Today, despite the many new gadgets, laptops are very much used by people who moves around. People in sales and students needs the flexibility and freedom to do their school work anytime and just about anywhere. The problem is laptop batteries quickly lose its charge capacity, which leads to its replacement. The life span of a battery depending of course on how the battery is charged and discharged.
Here are the different types of batteries:
- Nickel cadmium (NiCad) is used by many electronic gadgets like cell phones, computers, old motherboards, and cordless phones. It is a highly known rechargeable battery that loses its charge faster when it gets older. This is called the “memory effect.” This happens when the battery thinks it is fully charged but is not. For example, the battery thinks it is 100% charged when in fact, it is just say 70% charged. This will result to shorter gadget usage. NiCad battery is made of nickel, in the form of Nickelic Hydroxide and Cadmium. Moreover, this heavy metal battery is not environmental friendly. If you are buying a new battery, look at the sticker. If it is not NiCad, then you do not have a problem.
- Nickel Metal Hydride Batteries (NiMH) appeared in the market in the 1980s to replace the toxic NiCad batteries. Instead of cadmium, it uses hydrogen as its active element. It contains no toxic metals that makes it environmentally friendly, and has a higher energy density. Its capacity is more or less two times the capacity of NiCad. NiMH is also receptive to “memory effect” but in a lesser degree. It is more expensive than NiCad but it is more superior and good for our environment.
- Lithium Ion (Li-ion) is the most common rechargeable batteries in newer laptops. Li-on is lighter compared to NiMH batteries and can provide an increase when it comes to the total charge capacity. This is good when it is crunch time. Compared to NiMH that automatically discharge 30% power in a month’s non-usage, Li-on loses 10% to 15% of its total power making it a better battery. This is the type of battery is ideal to be used in laptops and other mobile devices. The best part? It is environmental friendly.
