Laptop Battery Guide

A lot of people these days are interested to find out what is the average laptop battery life. This is interesting to know so that you can compare your own batteries life to others. Some batteries will perform much better than others under different circumstances and it also depends a lot on the quality of the battery that is in the laptop. If talking about how long a battery will last between charges then older laptops had an average battery life of around one to one and a half hours but these days it is much more common for batteries to run for much longer. High quality, expensive laptop batteries will run for up to 8 hours if used on low settings with no external plug ins operating and there is even a new type of laptop that will run for up to 19 hours without a recharge.

Average Laptop Battery Lifespan

The time before a battery needs to be replaced is also quite variable and also depends on how the battery is treated over its lifetime and what conditions it is used under. Batteries that are well looked after and used in non extreme conditions should last up to 3 years but if they are used very frequently and in hot conditions then the lifespan can be as low as 6 months.

Increasing Your Laptop Battery Life

Some of the factors that will influence your laptop battery life between charges include how powerful the laptop is, the more powerful the less time out of each charge, what features does the laptop have enabled (such as external hard drives, wireless Internet etc.), and what the power settings are on the computer. If using Windows for example, the power saver setting can be enabled that will greatly increase the amount of time that you will get out of each charge. This will dim the screen of the computer and slow time the response time of the system but it means that if you really need to use your computer and do not have access to a power source then you will get more time before it needs to be recharged.

If you want to increase the actual physical lifespan of your battery then it all depends on what type of battery you have. More information can be found on this page about laptop battery life.
