In aircraft the continuous drain capacity is also a concern - you want navigation and communications if the alternator dies before you get to the ground. The lithiums are more than twice the cost, but weight is less than a fourth (VERY significant) and they seem to be expected to last 6 years in use instead of the lead acid's 5 years expected lifespan. They also have to provide spacers for the battery box in certificated aircraft. I will be using them in the experimentals I'm working on.
