kingsuv Posted May 15, 2008 Report Share Posted May 15, 2008 They don't last long if their under charged for realz. Most voltage now days(2000ish) keep them about 80% full they don't even get a chance. The smart guy who bench charges them first won't have as many problems.MLA I would think having a 14.4-14.8 charge and a 140 amp alt would keep it around a lot longer then it did. I only got 2 1/2 years out of a yellow top. then it died. It didn't get weak, just died. Quote Designing, building, and shipping boxes.

I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. Link to comment Share on other sites More sharing options...

Battery quality has steadily improved over the last 4 decades (personal observation), with a few stinkers in the line. Where you live (climactic effects) and how you drive play a part in battery life. So does charging curves & voltage. I have a Duralast (2 year warranty) POS battery in the shop pickup. It has a 1999 mfg date on the side of it, and still shows a 12.7v charge after an 8 hour rest. In the winter I see charging voltages as high as 15.9v, and when summer hits the charging voltage will drop all the way to 14.7 at times. Someday I am sure it will fail to crank the truck, but at 34f this winter it did just fine. If your system does not have short battery life with the replacment battery, then you probably just had a bad optima. 'Link Quote missinglinkaudio The United States Marine Corps.

It does make a good door stop though. We'll see now that it's back to stock again with just a Red Top and non of the 20 batteries it had to hold it up. The wife's F-150 got 7 years out of the stock battery. I traded it in with the stocker before it died. Both trucks had the same alt. Quote Designing, building, and shipping boxes.

I only got 2 1/2 years out of a yellow top. then it died. It didn't get weak, just died. Damn King. I had my Optimas since like 2000 or 2001 and when I pulled them out a few months back they only sat at 12.57 and 12.66 so I figured they did an ok job for me. I don't have anything bad to say about them....they just can't compete with newer batts that are on the market. not only should a battery be on a good charging system (especially if you have beat of course), but you should charge them with a good charger frequently.....its good for the batt, its good for the alt too Yeah Meade, I learned this the hard way. Dom school me on this one day while we were on the phone and I been good every since.

missinglink Posted May 15, 2008 Author Report Share Posted May 15, 2008 (edited) With the higher voltage for charging your batteries they no can reach a full level from your alternators charge. This voltage increase will help keep up the batteries a great deal. After all it is a part of electrical and we all now weird sh$% happens now and then. I like to charge mine after the long day of demo's just so I dont have to run the $3.60 a gallon rip off they call gas.
