Battery capacity in Amp-hours is written as **C**. This notation is most useful when talking about charging/discharging rates. | **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. In other words, a 100Ah battery will deliver 100A with a 5A load. See table at bottom for other load levels. | C notation can also be used to describe the **relative amount of current** charging/discharging the battery bank. For example a 50A load on a 100Ah bank would be C/2.((technically C/20/2, but that form is rarely seen outside formal documents)). |

| Note: most deep cycle manufacturer's rate capacity at C/20, due to Peukert effect on lead chemistries.((Lithium doesn't not have a significant Peukert effect. Capacity measured by C/20 and by amp-counting will be nearly identical)). In other words, a 100Ah battery will deliver 100A with a 5A load. See table at bottom for other load levels. |
