<p class="p">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 shouldn't expect a big difference.</p>
<div class="list"><div class="inner"><div class="region"><ul class="list">
<li class="list"><p class="p">Don't let the battery run all the way down. Always recharge
    <span class=" em">before</span> 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.</p></li>
<li class="list"><p class="p">Heat has a detrimental effect on the battery's charging efficiency.
    Don't let the battery get any warmer than it has to.</p></li>
<li class="list"><p class="p">Batteries age even if you leave them in storage. There's little
    advantage in buying a replacement battery at the same time as you get the
    original battery - always buy replacements when you need them.</p></li>

<div class="note" title="Annotazione"><div class="inner"><div class="region"><div class="contents"><p class="p">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.</p></div></div></div></div>
