   * **A** - Amps (amperes).  A measure of electrical current.
-  * **AH** or **Ah** - Amp-hour
+  * **AH** or **Ah** - Amp-hour.  Example:  2.5A x 2 hours = 5Ah.
+    * Note that Ah is voltage-dependent:  5Ah at 12v is 60Wh, while 5A at 24v = 120Wh.  For this reason, Wh may be a more "portable" specification.
+    * the [[electrical:12v:battery_capacity|capacity]] of [[electrical:12v:deep_cycle_battery|deep cycle]] batteries is traditionally given in Ah.  Example:  a 100Ah battery will provide 100Ah from 100% to 0% DoD at a ~5A draw (C/20).
