No. A battery charger has to be specifically matched to the batteries to be charged.
As long as both batteries are the same voltage, you can jump start with the battery. If you want to charge the battery then use a battery charger.
older cars had a generator ,not an alternator, but you can always use a battery charger to charge a battery
You can use a universal charger. Usually they should charge any battery under 4.8v.
Impossible to say. You just use the battery and see if it will take and hold a charge.

The battery of the s80 including 2006 model year, is in the trunk. You can use any automatic 12v charger.
Fully charge the battery before its first use. The first 3 or 5 cycles try to fully drain and fully charge the battery.
A fully charged battery will read 12.6 volts. A battery reading 12.4 volts is 75% charged. 12.2 volts = 50% charge, 12.0 = 25% charge. You should use a battery charger to charge any battery reading less than 12.4 volts before installing it on the vehicle.
wht type battery do you use
Chargers don't care is the battery is used on a boat, a car, or whatever. What is important is that you match the voltage of the battery and the charger. Don't use a 12volt charger on a 24volt battery, etc.
Not necessarily. Any battery, even a good one, will slowly loose it's charge. Could be that something drained the battery. Clean the battery case and the posts. Slow charge the battery until it is full and then use it. You will soon know if it is good or not.
