(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
The battery C Rating is the measurement of current in which a battery is charged and discharged at. The capacity of a battery is generally rated and labelled at the 1C Rate (1C current), this means a fully charged battery with a capacity of 10Ah should be able to provide 10 Amps for one hour.
Charge and discharge rates of a battery are governed by C-rates. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes.
At higher C Rates some of the energy can be lost and turned in to heat which can result in lowering the capacity by 5% or more. To obtain a reasonably good capacity reading, manufacturers commonly rate alkaline and lead acid batteries at a very low 0.05C, or a 20-hour discharge.
Abbreviated from “Current rate,” the C-rate is a measure of the rate at which a battery is charged or discharged relative to its capacity. It is also called “charge and discharge rates” and the unit is C that represents for capacity.
The charging rate depends very much on the battery’s chemistry – Lead-acid, Ni-Cad, NiMh, Lithium-ion, etc. The maximum charge rate for wet cell lead acid battery is about 10% To 15% of the amp hour rating and 30% for Lithium-ion batteries. Suppose you have 12v 120 Ah battery (assuming it’s lead-acid) should be charged at 12 to 24 Amps max.
