Battery life can be a deciding factor when choosing a power wheelchair . Generally, the lifespan of a power wheelchair battery is about 1 to 3 years, and this time can vary depending on how often you use the wheelchair and how well the battery is cared for. Many people want to know how long their batteries will last and how often they should be charged to better plan their daily activities and travel.
Below we will discuss the factors that affect the battery life of your power wheelchair and how you can extend it so that you can better enjoy the comfort of your power wheelchair.
What types of batteries are available for electric wheelchairs?
There are three main types of batteries for electric wheelchairs, each with its own advantages and different lifespans:
Lead-acid batteries:
Lead-acid batteries are a traditional choice for power wheelchairs and are very affordable, but they are also heavier. They require regular maintenance, such as refilling water. If properly cared for, lead-acid batteries have a lifespan of about 1 to 2 years.
Gel batteries:
Gel batteries use a gel-like electrolyte and are completely sealed so there is no risk of leakage. They are also maintenance-free, making them a good choice for various environments. Gel batteries have a lifespan of about 2 to 3 years.
Lithium-ion batteries:
These batteries are the most advanced power wheelchair batteries you can buy. They are very lightweight, charge quickly, and have a longer life per charge. Although they are more expensive, their efficiency and longer lifespan (typically 3 to 5 years or more) make them a worthwhile investment. For example, the VOCIC V62 foldable power wheelchair is equipped with a lithium-ion battery that increases the range by 12.5 miles.
What factors influence the battery life of electric wheelchairs?
The following factors significantly influence the battery life of a motorized wheelchair:
Battery type:
The type of battery you use (e.g. lead-acid, gel or lithium-ion) will affect the lifespan of your wheelchair's battery. A lithium-ion battery will generally last longer and offer a greater range, allowing you to take longer trips, such as a visit to the park or a trip to the shops.
Charging methods:
Frequently leaving the batteries plugged in overnight can lead to accidental overcharging, which can drain the battery faster. You should follow the manufacturer's charging instructions to keep the battery in good condition.
Frequency of use:
The more you use your wheelchair, the faster the batteries will drain. If you frequently travel on uneven terrain such as gravel roads or uneven sidewalks, or have to climb steep hills, the battery will drain faster in these situations.
weight load:
The weight your wheelchair carries will also affect how quickly the battery will drain. If your power wheelchair is carrying a heavy backpack or groceries, it will require more energy to move, which will drain the battery faster.
Environmental conditions:
Leaving your wheelchair in direct sunlight or cold weather will reduce battery performance. To protect the battery, store the wheelchair in a garage or cool place when not in use, especially in extreme weather conditions.
What are the signs that the battery needs to be replaced?
Not sure when your motorized wheelchair battery should be replaced? Here are some signs of a weak battery. If any of these signs occur, the battery may need to be replaced:
Reduced range:
If your wheelchair does not travel as far as it used to after a full charge, this could indicate that the battery capacity has decreased. In this case, you should check the battery and replace it if necessary.
Slower performance:
If you feel your wheelchair slowing down or having difficulty climbing inclines that were previously no problem, this could be an indication that the battery is no longer providing the necessary power. In this case, you should consider replacing the battery.
Longer loading times:
If the batteries in your wheelchair or other lightweight electric wheelchair are taking significantly longer to charge than usual, this may indicate that the batteries are no longer holding their charge effectively. In this case, you should replace the battery in good time before a trip.
More frequent charging needs:
Even with normal use, you may find yourself needing to charge the battery more often than usual. This indicates that the battery capacity has decreased. If this is significantly affecting your travels, you should consider replacing the battery.
Battery age:
Batteries have a natural lifespan. If your battery has reached or exceeded its expected end of life (typically 1-3 years, depending on the type), it may be time to replace it.
Physical signs of damage:
If you notice that your wheelchair battery is swollen, leaking or emitting an odor, this is an emergency signal and you should replace the battery immediately to avoid damage to the wheelchair or safety hazards.
How can you extend the life of an electric wheelchair battery?
To extend the battery life of your electric wheelchair, you can follow these practical tips in everyday life:
Charging the electric wheelchair for the first time:
When your power chair or other battery-powered wheelchair comes, you should charge it for a long period of time until the battery is fully charged. This will ensure that the battery functions optimally.
Use the best charging method:
It is recommended to unplug the charger once the battery is fully charged to avoid overcharging. Also, try not to let the battery charge drop below 20% to avoid damage from deep discharge.
Store in the shade:
If you do not use your wheelchair often, you should store the battery in a cool and dry place. Be sure to keep the charge at 40-50% to maintain the health of the battery during storage.
Avoid rough terrain and keep tires inflated:
Plan your trips to avoid rough terrain and steep climbs, as these will drain the battery faster. Additionally, properly inflating the wheelchair tires can reduce the pressure on the battery.
Regular cleaning and professional inspection:
Wipe down the battery terminals regularly and check that the connections are tight and clean. This will help you use the energy efficiently. You should also have your wheelchair and battery checked regularly by a technician. They can identify problems early and ensure that the wheelchair is running smoothly.
Conclusion
In summary, the lifespan of a power wheelchair battery depends on the battery type, frequency of use, and care. To maximize battery life, you should use the correct charging method and storage method. Additionally, regular maintenance and identifying signs of wear can help keep the wheelchair running smoothly, making it safer to use indoors.
