Energy range
NP1L
Optimised for relatively low current over long discharge periods.
NICAD POWER PTE LTD
NICAMAX
Maintenance-free Ni-Cd · NP1L / NP1M
NICAMAX
NICAMAX combines proven pocket plate nickel-cadmium technology with high gas recombination for dependable stationary backup power. Two ranges cover long-duration energy needs and mixed industrial loads.
The maintenance-free design eliminates routine water addition within the specified operating conditions, while retaining the strength and service life expected of an industrial Ni-Cd battery.
Choose the range for your duty
| Range | Rated capacity | Discharge duty | Typical use |
|---|---|---|---|
| NP1L | 15–1,700 Ah | Low rate · 1–100 hours | Long-duration stationary backup |
| NP1M | 8–1,330 Ah | Mixed loads · 30 minutes–3 hours | Industrial duties with varying current demand |
Select the range against the required current, backup time and final system voltage. Temperature and discharge performance vary by range.
Pocket plate technology
Medium-power range
NP1M
Balances energy and power for duties combining high and low loads.
Reduced water consumption
Gas recombination
A recombination level above 95% and low-pressure venting reduce water loss and gas emissions.
Built for industrial service
- Translucent polypropylene containers allow visual inspection.
- Welded plate tabs and bus bars form a robust current-carrying structure.
- Pocket plates and separators support free electrolyte circulation.
- Terminal covers provide protection for installed connections.
- Service life exceeds 20 years at 25°C.
Applications
- UPS, process control and industrial alarm systems
- Power plants, substations and switching duties
- Onshore and offshore oil and gas facilities
- Medical facilities, airports and building infrastructure
- Starting and emergency backup systems
Charging and maintenance
Single-level charging is specified at 1.42 ± 0.01 V per cell. For two-level charging, use 1.42 ± 0.01 V per cell float and 1.45 ± 0.01 V per cell high charge.
No water addition is required within the recommended −20°C to +40°C operating range at 1.42 V per cell with temperature compensation. Preventive inspection remains necessary. Charger settings and temperature compensation must match the selected installation.
