Batteries are perhaps the most important part of a laptop which is considered a necessary accessory. However, batteries, like any other gadgets can easily wear out depending on usage. Some batteries, if treated carefully can last for a year. In cases that we need to replace it, we also might need to know the basics on the best battery that can replace our original old one. The following are some of the most commercialized types of battery already available in the market:
1. Nickel-Metal Hydride Batteries
Also known as Ni-MH, these batteries are one of the most commonly used in the market. Ni-MH can provide inexpensive and efficient alternative to standard alkaline batteries and are available to almost all markets around the world. These kinds of batteries have been too popular that scammers are even able to produce fraudulent copies which are sold in the market to a cheaper price. Ni-HM however has a high rate of self-discharge. It may not be a problem when used after the first few months of manufacture but can cause big issues when stored fully charged and stored for a long period of time.
2. Lithium Ion Batteries
Li-ion Batteries have become widespread on the mid-1990s. It popularization has even expanded to developing cities. Jakarta, Indonesia, Singapore and Bangkok, Thailand are reported to be using Li-ion Batteries on all their laptop since it proves to be lighter compared to Ni-MH batteries which make them easy to be carried especially on crowded areas. A significant less discharge is also emitted by these types and can be considered safer to use.
However, there are also a few flaws in Li-ion batteries. Li-ions are prone to steep drops in total charge capacity over time, as deposits build up within the electrolyte, which inhibits ion transfer. In addition, high charge levels and elevated temperature result in a permanent loss of charge capacity, with up to 20 percent of the battery’s capacity lost if consistently kept at full charge and 77 degrees Fahrenheit.
3. Lead Acid Batteries
Perhaps never that much heard of, the lead acid battery is the most economical type for larger power applications where weight is of little concern. These types are also used in hospital equipment, wheelchairs, emergency lighting and UPS systems.
4. Lithium Polymer Batteries
Also known as LiPo batteries, these are more of an advanced version of Li-ion Batteries which uses solid polymer composite instead of using lithium-salt electrolyte in an organic solvent. This allows for a lower cost of manufacture, wider adaptability, and increased reliability and ruggedness.
