Why Yuasa UXL GEN2 Exists

Across transmission, distribution and essential infrastructure networks, DC power systems underpin protection, control, communications and operational safety. These systems must perform predictably during fault conditions, outages and abnormal events, often after years of continuous float operation.

Elevated ambient temperatures, non-air-conditioned installations and extended service-life expectations are accelerating degradation in traditional long-life VRLA batteries. In response, asset owners are demanding technologies that deliver measurable lifecycle performance under real operating conditions.

Yuasa UXL GEN2 has been developed as an engineering-led evolution to meet these requirements.

Why Choose the Yuasa UXL Range?

Yuasa UXL GEN2 delivers extended lifecycle performance through targeted advances in VRLA battery design, validated for long-duration float service in critical DC power systems.

  • 20-year design life at 25°C

    Representing a 33% improvement over current UXL platforms*

  • Warranty aligned to operating temperature

    Providing greater confidence
and lifecycle certainty

  • 10-year design life at 35°C

    A new GEN2 design life commitment, for non-air-conditioned environments.

  • 33% improvement in total cost of ownership

    Through reduced replacement cycles and lifecycle efficiency*

*Actual design life may vary (up or down) depending on the operating environment and maintenance regime.

Built for Real
Operating Conditions

Yuasa UXL GEN2 is designed for deployment in environments where temperature, access and maintenance constraints directly influence asset reliability.

This includes elevated ambient temperatures, remote and unmanned installations, and continuous float operation supporting protection and control systems where failure is not an option.

Engineering for these conditions ensures stable performance beyond ideal laboratory assumptions.

Engineered
Lifecycle Outcomes

Yuasa UXL GEN2 is engineered to maintain predictable electrical performance over extended float service, reducing the impact of thermal stress, corrosion and resistance growth.

By extending service life and aligning battery replacement with power system replacement cycles, GEN2 supports fewer interventions, reduced disruption and stronger lifecycle efficiency across critical DC assets.

Product Warranty Commitment

Our Warranty Commitment is critical for Asset Owners and aligned to the Design Life

Product Warranty Structure:

• At 25°C: 8-year guarantee + 12-year pro-rata
• At 35°C: 4-year guarantee + 6-year pro-rata
• T&C’s apply

By directly linking our warranty commitment to environmental conditions, Yuasa’s UXL GEN2 can be trusted for long-term lifecycle planning for critical standby power systems.

Total Cost of
Ownership Advantage

For critical infrastructure operators, lifecycle cost is driven by reliability, replacement frequency and intervention risk — not upfront price alone. Through extended design life, reduced degradation and fewer replacement cycles, GEN2 delivers up to a 33% improvement in total cost of ownership compared to current UXL platforms.*

This enables infrastructure operators to plan with greater certainty, reduce lifecycle costs and improve asset utilisation over decades of service.

*Actual design life may vary (up or down) depending on the operating environment and maintenance regime.
