Is Eco really good for the battery?

While testing the new nikometer I noticed that if I drive in Eco, the regenerative current can go up to 13A.
I also read somewhere that the max charging current for Zebra battery with P type cells is 6A.
So - even though 6A was for real charging (long term), could driving in Eco mode have detrimental effect on the battery with short charging current of up to 13A?

I asked "Lynet", if charging with power charge might be damaging to the battery, and he said no. In pc mode you are up to 13a.

I am referring to battery current (@ battery voltage) and not the mains current (@230V).

Typically if you charge with 13A mains current you get 4A (or thereabouts) battery current.
