What the Thruxton 900 needs, in plain English

Every Thruxton 900 from the first 2004 model through 2016 starts on the ATX12 case, a 12-volt starter battery. Triumph 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 ATX12 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.

What size battery does a Triumph Thruxton 900 take?+

The ATX12 case, the same one on every Thruxton 900 from 2004 to 2016. The Antigravity ATX12 RE-START is the lithium drop-in for it.

Will a lithium battery work in a Thruxton 900 without changes?+

Yes, on a bike 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. Bikes older than about 2000 should have their voltage regulator and rectifier checked first, since a failing one overcharges any battery and lithium tolerates it less. Fill any gap in the tray with the foam spacers most lithium motorcycle batteries include.

Do I need a different charger for a lithium motorcycle 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.
