This page lists replacement parts for the Merits Convertible FWD/RWD (P312/MP-3U) power chair. We carry U1 battery packs, battery chargers, an 8"x2" front caster wheel assembly, a rear flat-free drive wheel, a right motor and gearbox, a seat lift motor, a seat base cushion, a seat safety switch, a fork bearing set, armrest pads, and accessories such as an armrest pocket and cup holder.

The Convertible requires two 12-volt 35 Ah U1 batteries and uses a 24-volt 5.0 to 8.0 amp off-board charger. Several listings are named for the Merits Dualer (P312), which shares the P312 model number, and the front caster also fits the Regal (P310). The model number is on a label on the frame, usually under the seat. As an authorized Merits dealer, we supply genuine OEM Merits parts, with compatible alternatives on select items.
