Shop all Harley-Davidson batteriesWhat the Street Glide Ultra needs, in plain English
Every Street Glide Ultra from the first 2025 model through 2025 starts on the YIX30L-BS case, a 12-volt starter battery. Harley-Davidson 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 ATX30 RE-START: 880 cranking amps, 6 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.
