If you’re not using your powerchair as much at the moment, proper battery care is more important than ever. In this article, we clear up some of the common myths and share five easy but essential tips to keep your batteries healthy – even during long periods of limited use.
Understanding Your Powerchair Batteries
The batteries used in powerchairs are very different from car batteries. While car batteries are designed to deliver short bursts of high energy, powerchair batteries (known as deep-cycle batteries) release energy slowly and consistently over a longer period of time.
At Sunrise Medical, we only use maintenance-free, gel-based batteries in our powerchairs.
-
They are completely sealed, meaning no risk of acid leaks.
-
They are safe for air travel.
-
And, as the name suggests, the only maintenance they need is regular charging.
5 Essential Battery Care Tips
✅ 1. Charge every night
Even if you haven’t used your powerchair that day, plug it in every night. Regular charging keeps your batteries healthy and ready to go.
✅ 2. Let the charging cycle finish
Avoid interrupting the charge. Leave it plugged in overnight to ensure a full recharge. (Maintenance-free batteries take longer to charge than standard car batteries.)
✅ 3. Keep it plugged in if not in use
If you’re not using your powerchair for a while, leave it connected to the charger – as long as the charger is plugged into the mains. If not, the batteries could slowly discharge.
✅ 4. If unused for over 15 days, disconnect the batteries
If you won’t be using your powerchair for more than two weeks, disconnect the cable linking the two batteries – but still do one full charge every week.
✅ 5. Check for corrosion
Look at the battery terminals regularly. If you see corrosion, clean them with a wire brush and apply petroleum jelly (not oil). Make sure all exposed parts are fully covered.
By following these simple steps, you’ll prevent a deep discharge – something that can permanently damage your batteries.
Other Important Things to Remember
-
Always pull the connector, not the cable, when unplugging the charger.
-
Place the cable where it won’t be stepped on or damaged.
-
Only use extension leads if absolutely necessary, and make sure they’re in good condition and suitable for the charger.
