My Explorer was sitting for a month and the battery, a relatively new DieHard, naturally died. When I hooked it up to my trusty 4A charger, the gauge shot up all the way to 6A, stayed there for a minute or so then click. It shuts down. Do I need a bigger charger or something in the battery has shorted out? I have it on trickle charger now and that's working but its real slow.
A trickle charger is designed to maintain a charged battery. It might not get the battery back to 14V If it does, it will take many days. Do you have a multi-meter to check for volts?
I know. My thinking is to bring up the charge a little then go with the big charger. It's drawing too much current at start up. Temp sensor must be kicking in because it takes a while.
Charge it with the trickle-charge for 6 to 8 hours.....then set it onto the regular-charger at 2 or so amps overnight, it will come up.
It sounds like the voltage of your battery dropped a lot. This resulted in a large difference between the battery being charged and the device charging the battery.......this large voltage-difference is what popped
overcurrent-protection on your charger.
I doubt it is a shorted-cell, definitely not sulfation, doubtful it is some sort of internal damage.
Put a car light bulb in series with your charger to limit the current, might be enough to get the battery charged enough to then remove the bulb and finish the job.
First, sounds to me like you hooked the charger up backwards..
Second, a month and the battery is dead - as in no nothin, or it just wouldn't turn it over?
DieHards are around if you still have a Sears store nearby. Ours closed a couple of years ago. As in connecting the charger backward, no, I did not. My plan C is to give it a jump with my portable jumper, which of course needs charging too!

Did you read the no-load voltage on your battery......if so, what is it?
