The ESSEM TUBULAR BATTERIES are designed extremely strong and ECO FRIENDLY The ESSEM Tubular Battery is manufactured fully taking into account the mandatory characteristics of the battery needed for UPS and Invertors. This battery is produced processing the basic raw materials such as lead and lead oxide. The battery is thoroughly tested by taking required initial charge and discharge cycles before reaching the market.
This Battery has the following characteristics:-
High Pressure die-cast positive grid delays corrosion to extend life
Low antimony selenium lead alloy to minimize water consumption
High porosity glass and fiber separator avoids cell short circuit
Inter-partition cell welding by resistance welding machine
PVC terminal shrouding cap for electrical safety
Ceramic vent plug to arrest acid fumes and reduce topping up
Water topping up frequency once in 5 months
Life Expectancy more than 5 years
Factory Charged and wet shipped
Shear tester to check cell welding joint
Short circuit tester to check separator short
Air leakage tester to check leakage of top cover sealing
Acid dosing system for battery acid filling
Due to this, the battery can be stored in charged condition, for very long time without getting discharged.
All batteries of same type will have very uniform internal resistance. Large numbers can be connected in series or parallel without any danger of misbalance within the battery bank.
Very low internal resistance gives you high voltage on discharge and extra back up on load.
The tubular batteries are used in the following applications: UPS systems where power demand is for longer period.
