Batteries are grouped in two ways. It is by application and by the process of construction. The major type of application batteries are the automotive, marine, and deep cycled. While the construction type are flooded, gelled and AGM.

The deep cycled types of batteries have a capacity for solar electric for back up energy. As for a technical description… Compared to AGM battery, this type has a starve electrolyte or dry mechanism. Most of the application batteries are made of fiberglass mat with a high-density compound of sulfuric acid, which applies a no excess liquid compounds.

Laptop batteries are rated by, Voltage (V) and Milliamp-hours (mAh). Voltage is the rate at which energy is drawn from the battery and Milliamp-hours Represents the capacity of the battery. The Milliamp-hour rating Corresponds to the run time of the battery. A battery with a high Milliamp-hour rating has a relatively longer run time than a battery with a Low Milliamp-hour rating.

Batteries with different Milliamp-hours can be used on the same laptop provided the voltage rating is the same. The voltage rating has to match that of the original battery or as recommended by the computer manual. Using a battery with a different voltage setting can seriously damage the laptop. The power ratings of most compatible/replacment batteries are higher than the original manufacturers’ batteries. This will not damage your laptop, in fact, it simply means that these batteries in many cases last longer than original manufacturers’ batteries. Ask the experts like PowerUp on compatible replacement laptop batteries.

Lithium Ion notebook batteries wear down because of two factors: 1) active usage in your notebook battery and 2) natural aging of the notebook battery. Both will wear down your notebook battery over time; the trick is to minimize their impact while still getting the performance out of your laptop battery that you need.

The most important thing to understand about laptop batteries is that they are always losing a small bit of their charge. The hotter the temperature, the faster notebook batteries loose their charge. So rule number one is: keep your notebook battery cool. Notebook battery manufacturers store their products at around 60F. (It doesn’t help to put them in the refrigerator, and you can damage a battery by freezing it.)

The second most important thing to understand about notebook batteries is that their capacity decreases with each cycle of charging and discharging (or usage). By itself, this is not surprising - but when combined with the previous point, it leads to a surprising conclusion.
