Black and Decker NS 118 Battery Charger
The following table shows the different types of batteries that are available from Black and Decker. You will see that there are two kinds of batteries: Lithium Ion (Li-Ion) and Nickel Metal Hydride (NiMH). Each one has its own advantages, disadvantages, characteristics, safety features etc.
The lithium ion battery has a higher energy density than the nickel metal hydride battery. However, it takes longer to charge. Li-ion batteries are used in many electronic devices such as cell phones, laptops, digital cameras and other consumer electronics. They have a shelf life of 10 years while NiMH batteries last up to five years.
Battery Type Energy Density Weight Capacity Lithium Ion 3.7 Wh/L 364 g 35 Ah NiMH 2.8 Wh/L 306 g 25 Ah
In addition to these two types of batteries, there are also other types of batteries such as lead acid, hybrid and others. There are various manufacturers producing different kinds of batteries and they all have their pros and cons. Black and Decker is one of the most popular manufacturers when it comes to power tools.
Black and Decker Lithium-Ion Battery
When compared to other power tool manufacturers, Black and Deckers tools are found to be more powerful for a longer period of time. This is mainly because of its battery technology. Black and Deckers cordless tools have high energy density which means that their batteries can produce higher power.
Also, they are lighter in weight and have better heat management.
The battery chargers are designed in a way that prevents overcharging. Once the battery is charged, it reduces the charging current to a certain level preventing it from overcharging and heating up. If you try to charge a lithium-ion battery when its already fully charged, it may get damaged.
So once the battery is charged, the charger reduces the charging current. This feature helps prevent battery damage and helps increase the life of the battery.
Black and Deckers batteries are composed of several lithium-ion cells. If you use the battery when its partially charged, then only that particular cell is going to get damaged. However, if all the cells are connected in a series, then the whole battery gets damaged even if only one cell is damaged.
To prevent this from happening, Black and Decker has designed their battery such that if any of the cells malfunction then that particular cell will stop sending current to the rest of the cells. This feature helps to increase the life of Black and Deckeres battery.
Nickel -Metal Hydride Batteries
Nickel-Metal Hydride batteries are cheaper than a lithium-ion battery of the same size. However, these batteries do not last as long as a lithium-ion battery, so this is a major disadvantage of this type of battery. In addition to this, the battery cannot be charged up to 1000 times like a li-ion battery can.
This means it has a shorter life span.
In order to prevent the battery from getting damaged, the charger has an inbuilt protection mechanism. If the battery is hot due to overcharging then the charging current gets reduced automatically. Also, another protection mechanism is that if the battery is not charged to its full capacity within a stipulated time (usually 24 hours), then the charger stops charging.
This feature helps to increase the life of the battery.
If you want to increase the life span of your power tools (chances of battery failure decreases as you keep using the product), then always use a battery that is fully charged. Also, don’t leave the battery on the charger for more than 24 hours as it may lead to battery damage.
Dimension wise, both types of batteries are similar in size and weight. However, a lithium-ion battery is safer to use around water.
