Types Of Laptop Battery
Currently there are three types of batteries commonly used for laptops: Lithium Ion ,Nickel Cadmium, and Nickel Metal Hydride.
Lithium Ion (Li-ion) This type is lightweight and performs better than the other types of batteries.. These batteries have very high energy densities (almost twice as that of NiCad batteries) .Li-ion batteries produce the same energy as NiMH but weighs approximately 20%-35% less. They do not suffer from the “memory effect“ like their NiMH and Ni-Cds. There’s usually a rapid-charging option with lithium-ion batteries, which is good when you’re in a time crunch.
These batteries are eco-friendly, user friendly .Their substances are totally non-hazardous .
Nickel Cadmium (Ni-Cd) Nickel Cadmium (Ni-Cd) batteries is the oldest battery type of the rechargeable batteries,but today they are out of date.They are heavy and very prone to the "memory effect". When recharging a NiCd battery that has not been fully discharged, it "remembers" the old charge and continues there the next time you use it. Which permanently reduce your battery's lifetime, even make it useless. To avoid it, you should completely discharge the battery and then fully recharge it again at least once every few weeks. Even so NiCads offer great performance, and they dominated the portable power storage market until the better battery technologies came along. The radioactive materials it contains cause severe problems during their disposal and hence is environmental unfriendly.
Nickel Metal Hydride (Ni-MH) Nickel Metal Hydride (Ni-MH) batteries are the cadmium-free replacement for NiCad. They are less affected by the memory effect than NiCd. And NiMH battery is longer lasting than a NiCad .However, they have problems at very high or low room temperatures. And even though they use less hazardous materials , they cannot be fully recycled yet.
There used to be the Nickel Cadmium batteries which had low energy densities but high discharge rate and long life. But they were soon replaced by the Nickel Metal Hydride batteries for being environmental unfriendly.
To extend the life of a NiMH battery, I recommend fully discharging it every so often, after you use, drain, and recharge the NiMH battery about few times, completely drain and recharge it again.
After knowing the difference of the 3 type laptop battery ,here comes with the maintenance tips
1. It is recommended that you fully charge and discharge the new battery two to four times to allow it to reach its maximum rated capacity. Generally you can perform an overnight charge for this. And keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks.
2. It’s ok to Keep your devices plugged in while you’re busy with it .But the heat do damage the battery. An overworked processor is the main reason that your device becomes unbearably hot at times.
3.Keep the battery connect with the laptop after a full charge won’t damage your battery.
Today’s computer (and smartphone) batteries is that they’re designed with internal circuits that stop the charging process the second it’s full. These systems prevent the battery from overcharging. Nowadays, the only way for batteries to overheat is when the charging system itself is dysfunctional.
4.Li-batteries last longer if you never let them drain fully.
5.Batteries should be stored in a discharged state since they can self-discharge and may become inactive after a long storage period. High humidity and temperatures can cause the battery to deteriorate, so these should be avoided during storage.High temperatures may result in damage to the battery or cause fire or burns.
