help with battery problem ^.^
*93 Civic Hatchback*
My battery light only comes on when I drive it hard, like reving it high every gear and shifting fast but after it will stay on for
5-10 minutes when I change back to normal driving condition. I can start my car no problem tho. Can someone tell me is it my battery or something els?

yeah, I'd say something is up with the alternator. First check the belt tension to make sure it's tight. than take a voltmeter and clip it to the battery terminals, start the engine and rev it a little bit and make sure the voltage stays around 14 volts.
If the voltage goes up high when you rev your engine the voltage regulator is probably shot, if it stays around 12v the alternator is probably shot.
Or go to a shop and get an AVR test done on your charging system, that'll tell you if it's the alternator or battery for sure
