External Battery Charger for Laptops

Your laptop battery is a critical part of your notebook that requires proper care. Thus, it is necessary to charge a new battery in cycles of 14 to 16 hours. You should let the battery cool down before recharging it, as overcharging will shorten its life.

You can recharge laptop batteries in two ways. First, when the laptop is using AC power, a small flow of electricity runs to the battery. This charge will automatically recharge the batteries after the notebook is disconnected. Another way is recharging the battery with an external battery charger, or charging laptops externally. The batteries are fitted into the charger that is plugged into a standard electricity outlet.

Nickel cadmium batteries perform better when they are completely discharged and then recharged. Some battery chargers do this automatically, but leaving the laptop for a night and recharging the battery in the morning can also improve the battery's efficiency.

Laptop battery charger prices vary from $200 to $300 and typically have a year of warranty. Ready access to chargers is very important since nickel cadmium may have a “memory effect". You can face this problem if the battery is not completely discharged before recharging. In this case the battery “thinks" that it has only 50% of its original capacity and uses only half of its potential.

The Proper External Laptop Battery Charger

External laptop battery chargers are also used to charge external laptop batteries. External laptop batteries provide the users with almost 7 hours of uninterrupted power. The greatest advantage offered by external laptop batteries is that the user doesn't have to connect his laptop to a power source every now and then to recharge the conventional battery.

External laptop batteries are very affordable. A laptop owner can choose among Nickel Cadmium, Nickel metal hydride and Lithium ion batteries, the latter being the most efficient.

Some chargers presented at the market offer to charge batteries in 7 hours, but this can do a lot of harm to the batteries. Nickel cadmium batteries are likely to self-discharge, i.e. they may lose power when not being in use. Battery chargers solve this problem by providing the battery with a small charge that keeps the battery completely charged.

One feature worth spending extra money on is a charger control. An expensive battery charger has a microprocessor that switches the charger off when the batteries are completely charged. It can also recognize how much charge is originally in the batteries and only add whatever is needed. Cheaper chargers, on the other hand, charge batteries for a fixed length of time, which can overcharge the battery. The cheapest battery charger will cost less then $10, while top-quality chargers can cost up to $50.
