Common Electric Bike Battery Issues and Solution

Electric bikes are becoming increasingly popular for a good reason. You have probably seen them whizzing past on your commute or scenic trails. Is It Worth It to Buy an Electric Bike? E-bikes provide a powerful and eco-friendly mode of transportation, boasting impressive statistics that are difficult to ignore. More people are opting for e-bikes for commuting, running errands, or leisure, which helps reduce our reliance on cars and decreases our carbon footprint.

Leoguar understands the importance of a reliable battery on your ebike. However, while e-bike battery technology continually improves, even the best batteries can sometimes face challenges. Join us as we explore common electric bike battery problems and their solutions to keep your ride smooth and hassle-free.

What Are Common E-Bike Battery Issues, and How Do We Troubleshoot Them?

Just like a dwindling phone battery, e-bike batteries are no different. Let's explore some of the most frequent problems and how to get you back on the road confidently.

Reduced Range: When Your E-Bike Doesn't Go the Distance

Have you noticed your e-bike failing to reach its usual range? This can be a real buzzkill, especially if you count on that extra boost to get you home. Before getting stranded miles away, let's diagnose the potential culprit. 

Diagnosing Battery Problems

  • Monitor Range Performance: Track your typical riding distance on a full charge. Has there been a gradual decline, or is it a sudden drop? This information helps narrow down the cause.
  • Check for Physical Damage: Like any e-bike component, the battery can take a beating. Inspect the casing for cracks, dents, or leaks. Visible damage is a red flag and may necessitate a battery replacement.


  • Proper Charging Practices: Believe it or not, improper charging can significantly impact your battery's health. Always use the manufacturer's charger and avoid exceeding the recommended charging time. Unplug your Leoguar e-bike once the indicator light shows a full charge.
  • Regular Inspection and Cleaning: Regular maintenance is essential to the health of your battery! Wipe down the battery terminals with a dry cloth to remove any dirt or corrosion that might impede proper electrical connection. Consult your Leoguar user manual for specific cleaning instructions.

Slow Charging: When the Wait Feels Eternal

If you need to hit the road but your once-speedy charger takes an eternity to charge your e-bike, don't fret! Here are some ways to diagnose and address the issue. 

Diagnosing Battery Problems

  • Monitor Charging Time: Time how long it typically takes for your battery to reach a full charge. Has there been a noticeable increase in charging duration?
  • Checking Connections: Loose or corroded connections between the charger and the battery can hinder charging. Visually inspect the connection points for any damage.


  • Using the Right Charger: This may seem obvious, but ensure you use the charger specifically designed for the Leoguar e-bike models. Mismatched chargers can lead to slow or incomplete charging.
  • Avoiding Overcharging: While it might be tempting to leave your e-bike plugged in overnight for "good measure," resist the urge! Overcharging can damage the battery and shorten its lifespan. Once the indicator light signals a full charge on the Leoguar Rambler, unplug it!

E-Bike Battery Degradation: The Inevitable (But Manageable) Decline

Just like any rechargeable battery, e-bike batteries will naturally degrade over time. The 48V15Ah (720Wh) on your Leoguar Strider battery powered bike is bound to reduce capacity with time. The good news is that you can significantly extend its lifespan with proper care. That is what we are here to help you achieve.

Diagnosing Battery Problems

  • Monitoring Capacity: Pay attention to how long a single charge lasts compared to when the battery was new. A noticeable decrease in range indicates potential degradation.
  • Assessing Performance Over Time: Does your e-bike seem to struggle to maintain power on inclines or experience a quicker drop in battery life? These signs suggest the battery might be nearing the end of its useful life.


  • Maintenance Tips: Proper charging habits and regular cleaning can help preserve your battery's health. Avoid extreme temperatures when storing your e-bike, as hot and cold environments can accelerate degradation.
  • Battery Replacement and Upgrades: Even with the best care, batteries eventually reach a point where replacement is necessary. Leoguar offers high-quality replacement batteries specifically designed for your e-bike model. Depending on your riding needs and technological advancements, consider an upgrade to a higher-capacity battery for extended range.

Troubleshooting Battery Problems

The first step is to diagnose the problem. Think about your recent riding habits. Has your typical riding distance on a full charge decreased noticeably? Are charging times taking significantly longer than usual? Notice any unusual behavior from your e-bike, like reduced power output on inclines? Make a mental note of these observations.

Next, take a closer look at your battery itself. Is there any visible damage like cracks, dents, or corrosion? These signs could indicate internal issues affecting performance. Finally, gently inspect the charger and connection points. Are all connections secure and free of debris? Loose connections can disrupt the flow of electricity and hinder charging.

How to Resolve Issues

Once you've gathered your clues, it's time to take action! If you suspect a charging issue, verify you're using the charger that came with your e-bike. Using an incompatible charger can damage the battery and slow down charging. Also, ensure all connections are snug and free of dirt or corrosion. A simple cleaning with a dry cloth might be all it takes. 

If you are concerned about reduced range, it’s likely due to your charging habits. Are you following the manufacturer's recommendations? Overcharging or undercharging can shorten battery life. Remember, it's not always about the miles you ride but how you treat your battery.

If you need help or the problem seems more complex, consult your e-bike's user manual or contact a qualified service technician. They can provide expert advice and ensure your e-bike continues to deliver a smooth and enjoyable ride.

Maximizing Your E-Bike Battery's Potential: Essential Tips

It’s important to get the most out of our e-bike batteries, extending their range and optimizing performance. Leoguar focus is on creating e-bikes that go the distance. But beyond the technology we build in, your riding habits can significantly impact battery life. Let's explore some key strategies to transform you into a battery-conscious rider:

1. Pack Light

Think about it this way – the more weight your e-bike carries, the harder the motor has to work. Avoid overloading your e-bike with unnecessary cargo. Plan your rides and only bring what you truly need. Every pound shed translates to increased efficiency and a longer ride.

2. Finding Your Rhythm

Those high-speed bursts may be exhilarating, but consistently riding at maximum speeds will drain your battery more quickly. Develop a smooth, steady riding pace. You'll be surprised how much further you can travel when you find your e-bike's sweet spot.

3. Conquering Hills Strategically

Hills can be challenging on any e-bike battery. But that doesn't mean you have to avoid them altogether. Here's a trick – as you approach a climb, shift to a lower gear and provide some additional pedal assist. This teamwork between your legs and the motor minimizes strain on the battery, helping you conquer those inclines without sacrificing too much range.

4. Embrace the Power of Your Legs

E-bikes are a blast, and the pedal-assist feature is undeniably tempting. However, still make use of your legs! Incorporating good old-fashioned pedaling on flat terrain or gentle inclines gives your legs a workout. It reduces reliance on the motor, preserving battery life when you need that extra boost.


E-bike batteries are the heart of your electric adventure. Understanding common battery issues and implementing these troubleshooting and maintenance tips ensures your e-bike keeps pace with your exploration. Remember, a well-maintained battery translates to a longer lifespan, optimal performance, and, ultimately, more miles of electric enjoyment. So, charge up your knowledge, embrace these practices, and get ready to conquer the road ahead!
