Although I am new to this company I did a lot of research on these batteries and was very impressed. Once I got it installed I noticed a huge difference in my peddle and in my gas millage. I went from pushing 15/16mpg to now pushing 19mpg in town with a Jeep JK! All around awesome product and will definitely buy again.

Best Battery Made
This is my fifth yellow top I've bought. Ive used them in my boat my Chevy truck and now in my wife's car. The yellow tops in the truck and boat lasted years until I sold them. In fact they lasted twice the original battery's life or more. Yellow tops are well worth the price in service free life time double or more your origional battery.

9-Years and Still Going W/Yellow Top...
I Bought a Optima Yellow Top "Deep Cycle" Battery for My 99" Chevy Silverado Back on Feb. 9th of 2007"......Just Over 9-YEARS Ago.....and Its Still Going, This Has Been the Longest Lasting Battery I've Every Had in Any Vehicle I've Every Owned!!!.....
I've Been Very Impressed with How Long This Battery has Lasted, My Silverado is My DD.....and its the Only Vehicle I Drive......
Over the 9-Years Its More Than Payed for Itself, and IF and WHEN this One Goes Out, I Will Be Buying Another....Optima Yellow Top Battery for My Truck.....

strong starting battery. even on the coldest days it was the only one in the driveway that would start my trucks. I live in buffalo and it was a long cold winter, the battery never failed me.

Only Batery I will ever buy again.
I put one in my 78 Bronco Trail Rig/Daily Driver in 1998 it survived Alternator failure twice(One of those times I drove it 40 miles a day for two days before I knew the Alternator had failed), being hooked up backwards during a jump start, being drained from sitting undriven for up to a month at a time on 10 different occasions (always came back 100% on an overnight charge), I run a Warn XP9.5 Winch and a pair of 130W KC Offroad Lights with NO problem, and it lasted for 8 years with never a worry!!!!!! Simply the Best and Only Battery you you should ever buy!!!
What is the difference between the D31A and the D31T
Dan from on
The D31A has the SAE Post and the D31T has 3/8 Stainless Steel Stud. All other specs are identical. Thank you.
Hey! so I went ahead and ordered this battery with a M.O.R.E. Offroad dual battery mount that claims it will hold 2 of these, or 1 of these and the factory battery. This product (Optima Battery) says the wiring is not included...What all do I need to put the charging system and the alternator onto the Optima Yellowtop? I will run the factory battery with the Optima for my light bars and stuff...but I eventually would like to run 2 Optima Yellowtops! so what do i need (parts wise) to make that connection happen?

Most of the guys buy short positive and negative battery cables to connect the two.
Take the small end of the cable and hook to the original battery cable clamp bolt positive to positive and neg. to neg.

What are the dimensions of this battery...will it fit the battery tray of a 2014 JK Rubicon?
