No, for use when driving as well. They are called Battery Thermal

battery, not cool it.


Cold like Siberia/USA, not the UK.

Depends where and when in the UK.

I see you have not read the link *you* posted earlier then...

Any time you charge or draw current from the battery and its outside a
defined temperature range you will get accelerated battery ageing and
hence loss of capacity and possibly reduced peek current delivery.

Cheers,

I read my own car instruction book. The temperatures mentioned are way outside our UK climate

Would that be operating limits for the car or for the battery?
What model and year is it so we can all look at what it says?

The battery is the problem.

Do you air con the garage as if the car is above 25C it damages the battery?
Of course its never above 25C in the UK.
