Frequently asked questions
The price appears at the top of this page as soon as you select Battery revision (our full cell replacement) and a capacity. Shipping is included, and so is the intake test: you do not pay for it separately when we re-cell your battery. If the intake test shows that something else is needed, you get a new proposal first. Only if you turn that down do we charge the €95 inspection fee.
In a cell replacement we swap every cell in your battery for a new one. The casing and the connector stay yours, so the battery fits back in its place afterwards. Before we start, we run an intake test. If the problem is somewhere else, say the charging port or the electronics, you hear that first and get a proposal that fits. KWS Seuren has been re-celling batteries since 2017.
Register your battery on this page and follow the steps at checkout; we arrange the collection and send you the tracking details by email, with the time the courier will come. Put in the box: the printed insert form, the battery, the charger, and the key in a sealed envelope if your battery has a lock (do not tape it to the battery). Without the charger and the key we cannot test your battery fully. Your bike stays at home. Ask the courier for a proof of handover; that is your proof of shipping.
Two years. It covers the new cell pack and every part we replace during the cell replacement, including a new circuit board. We guarantee the capacity you order, not a number of kilometres. The full terms are in our warranty conditions.
Expect approximately 10 workdays from the moment your battery is booked in. The exact time depends on what we find in the intake test. You can follow the status in your own account, and the current lead time is on our lead-time page.

Polly 48V down tube battery: repair
Polly's 48V battery is mounted on the down tube and holds 21 Ah. A pack this size often fails on a single part, such as the BMS or the charging port, while most of the cells are still in good condition.
That is where our repair work comes in. KWS recovers a deeply discharged pack, fits a new BMS or circuit board and repairs the charging port. We measure the cells and the BMS, then send you a proposal with the price. Work only starts after your approval. When you say no, the battery is returned for the inspection fee stated on this page.
For this Polly battery cell replacement is currently not available.
