Audi Q5 Battery

More than two million Audi Q5s have hit the road since Audi started producing them in 2007 (although production really didn't ramp up until the 2008 model year). The first generation (2009-2017) were manufactured in five different factories around the world and the second generation Audi Q5s had seven different engine options, so it's easy to see why the battery fitment chart looks like a bit of an eye test. It's also easy to understand why selecting a replacement battery for an Audi Q5 can be a confusing process, especially if you are not familiar with your Q5's PR code.

So what on earth do all those numbers mean in the second column? The "54" signifies a battery that is vented to the outside atmosphere and pretty much all Audi Q5 batteries are. The "57" indicates Audi used various sizes in their production, which means they basically recommend measuring your current battery, to figure out what size you have.

If the battery's longest length is just under 11 inches, you probably have an H6 (sometimes referred to as a 48 in the third column). If your battery's longest length is just under 12.5 inches, you have an H7 (sometimes referred to as a 94R). Those are probably the two most-common sizes, although if your battery is smaller than the H6, you probably have an H5 (aka Group 47) and if it's larger than the H7, you probably have an H8 (aka Group 49), although if you see a 95R on your battery, you may have an H9, which is larger than the H8. If you're not quite confused yet, there's more!

The number 67 in the second column indicates your new battery needs to be registered with the vehicle's charging system and that is required of pretty much all Audi Q5s. Many scan tools can do this, but if you don't want to buy a scan tool, you'll have to take your Q5 to a mechanic or dealership to have them register the battery. 

The 69 in the second column indicates an AGM battery is required in your Q5. The number 70 in the second column indicates the Q5's PR code will define the battery your Audi needs and the number 73 indicates a lithium-ion battery.

Can You Simplify This For Me?

The OPTIMA batteries online fitment guide for most Audi Q5s will likely show either a DH6 or DH7 YELLOWTOP as replacement options, but we've come across other online fitment guides that show up to nine different options in three different sizes and two different technologies, so which one is it?

In terms of the two different technologies (flooded & AGM), we would recommend choosing an AGM battery. That's the only type of battery OPTIMA manufactures and our batteries will last up to three times as long as a flooded lead-acid battery, so we definitely believe they are worth the investment.

Additionally, if you have the option of either an H6 or H7, we'd suggest going with a DH7 YELLOWTOP, which is conservatively-rated at 880 cold cranking amps. It's unlikely you'll need anywhere near that amount of cranking amps to start any engine offered in a Q5, but the larger reserve capacity of the physically larger DH7 YELLOWTOP means when you use energy from your battery, it will be a shallower discharge cycle. Peukert's Law relating to lead-acid batteries (including AGM batteries), basically says that the more shallow the discharge cycle on the battery, the more cycles (and longer life) you will get from the battery.

To that end, we would also recommend periodically charging your battery with a quality battery maintenance device. Even connecting your battery on any daily-driven vehicle to a charger once a month will help keep the voltage properly-topped off and extend battery lifespan. OPTIMA offers both chargers and maintainers and we're so confident they will extend the lifespan of your OPTIMA battery, we'll add an additional year of free replacement warranty coverage to your OPTIMA battery, if you purchase an OPTIMA Digital 1200 battery charger from us at the same time as your OPTIMA battery purchase.
