Battery Varta or Duralast

Outback has a Duralast Gold. If it helps, we’ve had some harsh -30°f days the last few years since I upgraded my battery. No issues what so ever on it.

I've put my trust in Varta. Previously had Bosch. I think you can put your trust in pretty much any brand if its covered by a 2-year warranty.

We needed to replace the original German Varta battery in our '14 A4 (date code Jun '13) after the first polar vortex in early '19. OE list was $227 (non AGM), discounted to about $195 at the local Audi parts counter. Advance Auto had an equivalent H9 for about $170, but the local store only had one with a late '16 date code (and proper BEM sticker). So they sold it to me as a \"used battery\" (after running their condition test and passing) to me for $45 + tax. Two years later, so far, so good.

I’ve had two duralast batteries in my 02 24v and they’re so old I honestly can’t remember when I put them in. But I’d say they’re about 6-7 years old, probably more. When those batteries finally give up I’ll definitely be getting new duralast batteries.

I recently got a Duralast Platinum battery and it has proven to be very good so far

The battery you want is an AUX18L 20ah battery. I used [This battery](https://www.autozone.com/miscellaneous-non-automotive/power-sport-battery/duralast-gold-etx18l-group-btx24hl-agm-ready-to-ride-power-sport-battery-340-cca/350084_0_0?spps.s=4782) myself a month or so ago, it is an ETX18L and it has been working fine.

I took the hit and got a Varta, been perfect since! It’s a second car that is often left for 3 weeks or more and I get a perfect start every time with the Varta battery.

I just replaced my OEM H5/LN2 group 47-sized battery with a Duralast Platinum H5-AGM Group Size H5/LN2 680CCA battery. After having my mechanic change the settings in the ECU from EFB to Fleece for battery technology, 60Ah for rated capacity and set the date of install for the last 8 digits of the serial number, all seems to be fine. It fits the OEM position and cover perfectly.

The older VARTA battery could only hold a charge for 15 - 30 minutes at the end. It has been in use since January 2020 and was out of use for 8 months in 2022.

ZeniPower battery could still hold a charge for a long time. Estimating 5-7 hours.

we see many 2 year old Duralast batteries that have failed.
