# Battery Reserve Capacity ↔ Amp Hours Calculator

Amp-Hours (AH):

## Introduction

A battery’s Reserve Capacity (RC) and Amp-Hours (AH) are important metrics when it comes to estimating the performance and capacity of a battery. Reserve Capacity is typically expressed in minutes and refers to the amount of time a fully charged battery can deliver a specific electrical load before dropping below a usable voltage level. Amp-Hours, on the other hand, represent the total energy storage capacity of a battery and are measured in ampere-hours.

This Battery Reserve Capacity to Amp-Hours Calculator is a useful tool that allows you to convert Reserve Capacity in minutes to Amp-Hours using a simple formula. In this article, we will walk you through how to use this calculator effectively and provide a step-by-step guide, including the formula and an example calculation.

## How to Use

To use the Battery Reserve Capacity to Amp-Hours Calculator, follow these steps:

1. Enter the Reserve Capacity of the battery in minutes into the designated input field.
2. Click the “Calculate” button to initiate the calculation.

The calculator will then convert the Reserve Capacity to Amp-Hours and display the result.

## Formula

The formula used to calculate Amp-Hours (AH) from Reserve Capacity (BR) is as follows:

AH = (BR * 60 * 25) / 3600

Where:

• AH: Amp-Hours
• BR: Reserve Capacity in minutes

## Example

Let’s say you have a battery with a Reserve Capacity of 100 minutes, and you want to find its Amp-Hours rating. Using the formula provided:

AH = (100 * 60 * 25) / 3600 = 416.67 Amp-Hours

So, the battery has an Amp-Hours rating of approximately 416.67 AH.

## FAQs

### Q1: What is Reserve Capacity?

Reserve Capacity (RC) is a measure of the time a battery can deliver a specific electrical load before its voltage drops below a usable level.

### Q2: Why is Amp-Hours important for batteries?

Amp-Hours (AH) represent the total energy storage capacity of a battery, indicating how much current the battery can supply over time. It is a crucial metric for understanding a battery’s capacity and performance.

### Q3: Can I use this calculator for different battery types?

Yes, this calculator can be used for various battery types, as long as you know the Reserve Capacity in minutes.

## Conclusion

The Battery Reserve Capacity to Amp-Hours Calculator is a valuable tool for anyone working with batteries, whether for automotive, marine, or other applications. By simply entering the Reserve Capacity in minutes, you can quickly calculate the Amp-Hours, allowing you to make informed decisions regarding battery selection and usage.

Understanding the relationship between Reserve Capacity and Amp-Hours is essential for choosing the right battery to meet your power needs. With this calculator and the provided formula, you have a convenient way to make these calculations accurately and efficiently.
