15 tips for charging electric bike batteries
If you have an electric bicycle, then you know that the battery is an important part of its operation. If your battery is dead, your bike will have nowhere to go. This is why it is important to take good care of the battery and charge it properly.
To help you properly maintain your e-bike battery, I will share with you 15 battery charging tips. These tips will tell you everything you need to know. Please follow these tips, because I have to make sure that your e-bike battery can last a long time!
There is a lot of confusion about how, when, and where to charge bicycle batteries. I hope these battery charging tips help solve this problem!
Tip #1: Always charge the e-bike battery on a clean, flat surface
Your battery should always be charged on a clean, level surface. Make sure it is not placed in direct sunlight or near any place that may overheat and cause the battery to blow up.
Another suggestion: Before plugging the charger into the socket, pressing and holding the power button for about 30 seconds will not cause any harm; this will help calibrate your battery and make it more efficient.
Tip #2: Keep the bike battery away from water
Do not charge the battery in or near water. This will lead to accumulation and eventually corrosion that can lead to a short circuit! If you have limited charging space, you can plug the charger into an extension cord. This is best if the original socket is near the sink, toilet or shower.
If there is any possibility of precipitation while charging the bicycle battery, cover it with a plastic bag or tarpaulin before inserting anything. It may seem wasteful at first, but if rain even hits one battery, all batteries will be affected and the potential life span may be severely reduced!
Tip #3: Use the correct charger for your electric bike battery type
Different battery types require different chargers, depending on the voltage and amperage (or watt-hour). Many electric bicycle batteries are lithium-ion batteries, usually with 36 volts or 48 volts and 2 to 7 amps.
Lithium-ion chargers: They are very convenient because they plug into a standard 110V socket like other small appliances. Besides, they don’t have any wires coming out-all the wires are inside the charger!
To charge an electric bicycle battery, you need a charger that exactly matches the battery specifications. Before charging the battery of an electric bike, be sure to read the instruction manual for any safety precautions that may apply to your specific make/model.
Here is a “professional tip”… If other members of your family have an electric bicycle with a similar battery charger, please clearly indicate which bicycle each bicycle is suitable for. If you insert the battery into the wrong charger, it is easy to damage the battery!
Replace the battery charger
If you need to replace (or add a second) battery charger, please do the following:
Find the battery voltage and current on the back of the charger, the user manual of the electric bike, or their website
View manufacturer’s instructions on compatible content
Buy directly from the manufacturer (plan to pay more) or search for battery chargers with exact specifications.
Tip #4: Fully charge for the first time
If you are charging the battery for the first time, you should charge it for at least 12 hours. Insert it into the battery overnight and it should be ready for use in the morning. This will ensure that each unit receives a charge.
The fact is that when batteries are used for the first time, they exit “hibernation” or sleep mode (just like a computer). So they need a lot of first charge to tell them it’s time to start working. From the first charge, the battery knows how to charge it when needed, and will do so. They charge when the battery is low, but stop charging when the battery is full.
Fully charging the battery of an electric bicycle for the first time will also provide you with a good starting point to evaluate the battery life while riding.
FYI… The older electric bike battery takes longer to charge because it has less energy. If your battery has been used for several years, please pay attention to the charging time.
Tip #5: Super important tip: Check the battery level after each ride.
Check the battery level before and after each ride:
-Check it before to make sure you have enough juice to ride the expected distance.
-And check it later to determine if you need to charge it before the next ride… and make sure that if you don’t plan to ride for a while, its battery level will not drop below 30%.
Do I need to charge the battery after every ride?Most likely, you don’t need to charge your electric bike after every ride… If you do, you may damage the battery.
How often you need to charge the battery depends on several factors:
How many miles are driven per day
What is the weight of the rider
How much load do you carry
How many mountains do you have to climb
What level of pedal assist are you using
Generally speaking, more power is required when climbing mountains, carrying heavier loads, or stepping on less pedals.
A good rule of thumb is that most riders only need to charge the battery of an electric bike once a week-although this may vary by model and brand.
How to check battery usage (example):
The electric bicycle controller displays 5 “bar” battery levels. Your electric bike may show your battery level in different ways, but that’s the idea.
After a lot of riding experience, know how many miles you can ride (on a gentle hillside) and only lose one shot (if that!). I can often go to a higher gear and reduce the amount of motor assistance I use to further “one shot” charging.
But for this example, using a charging bar (displayed on the LCD controller display of the electric bike) tells you that you used about 15-20% of the battery power in a single ride. Based on this information, you can know that you can easily ride another 10 miles twice in the same week before considering charging the battery. This allows you to generally charge once a week.
So, just know how often your battery needs to be recharged is based on time and personal riding experience.
Tip #6: Charge the e-bike battery frequently for best performance
Most newer lithium-ion bicycle batteries require regular recharging.
Therefore, if you ride an electric bike 3 times a week and find that the battery power is reduced by 50-60% at the end of the third ride, then this would be a good time to recharge.
Think of it as a car battery. If your car has been parked in the garage for several weeks without being driven, it may not start when you decide to drive it again. This is because the battery has not been used.
But, of course, if your electric bike battery is not used frequently enough, you cannot charge it. Considering this charging problem, it is best to go out and ride at least a few times a week.
It is recommended that you use an electric bike as a fitness goal or at least relieve stress. You will not only take care of the battery, but also take care of yourself!
Tip #7: Fully charge your electric bike battery (from time to time)
As mentioned above, if you don’t ride an electric bike often, you won’t have as many charging opportunities. And you might think that once you ride again, you can “replenish” the battery.
However, it is a good idea to fully charge the battery from time to time. It should be done every 2-3 weeks. This will give the battery an opportunity to balance its battery and increase its long-term capacity.
Tip #8: But don’t overcharge the electric bike battery!
Since I recommend that you charge your electric bike regularly, this seems a bit confusing. But you can still charge it regularly without overcharging.
Overcharging means you:
Connect the battery to the charger for several days at a time, or
Please charge it continuously and intentionally every time the battery is only discharged by 5-10%. For example, it’s like riding 5 miles a day and then connecting it to the charger when you get home…every night.
The following will happen when the battery is overcharged: If the battery is plugged into the power source for a long time, it will naturally discharge slowly. Then your charger will determine that the battery needs to be recharged.
Therefore, your battery can only get a short charge cycle, which will consume it faster.
Therefore, if you happen to forget the new lithium-ion charger plugged into the socket while on vacation for 2 months, your battery will be affected.
This is why you don’t want to overcharge the battery: you are running out of battery life faster, and you must replace it as soon as possible!
Tip #9: Don’t drain your e-bike battery completely
Storing the battery without charging is another way to wear the battery prematurely.
If you want to use it for a long time, such as 3-6 months, you need to be fully charged at least 50% to store the battery of the electric bicycle. This will ensure that you will not have any accidents when you take out the electric bike again in spring or summer.
Tip #10: If you ride a bike frequently, charge the battery to 80-90%
Even if you ride the bike a few times a week, you don’t need (or probably shouldn’t) charge the battery to its full capacity. This actually puts pressure on the battery. In other words, you will overwork.
Charging to 80-90% is usually the way to make full use of the battery for the longest time.
Of course, if you plan to ride that may reach the mileage limit of the battery model (approximately between 20 and 50 miles, depending on the battery), please charge it to 100% before riding.
This will not cause any damage to the life of the battery, because you will naturally discharge during long-distance riding. And of course you don’t want to get stuck without charging during riding because you are worried about the overall battery life.
It’s like putting plastic on a beautiful sofa to prevent stains…it can last longer, but you will never enjoy the comfort of a sofa.
Tip #11: If you don’t ride a bike often, keep the battery low
Ideally, when you are not riding a bicycle for a while, keep the battery charge between 40% and 70%.
If you fully charge the battery while storing it, the maintenance interval will be shorter. Keeping the battery fully charged is not conducive to long-term storage and will shorten its service life.
When it is stored for more than three months, you always want it to remain partially charged in order to leave some life in the battery.
What if you store the electric bike battery without charging? You may affect performance and shorten battery life.
Tip #12: Don’t let your battery experience extreme temperature changes
The best temperature range for an electric bicycle battery is 60 to 70 degrees Fahrenheit.
This is about the same temperature as most of us (and our pets) feel good about. So use yourself as a yardstick… If too cold or too hot makes you uncomfortable, then your battery doesn’t like it either! Excessive heat or cold can degrade the battery and shorten battery life.
However, it is impractical to keep the battery between 60 and 70 degrees at all times, for example when you are out riding or when there is no air conditioning during a heat wave. But when the temperature is below freezing (36 degrees Fahrenheit) or above 110 degrees Fahrenheit, you should completely avoid charging the battery.
Tip #13: Buy a second battery charger for work or school use
Instead of feeling stressed that you don’t have enough power to go home from work or school, it is better to buy an extra charger that fits your battery. Leave the charger in the workplace or in your backpack or briefcase in case you need to recharge to go home.
Tip #14: Remove the battery from the bike and charge it (every 1-2 months)
Many electric bicycles allow you to charge the battery on the bicycle. If you can park your bicycle near a good charging socket, this is certainly convenient.
However, one way to properly store the battery is to remove it from the bicycle from time to time.
Why is this a good idea? Because you can check to make sure the connection looks clean and not sticky or corroded. Moisture, debris, and even sweat can stay there, causing poor battery connections.
Tip #15: If it is not charging, please test your e-bike battery
If you have any concerns or questions about quality or battery life, you should test it. You don’t want to get stuck on trails or long-distance riding without a working battery (electric bikes are heavy to ride without a battery).
Before testing your bicycle battery, fully charge it. Make sure it is disconnected from your electric bike. Then connect a voltmeter or multimeter to both sides of the battery.
Doing so will give you a voltage reading, which may confirm your suspicion of poor battery operation.
However, if you find that there is no problem with the battery, then you may need to check the bike’s controller.
And, if you have sparks or feel an electric shock, please put down the battery and consult your electric bike manufacturer for help!
Although they may be expensive, if your product makes you nervous, it is worth buying a new one.
