 Battery capacity in Amp-hours is written as **C**.  This notation is most useful when talking about charging/discharging rates.
-Examples:
+Note:  most deep cycle manufacturer's rate capacity at C/20, due to Peukert effect.
+===== Examples =====
 If you have a 200AH battery bank then C = 200AH.
 If the manufacturer recommends max //charging// at C/5 the rate should be at or below 40A (200/5). \\
-If the manufacturer recommends max charging at C((sometimes written as 1C)) the rate should be at or below 200A (1x200). \\
-Note: the **usual charge rate** for deep cycle batteries is C/10.  Sometimes manufacturers express that [[electrical:12v:charging|Absorption stage]] is complete((and therefore Float should commence)) when the bank is holding Vabs and charging current has dropped to C/100 or C/200.
+If the manufacturer recommends minimum charging at C/10 the rate should be at or above 20A (200/10). \\
 If the manufacturer recommends max //discharge// (load) be 3C the rate should be at or below 600A (3x200). \\
-Note:  most deep cycle manufacturer's rate capacity at C/20, due to Peukert effect.
+If the manufacturer 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).
