To calculate battery charging time put values in given box by using our battery charge time calculator.

Table of Contents:

## Formula

MTFC (10% Efficiency Loss) = ((BC / CRC) * 11)10

MTFC (20% Efficiency Loss) = ((BC / CRC) * 12)10

MTFC (30% Efficiency Loss) = ((BC / CRC) * 13)10

MTFC (40% Efficiency Loss) = ((BC / CRC) * 14)10

MTFC (No Efficiency Loss) = ((BC / CRC) * 10)10**Where,**

MTFC - Maximum Time To Full Charge

BC - Battery Capacity

CRC - Charge Rate Current

## Battery Charge time Calculator

A rectifier unit used to change alternating to direct power for charging a storage battery is called as a battery charger. It is also known as charger. A battery generally consists of an anode, a cathode, and an electrolyte. The charge current depends upon the technology and capacity of the battery being charged. For example, the current that should be applied to recharge a 12 V car battery will be very different from the current for a mobile phone battery.

A primary battery is one that can convert its chemicals into electricity only once and then must be discarded. A secondary battery has electrodes that can be reconstituted by passing electricity back through it; also called a storage or rechargeable battery, it can be reused many times.

A battery is an electrochemical cell (or enclosed and protected material) that can be charged electrically to provide a static potential for power or released electrical charge when needed. This advanced online Battery Charge Time Calculation tool is used to calculate the maximum charge time of batteries, based on the entered information.

**Example:**

Calculate the maximum time taken by a battery to charge by the given details.

Battery Capacity (mAh) = 25

Charge Rate Current (mA) = 30

**Solution:****Apply formula:**

MTFC (10% Efficiency Loss) = ((BC / CRC) * 11)10 = (25/30)*1110**MTFC (10% Efficiency Loss) = 0.916666 (Hours)**

MTFC (20% Efficiency Loss) = ((BC / CRC) * 12)10 = (25/30)*1110**MTFC (20% Efficiency Loss) =1(Hours)**

MTFC (30% Efficiency Loss) = ((BC / CRC) * 13)10 = (25/30)*1310 = 1.08333**MTFC (30% Efficiency Loss) = 1.083333(Hours)**

MTFC (40% Efficiency Loss) = ((BC / CRC) * 14)10 = (25/30)*1410 = 1.1666**MTFC (40% Efficiency Loss) = 1.1666 (Hours)**

MTFC (No Efficiency Loss) = ((BC / CRC) * 10)10 = (25/30)*1010 = 0.83333**MTFC (No Efficiency Loss) = 0.83333 (Hours)**
