Basic features
- Special design and optimized alloys minimizes water consumption
- Minimal maintenance costs due to the longer watering interval
- Extended watering intervals (up to 13 weeks)
- Best solution to optimize customer’s service cost
- Available in 125Ah & 155Ah Plates
Minimum maintenance costs
- Water refilling represents a significant part of the overall time consumed in battery maintenance.
- The watering interval depends mainly on two factors:
Acid reserve volume of the battery
- Special design
Water loss per cycle
- Water loss per cycle is the result of the water decomposition (electrolysis) and this is directly proportional to the overcharge factor.
Applications
Warehouses & Logistic centers with large forklift
… where maintenance and energy cost are really high (high % of the overall forklift operation and maintenance budget)
Rental or Leasing contracts of large forklift fleets
…where maintenance is part of the service agreement/contract
Design & specification
- Same plate height with PzS, tubular positive plate design, same capacity
- Reduced prism height creates larger electrolyte reserve thus increases the watering interval
- Low antimony (Sb) grids, less antimony “poisoning”, reduced water decomposition
- Use of good quality gauntlet and special NAM formula minimizes mass shedding
- Available currently for 125 and 155 Ah plate heights

Charging curve
- The pulse cycle is specially designed to achieve optimum acid mixing and charging effects without excessive stress on the battery.
- The number of pulse cycles varies automatically according to the battery needs. Number of pulses is less when previous depth of discharge is low. No unnecessary charging – No water loss for nothing.
- The acid mixing precedes the overcharging phase which now becomes more effective and shorter.
- The du/dt criteria for the end of charge, guaranties the complete recharge of the battery with the minimum overcharging every time with minimal water loss.
