Electric bike batteries are the powerhouses that fuel your e-bikes, providing the energy needed to run the motor and assist the rider. An e-bike battery is the single, costliest component of an electric bike, so you must take good care of it.

All electric bike batteries, or lithium-ion batteries for that matter, have a certain life specified by their “charge cycles”. Most e-bike batteries on the market are rated for 800-1000 charge cycles… but that’s not the only thing that governs an e-bike battery life.

Electric bike batteries can die prematurely without operating or storing them properly. With proper care and maintenance, e-bike batteries can remain in top condition and have a longer lifespan. In this blog, we will have a look at how to store electric bike batteries for a longer life.

How to Store Electric Bike Batteries?

Here are some of the things that help preserve battery health during storage, ensuring optimal performance when reintegrated into the bike.

Clean it up

To remove any dirt or debris, use a dry, soft cloth to wipe the battery’s exterior. Make sure there is no accumulation and that the terminals are clean. To keep good connections, make sure the contacts are clean. 

Store at the right location

Stay away from areas prone to temperature fluctuations or high humidity to prevent damage. Dust and other debris can cause interference with the connections of the battery, so make sure the storage area is clear of debris.

Avoid extreme temperatures

Look for a place to store protected from the sun, extreme heat, and moisture. The ideal environment is between 50 and 77°F (10 and 25°C) and has good ventilation. Try to unplug the bike’s battery by following the manufacturer’s instructions. 

Charge between 40-60% when storing

You should avoid storing batteries at full charge or at completely drained levels. Aim for a charge level between 40 and 60% when storing the battery for an extended amount of time to avoid overcharging or overdischarge, which can affect the battery’s long-term health. 

If the bike won’t be used for a long time, think about removing the battery for storage; however, make sure to check and recharge it regularly to keep it in good condition. 

Keep charging every few months

Ensure the battery maintains its charge by checking it every few months, even when it is stored. In case of a significant drop in the level, recharge it. Also, to avoid unintentional damage, store it in a secure location. 

Pack the battery properly

Proper packaging for storing electric bike batteries is crucial in safeguarding the battery from potential damage or external influences. 

Packaging and cases act as a barrier, shielding the battery from environmental elements such as moisture, dust, and debris. This insulation prevents potential corrosion or contamination that could compromise the battery’s performance.

Prevent vibrations

The internal components of a battery may become unstable due to excessive vibrations or shocks, which could result in physical damage or deformation… so keep that in mind while storing the battery.

In addition to loosening connections and weakening the battery shell, vibrations also raise the possibility of leaks or short circuits. Reducing the battery’s exposure to these motions helps preserve its structural integrity, guaranteeing its best performance and longevity.

Consult the owner manual

Specific battery chemistries may require a particular kind of storage. If you have any specific questions or concerns, consult the owner’s manual. When an electric bike battery is stored properly, it can continue functioning and being healthy during the inactive phase.

Periodic checkups

Regularly checking the battery’s charge level and avoiding complete discharge while storage helps extend its lifespan. Likewise, periodic inspections for physical damage or irregularities in the battery pack are also essential for its safety and longevity. 

Proper inspection is absolutely necessary to store electric bike batteries safely… and one should regularly inspect the battery for any damage, leakage, and swelling.

What Else to Know?

Maintaining electric bike batteries involves several key practices. 

Keeping the contacts clean and avoiding extreme temperatures during charging or storage is crucial. Likewise, using manufacturer-recommended chargers and avoiding fast charging excessively maintains the battery’s health. 

Managing the charge level of your e-bike battery in day-to-day usage is also extremely important. The longevity of electric bike batteries depends on how well they are charged. Maintaining the battery between 20 and 80% charge extends its life and helps prevent total discharges. 

Stress on the cells can be avoided by routinely charging after brief rides instead of waiting for a complete depletion. Furthermore, degradation is minimized by charging the battery roughly 50% when not in use.

By adhering to these guidelines, the battery’s efficiency is maximized, its lifespan is increased, and the electric bike’s power is guaranteed. 

What About the BMS?

Almost all modern e-bike batteries today come equipped with a BMS (Battery Management System) to protect the battery during charging, operations, and in periods of inactivity. The Battery Management System monitors and controls several variables, including the voltage, temperature, and charge level. 

To avoid damaging the battery during storage, a functional BMS helps prevent excessive discharging and exposure to unsafe temperatures or other external factors. Additionally, it protects against possible problems such as cell imbalances, guaranteeing that the battery maintains equilibrium throughout extended storage. 

To make sure the BMS can accurately determine the battery’s condition before storage, it is imperative to evaluate its functionality. By having the BMS checked, you can ensure that the battery is always in good shape, ready to go when needed and that its lifespan is extended. 


To store electric bike batteries, one should choose a dry, cool and well-ventilated place. Do not store the batteries in a place with high temperature or high humidity. 

Direct sunlight and moisture should also be avoided. For best results, keep the battery in an area that has a temperature range of 50–77°F (10–25°C). Besides storing the battery in a cool and dry place, storing it at around 50% charge also prevents degradation. 

As far as day-to-day operations, the battery can be kept in good condition by using the charger made specifically for that kind of battery, not overcharging, and not keeping it plugged in for long periods of time. 

An e-bike battery is the single, costliest component of an electric bike, so you must take good care of it. Taking care of your ebike battery while storing and day-to-day operations will not only increase its lifespan, but will also help improve your range
