MyLaps Flex Battery Replacement Kart Transponder

Battery replacement

If your MyLaps FLEX transponder no longer charges the battery may need replacing.

This is a battery replacement service only for SUBSCRIPTION transponders.
We do not test the transponder in any way and do not give any guarantee the transponder will function correctly with a new battery. We do not offer a refund if the new battery does not fix the problem with your transponder. 

We recommend you check if your transponder is within subscription before sending it. 

To use our service

first pay, using the “Buy It Now” button.

We aim to turn around your transponder within 5 working days, but can take longer. 

NOTE FOR NON-EC CUSTOMERS - your defective transponder does not have any value. If you put a value of a new replacement on the customs label I will be invoiced for UK import duty, which is about £50. I will reject the bill and the transponder will be returned to you - this will take several weeks.

Therefore please remember a defective transponder has very little (under £5) value and fill in the customs form appropriately.

NOTE - when we return your transponder it can only be insured for the cost of repair, not the value of a replacement transponder.
