Can I replace the battery of my Haibike electric bike?
Yes, it is entirely possible to replace the battery of a Haibike electric bike, provided that you choose a compatible battery.
Depending on the model, the bike may be equipped with a Bosch, Yamaha, Fazua or another system. It is therefore essential to check the compatibility of the new battery with the bike model, its motor and its electrical system.
If your Haibike bike is equipped with a Yamaha battery, note down its article number and enter it into the search bar on our website to find the corresponding battery.
Is it more worthwhile to replace or have the battery of my Haibike bike reconditioned?
Reconditioning can be an interesting solution when the battery is repairable and its casing is in good condition.
Conversely, replacement may be considered when the battery is too damaged, beyond repair or cannot be reconditioned. You can then choose a new battery or a reconditioned battery, a solution that can be more economical and environmentally friendly than purchasing a new battery.
If you are unsure, please do not hesitate to contact us. We can carry out a diagnostic to determine the most suitable solution for your battery.
How do I know if my Yamaha e-bike battery is dead?
Several signs are clear indicators: a sudden loss of range, assistance cutting out while climbing a hill, or indicator lights flashing abnormally on your display. If your battery is more than 4 or 5 years old or has been stored for a long time without being charged, its lithium cells may have deteriorated.
