Hi Yes it fits perfectly, but only after you cut off (dremel or hacksaw) the extra plastic moulding which sticks out around the base of the battery. Make sure you unclip (not unplug) the temp sensor from the old battery before removal. Wen you put the new battery in you can put the temp senor anywhere you like nearby (duct tape it on top of the battery if you wish!) as it is only there to sense the temp of the area around the battery in any case. As you do not need to unplug it at any point so you will not get a code or any other issues.

Please could you point me in the direction of the person you used, KayCee?

Hi I had this exact issue on my Mk4 2012 GS450h. I bought this and it fitted and worked fine: GENUINE TOYOTA 12V BATTERY 60AH L2 STARTER BATTRY 28800-YZZZA 2007-2018 I now have another Mk4 , 2017 GS450h with the exact same problem so have bought another one. It cost me 80 quid, but now they are 124.99. Fitting it this weekend. If you buy from their you will need to give them a fake reg as they won't supply it for our vehicles as they say it won't work. But it does.
