A good reserve capacity in a battery is the amount of time a fully charged battery can sustain a specific load without discharging below a certain voltage. Typically, the reserve capacity of a battery is measured in minutes and is an important factor to consider when choosing a battery for your application.

How do you calculate battery reserve capacity?
To calculate the reserve capacity of a battery, you need to perform a discharge test. The discharge test involves applying a constant load to the battery until it reaches a predetermined voltage. The time it takes for the battery to reach that voltage is the reserve capacity. For example, if a battery is discharged to 10.5 volts over a period of 140 minutes, the reserve capacity of the battery is 140 minutes.
What does a 140 reserve capacity mean in a battery?
A reserve capacity of 140 means that the battery can sustain a specific load for 140 minutes before discharging below a certain voltage. This value is an indication of the battery’s ability to provide power in case of a power outage or when the primary power source is unavailable.
What does 180 RC mean on a battery?
A reserve capacity of 180 RC means that the battery can sustain a specific load for 180 minutes before discharging below a certain voltage. This value is important to consider when choosing a battery for applications that require backup power, such as emergency lighting, security systems, and medical equipment.
In conclusion, understanding the reserve capacity of a battery is crucial when choosing the right battery for your application. A battery reserve capacity chart can help you compare different batteries and choose the one that meets your power needs. When selecting a battery, it is important to consider your power requirements, application, and budget.
