Lots of posts about the stock battery not lasting on the Mk5/6 threads.So I decided to go with a new technology: AGM (Absorbed Glass Matt) battery from AutoZone.Ībsorbed glass mat (AGM) battery designed to give you the ultimate combination of power, durability and flexibility. My stock battery died after 3 yrs 9 months. All things considered, what's not to like? Cost is around $110-$130 at the dealer and is one of the rare cases where dealer pricing is competitive. I've had nothing but exemplary performance and longevity from them. Without spending over $200 for super cutting edge technology, the OEM Varta is still the best option available. Calling Interstate, they did not have an Optima battery that met the specs required by our TDI's. We are an Optima WD where I work and use the Blue Tops exclusively as we are a boat mfg. Group 34, probably the most popular battery of all.Ī lot of people here have sought a 'better' battery for their TDI's, most turn to Interstate or Optima. We also use quite a large battery, bigger than the std. Extended cranking requires lots of reserve, way more than run of the mill gassers. long term amperage because of the high compression of our motors and cold weather does nothing but make that more important. The issue with our diesels is due both to the starter needing high. The use of AH by VW and other European mfg's is not readily available as a spec when walking into your local A/P store. It is somewhat confusing because CCA has become the standard measurement we go by here in the US and the simple buying logic is more is better. If you get a properly rated Ah, CCA's will always exceed the requirements of the car! battery size and type (poles, size, anchor mounting) AND all BEFORE YOU EVER HIT THE STARTER without ALLOWING the voltage to drop below 10.5 volts!ĬCA is simply a bogus sales tactic that tells you NOTHING about the capability of the battery to deliver AMPERAGE while SUSTAING VOLTAGE for extended periods OR short periods at HIGH LOAD.ĬCA = a hammer and the short duration of the initial whackĪh = a vice and sustained pressure equal to or exceeding the force of a hammer but for extended periods of time beyond what most battery's could ever hope to supply The first priority for ANY modern car is Ah rating FIRST which DIRECTLY corresponds to the ability of the battery to Supply a minimum voltage under load for an extended period.Powering 7 glow plugs (50+30amps), ECU, Immobilizer, radio, heated seats, lights, instrument cluster, ESP computer, ABS computer, CD changer, Fan for the climate control, 30-40 engine sensors and servos, tank fuel pump. VW states that 72Ah is the MINIMUM battery size due to CONSTANT draw of subsystems of the ECU, Immobilizer, radio, anit-theft, remote control radio, Instrument cluster and the car is just sitting in the off postion! Even with a properly rated battery, leaving a car undriven for more than 2 weeks will result in a dead battery due to the continious load on the battery by subsystems that are always "on" regardless of key position.ĬCA is absolutely useless for modern cars ESPECIALLY the TDI due to the extreme demand systems that activate BEFORE you turn the starter.
