A123’s UltraPhosphate Lithium-ion 48V Engine Start Battery sets a new performance standard for micro-hybrid vehicle applications by delivering outstanding cold cranking power with a battery that outperforms incumbent lead-acid technologies. By utilizing advanced chemistry and system design, the A123 solution offers outstanding cycle life, high charge acceptance, and up to a 60% weight reduction over lead-acid. A123’s UltraPhosphate difference provides a robust lead-free solution to the rigorous demands of start-stop and recuperation, which are key fuel saving features of a micro-hybrid vehicle. Already producing a third generation product, A123 continues to set the bar on lithium-ion battery performance.
A123’s robust 48V battery can accept high rates of charge and capture several times more energy from regenerative braking for improved vehicle fuel economy and reduced emissions. This advantage is sustained over product life and does not suffer the severe performance degradation experienced with lead-acid technologies.
A123’s breakthrough Lithium-ion chemistry now delivers a wider temperature operating range for exceptional cold crank performance that outperforms lead acid and also contributes to system reliability.
A123’s UltraPhosphate delivers a solution that widely performs for the life of the vehicle. Long life and high durability in start-stop applications defer the need to replace the 48V Starter Battery, which improves vehicle manufacturers warranty risk and total cost of ownership for the consumer. Cold Temperature Performance Extensive Cycle Life Dynamic Charge Acceptance
