Does the Aygo X get the same battery as the Toyota Yaris hybrid?

Will the new Toyota Aygo X have the same 12-volt battery as the Yaris hybrid? It has been reported that the 12-volt battery gets drained if the car isn't driven regularly.

Hi Nuran,

This is a challenge that affects a lot of modern cars, not just the Yaris hybrid and the issue here is not the battery itself, but the entire system that takes energy from it.

The Aygo X's electrical system is very very similar to that of the Yaris so, unless Toyota has made changes to reduce the chances of the 12-volt battery draining while the car is left idle for long periods, we'd have to assume that the Aygo X also needs to be regularly started up to avoid issues.
