How Long Will A Deep Cycle Battery Power An Inverter?

A deep cycle battery energizes electronic devices like television, heaters, microwave ovens, washing machines, and toasters, etc. A deep cycle battery is perfect for sustained energy for devices and applications including sporting vehicles, marine applications, and off-matrix sustainable power. It can offer not simply a snappy beginning since it is adaptable to such an extent that it is additionally helpful for materials taking care of and golf trucks.

What is a Deep Cycle Battery?

It looks more like a car battery and is fabricated of lead. It provides sustainable energy ad runs smoothly even when 80% of it is discharged. For these batteries, the number of charges and discharge cycles are correlated. These batteries come with thick active plates having higher density active paste material. Also, it comes with thicker separators (resists corrosion). The alloy used in its construction is antimony.

How Long Will A Deep Cycle Battery Power An Inverter?

  • Its run time will rely upon its ability and extent of the load.
  • Figure out the amps and afterward divide the outcomes by 12. Put it separately.
  • Figure the ampere rating of the relative multitude of electronics to run on the inverter.
  • Thereafter, add 1/2 amps for your inverter. Observe the total and afterward divide that into the main outcome that you have.
  • The figure to achieve will be the run time of your battery in hours. If you have all the more parallel deep cycle batteries, you will have more run time.
  • The measure of time that your inverter powers all electronic devices and hardware associated with it will fluctuate dependent on the power supply and its load upheld.
  • Basically, you will diminish the run time of the battery with the more instruments, gadgets, and machines you plug into it. Also, you can generally interface with numerous batteries for longer runtime.

NOTE: Marine batteries have high reserve ratings, so they can manage repeated drainage and re-charging.

What number of batteries to run an inverter?

  • To measure your battery bank, you need to require the hours should have been increased by watts.
  • The outcome is the complete watts per DC volts equivalent amps required.
  • Thus, if you have a 2000W inverter of 12 volts that you need to maximize, you will pull:

2000W per 12 volts = 166.6 DC amps/hour.

  • In case you will use a 200AMP battery of 12 volts, you should separate the 200A/166.6A, bringing about one and a half-hour of runtime. A model is in case you need to exhaust the battery completely, yet it should not be the situation to forestall shortening its life.


If you want a longer run time, go for either a bigger battery or a parallel interface with more batteries, considering how the batteries are associated. Additionally, if conceivable, operate a similar battery model of a similar brand.
