[DML] New battery - different capacity?

["Stian Birkeland" <dmc_norway@xxxx>]

Hello list,

Thinking about getting a new battery I discovered that it is hard to find a 
12 V Battery that has the same capacity as the original battery.

The original battery (as stated in the Owner's Manual) has the capacity of 
75 Amp/hour. At least where I live, the "usual" batteries for sale are 
either 60 Amp/hour or 90 Amp/hour.

Is there any chance of doing something wrong to the car's electric system by 
choosing the 90 Amp/hour battery (or the 60Amp/hour battery?) The 90 
Amp/hour has at least the same amperage as the MOTOROLA alternator...

I've also heard that the earlier Ducellier alternator on the first few 
DeLoreans was rated at 75 Amp/hour. Could this be why the 81 Owner's Manual 
also have this capacity of 75 Amp/hour on the battery?

DMC Joe?
