Battery AC DELCO or OEM Volkswagen

i had my left side battery replaced about a year ago and i watched the shop (not a dealer) do it. the starter battery was not disconnected, the hardest part seemed to be lifting the battery out (fits tightley in there and isn't feather light).

get an acdelco group 47 battery fits perfect is the identical size as oem and is probably wayy cheaper than an oem, i paid 85 idk how much oem ones are

Jack on my visit the battery was also replaced. Part# 000-915-105-CE. They also replaced two modules that were causing a drain on the battery.

The VW service called yesterday (I took my car in that morning) and stated the battery (driver side) was bad, and was replaced ($347, if not in warranty). Other battery OK.
