All tubular batteries behave similarly to start with, but obviously, not all tubular batteries are the same. The difference lies in the composition of the alloy in the positive support structure, as well as in the way that the main back bone of the plates, called the SPINE, is cast. Cronex Tubular Batteries are low maintenance batteries with positive tubular plates which are known for its excellent characteristic of power back up for longer time duration. Cronex Tubular Batteries are also uniquely designed which contains 25% more electrolyte which acts as a coolant, controls rising temperature of battery and in presence of carbon fitted in water level indicator reverts water back into the battery which comes out due to vaporization enhancing ultra low maintenance to it.
