Hydrometer
- At full charge, the electrolyte specific gravity is 1.280 while at 50% of charge considered the minimum serviceable condition, the specific gravity is typically 1.220. In a typical situation when the specific gravity drops to 1.100, the battery is fully discharged.
Heat Sealed Covers
- Prevent contamination and also adds to the strength and rigidity.
- Include permanent flame arresters to prevent and accidental explosion from external sparks of flame.
- Have hydrometer built in for faster checking.
Exclusive Patented Liquid Gas Separator
- Prevents electrolyte losses by collection and returning liquid to the reservoir.
- Vents allow the battery to "breathe" during temperature changes and charging
Centered Cast-on Plate Straps
- Stronger than the thinner gas-burned conventional connectors.
- Reduce the lever action movement resulting from road shock.
Wrought Lead-Calcium Grids
- Offer considerable strength
- Resistant to grid corrosion
- Over-charge resistant
- Minimum gasing and water usage
- Less self-discharge
- Resist thermal runway
Low - Resistance Envelope Separators
- Encapsuate negative plates
- Improve vibration durability
- Prevent "treeing" and internal shorting between pos. and neg. plates
Flame Arrester
- Safety systems
- Prevent the explosion from spark of outside
- Minimize the acid-leakage
- Prevent the inflow of dust.
