 Battery capacity in Amp-hours is written as **C**.  This notation is most useful when talking about charging/discharging rates.
-Note:  most deep cycle manufacturer's rate capacity at C/20, due to Peukert effect.
+Note:  most deep cycle manufacturer's rate capacity at C/20, due to Peukert effect.  In other words, a 100Ah battery will deliver 100A with a 5A load.  See table at bottom for other load levels.

 If the manufacturer recommends max //discharge// (load) be 3C the rate should be at or below 600A (3x200). \\
-If the manufacturers says that [[electrical:12v:charging|Absorption stage]] is complete when charging current has dropped to C/100 or C/200 then the current to watch for would be 2A (200/100) or 1A (200/200).
