Mobility Scooter and Powered Wheelchair Battery care and charging.
Proper charging is the most effective way to extend the lifespan of your mobility scooter batteries and ensure your equipment remains reliable. Most mobility scooters use either Sealed Lead Acid (SLA) or Gel batteries, both of which require specific care to prevent premature failure.
1. Establish a Consistent Charging Routine
The "gold standard" for battery health is to charge your scooter after every use, regardless of how short the trip was.
• Daily Users: If you use your scooter every day, plug it in every night.
• Occasional Users: If you use it once a week, charge it after that trip and then give it a "top-up" charge once every two to three weeks to prevent the battery from self-discharging.
2. Follow the 8-to-12 Hour Rule
A common mistake is removing the charger as soon as the light turns green. Most smart chargers perform a "trickle charge" or "balance" phase at the end of the cycle.
• Aim to charge for at least 8 to 12 hours (typically overnight). Why 8 hours? A charger goes through a cycle that takes up to 8 hours and it’s important to complete that cycle each time.
3. Avoid Deep Discharge
Try not to let your battery gauge fall into the "red" zone. Frequently running a battery down to 0% causes internal damage and significantly reduces the total number of cycles the battery can provide.
4. Use the Correct Equipment
Always use the original charger that came with your scooter or a manufacturer-approved replacement. Third-party chargers may have different voltage outputs or lack the automatic shut-off features required to prevent overcharging. Avoid buying cheap chargers online as they are often poor quality.
5. Mind the Temperature
Batteries are sensitive to extreme temperatures.
• Cold: Charging in freezing temperatures is inefficient and can be sluggish, it’s rare in The UK to get extreme cold, under 4’C will reduce the range of your mobility aid
• Heat: Charging in direct sunlight or a hot garage can cause the battery to overheat.
For the best results, charge your scooter in a cool, dry, and well-ventilated room.
6. New Battery Conditioning
If you have just purchased new batteries, they require a "break-in" period. They usually reach maximum capacity after 15 to 20 full charging cycles. During this initial period, try to avoid very long or taxing journeys until the batteries have been fully conditioned.
By following these steps, you can maximise your scooter’s range and avoid the high cost of frequent battery replacements. Most importantly charge after each use (no matter how short the use was) for a minimum 8 hours. Avoid running the batteries completely flat on a regular basis.
Looking After Tyres and Pressures on a Mobility Scooter
Tyres are the only point of contact between your mobility scooter and the ground. Keeping them in top condition is essential not only for a smooth ride but also for your safety, battery efficiency, and the longevity of the scooter’s motor.
1. Monitor Tyre Pressure Regularly
If your scooter has pneumatic (air-filled) tyres, maintaining the correct pressure is the most important maintenance task.
• Check Weekly: Use a pressure tyre gauge to check the PSI (pounds per square inch).
• The Ideal PSI: Refer to your user manual for the recommended pressure. It is usually between 30 and 50 PSI, depending on the model. If unsure please contact us.
• The Impact of Low Pressure: Under-inflated tyres create more friction, which forces the motor to work harder and drains your battery much faster.
2. Inspect Tread and Surface Condition
Worn-out tyres lose grip, especially on wet or smooth surfaces like shopping centre floors or rainy pavements.
• Tread Depth: Check for "bald" spots. If the tread pattern is nearly flat, it is time for a replacement.
• Debris: Regularly inspect the rubber for embedded glass, sharp stones, or thorns that could cause a slow puncture.
• Sidewalls: Look for cracks or bulges in the side of the tyre, which can indicate age-related perish or structural failure.
3. Identify Your Tyre Type
Maintenance needs vary depending on what kind of tyres you have:
• Pneumatic (Air): Offer the best cushioning and comfort but are prone to punctures.
• Solid/Puncture-Proof: These require no air and cannot go flat, but they offer a firmer, less cushioned ride. You only need to monitor these for tread wear.
• Filled Tyres: These are air tyres filled with a polyurethane foam. They offer a middle ground—no punctures, but slightly more comfort than solid rubber.
4. Maintain Wheel Alignment and Cleanliness
Dirty wheels can lead to bigger mechanical issues over time.
• Cleaning: Use a damp cloth to wipe away mud, salt (in winter), and grit. Avoid using heavy degreasers or oil-based sprays on the rubber, as this can cause the material to degrade.
• Alignment: If you notice the scooter "pulling" to one side on a flat surface, your tyres may be wearing unevenly or the wheels may be out of alignment. Seek professional servicing if this occurs.
5. Storage Habits
If you aren't using your scooter for a long period, try not to leave it sitting on flat tyres. The weight of the scooter can create "flat spots" in the rubber. If possible, store the scooter in a way that takes the weight off the wheels, or ensure they are fully inflated before storing.
Proper tyre care ensures that every journey is as efficient and comfortable as possible. By spending five minutes a week on a quick pressure check and visual inspection, you can prevent breakdowns and extend the life of your scooter.
