I'm assuming you're purchasing a new truck with a choice of batteries? Variables, such as working enviroment, physical size of truck, shift work, etc need to be explored in order to give an accurate answer.

Lifts are designed around an 8 hr shift. Installing a larger A/H battery than needed may mean that the lift needs a charge right in the middle of a shift. If this becomes the norm- overcharging the battery may become prevolent- shortening the life of the battery.

I think that the time spent investigating the advantages of different A/H batteries would be better spent developing a effective charging system that works around the 8-8-8 system.
In smaller operations with limited lifts, the 8-8-8 system is very difficult to follow. Unless a system is in place & followed, overcharging the battery becomes the norm & battery life deminishes greatly.
