There are a few ways to recharge a wheelchair battery, even though it may appear to be a useless piece of equipment—your inquiry about whether you can revive dead electric wheelchair batteries in a few ways today.
You can get back outside and live fully once you’ve recharged your wheelchair battery. If you’ve ever had to charge a wheelchair battery, you know how challenging the procedure may be.
Fortunately, charging the battery only requires a few easy steps.
I’ll review the steps involved in charging a wheelchair battery in detail and recommend how to do it as quickly and painlessly as possible.
Can you revive dead electric wheelchair batteries?
Even when a battery has had numerous discharges and recharges and is now dead, that doesn’t mean it can’t be recharged. As a result, a dead wheelchair battery cannot be recharged with a charger plugged into a 120v power outlet. Only a battery pack, a portable jump starter, or a pulse charger can recharge a dead wheelchair battery.
Before they fail, most batteries can only be discharged so many times. A battery may only partially recharge if it has been fully depleted too frequently.
Most dead batteries can be revived with a pulse charger since it charges the battery differently from a regular charger.
Connect the pulse charger to the battery in the same way you would a regular charger to use it. The subsequent charging cycles should only take an hour or so after the initial charging cycle, which could take many hours.
You should replace your battery if your chair uses less than half its maximum speed after being charged or if it is depleting quickly.
A dead wheelchair battery can be recharged with a battery pack, but it should be replaced if it is too old or damaged.
If you want to recharge the battery using a battery pack, you’ll need to disconnect it from your charge and connect it to the pack.
Before taking the batteries from their chargers and repositioning them in their original locations in the wheelchair, let each battery finish charging completely.
Batteries are given a boost via jump starters. Jump starts provide a brief power boost to a weak or dead battery instead of a car battery charger, which recharges a dead battery.
Connect the positive terminal of your wheelchair’s battery with the red jumper wire, an unpainted metal surface on your wheelchair, and a car battery, if you’re using a portable jump starter to power a dead wheelchair battery.
The jumper cables will carry some power to your dead battery and turn it on once the automobile is started.
Is it necessary to change a dead wheelchair battery?
The best course of action, if you intend to use your wheelchair is to get replacement batteries if a dead battery cannot be revived using a pulse charger, jump starter, or battery charger.
A battery generates power as a result of internal chemical reactions. Additionally, there is no alternative method to restart this chemical reaction after it has stopped.
If your battery dies while still under warranty, you can get a new one for nothing.
If not, evaluate the circumstances and decide whether it would be better to spend money on a new battery or a new wheelchair.
How to Recharge a Dead Battery in an Electric Wheelchair?
You can take a few different routes to attempt and recharge the wheelchair’s dead battery. You have three options for charging it: utilizing another battery pack, a pulse charger, or hiring a professional.
It is crucial to understand and practice the best charging procedures for wheelchair batteries because, with the right maintenance, you may be able to increase the lifespan of your wheelchair battery pack by up to two years.
Good Battery Care Advice
The guarantee period for most wheelchair batteries is one year. Therefore it could not cover the entire battery’s lifespan. Here are some pointers for proper battery maintenance:
- Read the user instructions for your wheelchair. It ought to include advice on battery maintenance and steps you may take to make sure you can safely operate your wheelchair, including battery maintenance.
- It may take up to 10 to 12 hours to completely charge your new wheelchair before your first use. ChargeCharge the battery overnight if possible, but remember to unplug it after 12 hours.
- It would help to be careful not to deplete your batteries by more than 30 to 40% during the first two weeks of use.
- This may limit your activities, especially if you use your wheelchair to get to work every day and don’t have a car, but doing so can assist in maintaining the battery of your wheelchair over time.
- Even if batteries weren’t used much throughout the day, charging them every night for a substantial amount of time (at least 6 hours) is still preferable.
- Always use the battery charger that was included with your smartphone. Try to obtain the manufacturer’s original charger for sale if you need a new battery charger since the one that came with your wheelchair is broken.
- You shouldn’t use up more than 80% of your battery power. Your battery’s life can be shortened by deep discharge.
- Unlike nickel-cadmium batteries, lithium-ion batteries do not have a battery charge memory. Thus you do not need to discharge and recharge them.
- Batteries should be kept at room temperature. High or low temperatures can significantly affect battery life.
Despite our best efforts, wheelchair batteries may occasionally get entirely dead owing to prolonged inactivity (In the event of extended inactivity, it is recommended that the wheelchair’s battery be removed) or complete depletion while in use.
Batteries occasionally experience a progressive depletion after being deeply discharged. In these circumstances, it is impossible to recharge your batteries using the standard charger that came with your device.
If your batteries are still covered by their warranties, you’re in luck since you can get them changed. The following techniques can be used to recharge your wheelchair battery, though, if the warranty has expired.
How to Recharge a Dead Wheelchair Battery on Your Own?
The purpose of this technique is to deceive your device charger into charging the battery down. The following equipment is necessary; you either already have it at home or can buy it online or in a store.
The lithium battery
A functional lithium battery with a high enough voltage capacity is ideally analogous to a dead battery. The second battery with identical characteristics will be the greatest option.
This wheelchair battery could serve as your backup.
However, the likelihood is that both batteries would be dead if you had been using both batteries simultaneously.
- connecting the batteries to the charger via jumper cords
- Voltmeter for voltage measurement
- Timer (often found on cell phones)
- the battery charger that came with your gadget
The charged battery that is in use and the dead battery is first linked in parallel, with the positive end of each battery attached to the other and vice versa.
It’s crucial to remember that, at this point, the charger shouldn’t be attached to the batteries.
If the charger is connected and turned on, there can be sparking.
However, sparking can be prevented if the positive connection is connected first.
Connecting the charger to the healthy battery is the second step. The dead battery will now begin gradually charging through the healthy battery.
You should constantly monitor the process to look out for any unfavourable situations. You should see if the exhausted battery is heating up after about an hour and as often as possible.
If the battery gets hot or makes a hissing noise, you should turn off the procedure immediately.
Heating up indicates that the battery cannot be revived, or there may be another issue.
Additionally, you should keep checking the voltage of the drained battery with your voltage meter to see if it has at least reached 10.5 volts.
The ideal timing for this is between one and two hours. When this occurs, removing the healthy battery from the device is best.
Only the dead battery should be connected to the charger after you correctly disconnect the charger and remove the good battery.
After that, you should keep charging the dead battery until it is fully charged.
Follow your charger’s indication when it says it’s fully charged; otherwise, you should ideally maintain checking the voltage with a voltage meter.
A fully charged battery should be ready in three to five hours.
While the aforementioned is a clever approach to recharge your completely dead battery, it is strongly advised that if you are a wheelchair user, you undertake this activity under supervision or with assistance from family members.
You need not panic if you discover you can revive dead electric wheelchair batteries. Using a pulse charger, you or a competent technician can revive your battery instead of replacing it, depending on the state of your battery.
Last but not least, it’s crucial to properly dispose of the dead battery if you’ve decided to replace it with a new one.
Batteries left lying around after disposal have a harmful influence on the environment because of lead discharge.
If your city or municipality has a program for getting rid of used batteries, inquire about it. Additionally, you can hunt for battery recycling facilities.
There are also battery-specific shops that might offer you a modest sum for a dead battery in exchange for the parts that they can rescue.
This page is meant to assist you in recharging your wheelchair’s dead battery. We hope the battery in your electric wheelchair lasts a long time!
How can I tell if the battery on my wheelchair is dead?
By checking the voltage of your wheelchair battery using a digital multimeter or voltmeter, you can determine if it is dead. A 12-volt AGM wheelchair battery that has been fully charged should display 12 volts or greater. Any reading below 11.6 volts on the voltmeter indicates that the battery might need to be charged. It must be changed if the voltage reading is less than 10 volts, indicating it is fully dead.
