Optimizing Battery Performance: Tubular Battery 12V Battery Equalization

The Science Behind Tubular Battery 12V Battery Equalization, Su-vastika has developed a new approach to equalizing cells in tubular lead acid batteries of single battery 12V. The biggest challenge faced by Inverter/UPS is that once the Tubular battery is installed then after a year or so the 6 cells in a 12V battery do not get equally charged and discharged. As the sulfation start building on the plates as the tubular battery is kept on state of charge for long and the regular charger of inverter has no such property to vary the boost voltage and float voltage based on temperature and break the sulfation after every 10 to 20 cycle once.

During the process, one of the cells in the tubular battery gets overcharged and the rest of the cell remains undercharged. So let us take an example of charging of Tubular battery of 200 Ah when we charge this battery with 20 Amps charging current the battery keeps charging with the charging current and stops the battery charging at 14.4 volts. At this stage, all 6 cells have to be charged at 2.4 Volts to make them equal which is not the case as when the battery is used for more than one year the cell balancing starts getting imbalanced. So when we charge the battery with the higher charging current which happens in Solar charging as the solar charge controllers used in the market with higher rating of solar panels tend to put more charging current in the Tubular battery. This becomes the major reason for the water in the battery getting evaporated and cells getting hard and the equalization is affected the most. So at Su-vastika we have inbuilt this new charging technique using AI in our product range of Pure Sinewave UPS having ATC models to start with.

Here’s a breakdown of the key points:
