This term refers to the duration a battery can sustain a load when the primary power source fails, typically measured in minutes based on the battery's discharge rate.
What is a reserve battery?
This allows the electrolyte to remain inert and makes reserve batteries well-suited for military and aerospace applications. Product specifications for reserve batteries include voltage, capacity in ampere-hours (AH), reserve capacity (RC), energy density, operating temperature, and terminal connections.
What are the product specifications for reserve batteries?
Product specifications for reserve batteries include voltage, capacity in ampere-hours (AH), reserve capacity (RC), energy density, operating temperature, and terminal connections. Choices for terminal connections include button top, screw type, springs, solder, bolt-on, plug-in socket, snap fastener, wire or cable, and other.
In the reserve structure, one of the key components of the cell is separated from the remainder of the cell until activation. In this inert condition, chemical reaction between the cell components (self-discharge) is prevented, and the battery is capable of long-term storage.
Is battery reserve capacity the same as amp hours?
No, reserve capacity is not the same as amp hours; these are separate measurements that reflect different things. Battery reserve capacity is a simple measure of time, while amp-hours measures the number of amps a battery can provide over an hour-long period. While these two measurements are not the same, they are related.
Are reserve batteries still used?
In recent years, however, the use of reserve batteries has declined because of the improved storability of active primary batteries and the limited number of applications requiring extended storage. Most of these applications are for special military weapon systems.
What are the performance characteristics of a reserve battery?
The performance characteristics of the reserve battery, once activated, are similar to those of the active lithium batteries, but with a penalty of 50% or more in specific energy and energy density due to the need for the activation device and the electrolyte reservoir.
