Battery Bosch or Duralast

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 am using Bosch battery for my BMW, going through my 2nd, it lasts for 2 years+, less than 50% of the price of the dealership

I've also had great luck with AutoZone's Duralast Gold/Platinum batteries and they have better warranty than most others as well.

Also the original equipment Bosch battery that came in my wife's 2006 TDI Golf when we bought it in 2015. The good ones aren't available anymore by the time they wear out.

My last battery was a Duralast Gold and it lasted 7 years.

Picked up a Duralast Gold from Autozone back in July for my GLI. $155 after returning the OEM battery for the core refund.

I find that the Bosch batteries I regularly sell last 5-7 years or 5-7 months.

the IP64 battery cover can't close because the battery is too high, it should work no problem with any other 18V Bosch battery including the Procore 4.0Ah.

Good light though, it's really bright.

And heavy.

I've been seeing the same issue with batteries branded under Bosch and Champion. On several cars, I rarely had to replace batteries, now it seems like it is a 1-2 year thing on any battery. They are dying faster without ability to recharge. I just posted in the Scirocco forums that my 3 year warrantied Bosch battery is no longer holding a charge and its not even 11 months since I bought it. Glad to know that I'm not alone in seeing that engineered battery obsolescence seems to have arrived.

I've gone through two VW batteries in 32K miles under three years. They suck. Just replaced it with a Duralast Gold from Autozone which has a 3 year full replacement warranty and 5 year prorated.
