Re: 24 hr trickle charged battery...still dead
You know,
I bought a battery for my dodge dakota last summer. Brand new Duralast battery; real nice and strong. Damnedest thing is i havn't driven the truck in months, it sat all winter long, and I went out to start it one day and the battery was completely dead! It only sat all winter long (it was only like 6 or 7 months!)
When a battery is discharged the sulfuric acid id turned into good old fashioned water (H2O). when a battery that is discharged (and full of water) sits outside all winter it can freeze (will freeze) and when that happens the casing and plates can be damaged.
So, first off, 2A trickle is a SLLLLOOOWWWWW rate. It doesn't surprise me at all you had to charge it for a weekend to get it to do much of anything. It took my battery 16 hours to charge at a 10A rate.
Second off, i doubt there is any magic reason the battery died. The computer in the truck draws milliamps of current and after a long time of sitting it will draw the battery dead. It's part of life. If you are concerned about parasitic draw, use a test light or meter and find out of it is there or not. easy.
You're catching a bit of flak on this thread mainly because you are jumping to a conclusion without supporting evidence. Just do your tests and if the evidence shows you there is a problem you're good to go.
I think you should give that batt a good charge and then take it to autozone or other type of place and have em do a load test (as suggested previously.) That will give you an answer about the condition of the battery. If it is a serviceable battery you could check the electrolyte with a battery hydrometer too.
Good luck and keep us posted on your findings!!
Cheerz,
Wily
