installed optima yellow top deep cycle battery
hey guys, i recently finally invested in an optima yellow top deep cycle battery, previously had an autocraft gold....
although i gained the "deep cycling" ability, i did downgrade from 800CCA,1000CA to 750CCA,870CA, which hopefully isnt too bad
hes the new product in my truck. along with alot of wiring i cleaned up on the way
all my accessories are now ran through a nice split-loom tubing and all tie in to one of the "+" screw terminals.
i decided to remove my fuse box cover because i saw a few unknown wires hanging out...
now when i removed it , i saw this...
on the right side of the box you see a loose red wire with a ring terminal on the end, and a blue wire with a connector on the end. also at the top of the box you see another connector with nothing plugged into it... does anyone know what these are for??? should they be loose like that, or how the heck could i figure out what they go to?

Congrats on the yellow top, I am trying them this time around on my 2000 1500 5.3L (I did a dual yellow top install), and they seem to work good, mine say ?made in mexico" apparently they use to be made in the US and people do not like the ones from mexico as well. :-(.
No idea on the extra wires, your box looks almost identical to mine and I don't have any bare connections visible near my box.

Optima batteries have been made in Mexico for a long while and the US plant closed for good some time ago. See my response, here, for more details: http://www.gmtruckclub.com/forum/sho...#axzz265AdVxIY

Optima makes great batteries. The yellow top, however is not the optimal choice for automotive use. Deep cycle batteries are designed to be used to a deeply discharged state before being charged, while the starting battery is designed to give a heavier punch to start the vehicle and then be charged back up immediately. Deep cycle batteries are ideal for use in boats with trolling motors, campers, UPSs, and other machinery that doesn't have the ability to charge "on the fly"
With a deep cycle battery, you lose cranking time in the event your vehicle doesn't start up right away. You also will experience a shorter useful life from a deep cycle because it is not designed to be charged constantly. The optimal choice for vehicle applications would be the Optima Red Top... For future reference."It went together didn't it? Well then there has to be a way to take it apart!" - Me.

Plenty of people do things that "work", even if it is not the right way to do something. there is a lot more to understand about batteries than just the voltage. I have 6 deep deep cycle batteries in my home office that power the UPS units. Each of them cost about $450.00. The charging system on those batteries cost over $1000.00. It is the difference between the batteries lasting a year and the batteries lasting 8 to 10 years with maximum power availability across the life of the batteries. You would never think that there is so much to know about batteries, but there are books of information.
If it were me, I would take the yellow top back and see if they will exchange it. More often than not, those will not hold a full charge after 9 months to a year after using them in an automotive environment. The worst they can say is "no".

you would say say to opt for the red top or are you hinting at a whole other type of battery,
i guess these are the inputs i get from my fellow gmtc mates, which i shouldve gotten BEFORE i got this battery lol

The last time I looked at the price of optima batteries, they were almost twice the price of a comparable Interstate.
The optima is a good battery but perhaps over-hyped just a tad. I have had interstate batteries that lasted 8 years. Never had a problem with them.
