Get Wise: How to Make Your Mobility Scooter or Electric Wheelchair Batteries Last Longer

Your mobility scooter or electric wheelchair is only as good as its batteries. Just like a car needs fuel, powered mobility equipment needs well-maintained batteries to keep you moving safely and reliably.

This handy guide from the BHTA’s Get Wise series is packed with practical tips to help you get the most out of your battery life—and avoid unnecessary breakdowns.

Why Battery Care Matters

Mobility batteries are your equipment’s fuel tank. Without proper charging habits, even the best electric wheelchair or scooter won’t perform as it should. But with a little know-how, you can extend your battery’s lifespan and keep your independence for longer.

Top Questions About Charging Mobility Batteries

💡 When should I charge my batteries?

• Always fully charge the batteries when new.
• Charge daily, even if you’ve only used the chair or scooter for a short trip.
• Never let the batteries go completely flat.

🔌 How long should I charge for?

• Charge every night for at least 8 hours.
• Aim for a 12-hour charge once or twice a month for better battery health.
• Don’t worry about overcharging—modern chargers shut off automatically when full.

⚠️ Tip: Chronic undercharging is one of the most common causes of early battery failure.

How Today’s Batteries Work

The sealed VRLA Gel and AGM batteries found in most powered mobility devices are smart, durable, and easy to maintain. Unlike older types, they don’t suffer from “memory loss”, so partial charges won’t damage them—but they still need regular full charges to perform at their best.

Quick Dos & Don’ts for Battery Care

✅ Do:

• Charge every night—no matter how little you’ve used your chair or scooter.
• Keep your charger in good condition and store your equipment in a dry place.
• Use the charger that came with your device (or a compatible replacement).

❌ Don’t:

• Let your batteries run flat—it shortens their lifespan.
• Skip charging just because the gauge says it’s still half full.
• Store your equipment with partially charged or flat batteries.

How Long Should Batteries Last?

With proper care, mobility scooter and wheelchair batteries can last 12 to 24 months—sometimes longer. Usage, terrain, weight load, and charging habits all play a role.

If you start noticing reduced travel range, more frequent charging, or slower charging times, it might be time for a battery check or replacement.
