As the saying goes, “cold starts from the feet”, have you felt that our legs and feet have become stiff these days, and it is not easy to walk? It’s not just our legs that “freeze” in the cold of winter, but also the batteries of our electric wheelchairs and elderly scooters.
Cold weather will shorten the journey of electric wheelchairs!
When the temperature is very low, it will affect the battery voltage, resulting in lower battery power, and the power stored in the electric wheelchair battery will also decrease. The mileage of a full charge in winter will be about 5 kilometers shorter than in summer.

How to keep the battery of the electric wheelchair warm?
Under low temperature conditions, the battery generally has the problem of poor charge acceptance and insufficient charge. Appropriately extend the charging time, and take heat preservation and antifreeze measures, so as to ensure sufficient power and prolong the service life of the battery.
1. Frequent charging, always keep fully charged
To charge the battery of the electric wheelchair, it is better to charge the battery halfway. Keep the battery in a “full state” for a long time, and charge it on the same day after use. If it is idle for a few days and then recharged, the plate is prone to vulcanization and the capacity will decrease. After the charging is completed, it is best not to cut off the power immediately, and continue to charge for 1-2 hours to ensure “full charge”.
2. Perform regular deep discharges
It is recommended that you perform a deep discharge every two months, that is, ride a long distance until the undervoltage indicator light flashes, the battery is used up, and then recharge to restore the battery capacity. You’ll be able to see if the battery’s current capacity level requires maintenance.
3. Don’t store at a loss of power
Storing the battery at a power loss will seriously affect the service life. The longer the idle time, the more serious the battery damage will be. The battery must be fully charged when it needs to be stored for a long time, and it must be replenished once a month.
4. The battery can be placed indoors when not in use, and should not be placed directly on the ground.
In order to prevent the battery from freezing, the electric wheelchair battery can be placed in a room with a higher temperature when not in use, and should not be placed directly outside.
5. The battery should also be protected from moisture
When encountering rain and snow, wipe it clean in time and recharge after drying; there is a lot of rain and snow in winter, do not ride into deep water or deep snow to prevent the battery and motor from getting wet.
