Laptops are the necessity of the life these days because of its mobility. Well they are handy, easy to carry with you and all but what if it doesn’t have good battery? That’s true in Laptop Battery plays vital role. What if you want to use your laptop at the place where there is no ac mains power? Then you have only one option is that you must have enough battery life in your laptop.

Generally Laptop battery usually come in two types - nickel cadmium and nickel metal hydride. It’s good to know that to charge brand new batteries in cycles of fourteen to sixteen hours. The batteries should be allowed to cool down before recharging them because overcharging them will shorten their life.

Now if we think some technical points then ready access to chargers is important because nickel cadmium may suffer from a ‘memory defect’ and user may suffer with such problems if batteries are not fully discharged before recharging. A nickel cadmium battery should be charged only after it has been completely exhausted, otherwise the battery ‘thinks’ that it only has fifty percent of its original capacity and only uses half of its potential, thus increasing the time constraints of the laptop.

Laptop Batteries can be charged 2 ways, one, when the AC power is on for laptop. At that time a small flow of electricity runs to the battery which is called trickle charge. This will automatically recharge the battery after laptop is disconnected form AC supply. Second one is charging a battery with external charger.

These days Nickel cadmium batteries are most popular as they are long lasting and very efficient, and they perform more efficiently when they are fully discharged and then recharged. If a battery is used in a more piecemeal fashion then, occasionally fully discharging the battery before recharging it will enhance the productivity of the same. Some battery chargers do this automatically, but leaving the laptop during the night and recharging the battery in the morning can also invigorate the battery efficiently.
