How Can I Extend the Life of My Laptop Battery?

If you are wondering how to extend the life of your laptop battery, here is some advice for you.

Life of a Laptop Battery

Laptop batteries usually last around four years and then it comes time to buy a new one.  This depends upon how often you use your laptop and also how often you charge your battery.  If you use your laptop when traveling a lot it will reduce the life of the battery and it may only last two years.  Batteries generally self discharge at a rate of about 1% per day.

Generally when charged a laptop battery should last 3 to 5 hours.  There are ways of making sure that you extend the lifetime of your laptop battery and these are provided below.

How can I Extend the Life of my Laptop Battery?

Ensure Full Charge from the beginning

When you first get your laptop ensure that you fully charge your laptop before using it this is important to ensure that the battery lasts to its full extent.

Don’t use your Laptop on a Soft Surface

While it is tempting to use your laptop on your lap or bed – this is part of the flexibility of laptops, it will not do your battery any favours.  On a soft surface the laptop fan cannot circulate air properly and you may overheat the machine which will reduce the life of the battery.

Don’t use your Laptop with the AC Adaptor frequently

If you do this, in the longer term it will result in your laptop battery having a chemical memory which reduces the life of your battery.  Make sure that you only charge your laptop battery when it needs to be charged, don’t leave the laptop batter plugged in all the time.

CD and DVD Drives

Spinning CDs and DVDs use a lot of battery power, remove these if they are not in use.

Unplug External Devices

Unplug any external devices that you are not using such as USBs, external speakers and attached iPod.

Storing your Laptop

It is very important not to overheat your battery – don’t leave it in a hot car for example.  You need to store your laptop at room temperature as batteries hate heat.

Ongoing Use

Minimising screen brightness, closing Wi-Fi when not in use and shutting down unused programs will help extend your battery life.

Charging your Battery

Always let your battery get to a low charge before charging it, the lower the battery if when you charge it the longer it will last.  It is very beneficial to allow your laptop battery to die before charging it – this will ensure you have the maximum life out of your battery.  It is best to recharge your battery once a month.

Buying a New Battery

We recommend that your new purchase has the same specs as your previous battery – that is the same capacity which is the mAh rating and also the same chemistry.
