Normal operation of the battery
For example, if the battery is fully charged again after 80% discharge, the battery can only discharge 80% of its charge. This is the so-called memory effect. Of course, a few complete discharge/charge cycles will bring the NiCd battery back to normal operation.

How a battery works
A battery is a device that stores chemical energy, and converts it to electricity. This is known as electrochemistry and the system that underpins a battery is called an electrochemical cell. A battery can be made up of one or several (like in Volta''s original pile) electrochemical cells. Each electrochemical cell consists of two electrodes ...

Difference Between Online UPS and Offline UPS
During normal operation, the power from AC mains is directly supplied to the output through a static transfer switch.At the same time, the AC is converted into DC using a rectifier to charge the battery using a charge controller. But unlike Online UPS, the inverter does not draw current from the battery until the primary supply (AC main) is interrupted.

UPS basics
In normal operation, these feed incoming utility AC power to IT equipment. If the AC input supply falls out of predefined limits, the UPS utilizes its inverter to draw current from the battery, and also disconnects the AC input supply to prevent backfeed from the inverter to the utility. The UPS stays on battery power until the

9.3: Charge Flow in Batteries and Fuel Cells
Figure (PageIndex{2}) illustrates the charge flow in the battery during normal operation. A complete circuit is formed not just by the flow of electrons but by a combination of the flow of electrons and ions [128]. Electrons flow away from the negative terminal (anode) through the load. Negative OH(^-) ions flow away from the positive ...
Electric battery
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons. When a battery is connected to an external electric load ...

Is this normal operation for a Power Awning?
Seems like my Dometic Power awning only moves when the rig is connected to shore power or on 12 volt if the battery is fully charged. It will not move on D/C when the battery voltage is below 12.7-12.6 volts. I''m worried that the current draw is excessive indicating a soon to fail motor. I had the battery load tested and it''s within range.
