Optima Yellow Top Battery

[Sal-XK]

I'm Running Dual Optimas in Mine. A red for the main starter, and a yellow for the main Aux battery via a Redarc Controller. (Ive got another set of AGM's in the rear as well via another controller but these only run the fridge and aux lights etc). Mine are also triggered to automatically join when winching. Ive actually had to use these for around 3 hours on and off without the motor running (radiator chockers with mud and didnt want to overheatit) and still going strong. Hence why i use optimas

Made up a custom alloy tray to house the 2 optimas, relocated the fuse boxes etc.



Rear Drawers with twin 55Ah AGM in the rear for the fridge and aux lights, inverter etc.

That's a nice setup I like the dual optima batteries. I never though about relocating the fuse box I put mine on the other side of the bay but I can see plenty of benefits to having them side by side I'll have to take a look and rethink my setup now.

Well, after 101,000 miles it looks like I need to replace my original battery in my XK. I have a winch which I rarely use. The rest of my use is whatever they put on the 07 Limited, Hemi,sunroof, NAV, stereo, rear DVD etc.

I assume for now it is the battery. Yesterday morning I tried to unlock the doors with the key fob and noticed they didn't work and it wouldn't start until I put the charger on for a few minutes. Drove it yesterday with stops and starts no problem but dead again this morning.

I don't want to replace the battery and find out there was an electrical drain somewhere.

Anyway, everybody still happy with Optima Yellow Tops? Any other suggestions on battery choice or how to verify it isn't a discharge drain?

Go get your battery tested, they will tell you if it is still healthy my man. Then you will know there is a drain somewhere.

101k on a battery is pretty darn good, so me thinks its dead or dying. I have No experience with any optima, however.

Thanks, BonesWK. I'm charging it now. I'll stop by an auto parts store and get it tested.

You recommend the red over the yellow?
