What is this clicking sound while trying to charge the battery in my Chrysler Town & Country?

sounds like a really dead battery!sounds like so dead its clicking the breaker in the charger ,cutting current and diming lights ,unhook one bat. terminal and charge ,something in van is drawing as fast as you charge,remember also + to + on connections

The clicking sound is coming from the fuse panel next to the battery, not the charger itself. Thanks for your suggestions. I'll remove the battery and take it to the auto parts store. I'll let you know how it turns out.

I took the battery to AutoZone, but they said they'd have to try to charge the battery before running any test on it, which would take about 45 minutes to an hour (they were closing in 15 minutes). So I brought it back home and connected it to the charger directly. I had previously only tried to charge it while installed in the van. This time, the battery took a charge. I put it back in the van and it started right up. So now the question is, why wouldn't it take a charge while hooked up to the van?

I suspect the battery is over 3 yrs old and will slowly lose its charge. If its 3yrs +.....replace it

why no charge in van.the van was wanting all the current for something,lights on or a short somewhere or alarm trying to go .a full charge and your good for awile, till you fix the killer drain,if you could get the button that triggers the door and disable it

My Nissan Maxima has anti theft that won’t let my car start I put battery charge on my car still won’t start &clicking from fuse box

I have the same thing on my Acura.

have 2008 f150. found that the tripping solenoid would kick off my charger. disconnected battery from the truck, charged then re applied. solenoid rest, starts fine.
