I would say yes and no. No: If there is a little bit of corrosion on the terminals it is still battery acid and should conduct electricity. Yes: If enough battery acid has drained out where your battery cannot store enough energy.

First step to do is clean off your terminals with a bettery brush. Next, pop the fill cover off (if it has one) and check the fluid level. If it is low, you can substitute water (I have only used distilled) for battery acid and fill it up. Charge the battery (on a charger or your car). Bring the battery or the car over to checker and have them test it for you. They will tell you if the battery is in good condition. If it is fine and you still have problems, check you alternator fuse and your alternator.
Good luck.
