The cell construction with the largest electrolyte reserve and proven EPzS technology using the tubular design of plates with low antimony alloys in conjunction with the adjustable charging mode, results in significantly extended intervals for topping up distilled water. PzRM cells are manufactured and tested in accordance with EN60254-1 and IEC254-1.

The main advantages of TAB Aqualess (PzRM) batteries:

The water replenishment period is significantly reduced,
Lower water consumption,
Low maintenance and operating costs,
50% to 80% reduced requirements for gas release and ventilation,
20% to 30% shorter charging time,
Cost savings due to lower energy consumption from 10% to 20%,
Charge factor reduced from standard to 1.07,
Working temperature reduced by an average of 5 ° C,

Battery TAB Aqualess specification:

Water make-up period extended to 12 weeks (100 cycles, normal operation 80% of the nominal capacity C5, one cycle per day, 5 days a week, electrolyte T = 30 ° C),
In the case of these batteries, appropriate rectifiers (Hf, IUIa, impulse rectifiers) with a charging coefficient of 1.07 should be used,
The cells are equipped with an electrolyte mixing system (using a rectifier with an integrated air pump) to prevent electrolyte stratification and ensure optimal charging,
The batteries are installed with the central water refilling system (BFS),
Each battery has an electrolyte level sensor. The red light signals the user to refill water
