Special advices for the use of Li-ion batteries after ebike battery rebuild and repair by replacing Li-Ion energy cells with new ones.
How to correctly start using a restored Li-Ion battery after ebike battery rebuild and repair by replacing Li-Ion energy cells with new ones?
There's an important aspect when beginning to use a restored Li-Ion battery after ebike battery rebuild and repair.
Every new Li-Ion element installed in the battery goes through 2 cycles from full charge to full discharge during testing. However, this isn't enough for the elements to reach their maximum capacity and "seal" their memory. So, after receiving the battery, it's important to properly "break it in" to achieve its maximum capacity. To do this, you need to charge the battery to 100% without interruption (the restored battery is sent to you charged to 50-60%).
Then, while riding your bike, fully discharge it to 0% until the assistance stops without intermediate recharging!
After the full discharge to 0%, you should promptly (within a few hours) put it on charge and charge the battery to 100% without interruption. This full cycle from full charge to full discharge without breaks in charging should be repeated 2-4 times in a row. After this, the battery will reach its maximum capacity and can be used in normal mode.
In the future, to extend the battery's life, it's advisable to periodically repeat such full charge-discharge-charge cycles.
What are the characteristics of the battery charge level indication after ebike battery rebuild and repair?
During the ebike battery rebuild and repaire we install new high-capacity Li-Ion elements in the battery. As a result, the battery's capacity often becomes higher than it was during its manufacture. Therefore, the bike's computer may not always accurately display the battery charge level on the indicator – this is a normal occurrence.
On many bike brands, the computer "learns" over time, and the battery charge level indication becomes more accurate. You can speed up this "self-adaptation" of the computer by repeating full discharge cycles from 100% to 0% several times.
But unfortunately, on some bike brands, this self-learning doesn't occur. In this case, you need to get used to correlating the actual remaining mileage of the bike with assistance with the indicator's charge level readings.
What is the expected approximate service life of a restored battery after ebike battery rebuild and repair?
After ebike battery rebuild and repair the average service life of a battery before its capacity drops to 50% is approximately 4-8 years, depending on storage conditions, maintenance, and usage intensity.
General recommendations and tips for storing, maintaining, and using Li-Ion batteries are here.
In the first 2 years of use, new Li-Ion elements may undergo normal natural degradation of 8-15% per year, depending on conditions and usage intensity. Usually, the capacity of the elements decreases more quickly in the first 2 years than in subsequent years.
