Why we test battery chargers?

A battery charger examined and found to be good by the comparison and still by the test, is a more or less practical accessory from the electrical field. This ensures that empty batteries can be quickly refilled with the necessary energy.

For rechargeable batteries, the battery charger, examined and found to be good by the test, is absolutely necessary and very important, because otherwise they can of course not be recharged so easily and safely.

How does a battery charger work?

How does a battery charger work in the test and comparison? A battery charger examined and found good by the test, is basically just the interface between the actual interface in your wall as well as the empty batteries. You then insert these appropriately into the charger as well as plug them into the wall socket.

With some models and products, you can also make further settings and adjustments for charging, but these are individually different and should therefore always be considered individually by you for your own battery charger, examined and found good by the comparison and still by the test. The charger then has suitable contacts inside, which ensure that the battery can be charged with the battery charger, examined and found good by the comparison and still by the test.

Advantages & Applications

As an alternative to batteries, rechargeable batteries have become increasingly popular today. The prices have fallen recently, while the technology at the same time has become better and better and more and more developed. Accordingly, the battery charger is also practical, examined, and found good by the comparison and still by the test. This is because you can usually recharge the classic rechargeable batteries over and over again without them significantly losing power. Many of the modern rechargeable batteries can be recharged with the battery charger, examined, and found to be good by the comparison and still by the test, well over 1000 times.

These relieve both the environment and your wallet. The constant purchase of new batteries is eliminated and at the same time they do not have to be disposed of again.

In principle, you can use the battery charger, examined and found good by the comparison and still by the test, so always where the normal batteries are used. Whether this happens in the private environment or in the office, of course, does not play a big role in the end.

Where to use CR123 batteries?

The CR123A battery is a lithium battery. It also fits into the category of photo batteries, because the CR123A was often used in old autofocus cameras. Their built-in photo flash and automatic film transport required a battery type with high power. Other uses include LED flashlights or wireless sensors in smart home systems and alarm systems.

How to find the best battery charger

However, finding the best battery charger can be difficult if you don’t know exactly how the different models differ. Therefore, you should consider the following things before buying:

  • Battery size and type: traditional battery chargers are used to charge rechargeable AA, AAA batteries. Therefore, it is important to buy a charger that is compatible with the batteries you are using. For example, the RCR123a li-ion rechargeable battery charger cannot automatically be used to charge AA batteries, while portable battery chargers often only work with lithium batteries.
  • Charging speed: The best battery chargers usually offer the fastest charging speeds, but they are also much more expensive. Accordingly, longer charging times usually mean a cheaper charger, but this can still be useful for overnight charging. So consider whether you need fast charging and whether you are willing to pay more for it.
  • Capacity: there are different capacities available when buying a charger for alkaline batteries. So consider how many you need to charge at any given time. For example, smaller chargers tend to charge 2-4 batteries, while large chargers can charge up to eight batteries.
  • Display: a charge indicator is a great feature because it shows when the battery is fully charged. Modern chargers even come with a time display to show the remaining charge time. Some devices can determine if the battery needs to be replaced.

There are these different types of battery chargers

The first basic decision you need to make when buying a battery charger is about the complexity of the model. Simply put, there are two types of battery chargers: simple and smart.

The simple ones are inexpensive, but they always charge at the same rate regardless of the charge status of the inserted batteries and do not monitor the process.

An intelligent battery charger, on the other hand, has a small processor that monitors the charging status and some other values and reacts when necessary. This makes overcharging or partial charging less likely. This is important in that rechargeable batteries last much longer if they are charged properly and gently. Those who use their battery charger frequently will then have to replace the batteries less often and save money in the long run.

FAQ – CR123 Battery Charger

How does a battery charger work?

A simple battery charger simply converts the current from the wall socket into a lower AC or DC voltage and charges the inserted rechargeable battery with a constant current. The problem is that the exact charging time can only be calculated if you know exactly what the charge level of the battery is.

However, this is hardly possible without a measuring device, which is why the batteries in a simple battery charger are usually overcharged or only partially charged, which destroys the battery in the long run.

Intelligent chargers with processor monitor and measure the charging status and prevent such overcharging. Consequently, these devices are more suitable for long-term and frequent use, even if the purchase price is higher.

Caution: a battery charger without analysis of the state of charge almost always leads to incomplete charging or overcharging. This damages the accumulators and significantly reduces the lifetime of the batteries.

How much power does a battery charger consume?

This question can hardly be answered in general, because it depends on the brand and model of the battery charger as well as the charging time and the capacity of the inserted battery. However, a battery charger is not a power guzzler in any case.

  • Battery Capacity: 700 mAh.

Special functions and accessories: Practical extras

In contrast to simple battery chargers that can only handle the basic functions of charging and discharging, high-quality and smart models are equipped with various special functions. Particularly helpful are small LED displays that give you detailed info on charging status, voltage (V), capacity (mAh), charging and discharging current, as well as charging and discharging duration. A discharge function is also beneficial, as fully discharged battery packs last longer in the long run.

These are also other practical functions:

  • Battery defect detection: The battery charger detects defective batteries by measuring the voltage.
  • Trickle charge: When the battery is fully charged, the charger can switch to a trickle charge to prevent overcharging. At the same time, a drop in the charge level is prevented.
  • Charging current adjustment: Enables particularly battery-friendly and safe charging
  • USB adapter: For charging the batteries via a USB cable – for example on a PC
  • Overcharge protection: Ends the charging process automatically so that the battery and battery charger are not damaged by too high a temperature
  • Quality and usability: The batteries themselves also matter

You can easily operate a battery charger even as a layman. However, pay attention to solid workmanship. Especially cheap devices often lack the important overheating protection or batteries are charged much too long. The quality of the rechargeable batteries also plays a major role: If you use inferior batteries, even a high-quality battery charger will be of no use.
