In today’s time, most of us depend on inverters for a seamless power supply to avoid any hindrance in our routine. This is because the growing work pressure leaves no room for us to sit around and wait for the grid power to get restored.

If you are using an inverter system, we are sure that you must be already aware of the numerous benefits that it brings to the table. Now, you must have enough knowledge to get the finest one for your home. Unfortunately, however, when it comes to inverter batteries, most of us tend to rely on the words of the salesperson rather than figuring things out for ourselves.
Do you notice that your inverter battery backup is not lasting for as long as it should? Well, don’t worry. In this article, you will learn how to calculate 150Ah battery backup time, along with some tips to maximize the backup time of your inverter battery.
How to Calculate 150Ah Battery Backup Time?
Calculating inverter/UPS battery backup time is not rocket science. All you need to be aware of are a few parameters upon which the 150Ah battery backup time is dependent. These parameters are power consumption, the power of the load, and the battery capacity.
Generally, an inverter battery is expected to last around 5 to 10 hours when fully charged. However, you can also calculate the accurate 15Ah battery backup time with the formula below.
Backup Time (hours) = Battery Capacity (Ah) * Input voltage (V) / Total Load (Watts)
Let’s take a hypothetical situation wherein you have an inverter battery with a capacity of 150Ah and an input voltage of 12V. Say you want to run two fans, two tube lights, and 1 Wi-Fi router on the inverter battery. Let’s apply the formula to find out how long your appliances can run in this scenario:
- 2 fans = 75*2 = 150 Watts
- 3 lights = 40*3 = 120 Watts
- 1 Wi-Fi router = 1*20 = 20 Watts
Therefore, the sum total of the load in your case is 150 + 120 + 20 = 290 Watts
Now, in the final stage, let’s apply all these values in the formula.
Backup Time (hours) = 150 X 12/290 = 6.2 (approx.)
Hence, in this case, the 150Ah battery backup time is approximately 6.2 hours, i.e., it can power your devices for 6.2 hours when fully charged.

How Does Battery Capacity Affect Inverter Backup Time?
Let’s keep all the values the same as above except the battery capacity and then figure out how the inverter battery backup time can be affected by the battery capacity.
i. In case the battery capacity is 110Ah
Backup time = 110 X 12/290 = 4.5 hours (approx.)
Hence, you will get a battery backup of 4.5 hours if the capacity of your inverter battery is 110Ah.
ii. In case the battery capacity is 220Ah
Battery Backup time = 220 X 12/290 = 9.1 hours (approx.)
In this scenario, your inverter battery can power your appliances for 9.1 hours.
These two examples make it clear that your battery’s capacity significantly determines your battery backup time. That is to say, the greater the battery capacity, the higher the battery backup time will be.
How to Improve Your 150Ah Battery Backup Time?
Here are four ways you can improve your power backup UPS system:
1. Avoid Rusting and Corrosion
Since corrosion depreciates the performance of your inverter battery by reducing its current flow, it is essential to always keep it rust/corrosion free.
2. Do Not Overload
During a power cut, if your inverter battery is overloaded, it would lower the backup time. Therefore, it is preferable to disconnect all those devices that are not needed on an urgent basis but are consuming a lot of energy.
3. Use Energy-Saving Gadgets
Using energy-saving devices can be a great idea to reduce power consumption. For example, use LED bulbs instead of traditional tube lights or bulbs, as it minimizes almost 75% of power consumption.
4. Check Water Level
Check the water level of your inverter battery at least once every two months. Note that the water level should remain between the minimum and maximum limits. Moreover, do not use tap water as it contains contaminants that might affect the performance of your battery.
