Victron Energy Lead Carbon Battery

The Victron Energy Lead Carbon Battery offers enhanced performance compared to traditional lead-acid batteries, especially in partial state-of-charge (PSoC) applications. By incorporating a lead carbon composite in the negative plate, this battery reduces sulfation, improves charge acceptance, and extends cycle life.

Key Advantages:

• Improved Partial State-of-Charge (PSoC) Performance: Reduces sulfation and enhances battery longevity.
• Higher Efficiency: Lower charge voltage reduces energy losses and minimizes corrosion on the positive plate.
• Extended Cycle Life:
  • ≥ 500 cycles @ 100% Depth of Discharge (DoD).
  • ≥ 1000 cycles @ 60% DoD.
  • ≥ 1400 cycles @ 40% DoD.

Common Failure Modes of Conventional VRLA Lead-Acid Batteries:

• Softening or Shedding of Active Material: Frequent cycling reduces cohesion of the positive plate due to the transformation between lead oxide (PbO2) and lead sulfate (PbSO4).
• Positive Plate Corrosion: Accelerated corrosion at the end of the charge process due to the presence of sulfuric acid.
• Negative Plate Sulfation: Lead sulfate crystals harden and become impenetrable, leading to decreased capacity.

Lead Carbon Battery Performance:

• Tested to withstand at least 500 full 100% DoD cycles.
• Requires a recommended charge rate of ≤ 0.2C.
• Lower charge voltage increases efficiency and reduces thermal stress.

Recommended Charge Voltage:
