Differences Between PB/SB, PB/CA, and CA/CA Grid Batteries

At FQS Battery, we offer a wide variety of batteries designed for different applications, with diverse technologies and performance levels.

According to their technology, we can distinguish the following main types:

Within Lead-Acid batteries, a key factor influencing their performance is the composition of the grids. This characteristic can make a significant difference, especially depending on the intended use of the battery.

Below, we explain the different types of grids we use in our batteries and how their characteristics impact product performance and lifespan.

1 – Grid Composition

Pb/Sb (Lead-Antimony):
The grids are made with a lead and antimony alloy. This alloy improves mechanical strength and deep cycle tolerance.
Pb/Ca (Lead-Calcium):
The grids combine lead and calcium in the positive grid and lead-antimony in the negative. This design seeks a balance between mechanical strength and reduced water consumption.
Ca/Ca (Calcium-Calcium):
Both grids (positive and negative) are made with a lead and calcium alloy. This significantly reduces water consumption and self-discharge.

2 – Water Loss and Maintenance

Pb/Sb:

– Generate more gases during charging due to the use of antimony.

– Require periodic maintenance (distilled water refilling).

Pb/Ca:

– Generate fewer gases than Pb/Sb, but still more than Ca/Ca.

– Have reduced maintenance, but are not entirely maintenance-free.

Ca/Ca:

– Emit very few gases and are practically maintenance-free.

HEAVY-DUTY BATTERIES

3 – Self-Discharge

Pb/Sb:

High self-discharge rate due to antimony in the grid.

Pb/Ca:

Lower self-discharge than Pb/Sb, but higher than Ca/Ca.

Ca/Ca:

The self-discharge rate is significantly lower, making them ideal for prolonged storage.

4 – Durability and Resistance

Pb/Sb:

They are more resistant to deep charge and discharge cycles, making them ideal for heavy-duty applications.

Pb/Ca:

Offer intermediate durability: greater resistance than Ca/Ca, but less than Pb/Sb in deep cycles.

Ca/Ca:

Less resistant to deep cycles, designed for use in more stable conditions, such as vehicle starting.

5 – Cost

Pb/Sb:

More economical, ideal for industrial applications or where initial cost is an important factor.

Pb/Ca:

Moderately economical, offering improvements in maintenance and performance.

Ca/Ca:

They are less economical due to their advanced technology and maintenance-free design.

6 – Applications

Pb/Sb:

Used in heavy vehicles, industrial machinery, solar systems, and applications with frequent deep cycles.

Pb/Ca:

A hybrid option, suitable for vehicles and equipment with moderate use and less need for maintenance.

Ca/Ca:

Primarily designed for modern automobiles and applications where low self-discharge and minimal maintenance are essential.

Conclusion

Battery choice depends on the application:

Pb/Sb: If you need durability and resistance to deep cycles (solar systems, heavy machinery).
Pb/Ca: Ideal for versatile applications with less need for maintenance.
Ca/Ca: Perfect for modern vehicles and users seeking convenience and low maintenance.
