X sync is electronic flash. The flash fires in micro-seconds. FB? (can't remember) is for flash bulbs. Since they're an explosive metal being ignited by a battery, it takes an extra few mini-seconds for them to go off. They also have a longer 'on' time, so the shutter waits until the bulb is fully ignited before it fires.
Yes, you'll have a metering problem with the wrong battery.
Correct me if I'm wrong, David, but don't air cells start to deteriorate as soon as you open the package, giving them a short lifespan?
