Need new start battery for GU - are the Optima yellow tops still worth it ?

**jff45** · 24th March 2021, 10:25 AM

I haven't kept up to date on what's good in the battery world so hoping for some advice on what to buy. The current AC Delco maintenance free did 4 years but I don't drive a lot these days so regularly have to charge it.

I'm looking at the Optima D31A but happy to consider any other suggestions..

I've got 2 d27's and happy with them, think there's plenty of happy optima customers out there the D31a is a beast

I rum 4 D31 M`s two in the car, two in the van, first lot lasted well over ten years of hard service before one started to fail so I renewed all four. Yes expensive but hey they never let me down and I do a lot of very remote work.
M is for marine better internal construction.
Best deal I got was from R and J batteries.

Have always run D27 Yellow top pairs in my GU’s and just installed two D31A beasts into the GQ ute.
Absolutely love them, my alternator recently took a dive on Thousand Dollar Track and the two Optimas paralleled hauled me out of the poop by themselves until the alternator came good again thankfully

I still run the Century 4x4 over lander N70ZZXHD as my crank battery. At least new you get 36 months warranty and if you got a SCA trade card, or club card, you can get it for under 240 AUD

So thats is a basis for comparison with the Optima range to think on.

I had the Century before the AC Delco. I switched to the maintenance free AC Delco because the Century often needed topping up.

I’m going with the Optima anyway even if I could buy 2 Century batteries for the price..

I’m 75 now so the Optima might hopefully be my last battery purchase

My remark was really a reflection on how long I hope the Optima will last, not really about my mortality

There’s also the question of how long one is allowed to drive..

Yes, I understood that John. Just thought I'd add the other perspective.......

Just after confirmation that the D31A does fit into the GU starter battery frame..
