When Is It Time to Replace Your Wheelchair Battery?
Recognizing when your wheelchair battery is reaching the end of its lifespan can help you avoid sudden breakdowns and ensure reliable performance. Common signs that indicate your battery may need to be replaced include:
- Declining travel range, even after a full charge
- Noticeable drop in speed during use
- Battery requiring frequent or longer charging sessions
- Device becoming unusually warm during operation or charging
- Unexpectedly powering off or failing to hold a charge
If you experience any of these issues, it’s a good idea to inspect your battery and consider a replacement to keep your wheelchair running safely and smoothly.
Common Battery Types for Power Wheelchairs and Scooters
Most power wheelchairs and mobility scooters rely on sealed lead-acid (SLA) batteries, which are available in either 12-volt or 24-volt configurations. These batteries are comprised of multiple cells and are designed to provide consistent, reliable power to mobility devices.
There are two main types of sealed lead-acid batteries used:
- Gel batteries: These contain a gel-like substance that holds the electrolyte in place. They are spill-proof, low-maintenance, and have a long service life, making them well-suited for frequent mobility use.
- Absorbed Glass Mat (AGM) batteries: These batteries use a fiberglass mat to absorb the electrolyte, allowing for a maintenance-free, leak-proof design. They deliver steady performance and are often favored for their durability and minimal upkeep.
While alternative battery chemistries, such as lithium-ion, are emerging in newer devices for their lightweight profiles and longer lifespans, SLA batteries remain the standard choice due to their reliability, safety, and affordability.
Typical Voltage and Amp Ratings for Wheelchair and Scooter Batteries
Most wheelchair and scooter batteries come in either 12-volt or 24-volt configurations, depending on the make and model of the mobility device. These are deep cycle batteries, designed to provide steady, reliable power over long periods. The amp-hour (Ah) ratings can vary, but common options include 18Ah, 22Ah, 35Ah, and 55Ah. Unless Specified Otherwise, the batteries you will find here are 6am or 6.6 ah batteries. Generally, higher amp-hour ratings translate to longer travel range per charge. Always check your manufacturer’s recommendations to ensure compatibility and optimal performance.
Charging Your Wheelchair or Mobility Scooter Battery for Best Results
Achieving peak performance from your wheelchair or mobility scooter depends a great deal on how well you care for the battery. Like a good cup of coffee in the morning, a fully charged battery ensures you make the most out of your day—without unexpected slow-downs.
Daily Charging Routine
For everyday users, plugging in your battery overnight is the gold standard for lead acid batteries. with the high quality Lithium Ion batteries found on this page, it is recommended to charge them when they are at least 70% drained.
Mind the Details
A few tips to keep your power supply humming:
- Charge after each use: Even brief outings can reduce charge. Topping off after every trip helps extend battery life.
- Don’t store depleted: If you won’t be rolling around for a while, fully charge the battery before storage.
- Avoid extremes: Both freezing cold and sweltering heat are no friends to batteries. Store and charge your device in a temperature-controlled environment whenever possible.
- Cleanliness counts: Wipe off dust and check for loose terminals. A bit of TLC helps stave off performance issues down the road.
Compatibility and Care
Always double-check your device’s manual for battery type and charging recommendations. Some models use standard 12V or 24V batteries (usually built from a bank of six 2V cells), but specifics can vary. Using the correct charger ensures efficient and safe charging.
A little routine care and attention go a long way toward keeping you mobile, independent, and ready for whatever’s next.
Battery Maintenance Tips
To help your wheelchair batteries last as long as possible, it’s important to keep a consistent maintenance routine. Start by storing your wheelchair and its batteries in a dry, climate-controlled space—extreme cold, heat, and moisture can quickly drain battery life. Regularly inspect the battery terminals for dirt, dust, or corrosion, and clean them with a dry cloth as needed.
Refer to your wheelchair’s manual to ensure you’re using the correct type of battery and charging it as recommended by the manufacturer (such as MK Battery or Interstate). Maintaining a regular charging schedule, rather than letting batteries fully drain, will also help preserve their performance over time.
Finally, avoid leaving the chair inactive for extended stretches without checking on the battery, and always follow the care advice suited to your specific wheelchair model.
