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.

This BMZ battery is also fitted to:

Hercules, FIT E-Bike System Integration, Bulls, and Brose

. Not sure it is your battery? Compare the part number on the label with the specifications on this page.

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.

That depends on how busy the workshop is and on what we find in the intake test, so we do not quote a fixed number of days here. The current lead time is on our lead-time page.

Supercore 750 Wh (37146-00, 39078-00): re-celled at 20 Ah

The Supercore is the 750 Wh frame battery for Brose Drive S and T systems, a 36V pack of 20 Ah with type 37146-00 or 39078-00 and code P1035822. You find it on bikes including the Hercules Pasero SUV I-10, the Bulls E-Stream Evo AM 3, the Rotwild R.X750 and the Rotwild R.C750.

You keep the casing you already own and we replace what is worn: the cells. The Battery revision option here does exactly that and brings the pack back to the full 20 Ah. Select it above to see the price; the new cells carry a two-year warranty.

Has the battery stopped charging? Then send it in under Battery repair first: we test the cells and the BMS and quote before any work.
