The Arctic Cat 400i takes the ATZ10 case. The Antigravity ATZ-10 RE-START is a drop-in for that case: 360 cranking amps, 2.6 lb, a built-in jump start that saves enough charge to get you home.

What the 400i needs, in plain English

Every 400i from the first 2005 model through 2005 starts on the ATZ10 case, a 12-volt starter battery. Arctic Cat 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 ATZ-10 RE-START: 360 cranking amps, 2.6 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.

What size battery does an Arctic Cat 400i take?+
The ATZ10 case, the same one on every 400i from 2005 to 2005. The Antigravity ATZ-10 RE-START is the lithium drop-in for it.
Will a lithium battery work in a 400i without changes?+
Yes, on a machine with a healthy charging system: the lithium battery uses the same case, the same posts and the same cables, and it drops in where the lead-acid battery sat. Check that the stator and regulator hold a steady charge, fill any gap in the tray with the foam spacers most lithium ATV batteries include, and match the terminal layout of the battery you are replacing.
Do I need a different charger for a lithium ATV battery?+
Use a charger or maintainer with a lithium (LiFePO4) mode. A lead-acid trickle charger can push the wrong voltage profile, and a desulfation mode can damage a lithium pack. A lithium-profile maintainer over the off-season keeps it topped without harm, and the battery loses only a few percent of charge a month sitting on its own.
