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:
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:
lower cost to recycle
less manufacturing energy required
less CO2 used in manufacturing
Despite their inherent market dominance, traditional lead-acid batteries have a number of drawbacks that automotive manufacturers have sought to overcome:
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.
Ultimate Battery Co has developed patented Duophasic advanced automotive battery technology that solves the issues associated with traditional SLI and stop-start batteries.
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
Due to their unique modular design, UBC Duophasic COR batteries can be easily scaled in any of three ways:

43% lighter weight:
12-15kg (26-33lbs) on-board weight reduction
2x greater energy density:
Typically 15kg (33lbs) per vehicle per year
Wider operating temperature range:
-40 to +88oC (-40 to +190oF)
UBC Duophasic COR batteries are fully sealed, chip free, and require no maintenance.
UBC batteries already exceed the EUROBAT 2030 objectives, providing the automotive industry with significant environmental and performance benefits.
