Batteries and Their Types

Batteries may be classified into two types, one based on application and the other based on the process of construction. Application batteries are automotive, marine or deep cycled. By the process of construction, batteries can be flooded, gelled and AGM.

A deep cycled battery has the ability to harness solar energy as a backup source. This type of battery has a dry mechanism or starve electrolyte. A majority of the deep cycled batteries are made of fiberglass mat with a high-density compound of sulfuric acid inside.

Construction-type batteries flaunt a standard, removable cap. They are referred to as being maintenance-free. They also have regulated, sealed valves. The valves contribute to regulated pressures.

A DC battery

Direct current is a type of electricity. In a DC battery, the electric charge always travels in a uni-directional way. This may also cause an imbalance to the electric charges.

DC batteries are sealed with electrolyte and several layers of metal. The electrolytes carry positively charged electrons.

The battery’s output terminal sports both positive and negative poles. When these poles are connected with each other, the current flows between them.

Sealed batteries

A Sealed battery is usually maintenance-free and non-spoilable. It has lesser corrosion rate as there is no liquid inside. It also has low self-discharge and cracking amperage.

Sealed batteries can supply both reserve and starting applications. They are generally more competent and have a longer life. Sealed batteries appeal to the price-conscious user and are frequently used to cut costs.

Deep cycle batteries

Deep cycle batteries generally have a heavy, thick plate made of lead. The plate aids the battery to withstand a deep charge. It is slower to dispense a charge when compared with a starter battery. It has a longer life span due to the thick plates. It is also used to initiate combustion in engines.

Starting batteries

A starting battery has multiple thin plates as opposed to a single plate, which enable it to release a comparatively larger amount of electric current quickly that too within a short time period. It is used in engines for combustion to continue.

A disadvantage when using a starting battery is that it cannot be deeply discharged. Most starter batteries get spoilt when nearing a complete discharge.

Gel cell batteries

Gel cell batteries are also known as gel batteries. They have a silica gel inside which makes the acids harden into a solid. One benefit of using these batteries is that they don’t drip acid even when broken.

These batteries are slow to charge and cannot cope up with a conventional automotive charger. They also have a limited current flow and tend to get damaged easily.

AGM batteries

AGM or ‘Absorbed Glass Mats’ type of batteries are the new sealed type batteries used between plates. The plates are made of a fine fiber of Boron and Silicon glass. These types of batteries have the same features as that of gel type batteries, but can handle more electric discharge.

Even when broken, these batteries do not spill out, as the glass mats hold the acid and electrolytes together. As there is no liquid in the inner layer, it is also safe from damage caused due to spilling.

Product Overview:

Within this Alienware Area 51 M7700 Laptop you will have the ability to streamline your productivity and if you are a gamer, then you will absolutely fall for this laptop computer. Like most computers, this laptop comes with downfalls, which I will discuss further down.

To start off this laptop comes with the Intel Pentium Processor, which allows you to have a stable platform to perform all of your computer tasks. Whether you are into intense gaming or just want a fun and fast laptop to do your daily tasks, this laptop is well-capable of doing that.

The screen for this laptop is a massive 17-inches, with a screen resolution of 1400 x 900. This screen has been developed to provide you with real-life details that are fluid in their motions and full of color and depth. Again, this laptop was designed for gamers, so you can believe that the screen looks breathtaking.

The graphics processor this laptop is the NVIDIA GeForce Go 6800, which has been deemed as a very stable graphics card. While this isn’t the most advanced graphics card that is currently available, it can definitely compete with some of the other high-performance computers on the market.

Okay, now to discuss the downsides to this laptop The hard drive for this laptop is very small, only 60GB with a run speed of 5400RPM. If you are using this laptop solely for online and offline gaming purposes then you will find this hard drive to be sufficient, but if not, then you will be very disappointed with its storage capacity.

You will also be able to burn/read CDs and DVDs at variable speeds. There is also a 7-in-1 memory card reader, which will allow you to easily access and upload your digital photographs and movies, however, due to the hard drive capacity, I wouldn’t recommend uploading movies.

Price and Availability:

This Alienware Area 51 17-Inch M7700 Laptop can be purchased online and at select retail stores for an average price of $1,200.
