What does battery discharging mean

However, in smaller systems that have a relatively few days storage, the daily depth of discharge may need to be calculated. A common way of specifying battery capacity is to provide the battery capacity as a function of the time in which it takes to fully discharge the battery note that in practice the battery often cannot be fully discharged.

The notation to specify battery capacity in this way is written as Cx, where x is the time in hours that it takes to discharge the battery. When the discharging rate is halved and the time it takes to discharge the battery is doubled to 20 hours , the battery capacity rises to Y. The discharge rate when discharging the battery in 10 hours is found by dividing the capacity by the time. This may also be written as 0. Such relatively complicated notations may result when higher or lower charging rates are used for short periods of time.

The charging rate, in Amps, is given in the amount of charge added the battery per unit time i. Note that the battery is only "theoretically" discharged to its maximum level as most practical batteries cannot be fully discharged without either damaging the battery or reducing its lifetime.

Each battery type has a particular set of restraints and conditions related to its charging and discharging regime, and many types of batteries require specific charging regimes or charge controllers. For example, nickel cadmium batteries should be nearly completely discharged before charging, while lead acid batteries should never be fully discharged. Furthermore, the voltage and current during the charge cycle will be different for each type of battery. Poutnik Poutnik 4 4 bronze badges.

When you are using your battery to power electronics in a boat or motorhome application, this becomes an active process. Equally important, you are inactively discharging your battery whenever it is left unused for any period of time, even without a load connected. Privacy Policy. Terms And Conditions.
