Question:

Why Smart Chargers will not charge a dead battery?

Automotive battery charger that will not charge a fully discharged battery. It says in the manual to take the battery to an automotive center to test battery. It is a new battery, we just left a light on and totally discharged the battery. I thought that is why you buy a battery charger? This happen to me once before, but I was able to force the charger to charge

Answer:

Tell us about it? Freedom Battery? How long did you charge it at what Amperage? was the Battery Fully Disconnected from the car (Both Battery Cables Off?)? Must be fully disconnected, Cell(s) not bubbling (Dead Cell), Charge at 10 to 12Amps for 4 to 6 hours, Yes New Batteries can be Bad. After all the above doesn't take and have it Load Tested.
What kind of smart charger is it? Some of them have a supply mode and some you push and hold the charge button and it's like a manual override.
Disconnect the battery completely. examine acid point in each and each cellular, right up with distilled water if necessary. connect charger - valuable lead final. Wait till battery fluid is 'effervescent' in the previous disconnecting + lead first. do no longer smoke over a charging battery, the fumes are explosive! If the battery desires charging probability is it desires changing. they could be renewed each and every 2 or 3 years. short journeys on chilly, darkish days take lots out of a battery. Diesel engines choose extra of a fee to start up.
the charger is a piece of crap. the whole point of a charger is to charge a battery. if it wont charge it then the charger is junk, get a new one. i would just jump the car and let the altenator do its job.
