So you need a new electric wheelchair for your facility.
Maybe you're replacing an aging fleet, expanding your services, or dealing with a new patient who has complex needs. Whatever the reason, you're about to spend a significant chunk of your budget—and you want to get it right.
From the outside, it looks straightforward: find a reputable brand like Permobil, get a quote, and buy. The reality is way messier. Hidden costs, confusing battery specs, and compatibility issues can turn a smart procurement into a budget nightmare.
This checklist is for the people who sit in the procurement office, not the therapy room. It's based on managing a fleet of 20+ power chairs over six years, tracking every dime, and making mistakes you don't have to repeat.
Here's what we'll walk through:
- Step 1: Decode the Battery Specs (It's Not All About Range)
- Step 2: Calculate Total Cost of Ownership (Not Just the Purchase Price)
- Step 3: Check the Service & Repair Support in Your Area
- Step 4: Ask About the Joystick (The Most Underrated Component)
- Step 5: Verify Documentation & User Manual Accessibility
Let's go.
Step 1: Decode the Battery Specs
Batteries are the heart of an electric wheelchair, but specs can be misleading. A manufacturer might advertise a high range, but that's usually under ideal conditions—flat ground, new battery, light user.
When I was looking into the Permobil M3 Corpus, I saw it uses a specific battery type. This isn't just a detail for the technical team. It matters for your budget because:
- Battery type affects replacement cost. Some chairs use sealed lead-acid (SLA), which are cheaper upfront but need replacing every 18-24 months. Others use lithium-ion, which costs more upfront but lasts 3-5 years. The Permobil M3 Corpus, for example, often uses a 50Ah lithium-ion battery, which is a significant investment but a longer life cycle.
- Battery type affects charger compatibility. Don't assume your existing chargers will work. We had an incident where we ordered a new chair with a lithium battery, and our old chargers for SLA batteries didn't work. That set us back $400 for new chargers and a week of waiting.
Action item: Ask specifically: "What is the exact battery model and type, and what is the expected replacement cycle under normal use?"
Step 2: Calculate Total Cost of Ownership (TCO)
This is where procurement pros shine. The purchase price is just the beginning.
People assume the lowest quote means the vendor is more efficient. What they don't see is which costs are being hidden or deferred. Over the past 6 years of tracking every invoice for our rehab center, I found that the initial purchase price was only about 55% of the total cost over three years. The rest came from:
- Battery replacements: $600–$1,200 every 2-3 years for a good lithium battery.
- Joystick repairs: These are fragile. A dropped joystick can cost $300–$500 to replace.
- Software updates or calibrations: Some smart chairs need dealer visits for firmware updates, which can come with labor fees.
- Warranty extensions: A 3-year warranty extension on a high-end chair like a Permobil F-Series can be $2,000–$3,000 but might be worth it if you expect heavy use.
In Q2 2024, when we compared two offers for a new power chair, Vendor A quoted $8,500. Vendor B quoted $7,200. Almost went with B—until I calculated TCO. B didn't include the battery in the base price (charging $950 extra for the lithium upgrade) and their warranty coverage was narrower. Total with B was $9,600. Vendor A's $8,500 included the battery and a better warranty. That's an 11% difference hidden in fine print.
Action item: Build a simple spreadsheet. Ask for quotes that break down: base chair, battery, warranty, first year of service.
Step 3: Check Service & Repair Support in Your Area
This is a big one, especially for smaller facilities. A broken chair isn't just a repair; it's a lost therapy day for a patient.
I once had a joystick failure on a Friday afternoon. The nearest authorized service center for that brand was 90 miles away. Result: the chair was down for five days. The patient had to use a manual wheelchair that weekend (not ideal for their condition).
When I said "as soon as possible" to the service rep, they heard "whenever convenient." Discovered this when Monday arrived and no one showed up. That was a communication failure I won't repeat.
Action item: Before buying, ask: "How many certified technicians do you have within 50 miles of my facility? What's your typical response time for a non-emergency repair? Do you offer loaner chairs?"
For a national brand like Permobil, their dealer network is usually strong, but don't assume coverage. Get a name and a local phone number.
Step 4: Ask About the Joystick
Honestly, the joystick is the most underrated component when making a procurement decision. It's the primary interface between the user and the chair. It's also the most likely thing to break from daily wear and tear.
Back when I started in this role, I didn't pay much attention to it. I figured a joystick is a joystick. That was wrong. There's a ton of variation:
- Standard joystick: Good for most users but sensitive to vibration or accidental bumps.
- Compact joystick: Better for users with limited hand function but can be harder for other users.
- Programmable joystick: Allows for sensitivity adjustments (turning speed, acceleration curves). This can save you a headache later if a user needs a different driving profile.
Action item: If you have multiple users for the same chair, ask if the joystick is programmable. Ask for a demo of the programming software (or at least a clear manual). The Permobil M3 Corpus and similar models allow for detailed adjustments—but only if your staff knows how to use that feature.
Step 5: Verify Documentation & User Manual Accessibility
This might sound boring, but it saves time. When a new chair arrives, you need the user manual and the service manual.
I can't tell you how many times we've had to hunt down a PDF because the printed manual was lost. Specifically, when you search for something like "permobil m3 user manual," you want to find it directly on the manufacturer's site—not on a third-party download site that might have an outdated version.
Action item: Before finalizing the purchase, test it. Go to the manufacturer's website and try to find the manual for the exact model. If you can't find it in three clicks, that's a red flag. Ask the sales rep for the direct download link.
Also, check if the manual includes:
- Error codes (crucial for basic troubleshooting)
- Battery care instructions
- Cleaning and maintenance schedules
According to industry standards (and common sense), having clear documentation reduces downtime by a noticeable margin.
Final Thoughts & Common Pitfalls
Small doesn't mean unimportant—it means potential. When I was starting out, the vendors who treated my orders of one or two chairs seriously are the ones I still use for our fleet renewals. If a sales rep seems dismissive of a "small" inquiry, walk away.
Common mistakes to avoid:
- Ignoring the battery logistics: Make sure you know if you need a special charger, and budget for the battery replacement year.
- Skipping the TCO calculation: A chair that costs $500 less upfront but needs a $900 battery in 18 months isn't a deal.
- Not testing the joystick programming: Your occupational therapist will thank you for getting a chair that can be adjusted.
Procurement isn't just about buying equipment; it's about buying reliability. Use this checklist, ask the right questions, and you'll get a chair that works for your facility and your patients.
