Battery Charging Issues

Okay, so your electric bike battery life drains really quickly, or it won’t charge at all. You could just scrap the whole thing, throw it on a junk pie for someone to rejoice over, or you can try to diagnose and treat the problem.

The first thing you will want to do is diagnose it as an error in the battery or the charger. You will have to remove the battery pack from the power lines that connect it to the bike itself. You will want to make sure the charger is plugged in and hook it directly to those power lines and try to start up the bike. If the dash lights up or the wheels spin, you will be certain that it is a battery issue and not the charger.


You can get a whole new battery, which would be our suggestion, or keep using your failing battery and hope it does not entirely give up on a busy street.

If, however, the problem seems to be with your charger, we would suggest just getting a new one entirely.

So these are common problems faced when diagnosing your electric bike battery life problems. Often, it is a charging issue. But what if your ebike battery life isn’t the problem? What if you have discharging issues rather than charging issues?


For example, what if your electric bike discharges the battery too quickly, or you aren’t given an accurate measurement of the percentage discharged thus far?

Sometimes, the fix may be as simple as disconnect, then connect again. If a battery that you know is charged is reading as drained on the first glance, this may be the only thing you need to do. Very often, when a battery is connected the first time, a few wires may have gotten crossed, giving you a false reading. If you quickly reset the connection, they should have straightened themselves out.


Have you tried to reconnect your battery over and over again, but it tells you that your ebike battery life is gone, you may have to go back, you might have a battery or a charger issue.


If you are just facing some mysterious, but serious matters, it may be helpful to invest in a voltmeter. A voltmeter will tell you just how many volts your battery is capable of discharging at a given time. If you feel that your e-bike battery problems are graver than you have the know how for, a voltmeter is an indispensable instrument for you.


Not only can a voltmeter tell you exactly how many volts your battery expends, it tells you how much it can hold. This is great for timing your charging down to the minute, as well as deciding how many miles you can get out of one charge. A voltmeter measures the electrical potential difference between two places on an electrical circuit. Enough of that mumbo-jumbo, it can tell you exactly how big your battery is. You’ll never be in the dark about the capabilities of your battery ever again.

Riding an electric bike is wonderful for many of us. It does not require the stamina that traditional bike riding demands, but it’s still out in the nice, fresh air and it is less of a hindrance on our environment than other forms of transportation. In large, crowded cities electric bikes are quickly becoming the norm, with many large name producers of automobiles looking to get in on the adventure. One advantage of having a lot of famous manufacturers now producing electric bike is that now, you can get your electric bike serviced in many new places.


In much the same way, if you feel like you need a new battery or charger or other accessory for your electric bike, they are now much easier to find. As electric bicycles become more popular, and the market for them expands, so do the cosmetic options. An electric bike used to be something utilitarian, in drab color schemes and boxy silhouettes. Now, however, you can purchase an electric bike in just about any color you can imagine, with a matching battery pack and charger to keep the design cohesive. The amount of accessories now available also boggles the mind. There are baskets, saddle bags and just about anything your heart could desire to customize your dream mode of transportation. It’s like a utilitarian edge mixed with a fashionista flair.
