Electric bike batteries generally last between 500-100 charges or several years, but this depends on the manufacturer, usage, and storage. Many batteries are rated for longer, including Giant EnergyPak batteries for over 2,000 charge cycles.
How Upway Tests and Certifies E-Bike Batteries Before Resale In the US

Upway’s inspection and certification process for electric bikes pays special attention to batteries. As the powerbank to your two-wheeled powerhouse, batteries must be tested to ensure reliable performance and excellent range. If our diagnostic tests reveal that the battery has less than 80% of its original capacity, we replace it with a fresh one. According to internal Upway data, only 1.06% of e-Bike batteries require replacement during the reconditioning process. These close inspections allow us to provide a full-coverage warranty and peace of mind for your next ride.
What are the indicators of e-Bike battery health?
Battery performance gradually decreases over the course of an e-Bike’s life, and certain metrics tell the exact story. Similar to how our smartphones’ batteries hold less of a charge after a few years, the maximum capacity of e-Bike batteries reduces after a while, too. Batteries typically last between 500 to 1,000 charge cycles or several years without a noticeable drop in performance, and may last even longer.
Here are factors to consider when determining battery health:
- Number of charge cycles
- Total mileage
- Battery capacity
All Upway e-Bikes are listed with information about the number of charge cycles and total distance traveled. During the reconditioning process, we use diagnostic software to confirm the battery health and replace any underperforming batteries with a fresh one.
How Upway tests and certifies e-Bike batteries
Upway mechanics use diagnostic software designed specifically for electric bike batteries to determine the capacity and battery health. For example, our UpCenters are equipped with software and hardware from Bosch to test batteries on Bosch-equipped e-Bikes, such as Gazelle, Riese & Müller, and Tern models. If a battery is determined to have less than 80% of its original capacity, we replace it with a fresh one to restore like-new performance.
Does Upway refurbish electric bike batteries?
No, Upway does not refurbish the internal parts of electric bike batteries. Instead, Upway replaces the batteries of electric bikes when necessary, though it is actually quite rare. Lithium-ion e-Bike batteries are large and are dangerous to handle when damaged, including attempting a repair and exposing the inner electrical components. Other electric bike specialists or direct brand customer support may be available in case your battery requires servicing rather than a full replacement.

Frequently Asked Questions
What’s the average lifespan for an electric bike battery?
How do I know when my e-Bike battery needs to be replaced?
Over time, e-Bike batteries gradually wear down through normal use, diminishing their capacity to hold a full charge. As a result, you’ll notice a decline in the distance your bike can travel on a single charge. While there’s no fixed lifespan, a noticeable drop in performance—especially if it affects your daily riding habits—is a clear sign that it’s time for a replacement.
How do I keep my e-Bike battery healthy?
Store the battery at or around room temperature and avoid prolonged exposure to the elements or extreme cold, which can decrease performance. For long-term storage, try to keep the charge level between 30%-80%. Charging the battery after every ride is perfectly fine, too.
Key Takeaways
- Battery replacement is rare: Only 1.06% of e-Bike batteries require swapping during Upway’s rigorous testing process.
- Data-driven certification: Upway uses diagnostic software and hardware, including Bosch systems, to measure battery health, charge cycles, and total mileage.
- Safety and reliability first: Instead of refurbishing internal cells, Upway replaces underperforming batteries to guarantee safe, like-new performance and full warranty coverage.
