We all know the battery constraints on any laptop; you can work on it for maximum 2 to 2.5 hours with a fully charged battery. So to solve this problem, laptop manufacturers have developed something known as an external laptop battery. Now this battery can definitely increase your laptop’s usage time but how long will it last?
The lifespan of any external laptop battery depends on the type of batter and its capacity. The higher the capacity, the higher the lifespan. And it also varies from brand to brand. More expensive external batteries are known to have a lifespan of 7 to 10 hours while the less expensive ones will shell out a couple of hours of battery life.
Apart from these factors there are many other parameters that can alter battery life. Eventually all rechargeable batteries wear out with time. Its performance will decrease over the years. Normally the expected time for batteries to slow down is after two years. But if the battery is extensively used, it could be seen in 18 months or so.
Most good quality external laptop batteries will perform well up to 1000 charge-discharge cycles before its time to dispose of them. But you can follow few tips to increase its lifespan:
Using the laptop continuously will increase the temperature inside the machine which reduces battery life. So it’s advisable to give your laptop some rest, at least to cool it off.

Disable start up items. This will reduce the usage of virtual memory which will result in increasing the lifespan of your external laptop battery.
Finally, use your laptop as needed and avoid over-usage. This will significantly increase battery life.
All rechargeable batteries die out sooner or later, depending on the usage. But by following the above mentioned tips you are sure to increase your battery life to a great extent. It’s always advisable to keep a spare external battery handy in case the one in use becomes obsolete.
Laptop users can choose to use the external batteries till it completely drains out. But it’s advisable to keep a replacement battery handy when the battery in use is only 30% away from completing its original run time. Batteries will perform well only if you take care of its usage and do not over-stress the device. Like any electronic device, external batteries too need proper care and justified usage.
