how long will a 100ah battery last

100Ah batteries are very large and common in all parts of life, they can be used for caravans, solar batteries, home energy storage, travel backup, car batteries, etc.

How long will a 100ah battery last？

The performance and range of the battery is also related to its own voltage, in layman's terms, the higher the voltage the stronger the ability to sustain performance release, if your battery is 12V 100Ah, then a fully charged and functioning battery can output 12V x 100Ah = 1200Wh

Battery Capacity (Wh) = Ampere Hours (Ah) × Voltage (V)

If you use a computer device that is more commonly used at home, for example, if the total power consumption of the computer is 300w, then 1200wh/300w = 4h 

Then the 12v 100ah battery can be used to run your 300w computer for 4 hours

Similarly, if your battery is 24V 100ah, then a fully charged and functioning battery can output 24V × 100AH = 2400Wh

Then the 300w computer can be used for 8h

The following is my list of some wattage and battery power time of most household appliances

 (the power consumption of appliances is referenced to the power consumption of Chinese household appliances, and the battery is a large lithium battery of 51.2v 200ah)

The value can be different from each place of the appliance, you can calculate the approximate power consumption, so you can buy the corresponding products

In short If your family wants a better backup battery to power your home, that a large battery will be a very good choice, if you are traveling to use some small appliances, etc., then the 24v large battery and 12v large battery can basically meet any of your daily needs
