MK Battery

have en EV Rider electric scooter which uses expensive batteries and while my scooter was under warranty I had a bit of an issue with the M&K battery that had been installed in it. It may have been an issue related to the dealer I purchased the scooter from, not M&K. when the service tech came buy to test the battery, it didn’t test poorly as it had just come off the charger. I called M&K directly and told the customer service rep, the exact symptom my scooter experienced going up a modest grade. The rep immediately determined that they would replace my batteries to the correct ones and send them off immediately.
So here I am writing to tell about my wonderful experience with this American company that makes batteries here, how delightfully painless that was,
So all of my future batteries will come from M&K to be sure, I hope this review helps someone choose a battery?
