How would you save a sulfated battery?
What will be an ideal response?
A sulfated battery can sometimes be saved. Connect a headlight bulb between the positive and negative posts and allow the bulb to totally drain the battery. Then recharge it slowly. Repeating the cycle of charging and discharging the battery will sometimes knock enough of the sulfation off the plates so that the battery can charge. If after two cycles the battery still will not accept a charge, replace it.

Microsurfacing is part of a pavement restoration and maintenance program that seals the surface of a street that has minor cracking to prevent water from penetrating into the base material. The annual cost of the equipment (truck, tank, valves, etc.) is $109,000 per year and the material cost is $2.75 per square yard. Alternatively, regular street resurfacing requires equipment that has a first cost of $225,000 with a 15-year life and no salvage value. The variable cost for regular resurfacing is $13 per square yard. At an interest rate of 8% per year, how many square yards per year must be resurfaced for the two methods to break even?
