Are OEM VW Batteries Better Than Aftermarket?

The battery on your VW is slowly going bad, and that's perfectly normal. Sooner rather than later you'll need to replace it. But what's the best option? Should you buy an aftermarket battery or stick with an OEM battery?

An aftermarket battery is always an option and can be cheaper to buy. However, that cheaper aftermarket battery could cost you more money in the long run. It may not be the right size or type of battery which could cause other issues. In addition to peace of mind, there are a number of benefits an OEM battery provides that you don't get with an aftermarket battery. We will cover those benefits in this article.

OEM Batteries Are the Right Size

If you buy an aftermarket battery, you may not get the right size or type of battery for your VW. Space under the hood has gotten tighter over the years, so OEMs have started using batteries designed for a specific space. This has lead to a greater variety of battery sizes on the market. When buying an aftermarket battery, it's possible you could get a battery that's close in size, but not quite exactly the right size. That can make installation difficult. Also, the battery terminals have to be on the correct side of the battery. The battery cables in modern cars aren't usually long enough to go to the other side of the battery. So even if you get the right size battery, if the terminals are opposite of what the car needs, the battery could be difficult or impossible to connect to your car. Worse still, the wrong size battery may make it difficult to secure the battery in its tray. This could cause the battery to come loose, get damaged, or cause damage to your car.

OEM Batteries Are the Right Type

There are also several different types of car batteries available on the market today including:

  • Lead acid batteries
  • Gel batteries
  • AGM (absorbent glass mat) batteries

AGM batteries produce slightly higher voltage than traditional batteries. Today's cars have a lot of electronic components and may require an AGM battery to function properly. Using a wet cell battery or gel battery when the owner's manual specifies an AGM battery could cause problems with your car's electronics and make it hard to diagnose issues. And if you get an AGM battery when the car's charging system was designed for a lead acid battery, the charging system will never fully charge the AGM battery. That will shorten the life of the AGM battery.

OEM Batteries Save You Money

If cost is an important factor in purchasing a battery for your VW, it's important to consider the total cost and not just what you pay for the battery. An aftermarket battery may not last as long as an OEM battery which means you will need to replace it more frequently. Additionally, the aftermarket battery may not perform as well as the OEM battery which is optimized for your VW's performance. Finally, you'll probably find the OEM battery is less expensive or comparably priced to a similar aftermarket battery.
