Find out how long your car battery or any direct current battery can last with our Battery Life Calculator! This simple but powerful application allows you to accurately estimate the operating time of your battery, taking into account the battery capacity in amp-hours (Ah), voltage (V), connected load in watts (W), and the efficiency of a DC/AC inverter.

Main features:
Accurate calculation: Enter the battery capacity in amp-hours (Ah), the battery voltage and the connected load (W), and get an accurate calculation of the duration in hours and minutes.
Configurable Inverter Efficiency: Adjust the efficiency of the DC/AC inverter you are using (in percentage), from lower values ​​to high efficiency inverters.
Quick Time Estimate: Get the estimated battery run time, divided into hours and minutes, for a quick, easy-to-understand readout.
Compatibility with different devices: From household appliances to mobile devices, know how many more hours you can continue using your devices.
List of common appliances: Consult a table with the average consumption of appliances such as televisions, refrigerators, fans, and more, to help you make more accurate estimates.
Ideal for:
Car and electric vehicle battery users.
People who use batteries with inverters to power electrical devices in their homes, caravans or campsites.
Electricians and technicians who need to make quick battery durability calculations.
Do-it-yourselfers using inverters with batteries for small projects.
Anyone who wants to estimate the life time of a battery with a connected load.
How it works:
Enter the capacity of your battery in Ah, the voltage (V), the connected load (W), and adjust the efficiency of your inverter (default at 90%).
The app will automatically calculate the estimated duration in hours and minutes.
Consult our list of appliances to obtain the approximate consumption of the devices you want to connect to the battery.
