Keeping your eBike battery topped off is simple, right? Just plug it into the wall. While that's true, with just a little extra thought and effort, you can get more from your eBike, including more range and longer battery lifespan. Check out these simple tips:
Control the Temperature
EBike batteries are best charged when it isn't too hot and isn't too cold. Avoid charging in extreme temperatures (if humans are comfortable, your battery will be comfortable too!).
Use the Right Charger
EBike battery chargers come in a variety of voltages and charging tip shapes, and are also designed to handle different battery chemistries. For best performance, use the original charger that was supplied with your eBike. If you must use a different charger (for example, if the original charger is lost or damaged and replacements are no longer available), check carefully to ensure a 100% match before you charge.
Don't Take It to 0%
Lithium-Ion batteries have the longest service life when kept at mid-capacity. Sometimes, draining your battery to 0% is unavoidable, but when possible, top off before you use every last drop. You can use the display on your eBike to monitor the battery charge level.
Don't Overcharge
You can extend the lifespan of your lithium-ion batteries by charging to 80%, when possible. While you'll only get 80% of the total potential range, that might be fine for many rides. Some batteries have LED status lights that show the charge level, and you can simply disconnect when the desired charge level is reached. Looking for an easy hack? A basic electric light timer can be used to turn off the wall current automatically after the amount of time you specify passes.
Epic ride coming up tomorrow? By all means, go ahead and charge to 100%. It's totally OK and is an expected, normal use of your battery. But if you only plan to ride 5 miles, a partial charge is a good way to maintain optimal battery health.
Keep It Dry
Never charge in a damp or wet environment. If your eBike was ridden in the rain, ensure every component is completely dry before you charge. Don't pressure wash your battery, and never submerge it.
Give It Some Room
Both chargers and batteries can get warm during use. Some chargers even have a cooling fan that turns on to help keep the charger cool by circulating air. Make sure that any vents on the charger aren't blocked and ensure that air can circulate around all the components. Place chargers and batteries on a hard surface, not carpet.
Don't Use an Extension Cord
Extension cords make electrical components work harder, because extra length adds resistance. While extension cords can be convenient, some chargers may work poorly, or not at all, when plugged into them. Plug your eBike charger directly into a wall outlet instead for best results. If you're forced to use an extension cord, use the shortest length possible, and always check the specs to ensure it can handle your charger's requirements.
Small Habits, Big Payoff
None of these tips require special tools or expertise; just a little awareness each time you plug in. Follow them consistently, and you'll get more range out of every ride and more years out of your battery, so you can spend less time thinking about charging and more time enjoying the ride.
