Posted on March 06 2018

Panasonic Kalkhoff Battery Repair Service Replacement

Do you have a Kalkhoff e-bike with a Panasonic mid-mount motor that's not lasting as long as it once did? Send in your battery to us and we will replace the cells, upgrading your capacity and restoring it to better than new! Their original specifications were 259 Wh at 25.9V and 10 Ah. We can upgrade that to 15 Ah at the same voltage for 389 Wh and 50% more range!

The Derby Cycle version below (shown for an Agattu Impulse 8 model) has a 10S 5P configuration with upgrade options up to 15Ah to give you almost 40% longer range than the original!

    @Dragan – We can’t diagnose your error codes, but you should check the voltage of your battery to see if it’s good or not.

    I have panasonic NKY317b2 battery and it stopped charging. When I press indicator key, leds run 6 times around one by one. When I press key for about 8 sec, four leds turns on and after 3 or four sec turns off. What does it mean? Is my battery dead? Thanks.

    @Amy – Unfortunately, we do not stock replacement Kalkhoff batteries, so you will need to send yours in for a rebuild.

  • Amy Benson: July 22, 2020

    I have the Panasonic 24v and would like a spare battery before I send mine for upgrade. Please tell me how I can place a battery order.

    @William – Can’t say we’ve done an Include 8 Premium before, but if it’s similar to other Kalkhoff batteries it shouldn’t be a problem.


  • William Manel: July 21, 2020

    Do you rebuild other Kalkhoff’s as well? We have an Include 8 Premium that discharged over the winter. We would love to get rolling again!

    Im Drew. I have a mid drive Panasonic 25.3V 18 AH e bike battery that’s no longer holding a charge. I would like to know the cost for a recharge or rebuild please.. The battery in the photo on your website is nearly identical to what I have. It’s a Focus Jaifra Speed model which has been an excellent product up until this point.

    Please email with pricing, time frames, payment method, etc…

    Thank you for your time and assistance-
