Miller says a new two-ton, R-410A system costs $3,500 to $4,500; whereas replacing just the exterior portion of a R-22 system with a dry charge costs around $2,500, plus the cost of the refrigerant. Miller says he currently charges $50 for the first pound and $30 for each additional pound of coolant.
3) Charge the battery for 4 to 24 hours (depending on the size of the battery, bigger batteries with a larger capacity, e.g. Y50-N18L-A2 or YB16Al-A2, will take much longer to charge than smaller batteries e.g. YB4L-B or YB2.5L-C) with a Motorcycle Battery Charger. 4) After charging, disconnect the battery from the charger and leave to settle for 1 hour. 5) Re check the battery acid level (make sure it is up to the upper level mark) and top up the acid levels if required.
A: Charging time depends on the battery and the charger. For a battery being charged by the car's alternator it can take an hour of driving to get it fully charged. Car batteries range from 40AH to 110AH, and alternators range from 45 amps to 200 amps. If you are using a battery charger, a 10 amp charger will take 4 to 11 hours to fully charge the battery, a 2 amp charger will take 2-4 days. Of course you don't have to get the battery to full charge to get it to start the car.
