Maintenance schedules differ by model and manufacturer. The daily/weekly/monthly/yearly structure, cleaning rules, and storage guidance come from the Permobil M5 Corpus user's manual; battery-charging rules from Sunrise Medical's powerchair guidance. Always follow your own model's manual and your dealer's instructions. Checked 1 Oct 2026.
In brief
- Permobil structures maintenance into daily (battery indicator, joystick, fastenings, belts), weekly (tyres, lights), monthly (cleaning, upholstery, brake release), and an annual authorised-dealer inspection.
- Charge batteries every night, let each charging cycle finish, and watch for terminal corrosion — a deep discharge can permanently damage the batteries.
- For storage, fully charge first, keep the area dry, and recharge on the manufacturer's schedule; call your authorised dealer for anything broken, loose, or unclear.
Daily: battery level, controls, and fastenings
Permobil's user manual for the M5 Corpus recommends these daily checks: look at the battery level indicator and charge if necessary; check that the joystick panel and other control panels are not damaged; make sure all removable parts are securely fastened; and check positioning belts for wear while confirming the buckles work. These take a minute or two and catch the problems most likely to ruin your day — Permobil cites a 2017 survey of power wheelchair users in which 56% had parts break or malfunction, with the battery, armrest, and lift/tilt function the most commonly reported. Permobil asks users to follow its recommended schedule and to contact an authorised dealer for anything service-related.
Weekly: tyres, lights, and a quick clean
On a weekly basis, the Permobil M5 Corpus manual recommends checking the tyres and inflating as necessary, and if the chair has lights and indicators, making sure they are operational and clean. Permobil's maintenance blog adds the wider weekly habit: clean the chair often, inspect it for wear and tear, tighten hardware such as headrest and seating components, inspect seating components like cushions and back supports, and adjust as needed. A regular clean is also your early-warning system — as Permobil puts it, inspecting as you clean is how you spot loose or worn parts before they fail.
Monthly: upholstery, seating, and brake release
Once a month, according to the Permobil M5 Corpus manual: clean the wheelchair and upholstery; check the upholstery, seating, headrest, arm pads, and calf pads for wear; and check that the brake release and the brake release lever work properly. Cleaning rules from the same manual: always switch the power off before cleaning; wash metal surfaces with a soft cloth or sponge, hot water, and a mild detergent; wash plastics with a soft cloth, mild detergent, and hot water — never use solvents or abrasive kitchen cleaners; and wash upholstery with lukewarm water and a mild, nonabrasive soap. Using an unlisted cleaning method can degrade vinyl and may void the chair's guarantee, according to the manual.
Battery care: the part that fails most often
Batteries are the single most commonly failed part in the survey Permobil cites, so charging habits deserve their own routine. Sunrise Medical's battery guidance for its powerchairs — which use maintenance-free, gel-based batteries — gives five rules: charge every night, even if the chair was not used that day; never interrupt the charging cycle, so leave it plugged in overnight; if the chair will sit unused for a while, leave it connected to the charger as long as the charger is plugged into the mains; if unused for more than 15 days, disconnect the cable linking the two batteries, but still give a full charge every week; and regularly check the battery terminals for corrosion — clean any with a wire brush and re-grease with petroleum jelly, not ordinary oil. Also pull the charger connector rather than the cable, and route the cable where it cannot be stepped on. For storage, Permobil's manual adds: do not store the chair where condensation forms; battery life depends on regular charging and avoiding complete discharge; for long-term storage, fully charge before storing, switch off the main circuit breaker, and recharge stored batteries every 6 months. Note the schedules differ because they cover different situations — follow the manual for your own model, since acid batteries, gel, and AGM batteries each have their own rules.
Annual: book the full dealer inspection — and call sooner when in doubt
Once a year, the Permobil M5 Corpus manual calls for a complete inspection, safety check, and service performed by an authorised wheelchair dealer. Permobil's maintenance blog echoes the principle behind it: be proactive with replacement components, including batteries, and contact your service provider when something changes — for example, if the battery no longer charges the way it used to — before a worn part leaves you without mobility. If you find any broken or loose component, discontinue use and contact your authorised dealer rather than improvising a fix. And if you are ever unsure what a noise, warning light, or handling change means, that uncertainty itself is the signal to call a qualified technician.
