Works well in Mitsubushi PHEV
Bought this as replacement aux battery for Mitsubishi Phev. Easy fit . Works well. Just beware that it's lead acid and take care (re-) fitting the breather tube.

Had to battle with this battery
This did not fit my car as they suggested it would and I therefore had to force a fix. You see its the terminals - there needs to be a nice tight fit at the terminals and this battery has a different size to the standard. I initially used tin foil to plug the gap but then I found a piece of copper, which I had to shape, to enable the fix. In the end it all worked out well but not without some toil and sweat. Good luck.

Did not work with Tesla Model 3 Performance 2019
Worked for a week. Then Tesla reports on the touchscreen the 12v battery is low and needs replacing. After some research, I found you can change the battery type in the Tesla's service menu. Did that, ok again for another week, then same message again. Tried another Bosch battery, as it states compatible with the Model 3 Performance, exactly the same issue. Don't use this on a Tesla!

Rx400h works great!
Works fine on thr RX400H dimensions perfect! Starts ad cranks fine. Seems like the hybrid has less stress charging this hence better mpg with the traction battery. Quick dispatch and comms with the seller. Thanks
