Step-by-Step Battery Replacement
1. Prep & Safety
Power OFF the wheelchair and remove the key if applicable.
Find a well-lit, dry surface—ideally a garage floor or driveway.
Because batteries are heavy, have someone assist you.
2. Locate & Open Compartment
Open the battery compartment—typically under the seat or at the rear. It may have a latch, screws, or slide release.
3. Disconnect Batteries
Identify the battery packs (usually two, side by side).
With a wrench, loosen and remove the negative (black) terminal first, then positive (red).
Carefully unplug the battery hog‑tail or connector.
4. Remove Old Batteries
Remove each battery pack one at a time—these can weigh ~10–20 lb each.
If your wheelchair uses internal batteries in cases, unclip and open the casing, then swap them out.
5. Install New Batteries
Place the new batteries in the same orientation as the originals (terminals facing correctly).
If inside cases, re‑clip the casings securely.
6. Reconnect Terminals
Reconnect the positive (red) terminal first, then negative (black).
Make sure bolts are snug—but don’t overtighten.
7. Close Up
Close the compartment securely.
Ensure any covers, screws, or latches are properly fastened.
8. Power On & Test
Turn the chair’s power back on.
Check operation and battery indicator lights.
Fully charge the new batteries before regular use.
Pro Tips
Charge after each use to maximize battery lifespan.
Always store batteries charged, and in a cool, dry place.
Recycle used batteries responsibly—many retailers or service centers accept them.
