I have a question pertaining to this. I had irresponsibly left my battery in my '97 Sea-Doo GTX in and attached over the winter in my garage (last time that'll happen). I hooked it up to a trickle charger and the charger started making this bizarre clicking noise that I had never heard before. I read the manual to troubleshoot. Turns out that the charger won't charge a battery if it has gotten below 4 volts. I don't know if that and the clicking noise are related though.
I don't have a volt meter (the next on my list of purchases), so I couldn't tell if has fallen below the 4 volt threshold. Anyways, I then tried using a regular full size battery charger on it, setting it to 6 amps/12 volts. It didn't register any voltage. I checked it a couple of hours later, no reading. I then allowed it to charge overnight. The next morning, nada. Am I doing something wrong that you guys can think of? Or, can a battery drain completely and when that happens is it no longer possible to charge it?
To add, I checked the fluid levels in the battery and they seemed fine.
Thanks for your help guys, though I didn't get any answers to my question in this thread:
