Battery Chargers
The smart battery chargers in this category are suitable for charging AA pencil and AAA micro battery cells. Depending on the type, the chargers can also charge other battery sizes and standards, such as NiMH and Li-ion batteries. Some models also have a battery regeneration function, which can improve the capacity of cells that have been in use for a longer period of time. Chargers provide information on the charging or regeneration status via LCD or LED display. The DND Telecom webshop offers battery chargers from GP, TechnoLine, XTAR and other brands. Read more...

What you need to know about battery chargers
By using these types of devices, we are not only protecting our wallets, but also our environment. The battery chargers available in the DND Telecom webshop are typically used to charge 1 or 4 AA or AAA NiMH batteries. But the range also includes battery chargers that can be used to charge Li-Ion / IMR / INR / ICR batteries. These smart battery chargers have useful and essential features such as overcharging or overheating protection. The professional battery chargers also have their own LCD display to show useful information such as capacity, time elapsed from charge and can also detect and display faulty batteries.
What types of batteries can be charged with the battery charger?
Rechargeable battery chargers or universal charging adapters can charge many types of batteries, but not all types. Therefore, it is important to carefully consider what kind of battery you want to charge and whether the battery charger you choose is suitable for it. The chargers available in the DND Telecom webshop can be used to charge 1 or 2 Li-Ion rechargeable mini batteries of type 10440, 14500, 14650, 16340(RCR123), 17335, 17500, 17670, 17670, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22650, 25500, 26650, or 1 or 4 AA or AAA NiMH batteries.
What size and type of batteries are these mini battery chargers suitable for?
The battery chargers available in the DND Telecom webshop can be used to charge NiMH or rechargeable Li-ion / IMR / INR / ICR batteries.
How often do batteries need to be changed and how long does it take to recharge them with these battery chargers?
If you put batteries in the battery charger that are discharged, the device will not need more than two hours and you can reuse our rechargeable mini batteries. Of course, if you put batteries that are not fully discharged in the charger, this time interval will be much shorter.
What safety features does the battery charger have?
Choose a battery charger that has an LCD display. Why is this important? It allows you to keep track of where the charging process is at without having to do anything else. But the device also has a charge level indicator so you can see when charging is complete. But before you buy your charger, ask if the battery charger you're considering has a fast-charging function, which allows you to recharge your batteries in less time.
This way we can use them faster afterwards. It's also worth paying attention to whether your charger automatically switches itself off. This is important because it stops charging when the batteries are fully charged. This protects them from overcharging and extends their lifetime. There is one more important detail to look out for, and that is the reverse polarity protection function.
What voltage and amperage can battery chargers charge?
Battery chargers only need a low input voltage of 5 V to provide sufficient power for the batteries inserted.
Is the battery charger compatible with different brands and types of batteries?
When looking at the compatibility of our rechargeable batteries, we should not look at who made the battery, but at the type of battery we are dealing with. Because not all rechargeable batteries can be recharged with, for example, the universal charging adapter. The old NiCd batteries are rare and few manufacturers offer this type of battery, so not all battery chargers support charging them. NiMH batteries are currently the most common. But Li-Ion rechargeable mini batteries are also very popular. It is therefore extremely important to pay attention to what batteries you have and which battery charger you are looking for.
What type of connector does the battery charger have?
Battery chargers offer two charging modes. One option is via a USB connection, and the other is to connect them to the mains using a mains adapter. This allows a high degree of flexibility in use.
