Hello my 1992 prelude battry warning ligt stays on wat does this mean

Most cases, the alternator isn't charging the battery anymore. And the battery is draining to keep the car running.

That your alternator is not charging properly,check you fuses and relays first then have the car checked for the charge voltage.

Either your battery is bad or your alternator is not charging the battery correctly. Start the engine then remove the Negative battery terminal. If the vehicle dies you need to have the alternator replaced. If not then replace the battery.
