RobRainford New Member Jan 8, 2013 #1 Need a new battery in my D1 300tdi. Is there a benefit to getting a high Ah battery? Even though the alternator is standard 70, does this mean it will only ever charge to alternator capacity and not battery capacity?

R ricc Well-Known Member Jan 8, 2013 #2 the alternator rating is its charge rate.... the battery rating is its discharge rate..... rule of thumb, fit the highest rate battery that will fit in the space.
