Do I need a new battery?

All of a sudden this morning truck is struggling to start. It’s either a looong crank or it starts and shuts down and finally catches.

 

That's what happened with mine and it was dead the next morning. I got six years out of the OEM battery so no complaints.

 

I’m gonna hook the ELM up later but I did alternator a couple years ago. But yeah I think this one has about 8 or more

 

You can do a quick test with a DVM to get a pretty good hint, or any parts house should load test it for you for free.

Personally I do my own test, then if I need a battery get an Interstate at Costco for ~$100, cash and carry + your core.

 

Oh cool I always forget about Costco and I have a membership haha

 

Which group size? I’m running lights and a winch

 

I just had advanced test it and it’s good so maybe there’s another issue might be related to the winch

 

have it tested at VATOZONE for free

 

One weird thing is when they put it on the tester it was double the cranking amps with nothing running so I pulled the connections and it was fine...

 

I did and it was double the cranking amps until I pulled the cables and then it was normal

 

did this only happen once? my truck will run weird on the first startup after disconnecting the battery. the computer is relearning everything. it holds rpms longer when the clutch is pressed too.

 

I have an auto and no it started doing this today the double cranking amps with everything connected is weird though

 

sooo?

 

if it has double cranking amps hooked up to the terminals but normal when disconnected, sounds like some wiring got crossed or something. but i have no idea lol

 

Ok went to Vato Zone this time now everything is fine she starts up fine alternator is fine battery is fine. I pulled the positive cable from the winch because that’s all I could think of so maybe it’s a grounding issue but of course I could sit here and we could all guess all day but I’ll go home later and do some tracing and figure it out I reckon thanks for everyone’s help

 

Awwww.....c'mon.

Guessing then debating will be lost with facts from diagnostics.

 

We can keep going, I think it’s related to my winch to be honest, I have lights and a winch and I should probably upgrade to a beefier battery or two batteries. Or maybe just keep the winch disconnected and only connect it when using it. I actually think I remember seeing some winch disconnect thing on TW at some point...

 

You have 8 years on your current battery? Damn I'd replace that for peace of mind if nothing else.

@Muddinfun thanks for the help again I owe you a beer one day if we ever meet as much as you help me (or a soda if you don't drink) but I agree probably need to bit the bullet and buy a nice deep cycle or something
