Top 6 Reasons Your Electric Wheelchair Battery Isn’t Holding A Charge

Battery Age and Wear

Electric wheelchair batteries are like phone batteries—they get old! Over time, they lose their knack for holding a charge. Most last about 18 to 24 months with normal use. If the battery’s older than that, it’s probably why it’s acting up.

A worn-out battery struggles to keep power. The wheelchair might cut out suddenly. This happens bit by bit, so it’s tricky to notice at first. But if charging happens more often or power drops fast, it’s time for a new battery.

Inconsistent Charging Habits

How you charge the battery matters a ton. Letting it drop to 0% and then filling it to 100% over and over wears it out quick. This messes with the battery’s insides, making it less zippy over time.

Instead, keep the battery between 20% and 80%. This keeps it happy and healthy. Regular, gentle charging helps the battery last longer. Avoiding total drains is a big key to keeping it strong.

Charging Issues

Sometimes, the battery’s fine, but the charger’s the problem. A busted charger might not give the full charge needed. This can lead to weak charging or even hurt the battery over time.

Check for loose connections or frayed wires. Look at both ends of the charger cable for any damage. Try testing the charger with another battery or check for obvious wear. If the charger’s the issue, swapping it out can fix things.

Electrical System Faults

Even if the battery seems okay, electrical glitches in the wheelchair can mess up charging or power use. Sometimes, the problem’s in the chair’s wiring, not the battery. Bad wires or broken connectors can block energy flow.

Loose wires or faulty connections stop the battery from charging right. If the charger and battery are fine but power’s still off, get a pro to check the wheelchair’s electrical bits.

Overuse or Heavy Loads

Wheelchair batteries are built for regular use with normal loads. Using the chair for super long hours or hauling heavy stuff can stress the battery too much. This kind of overuse makes it wear out faster.

Like any machine, pushing it too hard speeds up wear. Lightening the load or easing up on use can help the battery last. Avoiding steep hills when not needed also cuts stress on motors and batteries.

Temperature Sensitivity

Weather plays a big role in how batteries work. Batteries hate extreme hot or cold. Too-hot or too-cold conditions mess with the battery’s insides.

High heat can make the battery too hot, while freezing cold slows it down. For best results, keep the wheelchair in a comfy, room-temperature spot. Don’t leave it in blazing sun or chilly garages overnight.
