The Odyssey PC310 is a small sealed absorbed glass mat (AGM) battery built for power-sports and auxiliary use rather than starting a car. It measures roughly 5.4 by 3.4 by 3.9 inches, so it fits tight spots like motorcycle and ATV bays, snowmobile compartments and portable power boxes. AGM construction means it is spill-proof and can be mounted in more positions than a flooded battery. Against ordinary small lead-acid batteries it trades a higher upfront outlay for deeper cycling and longer shelf life, which is why owners use it for winches, trolling motors and backup power as much as for starting small engines.

Owners of small engines and power-sports vehicles generally rate the PC310 well for reliable starting and long storage life. Some complain it is expensive for its size and loses capacity if deeply drained repeatedly.
