The Ducati ST4S takes the YT12B-BS case. The Antigravity AT12BS RE-START is a drop-in for that case: 360 cranking amps, 3 lb, a built-in jump start that saves enough charge to get you home.

Shop all Ducati batteriesWhat the ST4S needs, in plain English
Every ST4S from the first 2001 model through 2005 starts on the YT12B-BS case, a 12-volt starter battery. Ducati ships it with a lead-acid battery that starts to fade after two or three seasons of short rides and off-season storage, and that is usually the day a rider goes looking for something better.
The lithium drop-in is the Antigravity AT12BS RE-START: 360 cranking amps, 3 pounds, the same case in lithium. Its RE-START function puts the battery to sleep before a parasitic draw can drain it, then wakes it with one press for a jump start. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.
