## Battery Charge Time Calculator

Battery Charge Time Calculator is used to estimate the time required to charge a battery. The tool takes the values of the capacity of the battery and the charging rate to calculate the estimated time to charge a battery.

## What is the battery charge time?

Battery charge time is the time that is required to charge a battery to its maximum capacity. The charge time of the battery is totally dependent on the charge rate current and battery capacity.

**Battery capacity**

Battery capacity is the amount of energy that a battery can store, usually measured in ampere-hours (mAh).

**Charging rate**

The charging rate is the rate at which the battery can be charged, typically measured in amperes (mA).

## Formula of battery charge time

The formula for battery charge time is:

**Time = battery capacity/charge rate current**

## How to calculate battery charge time?

Here is an example to calculate battery charge time.

**Example**

Calculate the battery charge time if the capacity of the battery is 7000 mAh and the charging rate is 40 mA.

**Solution **

**Step 1:** Take the given data.

battery capacity = 7000 mAh

charge rate current = 40 mA

**Step 2: **Take the formula of battery charge time.

Time = battery capacity/charge rate current

**Step 3: **Put the values in the battery charge time formula.

Time = 7000/40 = 175 hours.
