Hi,
I plan to buy a Blue Smart IP22 charger for my two cars, but wonder which one is most suitable:
Car 1 has a 95Ah AGM lead acid battery
Varta recommends to charge these with I=0,25C to 0,35C, so between 24A and 33A
Car 2 has a 70Ah flooded (conventional) lead acid battery
Varta recommends to charge these with I=0,1C to 0,15C, so between 7A and 11A
The IP22 12/30 would charge the AGM battery fastest, but is it safe to charge the 70Ah battery in low/night 15A mode? That would equal 0,21C and exceed Varta's recommendation.
I'm a bit puzzled, because the C values in the Victron IP22 manual seem very high:
IP22 12/10A -> minimum battery size = 30Ah (0,33C)
IP22 12/20A -> minimum battery size = 40Ah (0,5C)
IP22 12/30A -> minimum battery size = 60Ah (0,5C)
Cheers,
Robin.
