Pure Lead Battery FAQs

No, there isn’t a standard for how a pure lead battery is made. There are differences in grid design (thickness, structure) and paste density that will directly impact performance, lifespan, and high-rate discharge capability. These design factors vary by manufacturer and application focus. Each manufacturer will determine how to best achieve it.

Pure lead batteries use very high-purity lead (typically >99%), with minimal alloying elements to improve mechanical strength and corrosion resistance.

The ideal operating temperature is around 25°C (77°F). Pure lead batteries will suffer a reduced impact on service life due to temperature compared to standard lead acid batteries.

While not strictly mandatory, climate control is highly recommended to ensure optimal performance and maximize service life regardless of the technology chosen.

To determine the best battery size for your system, you must consider the expected load, runtime requirements, temperature, and system voltage. A detailed calculation or system design review is always recommended to ensure every system is a perfect fit for your needs.

For the best combination of power and longevity, high-rate pure lead batteries such as the Pure Lead Plus and Pure Lead Max are typically recommended due to their energy density, compact footprint, and long life in demanding UPS applications.

• Pure Lead Plus – Standard 5-year warranty
• Pure Lead Max – Standard 8-year warranty

While both require backup power for emergencies, how it is delivered will vary greatly.

• Telecom Application: Medium-rate discharge (e.g., C10 rates), focusing on longer, sustained backup.
• UPS Application: High-rate discharge, delivering large amounts of power in a short time. Key differences between the batteries include: -- Grid design (geometry and thickness) -- Paste density -- Discharge profile optimization

Lifespan of VRLA batteries in UPS applications will vary greatly depending on the selected technology.

• Standard VRLA has a life expectancy of 3-5 years
• Pure Lead 5-8 years
• Advanced Pure Lead 8-10 years

This will depend on the depth of discharge, but VRLA batteries typically provide 400–800 cycles.

Achieving a long service life depends on maintaining proper temperature, correct float voltage, regular maintenance, and avoiding deep discharges or overcharging. A proactive maintenance strategy is required, including periodic inspections, testing, and timely replacement of weak units to maintain overall system performance and reliability.

Sulfation is typically caused by undercharging, prolonged discharge, or improper storage. In most cases, it is not fully reversible and leads to permanent capacity loss.

Indirectly, yes. Poor connections can lead to increased resistance and improper charging, which may accelerate sulfation.

Both are valid diagnostic methods. Conductance testing is commonly preferred for quick and reliable field assessments.

Yes, it remains one of the most reliable methods to validate actual battery capacity and system performance. Typically, once a year or according to industry standards and site criticality. Excessive testing should be avoided to prevent unnecessary battery stress.

Industry standards such as IEEE and manufacturer guidelines should be followed for proper maintenance and safety.

If needed, an equalization charge may be performed if the UPS allows it, but only under controlled conditions and according to the manufacturer’s recommendations. How long to run it for will depend on system conditions and should follow our guidelines to avoid overcharging.

Proper commissioning includes verifying installation, measuring baseline values (voltage, temperature, impedance), and documenting these parameters. Recording this data is highly recommended for warranty validation and future comparisons.
