A second laptop battery may extend the your laptop’s battery life. While your primary battery gets discharged, insert your second battery to keep your laptop running.

One thing that you probably ignored while you bought your notebook was obtaining a spare battery. The item is usually a must for the person who wants to work on the road and in the remote location where there will be a long time to be spent to reach the power socket. So, before you start to use the spare battery, make certain that it is fully charged.

If your notebook has some kind of quick-swapping ability, while the power becomes low, you are able to just eject the original main battery of your laptop and quickly insert your spare battery. But be certain that your laptop could survive such a exchange before you attempt to do it! Make a test swap in the non critical situation, you just need to be certain.

If your notebook does not have the capacity to hot-swap laptop battery, just turn off your laptop while the original battery is almost used out. Remove the old one, insert the fresh battery, then turn on the laptop again. Bear the following things in mind:

*Label batteries with one Sharpie so that you will not get the two batteries confused and insert the dead battery accidentally.

*If you plan to pull this trick often, obtain a laptop which supports hot-swapping battery in the first place.

*You may buy the spare battery from your dealers or from the stores which sell extra batteries.

Be wary of the generic battery! Always try to buy a battery that is approved by manufacturers for your notebook.
