How to know how long you can use a laptop using it’s battery?
Max asked:
I’m gonna buy a laptop as I travel a lot but I won’t have a power source all the time so I’ll have to rely on it’s batteries. How will I know how much backup a laptop’s battery will provide? Do I just have to ask the seller or is there a better way?

check reviews online, there will be a time also on the box of the laptop or you can ask the seller however this time tends to be the max time, e.g. with screen brightness down, wifi/3g/blue tooth off so the battery life when doing stuff tends to be a hour or so less then they quote. Zac P

Depending on the type of laptop you are going to get and the battery that comes with it. Obviously, you should get a netbook or a laptop running on Intel Core 2 Duo Ultra Low Voltage processors. A 6 cell battery can power a netbook for about 6-8 hours and a laptop for about 5-7 hours. It also depends on your performance and screen brightness settings when on battery. The duration also varies according to usage as the more resource hungry the application the more power it consumes. Jun Yi

You can watch out the parameter of laptop battery capacity carefully.
Usually, the 4000mAh lasts 2hours, and 6600mAh lasts 3 hours.
If you think that’s not enough, you can get a external laptop battery such as dell inspiron 3000 battery on
It fit many popular laptop model and has 20000mAh.
It help your laptop lasts more than 10 hours, I think it’s enough. Shey
