+===== specs =====
+  * Ah (Amp-hours) - the rated [[electrical:12v:battery_capacity|capacity]] of the battery
+  * Wh (Watt-hours) - like Ah above, only multiplied by the nominal voltage.
+    * 100Ah of lead is 1200Wh (100Ah x 12.0v).
+    * 100Ah of LiFePO4 is 1280Wh (100Ah x 12.8v)
+  * cycles - the number of times the battery can be charged and discharged before being considered End Of Life.((EoL is typically considered the point where the battery can no longer produce 80% of its rated output)).    Cycles are usually calculated using a particular [[electrical:12v:battery_capacity|C rate]] and [[electrical:depth_of_discharge|depth of discharge]].
+    * Lead is typically rated at the 1/20th the current as Ah (5A for a 100Ah battery) down to 50% DoD.
+    * LiFePO4 is typically rated at the 1/5th the current as Ah (20A for a 100Ah battery) down to 80% DoD.
+    * both maximum and recommended charge/discharge currents are given [[electrical:12v:battery_capacity|in C]].
