Battery Exide or Deka

Exide are great batteries and are a tier 1 supplier with Yuasa, Bosch, Varta.

I currently run a Deka Intimidator in my rig and it's been problem free for 3 years now

IMHO, Exide works well till the last second and then dies off without any symptoms. Amaron shows alot of symptoms like extra cranking and lights dim for interior and dash lights when it's nearing its demise. Hence I moved to amaron. So should you.

After reading all replies and knowing the price of the dealers option, I took my chance with a Exide battery AGM 12-23, it was a perfect fit.

I don't think they are good at inverters, but I have used their battery for ups which lasted 4 years, now i am using the second one which completed one year

VW lists 3 batteries, 1 AGM (68 Ah, Varta) and 2 flooded (72 Ah, Varta and 59 Ah, Exide) that may be used.

Deka ETX15, Deka makes a great battery and they’re sold under a few manufacturers.

This one looks like it’s in very good shape, I’ve seen similar for sale for $200 to $300 but the couple I’ve seen at auction sold for $80 and $110 if my memory is correct. Both where in much worse shape than yours.

Just use a Deka ETX20L. I think they're 15 pounds or so and they're cheap and widely available. Mine seem to last about 2-3 years, although they usually die from me forgetting to turn the headlights off. I was able to recharge my last one using a wall charger and I squeezed another 6 months out of it before finally replacing it.
