Life Span Of Tubular Battery
The average lifespan of an inverter battery depends on the type of battery and how it's used and maintained:
- Lead-acid batteries
These are the most common type of inverter battery and typically last 3–5 years. They require regular maintenance, such as checking the electrolyte levels.
- Lithium-ion batteries
These batteries are more expensive but can last longer, typically 8–10 years. They are relatively maintenance-free.
- Tubular batteries
These batteries can last up to 7–10 years with proper maintenance. However, they may start to fail within the first two years of use.
Other factors that can affect the lifespan of an inverter battery include:
- Deep discharges: The more frequently a battery is deeply discharged, the shorter its lifespan.
- Overcharging: Improper charging cycles can shorten the battery's life.
- Exposure to heat: Extreme temperatures can shorten the battery's life.

How to Calculate UPS/Inverter Battery Backup Time?
In today's world, where power outages are becoming more frequent and unpredictable, having an Uninterruptible Power Supply (UPS) or Inverter at home or office is essential. But how do you calculate the battery backup time of your UPS or Inverter? This question has been a hot topic lately, with many people searching for answers online. In this blog, we will guide you through the steps to calculate your UPS/Inverter battery backup time, using popular methods and techniques. So, let's get started and learn how to ensure uninterrupted power supply during emergencies!
There are different methods to calculate the battery backup time of your UPS/Inverter. Here are two popular methods:
Method 1: Using Battery Capacity and Load
The first method to calculate UPS/Inverter battery backup time is by using the battery capacity and the load. The battery capacity is the amount of energy that the battery can store, while the load is the amount of energy that your appliances or devices consume.
Step 1:Determine the Battery Capacity in Ah
To determine the battery capacity in Ah, check the battery label or manual. For example, if the battery is labeled as 12V 100Ah, the battery capacity is 100Ah.
Step 2:Determine the Load Wattage in W
To determine the load wattage in W, add up the wattage of all the devices connected to the UPS/Inverter. For example, if you have a computer with a power consumption of 150W and a monitor with a power consumption of 50W, the load wattage is 200W.
Step 3: Calculate the Backup Time
To calculate the backup time, use the following formula:
Backup Time (in hours) =Battery Capacity (in Ah) * Battery Voltage (in V) * Battery Efficiency (in %) / Connected Load (in W/h)
For example,
1. If you have a 1500VA UPS with a 12V 100Ah battery, and the total wattage of your load is 800W, the backup time can be calculated as follows:
Backup time = (battery capacity ÷ power requirement of load) × 0.7
Backup time = (12V × 100Ah ÷ 800W) × 0.7
Backup time = 1.05 hours or 63 minutes
Note: The factor of 0.7 is used to account for battery efficiency and other losses.
2. Suppose you have an inverter battery with a capacity of 150 Ah and an input voltage of 12 V, and you want to power three tube lights, three fans, and a Wi-Fi router using this battery. In this scenario, you may be wondering how long your appliances will run on this battery and what will be the battery backup time. To find out, let's calculate the backup time of your inverter battery and determine how long your devices will be powered.
Taking your inputs into consideration, you can calculate your total load, like:
- 3 tube lights = 40 x 3 = 120 Watts
- 3 fans = 75 x 3 = 225 Watts
- 1 Wi-Fi router = 1×20 Watts = 20 Watts
So, the total load in your case is 120 + 225 + 20 = 365 Watts.
Now, let us apply all these values in the above-said battery backup time formula.
Backup Time (in hours) = 150 x 12 / 365 = 4.9
So, your inverter battery will last around 4.9 hours to keep your needed appliances running.
Method 2: Using Battery Discharge Rate
The second method to calculate UPS/Inverter battery backup time is by using the battery discharge rate. The battery discharge rate is the rate at which the battery discharges during a power outage.
To calculate the backup time using this method, follow these steps:
Step 1:Determine the discharge rate of your battery. This information can usually be found on the battery or in the product manual.
Step 2:Determine the capacity of your battery. This is the same as step 1 in method 1.
Step 3: Calculate the backup time by dividing the capacity of the battery by the discharge rate.
For example, if the discharge rate of your battery is 10A, and the capacity of your battery is 100Ah, the backup time can be calculated as follows:
Backup time = battery capacity ÷ discharge rate
Backup time = 100Ah ÷ 10A
Backup time = 10 hours
Calculating UPS/Inverter battery backup time is essential to ensure uninterrupted power supply during emergencies. The two methods discussed in this blog, using battery capacity and load wattage, and using runtime provided by the manufacturer, can help you determine the backup time of your UPS/Inverter accurately. It's important to keep in mind that backup time can vary depending on several factors, such as battery age, temperature, and load type. Therefore, it's recommended to test your UPS/Inverter regularly to ensure optimal performance during power outages.
How to Improve Your Inverter Battery’s Backup Time?
If you want to improve your inverter battery's backup time, there are several steps you can take to optimize its performance. Here are a few things you can do:
- Choose the Right Battery Capacity: When buying an inverter battery, it's essential to choose the right capacity that meets your needs. The higher the battery capacity, the longer the backup time. Therefore, if you need more backup time, consider buying a battery with a higher capacity.
- Regular Maintenance: Regular maintenance can significantly improve the performance of your inverter battery. Keep the battery clean and dry, and avoid exposing it to extreme temperatures. Also, check the battery water level and top it up with distilled water if needed.
- Limit Connected Load: The more devices you connect to your inverter battery, the shorter the backup time. Therefore, it's crucial to limit the number of devices connected to your battery and use only essential appliances during a power outage.
- Use Energy-Efficient Appliances: Using energy-efficient appliances can help reduce the power consumption of your inverter battery and extend its backup time. Consider replacing your old appliances with new, energy-efficient ones that consume less power.
- Invest in a Solar Panel: If you live in an area with long power cuts, investing in a solar panel can be a good option. A solar panel can charge your battery during the day, which can significantly increase the backup time of your inverter battery.
By following these tips, you can significantly improve the backup time of your inverter battery and ensure uninterrupted power supply during emergencies.
