Good Fuel Savings


Traditional lead-acid technology provides modest fuel savings in a start-stop system. This system allows the vehicle to automatically turn off the engine while stopped and quickly restart as the driver releases the brake.

Best Fuel Savings


With lithium-ion technology, the micro-hybrid system allows the engine to shut down while the vehicle is coasting at any speed, providing the best fuel economy by maximizing engine-off time.

Better Fuel Savings


A better alternative to lead-acid technology is A123’s lithium-ion energy storage for micro-hybrids. The improved technology enables exceptional fuel economy benefits by utilizing a higher charge acceptance, allowing for regenerative braking. When the vehicle slows, wheels power the alternator and quickly recover energy to store in the battery.
