Quicker starting (a full volt higher than lead and less voltage drop during cranking)
Improved engine management & data logging performance (more stable voltage)
Less horsepower draw from the alternator due to efficient charging (5 times faster than lead),
Lasts 3-5 times longer (especially under the harshest environments),
Much more reliable (less than 1% failure rate)
Significant weight savings. (up to 1/4 the weight)
Don’t self-discharge, so if the battery is disconnected (no draw or via power disconnect switch), they can sit for over a year and still have over 13 volts to start the vehicle.
