Electric bikes aren’t just a trolly to lift your weight. It plays a crucial part in the re-development portions of the world, such as environmental management.

E-bikes are great examples given by the innovatory world. They are consistently fighting with gasoline engine vehicles for their harm.

Understanding electric bikes are beginning to be a struggle for relevant consumers, as significant portions of markets are filled with gasoline parts and tools. And there are common decisive mistakes users make, such as opting to repair a battery.

Not to mention E-bike doesn’t give many errors compared to gasoline. However, several parts to keep in observation, such as the battery.

There are a few common issues with batteries found in electric bikes, but they aren’t able to get repaired in most cases and might require a replacement.

4 Common Indications Your Electric Bike’s Battery is Damaged

The electric bike battery can’t be repaired, and for valid reasons, it shouldn’t be attempted for repair. However, common indicators inform users of tentative damage to the battery. These signals affect the performance and durability of the bike. It is essential to observe these signals to make an appropriate decision. A list of some of them is below;

1.    The battery is slightly swelled.

Check the battery’s flat alignment; there might be a mild bump on the side corners or the upper surface. If the battery seems swelled, it is probably damaged by any cause.

2.    Durability

Calculate the MPC (miles per charge) and compare it with official claims, or if possible, compare it with the early day’s durability. Electric bikes’ durability doesn’t have to be affected commonly, and it happens with the gasoline engine’s average.

If the distance seems to be reducing, the battery might be damaged.

3.    E-bike is not switching on

This is a clear sign of a damaged battery. However, there must be other reasons. To conclude accurate judgment, check with other parts. If everything seems normal, the battery might be damaged and prevent the bike from switching on.

4.    Sudden speed fall

It appears when the battery is damaged, or there is a speck of dirt on the magnets. If the speed tends to fluctuate, the battery might be damaged, causing the bike to spare its potential.

How to Check your E-bike battery? 4 Viable Methods

Fixing a battery is throwing an arrow in thin air. That is because it is always an excellent choice to replace the pack. However, not necessary to do so in case of minor damages such as a damaged wire.

There are plenty of primary diagnoses to assure your electric bike performance, as listed below;

1.    Load the battery

It happens not just with the e-bike battery but with phones and other gadgets. There might be minor fluctuations in the electricity supply. Sometimes the battery is not charged with full voltage and thus performs weakly.

Charge your battery for 24 hours (if suitable) and ride it until it drains completely. During this diagnosis ride, you might want to create a checklist comparison for the MPC and speed stability.

2.    Test the current by PDH

Power discharged per hour. This is an authentic way to check the battery’s health. It is done by analyzing the amount of energy your battery is taking in an hour frame of charge. It goes with both indirect and direct proportions.

First, check the PDH for charging, and then it must check PDH for its discharge. The difference in digits indicates damage to the battery. Or, if the battery is too bad to use, it will discharge as quickly as a bird flap.

3.    Voltage test

It is amongst the most professional and authentic ways to check the battery. Revise the official voltage usage of the battery on the pack or the user guide for your electric bike.

Then you need to have a multimeter for a connection with the battery and set the multimeter to voltage. The results shall be seen after a good while of charging. The voltage in the multimeter should match the voltage in the user guide or battery pack.

If the voltage is significantly lower than the official claim, the battery might be damaged and require a replacement.

4.    Go through the BMS

Battery management system. It is used by active enthusiasts. This method is used to check the individual cell performance in the battery. An electric or hybrid vehicle’s battery has a bunch of cells that work together to provide the full capacity.

It is done by charging the battery at first. Moving on to disconnecting the cord after a full charge, then putting a reasonable load on the battery. Further to connecting multimeter’s plug-outs to each cell during battery consumption by the load.

The number of cell power will appear on the multimeter’s screen, and by checking each cell continuously, you will get to know the pendulum of power. If the battery is damaged, some cells might show instant drainage.

Preventing your Electric Bike Battery from Getting Damaged

Electric bikes might not require costly maintenance, but it does require keeping an eye on their health. There are a few precautionary ethics you can follow to maintain good battery health in the future, as listed below;

1.    Keep the battery in a calm environment.

Lithium batteries are sensitive to external temperatures. Most damaging events occur in summers due to battery exposure to the hot sun. Avoid parking your bike under direct bright sun.

2.    Avoid full drainage

Do not get rid of each cell of the battery. It weakens your e-bike battery when it’s frequently drained completely.

3.    Avoid using aftermarket chargers.

Markets are yet to get access to secondary tools for electric bikes. Only use an officially claimed battery charger to avoid costly damages.

Conclusion

The verdict goes for a replacement. Electric bike batteries aren’t meant to be repaired. Instead, they should be replaced by a new pack or battery. It is due to contagious damages to other parts of the bike.
