<title>Get the most out of your laptop battery</title>

As laptop batteries age, they get worse at storing charge and their capacity

gradually decreases. There are a few techniques that you can use to prolong

their useful lifetime, although you should not expect a big difference.

<list>

  <item>

    
Do not let the battery run all the way down. Always recharge

    before the battery gets very low, although most batteries have

    built-in safeguards to prevent the battery running too low. Recharging when

    it is only partially discharged is more efficient, but recharging when it

    is only slightly discharged is worse for the battery.

Heat has a detrimental effect on the charging efficiency of the battery.

    Do not let the battery get any warmer than it has to.

  </item>

  <item>

    
Batteries age even if you leave them in storage. There is little

    advantage in buying a replacement battery at the same time as you get the

    original battery — always buy replacements when you need them.

  </item>

<note>

  
This advice applies specifically to Lithium-Ion (Li-Ion) batteries, which

  are the most common type. Other types of battery may benefit from different

  treatment.
