Anyone want to talk me out of getting a new Optima ?
I have had a D34/78 Yellow Top Optima in my 2000 TJ for 8 years and have had absolutely no problems with it (making it the best, or at least longest lived battery I have ever had). However, it got badly discharged several times over the winter and it now doesn't appear to be holding a charge too well. So, I've decided to pick up a new battery when I am up in Salt Lake City on Monday.
I know quite a few folks have had issues with Optima's and don't like them, and yet, others swear by them (which I guess I have to put myself in the latter group). Anyway, anyone want to talk me out of getting another Yellow Top in favor of some other high-end battery? |

Personally, if I replace any automotive application battery it will be one or more of the Sears Platinum Die Hard versions. They are made by the same company as the Odyssey with a much larger range of applications and terminal configurations. Plus the warranty is outstanding if you should ever need it and even with Optima trying as hard as they can to be mainstream, I doubt you'll find one in most places before you find a Sears outlet.

Sears Platinum. It's a little spendy, $210 OTD. However, as Blaine meantioned, the warrenty is excellent, 4 years free replacement/next 4 years pro-rated. Its also a huge plus that Sears are just about everywhere.

BTW, are the Sears Platinum Die Hard batteries an AGM type battery like the Odyssey? Also, do you feel that they are as vibration resistant as Optima's? |

OK ... I just did a quick search and the Sears Platinum Die Hard is an AGM type battery.
A few other questions: 1) Are you guys specifically talking about the "P-1 Platinum Automotive Battery from DieHard"? 2) I am just going to plop this in the stock battery tray. Anyone know off hand what the group size is for a battery in a 2000 TJ? 3) It's my understanding that an AGM battery is more sensitive to charge rate and maximum charge voltage than a run-of-the-mill flooded lead-acid battery. Does anything need to be done to the alternator or charging circuit to prevent any issues in this regard? 4) Is the Sears Platinum Die Hard a good battery for both starting and winching? (This was in fact the reason I originally went with a Yellow Top instead of a Red Top Optima). Thanks, Don |

An AGM battery is a conventional lead-acid battery (just that its acid is in paste form that is soaked into glass matting) so it is charged and has the same charging characteristics as any other battery. You're probably thinking of gel cell batteries which are totally different, rarely used in cars, and do indeed require a different charging system due to their high internal resistance that means it has to be charged at a much lower rate.
And yes, the Diehard Platinum is entirely suitable for both starting and winching duties. |
