Cheap 12V batteries adapted to the Renault Twizy

For a few weeks now we have finally found 12V Twizy compatible batteries without any DIY to mount them and this for a reasonable price around 70-80 € including postage, half of what Renault offers ...

They are found under the references Exide EK143 or Fulmen FK143.

For my part I had to urgently order a 12V battery and I was very satisfied with the Tayna Batteries site, battery received in 5 days for € 77.33 including delivery

Other Twizy users (whom I thank) have reported good experiences with INNPO for € 73.33 with the port and received in 4 days.
