That's the third new battery you've put in your Prelude this week, eh? We've got a tip for you: The problem may not be your battery. It could be your Honda alternator. The Honda alternator acts like a little AC generator under your hood, running all your fancy power accessories and charging your battery. If the Honda alternator output isn't up to spec, your battery never really gets charged from starting the car. That situation day in and day out can kill a battery fast, even though it's actually the fault of your Honda alternator. You can remove your Honda Accord alternator or Honda Civic alternator and take it to a shop for testing. Usually, that will determine if the Honda alternator isn't putting out the proper voltage or amperage, or if the diodes inside the Honda alternator are shot. In any case, a new Honda alternator is the way to go. We sell only premium Honda alternator assemblies, whether you select a new Honda alternator or a remanufactured Honda alternator. More importantly, we sell each Honda alternator at huge discounts over the dealership or local parts store. A Honda alternator isn't hard to remove and replace, but you still don't want to do it every week. That's why you should stick with a high-quality replacement Honda alternator like the ones we carry. Trust us, it's much nicer to be able to drive and enjoy your vehicle without having to worry about the Honda alternator--or the battery, for that matter!
