+description: |
+  Samsung SDI (Samsung Digital Interface) batteries are all different versions
+  of lithium ion chemistry devices used for mobile phones, laptops and other
+  portable electronics. The batteries are adapted to a specific product and
+  the physical restrictions make it impossible to use another battery with the
+  product, so product device trees can specify these batteries. Operating
+  systems should determine hardware characteristics of the batteries from the
+  compatible string.
