Routine tubular battery maintenance and upkeep are required to ensure longevity and peak performance. Let’s face it, the battery is the lifeblood of any inverter, and a faulty battery means an unreliable power supply and, in some cases, total failure. 

Here are 5 helpful tips to maintain your Kartel tubular battery:

1. Always check the water level of the battery.

Every two months, check the water level of your Kartel tubular battery to ensure it hasn’t fallen below the expected level. Because there is less water in the battery, there is less electrolyte, which can reduce its power storage and delivery capacity. To ensure adequate power supply during outages, top up the water level every couple of months during tubular battery maintenance.

Also, avoid using tap water for refills because it contains a lot of impurities. Choose distilled water.

2. Decontaminate the Terminals

Battery terminals are prone to rust and corrosion, which can harm the inverter’s current flow capacity. If the tubular battery’s terminals are rusting, apply a solution of baking soda and hot water to the corroded area, or scrape it off with a toothbrush.

After cleaning the terminals, apply Vaseline or petroleum jelly to prevent further corrosion.

3. Check your kartel tubular battery when it is fully charged.

Make sure it’s fully charged before performing a maintenance check. So, before you begin the tubular battery maintenance, make sure the battery has been plugged in for at least 10-15 hours. Also, only begin the battery maintenance after the front panel of your inverter has been removed and the inverter has been disconnected from the wall socket.

4. Ensure that your kartel tubular battery is not overcharged.

During a power outage, the inverter uses the power stored in the battery to power the appliances. Furthermore, if the battery is overcharged during a power outage, the backup time will be reduced.

As a result, it’s best to turn on only essential devices during a power outage. It will improve the battery backup as well as its longevity.

5. Other Maintenance Suggestions

Check that the vents around your battery are open and free of dust. Blocked vents can lead to hydrogen gas accumulation, which can cause your battery to burst.

Install the battery in a location that is out of reach of your children for maximum safety. Ensure that the battery is properly ventilated.

Finally, if your battery is damaged or completely dead, it’s time to replace it. You’ll know when your battery needs to be replaced if you perform regular checks.


With these inverter battery maintenance tips, you can ensure that your tubular battery performs optimally in terms of efficiency, performance, and durability.
