Replace small 12v battery to regular one.

Is it possible to replace the nissan leaf original small 12v battery with a bigger capacity one from the petrol or diesel car ?
or the car will somehow struggle with the regular car battery ?

It will work just fine, I ended up with the OEM sized 51R Optima for a replacement but if I were going with a regular lead acid I'd have picked the largest one that would have fit under the hood and between the hold-downs.
Others have gone with a much smaller battery and they seem to work OK too, just not as much as reserve capacity if you accidentally leave something on or park the car for an extended period of time.

Bigger battery doesn't fix a thing.
Just replace it with cheap appropriate battery.
The cheaper the battery, the better :)
