Thread: Who has fitted a battery behind the second row of seats in a D3

Any hope for the battery?

Unfortunately no.

Once a battery starts behaving like that, it's stuffed.

This would also most likely be the reason your Optima was not holding it's voltage, but it is probably good.

Thanks. I thought so.
