94 1.4 fitting a bigger capacity battery - amphibianalf
hi all.........
i have another car thats been off of the road for a while .....
the battery went flat so i keep it on charge ...
would it be ok to use it in the clio to keep it conditioned, it's a 76ah from my frontera, i know it's alot bigger in power, would the altenator cope....
i would rotate the batteries to keep them both ok ........
CHEERZ........AL..........

I don't think using a larger battery would be problem, the alternator can't give more than the maximum output it was designed for.

i'm not sure how the charging system works exactly....i thought the larger battery would need more work to charge it ....so the alternator would have to work harder ..
if i understood what your saying.... the alternator cant be overloaded by the bigger battery...... will it then charge the battery to it's full capacity but just take longer.....
sorry for the questions i'm just trying to understand ........

It will just take longer to charge - the actual charging current is quite small compared to the rated output of the alternator.

Correct, as I say the battery charge current is regulated. The rated output of the alternator is how much current it can theoretically produce to power active circuits, i.e. ECU, ignition, light, HRW etc.
will it then charge the battery to it's full capacity but just take longer.....


Yes.
