A reserve battery, also called stand-by battery, is a primary battery where part is isolated until the battery needs to be used. When long storage is required, reserve batteries are often used, since the active chemicals of the cell are segregated until needed, thus reducing self-discharge. A reserve battery is distinguished from a backup battery, in that a reserve battery is inert until it is activated, while a backup battery is already functional, even if it is not delivering current.
Reserve capacity is a measure of the time, in minutes, that a 12V battery can run before needing to be recharged or replaced. Battery reserve capacity rating and amp hours are important metrics for …
The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.

@Ann Yes, if its a lead acid battery there should be permanent damage if you stored it for two years and never charged it. As you can see, all lead acid battery have a natural discharge rate between 1% to 20% monthly, so at 20% monthly your battery would be 100% discharged in just 5 months and that is using the worst case scenario discharge …
When the "reserve power mode" is triggered on Vista/7/8/10, the battery icon begins to show the red X mark (the critical state icon) and the critical action is triggered on the critical battery level. Additionally, in Vista/7/8 the critical battery notification is triggered on the "reserve battery level" as well.
In conclusion, understanding amp-hour (Ah) ratings of batteries can be confusing for many people. The amp-hour rating is a measurement of the battery''s capacity, not its power output. To determine how long a battery will last or how much power it can deliver, you need to consider the load and the battery''s amp-hour rating.
If a resistor is connected to a battery, the power dissipated as radiant energy by the wires and the resistor is equal to [P = IV = I^2R = dfrac{V^2}{R}.] ...

The relationship between ambient temperature and expected float life is given by the Arrhenius equation. The equation defines the relationship between the ambient temperature and the rate of internal positive-grid corrosion of the battery, which is the normal process of battery aging. A key point to note is that the temperature in question is
There is no way to convert CCA to Ah directly because there is no correlation between them. But for a rule of thumb, you can divide the CCA by 7.25 to get the calculated Ah. For instance, if your battery is marked with a 1450 CCA, it represents 200 Ah. A battery of this rating should last for 25 hours while producing power of 8 amps.
