Lithium-ion batteries are widely used these days. They seem to be superior in almost every possible way like the car, mobile phone, the laptop computer and other cordless tools. It is so popular because it has many advantages such as no memory effect, pollution-free and so on. However, everything has two coins and it also has some shortcomings. Want to learn more about it, read our article here.
Firstly, when come to the advantage of the li-ion Compaq Presario CQ40 Battery, a summary as below:
1. The battery charge. These Lithium-ion batteries keep their charge better than almost any other material. Generally, a lithium-ion battery will lose only five percent of its charge per month without active use. A NiMH battery loses four times the amount at about twenty percent each month. Aside from holding the charge, lithium-ion Compaq Presario CQ62 Battery can also handle several hundred charge and discharge cycles.
2. Li-Ion does have an advantage over less exotic technologies in that you can store more power in a smaller, lighter package. But at a cost. Apart from the cells costing a lot more and needing fancy charge controllers to operate them safely(!), they're also quite fragile in the short term; and in the long term they don't survive for long.
3. It won't suffer from a problem known as the "memory effect" (where nicad batteries appear to become harder to charge unless they're discharged fully first). The reason is that lithium-ion Compaq 8510p battery don't contain cadmium (a toxic, heavy metal), they are also (in theory, at least) better for the environment-although dumping any batteries (full of metals, plastics, and other assorted chemicals) into landfills is never a good thing.
4. A small self-discharge. Room temperature, full power Li-ion storage 1 month self-discharge rate of about 10%, much lower than Ni-Cd of 25-30%, Ni-MH 30-35%.
Li-ion battery's Disadvantages:
1. Battery costs are higher than the normal batteries.
2. The lithium-ion battery will also degrade over time. The degradtion will happen when they leave the factory.
3. Also will come across the overheating issue and need to take good care of.
