1. Model Type: NPW45-12
2. Nominal Performance: 12V, 45 W/cell at 10-min to 1.60 V/cell
3. Mechanical Specification:
3.1 Dimension: Length : 151 ±1 mm
Width : 65 ±1 mm
Case height : 94 ±1 mm
Overall height : 97.5 ±1 mm
3.2 Terminal: Faston 250 tab
3.3 Mass: 2.7 kg (approx.)
3.4 Container material: ABS (UL94HB)
4. Construction:
The battery is composed of positive and negative plates, separators, electrolyte,
container, lid etc. and is equipped with positive and negative polarity terminals.
Any emitted gas from the battery is minimised with the negative plate gas
recombination method, thus requiring no topping up of electrolyte.
5. External Appearance:
The battery shall be without acid leakage, conspicuous stain, scar or deformation.
6. Performance:
6.1. Temperature of tested battery shall be 20°~25 °C if not specified.
6.2. Discharge performance:

Battery capacity at time of delivery shall be 75% or more, provided it is tested within
14 days after delivery.
After delivery, the capacity shall exceed 95% of nominal within 3 charge/discharge
cycles or 10 days on float charge.
