<property name="battery-capacity" type="d" access="read">
<doc:doc><doc:description><doc:para>
The capacity of the power source expressed as a percentage between 0 and 100.
The capacity of the battery will reduce with age.
A capacity value less than 75% is usually a sign that you should renew your battery.
Typically this value is the same as
(<doc:ref type="property" to="Source:battery-full-design">battery-full-design</doc:ref> /
<doc:ref type="property" to="Source:battery-full">battery-full</doc:ref>) * 100.
However, some primitive power sources are not capable reporting capacity
and in this case the battery-capacity property will be unset.
</doc:para><doc:para>
This property is only valid if the property
<doc:ref type="property" to="Source:type">type</doc:ref>
has the value "battery".
