Electric bikes are getting quite popular for their technical advantages over traditional biking. Things like batteries, motors, and controllers make less to no use of pedaling. Batteries, being the power source of e-bikes, need the utmost care as well as the best practices in charging them.
So, how do electric bike charge?
Well, simply, remove your electric bikes’ battery pack, then connect the charger into the battery pack, plug the charger into the mains outlet, and lastly turn the switch to begin the charging.
There are many more factors that affect your e-bike’s battery charging and a lot more things that you can do to improve. So, to know everything about your electric bike’s charging, read this guide.

How Do Electric Bikes Charge?
The charging time and process of an electric bike battery actually vary based on the battery itself and its manufacturers’ guidelines. However, there are some basic steps or processes that apply to almost all types of battery charging. So, let’s take a look at those steps-
- Turn the battery switch off.
- Remove the battery pack from your e-bike.
- Connect your charger to the battery pack.
- Plug the charger into a power outlet.
- Turn on the power button.
When you purchase an electric bike, you will get several things with it. Generally, an electric bike comes with-
- The battery pack with multiple battery cells inside.
- A bay to slot the charger to connect with the battery to the bike,
- A charger with two slots.
Now that you know the charger and battery components that you’ll get with your e-bike, let’s see the detailed process of charging your e-bikes’ battery.
1. Turn the Battery Switch Off
At first, locate the power button on your bike and deactivate the battery by turning it off. You should remember turning the battery switch off every time before you keep it on a charge. This will ensure the safety of the battery while removing it.
2. Remove the Battery Pack from Your E-Bike
Fortunately, you can have an electric bike with removable battery, even with a key to release the battery. If your electric bike also uses a key to remove the battery lock, then, insert and turn it and make the lock disengaged.
In contrast, some e-bike are designed with clips or tabs to hold the battery in place. In that case, you should undo the tabs or clips and then slide the battery gently off of the bike and remove it.
It doesn’t matter how you remove the battery, make sure not to jerk or yank it while removing it. It could damage the connection of your e-bikes’ battery. Once removing it, place the battery on an even surface.
3. Connect Your Charger to the Battery Pack
As we mentioned above, if your e-bike comes with a charging adapter with two slots, now is the time to use them. One slot is for connecting with the e-bike’s battery and another slot is for connecting to the mains outlet.
Now, take the charger along with the slots and attach the one end’s slot cable to the battery of your e-bike.
4. Plugin the Charger Into a Mains Outlet
Once connecting one end of your charger with the battery, plug another slot that has the power cord into a nearby electrical outlet. Make sure, the power cord is matching the adapter port to power the battery properly.
5. Turn on the Power Button
The last step is to turn the power button. After turning on the power button, look out for the indicator light on the charging adapter. Most e-bike chargers come with a red light that turns green after the battery gets fully charged.
These are the simple steps that all you need to charge your e-bike’s battery. But, there is much more to know about e-bike battery charging. With that in mind, let’s move to the next sections.
Do Electric Bikes Charge When You Pedal?
Yes, some electric bikes get charged up when you pedal. These types of e-bikes come with a feature like regenerative braking that helps to charge the battery while you pedal. Usually, when you brake your e-bike, the energy gets lost that is produced when you pedal.
Here, this regenerative braking feature helps to save and reuse that 5% to 10% produced energy to recharge the battery.
How Long Does it Take to Charge an Electric Bike?
That’s an easy one. Simply divide your battery’s amp-hour rating by the charger’s amp rating, and the result will imply how long does an electric bike battery last. In general, depending on the chargers’ amp, a 500 watt electric bike battery will take 3.5 to 6 hours to fully recharge.
The table below will give you a general idea of the time required to charge the batteries of most electric bikes.

Do I Need to Wait for the Battery to Fully Drain?
No, there is no need to wait for the battery to drain fully. Even, it is recommended to recharge the battery before it gets out of power. If your e-bike’s battery fully discharges frequently, it can even reduce the capacity of your battery.
Therefore, instead of discharging it, try to keep the battery for charging when there is still 20% to 30% of the capacity remaining. Besides, knowing the ebike error codes related to battery will help you maintain the battery well, thus lasting longer.
Can I Stop Charging the Battery Before it is Fully Charged?
No, it is best to remove the charging slot from the main outlets after the battery is fully charged. With that in mind, you should also make sure not to overcharge your battery. Overcharging can shorten the battery’s lifespan and lead it to overheat.
Though, some modern e-bike batteries are designed with a smart charge feature that prevents the battery from getting overcharged. In contrast, if you stop charging the battery 30 minutes before it gets fully charged, your e-bike’s battery is still charged with 80-90%.
How Long Does an Electric Bike Battery Charge Last?
With a single charge, you can expect approximately 20 to 50 miles with relaxed peddling. Though, in some cases, this range can go even further to over 70 miles (112.65 km). It depends entirely on your riding style, whether you are pedaling the bike or using the throttle.
Besides that the range will vary depending on the level of assistance, battery capacity, the hills, wind, and your size. That means you can extend the range if you use little or no power while riding your e-bike on a level surface or downhill.
If you want the lifespan of the battery as a whole, we’ve discussed how long ebike batteries last before.
How Can I Make the Battery Go Further?
Typically, the electric bike’s battery lasts between 2 and 4 years if it is well maintained. Now, you know to make the most out of your e-bike and keep it in good shape for a longer time, you need to maintain it properly.
So, here are some key considerations that’ll help you to keep your e-bike battery in a good shape and last longer.
- After purchasing a new e-bike, make sure to charge the battery for 12 hours, not more than that.
- Ensure charging the battery regularly after every use, and it will last longer if you can maintain the charge between 20% to 80%.
- Don’t charge the battery for too long, otherwise, it’ll get overcharged and overheat.
- Avoid extreme temperatures and don’t let the battery get too cold or too hot. The preferable temperature is 50 °F – 77 °F or 10 °C – 25 °C.
To get a better idea, see the following table. This table covers the estimated recoverable capacity when storing your e-bike battery at different temperatures for one year.
60% (after 3 months)
- Never store your battery when it is empty or out of charge totally. Make sure it is at least half-charged or 40 to 60 percent of capacity.
- Clean the battery every time when you see any dirt, grime, or water. This will keep it functioning at its best.
Frequently Asked Questions
