  • 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.

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.
