The following battery characteristics must be taken into consideration when selecting a battery: 1) Type See primary and secondary batteries page. 2) Voltage The theoretical standard cell voltage can be determined from the electrochemical series using Eo values: Eo (cathodic) – Eo (anodic) = Eo (cell) This is the standard theoretical voltage.
A battery's characteristics may vary over load cycle, over charge cycle, and over lifetime due to many factors including internal chemistry, current drain, and temperature. At low temperatures, a battery cannot deliver as much power.
The battery cycle life for a rechargeable battery is defined as the number of charge/recharge cycles a secondary battery can perform before its capacity falls to 80% of what it originally was. This is typically between 500 and 1200 cycles. The battery shelf life is the time a battery can be stored inactive before its capacity falls to 80%.
Thus the nominal voltage is determined by the cell chemistry at any given point of time. The actual voltage produce will always be lower than the theoretical voltage due to polarisation and the resistance losses (IR drop) of the battery and is dependent upon the load current and the internal impedance of the cell.
The theoretical capacity of a battery is the quantity of electricity involved in the electro-chemical reaction. It is denoted Q and is given by: Q = xnF (6.12.1) (6.12.1) Q = x n F where x = number of moles of reaction, n = number of electrons transferred per mole of reaction and F = Faraday's constant
