge level and accordingly the charging for this battery then terminated individually.

A-type charger

As the name suggests, the one-type charger can not keep up with the variety of universal chargers, but is instead only designed for one battery type. In the case of AA batteries, it may happen that it can also accept AAA batteries. Again, there are variants with and without processor control.

Since they are so clearly set to a particular battery form, they can load them more effectively, So if you know that you do not use D or 9V batteries in the home, a model is the better choice.

Quick charger

If you do not want to waste any time and want to recharge the rechargeable batteries in the shortest possible time, you can buy a quick recharger. It allows a recharging time of about half an hour and works for it with a very high charging current.

However, this has the negative consequence that the batteries can not reach the maximum number of charging cycles that they could actually go through.

USB Charger

If you do not have a free outlet within range, but you can use a computer with USB ports as the power source, a USB charger is a good option. It draws the power that it gives off to the rechargeable batteries via a USB cable.

However, since the amount of electricity transferred, at least for USB 2.0 ports is less than the power outlet, it also affects the duration of the charging process.

Overheating heat: In addition to the aforementioned processor control, which prevents overcharging, there is another factor to consider, which you should keep in mind. During the charging process heat is generated and, depending on how much power is supplied, this temperature also rises. The mA indication is for batteries of great importance, because if the mA number of the battery charger is significantly higher, there is a risk of overloading and damaging the battery.
