Supreme Dry Battery MF (Aki Kering) NS-40Z 1pc

1. Hydrometer.
· At full charge, the electrolyte specific gravity is 1.28 while at 50% of charge considered the minimum serviceable condition, the specific gravity is typically 1.22, in a typical situation. When the specific gravity drops to 1.10. The battery is full discharged.

2. Double lid with labyrinth structure.
· Prevent electrolyte losses by collection and returning liquid to the reservoir.
· Vents allow the battery to "breathe" during temperature changes and charging.

3. Flame Arrester.
· Safety system.
· Prevent the explosion from spark of outside.
· Minimize the acid-leakage.
· Prevent the inflow of dust.

4. Wrought lead-Calcium Grids.
· Offer considerable strength.
· Resistant to grid corrosion.
· Over-charge resistant.
· Minimal gassing and water usage.
· Less self-discharge.
· Resist thermal runaway.
- Diamond Mesh-increase the conductivity.
- Central lug-increase the electricity collection characteristic.
- High density active material with special additives-high starting performance.

5. Double lid.
· Prevent contamination and also add to the strength and rigidity.
· Include permanent flame arrester to prevent accidental explosion from external sparks or flame.
· Have hydrometer built in for faster checking.

6. Centered Cast-on Plate Straps.
· Stronger than the thinner gas-burned conventional connectors.
· Reduce the lever action movement resulting from road shock.

7. Polypropylene Case.
· Reinforced design is precisely tailored to support the battery elements.
· Material is exceptionally strong, durable and withstands the shock and vibration from the road.

8. Low-Resistance Envelope Separators.
· Encapsulate negative plates.
· Improve vibration durability.
· Prevent "treeing" and internal shorting between positive and negative plates.

Hot-melting.
- Improve the anti-vibration characteristic.

Ergonomic easy carry down fold handle.
- Cold forging terminal - High strength from fine structure and prevent the leakage.

NST Special Tissue for Positive Plates.
- Prevent the active material.
- Shedding from frequent.
- Charging and discharging.

REG Rolled Expanded High Tin Grid.
- Creating sub grain boundary.
- Which provide longer life span against corrosion.
- Ergonomic easy carry down fold handle.
