Battery OEM Chevrolet or Duralast
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 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.
I've also had great luck with AutoZone's Duralast Gold/Platinum batteries and they have better warranty than most others as well.
My last battery was a Duralast Gold and it lasted 7 years.
We've been driving two EVs, a 2012 Leaf since Dec2011 and a 2017 Bolt since Sept 2017.
In the Bolt we lose about 40% range at -20 and lower. Bu the range is so good to begin with its not an issue.
Picked up a Duralast Gold from Autozone back in July for my GLI. $155 after returning the OEM battery for the core refund.
I had my battery moment on my 2011 Outback, I bought a Duralast Gold 640 CCA and it's been working fine ever since.
My 2.8-year old mk6 GTI OEM battery started to show signs of aging about a month ago. It took longer to start when the car is cold and finally it failed to start yesterday. I called VW roadside assistance, got a jump start and went to Autozone, bought a Duralast Platinum AGM battery with size H6/48 . More to follow after the pics.
I had the misfortune of having a dead battery today... I've had the Duralast battery in my car for less than a year... I opted for the $70 Duralast - it sucks... Piece of shiznit.
duralast has giving me nothing but probs.
