When you buy a new battery for your laptop, you should know how to charge it properly so that it lasts you for a long time. Usually laptop batteries are lithium-ion batteries. Before you start using them on a full time basis, you should charge the battery completely three times and then discharge it completely three times.
By doing this, you ensure that the chemicals inside the battery are activated. In future, when you charge the battery, it will be able to charge optimally.In case you some how do not use the battery for 3 months or more, the above described procedure should be followed before you restart using the battery as normal.In case you are using new nickel-metal hydride (NiMH) battery, remember you should not charge the battery for too long or it will overcharge it and end up shortening the life of the battery.
However, it is important to charge and discharge the battery three times just like the lithium-ion battery to ensure that it has a long a life.Usually it has been seen that people who use laptops actually plug the laptop to the power supply. However, this is the wrong way of charging the battery. You should charge a battery once or twice a month. The battery should be charge fully at least 30 minutes before you start using it. In case you are going to use direct power supply, then it is best to remove the laptop battery.
This will ensure two things -- first, the battery since it is charged already will not discharge uselessly and second, it will ensure that the battery life is extended.Today, many of the latest computers have a fast recharge feature where you can recharge 90 percent of the battery power by charging it for around one hour. The balance 10 percent is recharged slowly. If your laptop has this facility, do use it. This helps to extend the life of the battery. However, do not recharge the laptop battery until it has less than 30 percent charge remaining.
