ok so i live on an island to i have to wait for a ferry everyday now coming home from work it was dusk and i had all my lights on (lowbeams, foglights oem bulbs) and the blower on medium , and the radio on got to the ferry put'er in park, shut off engine and forgot to turn my lights off, waited about 15 mins for the boat. Go to start the truck and get tick tick tick, got a boost and drove home.

Would having the lights radio, and blower on med for 15mins kill the battery?

I did a test on the alternator (with my amp meter) and its charging at 14.2v-14.6v (drops to 13.5v with every accessory on) at idle so i think its ok, now i did get a new battery i need a bigger one anyways

 

Take it from a battery expert. (I actually worked for exide battery for a year and a half). The stock battery is 650 cca. which means at a start at 32 degrees the battery is supposed to deliver 850 cranking amps too start the vehicle. My numbers could be off btw,( it's been awhile). Your peroblem is your battery had been discharged before you shut it off and ran your accessories. Their are a number of reasons for the dead battery, I think it is your battery deteriating to be honest the lead plates start to fall apart nand sink too the botttom of each cell. when the end is near for a battery enough of the cell plates fall off and cannot sustain the 2 volts for that cell. 6 cells equals 12 volts. (your amperage comes from more surface area in contact with the acid btw). When you have complete failure is when enough of the lead plate fall to the bottom and shorts out the entire cell. Ie; dead battery that will not recharge or retain a charge for very long.
sorry for the rant and length btw.

 

ya thats what i thought hope the battery was the problem i asked the guy at the counter for the biggest battery for my truck so hopefully it works alright
I also do work with batterys but its with solar energy and i know the battery's are a bit different
thanks

 

Oh one other thing all batteries are the same, their are only three or four battery mfg. 'ers left btw. globe union/sears, intestate. exide/ exide noreaster,sentinal. douglas/ deka, b&d. too name afew of the heavy hitters.
I like globe union personally , but they are all the same. cept the warranty btw.

 

I've got a battery brain on mine to make sure I never have a dead battery. Has saved my tail a few times since I've gotten it. I just got the regular bronze manual one though. It's pricey for what it is but not many other options around for the same product.

 

Time kills all batteries regardless of care or external forces. They haven't made the perfect battery yet. Battery tenders will keep a battery from it' own demise a little/ well a lot longer than without, But still they all breakdown eventually. Just like the human body actually.

 

I've recently started giving thought to my battery. It's not failed on me yet and the indicator on it is still green, but I've got a lot of extra draw on mine. Cab lights, extra lighted gauges, Hellas and of course the good old winch.

As soon as I can come up with a good mounting place, I'm going to a second battery. The stock location for the passenger side battery tray is out unless I completely redo my CAI setup.

That basically leaves me with the wasted space behind the front bumper. The battery will fit fine and cable runs will be short which is a major consideration due to the cost of 2 gauge wire. Getting a steel tray and either welding it in place or fabbing a bolt on is not an issue for me but there is NOT enough space to put it in and take it out from the top. This makes removale a PIA and I'd like to have the option of easy placement so I can use the battery while fishing or camping if the need arises.

This only other place to me is the option of utilizing the basically wasted space under my toolbox. Any side post battery will fit and installation would be a breeze as I could route the wires up thru a drain hole in the bed. Getting it out and putting it back would be a snap. The only major drawback to that location is that it will take a good bit of wire. The negative pole can be grounded to the frame under the bed, but that positive run to the other battery will be costly at about $3.50 a ft, I'm thinking I'm gonna have $75 in cable, not to mention about $25 in quick connects. Plus if I'm gonna go that far, I might as well make a secondary run to the rear bumper so I can have the option of using the winch from the Jeep on the rear of the truck if need be. I've got a receiver mount on order for it, so I can just slide it off the Jeep and on the truck in minutes. But now we are really talking $ for wire and more quick connects. UGH!!!

 

Run the other + cable to the large post on the starter. Close than the stock battery.

OP, your battery is weak and has little reserve left in it.

 

As i researched my own problem i noticed you had a green light battery? Yeah that light does one specific cell.btw. It doesn't give the whole battery the green light btw.
