As winter sets in, many mobility scooters and power chairs are used less frequently. While a little downtime is normal during colder months, improper storage or charging habits can significantly shorten the life of your batteries and even create safety risks. Whether your equipment uses sealed lead-acid or lithium batteries, a few simple steps can help keep everything safe, reliable, and ready when you need it.
Why Winter Battery Care Matters
Cold temperatures slow chemical reactions inside batteries, reducing capacity and performance. Extended inactivity can also lead to deep discharge, which may permanently damage the battery. Winter is the most common time of year we see battery issues that could have been easily prevented with proper care.
Proper Storage During the Winter Months
Avoid Storing Equipment in Garages
While garages seem convenient, they are often the worst place to store mobility equipment during winter. Temperatures can fluctuate dramatically, dipping below freezing overnight and warming during the day. These swings can:
Reduce battery capacity
Cause internal battery damage
Shorten overall battery lifespan
Better option:
Store your scooter or power chair indoors in a temperature-controlled area. A spare room, hallway, or finished basement is ideal. Aim for a consistent environment between 55°F and 75°F.
Keep Equipment Clean and Dry
Before storing your equipment for extended periods:
Wipe down the frame and battery compartment
Remove dirt, moisture, or salt residue
Make sure charging ports are clean and dry
Moisture combined with cold temperatures can accelerate corrosion.
Smart Charging Habits in Cold Weather
Charge Regularly Even If You Are Not Using It
Batteries should never sit uncharged for long periods. During winter:
Charge your equipment at least once per week
If possible, keep it plugged in between uses only if recommended by the manufacturer
Letting batteries fully discharge and sit unused can cause irreversible damage.
Avoid Charging in Cold Spaces
Charging batteries in a cold garage or outdoor area reduces efficiency and can prevent a full charge. Always charge indoors where temperatures remain stable.
Fire Safety and Charging Best Practices
Battery safety is especially important during winter when homes rely more heavily on electrical devices.
Do Not Leave Equipment Plugged In Unattended for Long Periods
Avoid charging overnight or while away from home
Unplug the charger once the battery is fully charged
Use only the charger provided by the manufacturer
Overcharging or using incorrect chargers increases the risk of overheating.
Keep Chargers Clear and Ventilated
Never place chargers on beds, couches, or carpet
Keep chargers away from flammable materials
Ensure adequate airflow around the charger during use
If you notice unusual heat, smells, or noises while charging, unplug immediately and contact a professional.
A Few Extra Winter Battery Tips
Do not allow batteries to fully drain
Avoid exposing batteries to freezing temperatures
If storing long-term, follow manufacturer recommendations for partial charge storage
Have batteries inspected if performance drops noticeably
