Battery Charger

- further categories

A battery charger is used in every aspect of life, from everyday household tasks to the most demanding industrial jobs.

While in our homes they are mainly used to charge our simple electronic devices, in industrial environments they often function as work battery chargers with much higher voltage and power.

What capacity batteries can be charged with our chargers?

When buying a battery charger, make sure it can charge up to at least 800 mAh. This capacity will allow you to charge many energy cells to more than 50 percent in 30 minutes. If the battery can handle higher charging currents, our charger becomes a fast charger, which will charge it even faster.

Use fast charging in moderation, however, as using it over a long period of time will put a strain on it. The DND webshop advises that if you charge your power supply slowly, you should go easy on it. What does this mean in numbers? A slow charge means a charge current of 200 mAh.

How long does it take to charge an average battery?

Battery charging times can range from a few hours to eleven to fifteen hours. In almost all cases, this depends on the battery charger. However, what is more important than speed is to keep an eye on the temperature of the energy cell while charging.

It should never exceed 45 degrees Celsius. Once the charging process is complete, wait about 15-20 minutes before disconnecting the cables. This will allow the gases generated during the charging process to dissipate and no sparks will be generated when the cables are removed.

What you need to do to keep your battery for a long time?

All energy cells have a life expectancy estimated by the manufacturer. However, we must always take into account that this lifetime requires proper use and maintenance of the battery. Not only can various battery regenerators and conditioners be effective in this respect, but also quality battery chargers with useful features such as overcharging or output short-circuit protection can greatly assist proper use.

What types of batteries can our chargers be used for?

Good to know that not all rechargeable batteries can be charged with a battery charger. The old NiCd energy cells have had their day and not all chargers support charging of these types of energy cells. NiMH batteries are the future. It is therefore important to be careful about the type of batteries you store at home. For which universal chargers can be used. Even before buying such equipment, we recommend that you read the product description carefully, even if the packaging shows batteries similar to ours, these may be Li-Ion batteries and not NiMH energy cells.

What other features should we choose a battery charger with?

Be careful to choose one that not only charges quickly, but can also power a particularly large number of battery types. In today's modern world, knowledge is one of the most important assets, and this is no different when it comes to charging energy cells. That is why modern battery chargers recognise their individual charge level. They even show us this on a display.

It is very important to buy a modern battery charger that recognises when the energy cell is faulty. Why is this so important? Because faulty batteries can explode while charging. That's why it's essential to have good fault detection. If there are children in the household, however, it is essential to take care of safety.

What to know about battery chargers

The battery chargers available in the DND webshop range are typically used to charge 2 or 4 AA or AAA NiMH (nickel metal hydride) batteries. These battery chargers are equipped with useful and essential features such as overcharge protection, which can significantly increase battery life over long periods of use. The professional battery chargers also have their own LCD display to show useful information such as capacity, time elapsed from charge, and to detect and indicate a faulty battery. And some types can also be used for testing and regenerating power supplies.

Features of gel battery chargers

This type of power supply is a sealed energy cell with a safety valve and a gel-like substance inside it that makes up the electrolyte between the cells. It has a longer capacity and lifetime than conventional types. They also require less care and maintenance and do not require the addition of water.

Gel batteries are used to power more serious equipment, so the device used to charge them also has more sophisticated electronics and safety features such as output short-circuit and overheat protection. A gel battery charger has advanced charging technology, and a work battery charger can also allow charging while driving.

About battery maintenance in brief

Regular maintenance of your power cell is as important as using it properly. The biggest threat to the life of a power source is so-called sulphation, which causes premature ageing and deterioration. This phenomenon is particularly dangerous for infrequently used vehicles, for example during a winter break. For this purpose, special battery regenerators and battery guards are used, which are a good solution to prevent this sulphate deposit and to remove it.

Battery regenerators significantly extend battery life

These types of regenerators can be particularly useful for less frequently used power sources, as they can be maintained gently even during an extended outage. Some types can also perform a charging function.

Benefits of battery guards

The most important function of these devices is to prevent deep discharging and battery drain. During operation, they automatically disconnect the equipment from the power cell if its voltage drops below a specified level. They ensure that there is always enough voltage to start the engine and protect against total discharge, which prevents, among other things, damage to the cells.

It is therefore important to always choose a reliable, quality product, whether for battery use or maintenance. With various maintenance equipment and the right battery chargers, you can do a lot to even multiply the lifetime of your power packs.
