A viable alternative to lead-acid batteries

Globally, over 1 billion vehicles rely on 12 volt lead-acid batteries to provide start-up and stop-start power for ICE and Hybrid powertrains, and to supply auxiliary power for most EVs.

UBC Duophasic COR modular batteries offer a truly viable alternative – a lighter, more powerful and more sustainable battery, that is affordable when installed in new vehicles or as a drop-in replacement.

Lead-acid SLI batteries remain popular due to a number of factors:

  • 99% of lead is recycled
  • Processes for use are well established
  • Secure supply chains are trusted by vehicle manufacturers
  • Self balancing cell chemistry
  • Safer
  • Environmentally sound

Annual unit sales of 12 volt lead-acid batteries total 286 million, dwarfing lithium ancillary 12V batteries, which have just a 3% market share. Compared to lithium, lead is a far more sustainable choice:

64%

lower cost to recycle

82%

less manufacturing energy required

75%

less CO2 used in manufacturing

The drawbacks

Despite their inherent market dominance, traditional lead-acid batteries have a number of drawbacks that automotive manufacturers have sought to overcome:

  • Lead-acid batteries are heavy, adding unnecessary weight to vehicles
  • Vehicle suppliers need to add more 12 volt battery capacity to meet the demands of increased levels of connected and autonomous services. But adding batteries adds weight, which reduces range or increases emissions
  • Lead-acid batteries are logistically inefficient compared to lighter alternatives
  • Other potential alternatives, including lithium, remain expensive and are considerably less energy efficient to manufacture
  • Original bipolar batteries have also proven to be expensive and are failure prone

The challenge

Vehicle manufacturers require a safe, lighter weight, advanced automotive battery type that not only reduces emissions at comes at a comparable performance and cost to current battery solutions.

Our solution

Ultimate Battery Co has developed patented Duophasic advanced automotive battery technology that solves the issues associated with traditional SLI and stop-start batteries.

Duophasic COR

lighter | powerful | sustainable

UBC Duophasic COR batteries utilise a patented composite lead-carbon construction and perfect edge-to-edge sealing. The result is a lightweight battery that is more sustainable and more affordable.

The unique modular format of UBC Duophasic COR technology enables batteries to be produced in multiple configurations and power outputs to suit any vehicle

Modularity

Due to their unique modular design, UBC Duophasic COR batteries can be easily scaled in any of three ways:

  • Voltage
  • Capacity
  • Size
