Invacare TDX SP Parts

This page collects replacement parts for the Invacare TDX SP power chair. We carry 24-volt battery packs, 24-volt battery chargers, foam-filled drive wheel assemblies and a leg rest hanger assembly.

The TDX SP runs on a 24-volt battery pack, listed in 22NF (55 Ah) and Group 24 (75 Ah) sizes, and charges with a 24-volt, 8-amp charger with an XLR plug. The 14"x3" (3.00-8) foam-filled drive wheel assembly also fits the Invacare 3G Storm Series and TDX SI. The model and serial number are on a label on the frame, usually under the seat. As an authorized Invacare dealer, we supply genuine OEM Invacare parts, with compatible alternatives on select items. Can't find your part? Contact us with your model number and a photo of the old part, and our team will help track it down.
