NPH Range
NPH nickel-cadmium batteries deliver high current over short periods for starting and backup duties. Sintered positive electrodes and plastic-bonded negative electrodes combine high power with compact construction.
The range is suited to demanding duties where available space and voltage limits are important, including railway auxiliaries, engine starting and UPS applications.
Range and performance
| Range | Rated capacity | Discharge focus | Electrode technology |
|---|---|---|---|
| NPH | 11–320 Ah (C5) | Short-duration, high-current duty | Sintered positive / plastic-bonded negative |
Available discharge current depends on the final voltage. Select the cell using the required pulse or backup time and the minimum permissible system voltage.
High-power electrode technology
Negative electrode
Plastic-bonded design
A compact negative electrode works with thin separators to support high-power performance.
Operating duty
Starting and backup
Current capability reaches up to 20 times nominal capacity, depending on the model and duty.
Built for demanding service
- Polypropylene cases are standard; flame-retardant cases are an option.
- Resistance to deep discharge, charge-current stresses and voltage reversal.
- Operating range: −30°C to +60°C.
- Service-life expectation is more than 20 years.
Applications
- Diesel engine starting
- UPS and short-duration standby power
- Railway starting and auxiliary backup duties
Charging and maintenance
At 20°C, single-rate charging is 1.41 ± 0.01 V per cell. For dual-rate operation, use 1.37 ± 0.01 V per cell float and 1.42–1.45 V per cell high charge.
Charging is at constant voltage. Frequent cycling can require different settings, so confirm the charging regime with Nicad Power Pte Ltd. Inspect the installation regularly and follow the selected model’s maintenance instructions.
