The question is often asked as to how long a battery will last in a vehicle like the Acura MDX. If you're reading this right now, there's a good chance you are asking that very question yourself. The answer is not as simple as posting a number like 4.2 years, because many factors play into the lifespan of a car battery, including how the vehicle is used, where the vehicle is used and how the vehicle is maintained.

Generally speaking, car batteries tend to last longer in temperate climates, that don't see extremely hot or extremely cold temperatures. Think something along the lines of a San Diego. On the other hand, batteries that do see extremely cold (International Falls, Minnesota) or extremely hot (Phoenix) temperatures may have significantly shorter lifespans.

Acura MDXs that see regular use for extended periods of time may also see longer life out of their batteries, for example, a commuter who adds 50 highway miles per day will likely see longer battery life, than an MDX that mostly sits and only gets taken out on short drives a few times a week. On average, some will suggest the average battery lifespan is about three to five years, but either end of the spectrum will have some outliers. We can offer some sound advice on how to make your battery last longer- keep your battery voltage properly-maintained whenever possible. 

We're so confident this will help improve the performance and extend the lifespan of your Acura's battery, that we will add one year of FREE replacement warranty coverage to your OPTIMA battery, if you buy an OPTIMA battery and OPTIMA Digital 1200 battery charger from us at the same time. So what is proper battery voltage for an Acura MDX battery? For most batteries, the answer is at least 12.6 volts. We recommend about 12.6-12.8 volts for our REDTOP batteries and about 13.0-13.2 volts for our YELLOWTOP batteries. 

Whenever any battery is discharged below 12.4 volts and is left sitting in that state, sulfation begins forming in the battery plates, which diminishes battery capacity and lifespan. The good news is, you don't need to be a mechanic or even mechanically-inclined to use an OPTIMA battery charger. We have battery pictures on the OPTIMA Digital 1200 charger and you just press the picture of the battery that matches the appearance of the battery in your MDX. Connecting the charger clamps is safe and easy as well, as the OPTIMA Digital 1200 features no spark technology and will automatically alert you, if the clamps are not connected correctly.

Once connected, just press the button and the OPTIMA Digital 1200 charger will do the rest, automatically charging and maintaining your battery, as needed. We recommend topping of your MDX's battery with an overnight charge about once a month, because batteries can become slowly discharged over time. So which battery is right for your Acura MDX? We have a "Find Your Battery" option at the top of every page on this site, but here's the short answer:

From 2001 to 2006, you can use a Group 35 OPTIMA REDTOP or YELLOWTOP.
From 2007 to 2013 the recommendation is just for the Group 35 OPTIMA REDTOP.
For 2014 & 2015, the OPTIMA Group 35 REDTOP or YELLOWTOP were both options again.

So which OPTIMA should you choose, if you can pick between the REDTOP or YELLOWTOP for your MDX? Either choice of an OPTIMA battery may last up to three times as long as the battery that came in your MDX from the factory. However, if your vehicle sees infrequent use or heavy accessory use (kids watching videos and/or plugging in devices in the parking lot at soccer practice, etc...) then the YELLOWTOP is the better option. If your MDX sees usage more closely resembling that daily highway commute, then the REDTOP should work just fine.

So what about the newer Acura MDXs built after 2015, like the one pictured above? Acura MDXs built in 2016 through at least the 2022 model year (as of this writing), will use the OPTIMA DH6 YELLOWTOP, which is significantly larger than the Group 35 batteries it replaces. In fact, it is 70% heavier than the Group 35 REDTOP. Why all that weight? It's not about cranking amps, but reserve capacity. The OPTIMA DH6 YELLOWTOP holds a lot more energy than the physically smaller Group 35 batteries, but that's what modern vehicles demand.

More electrical accessories, anti-theft systems and hotspots can all demand more electrical power from the battery, which is why all auto manufacturers are moving to physically larger batteries in newer vehicles. So remember, not only will these newer vehicles consume more energy, but you'll need to be more vigilant than ever before to maximize your Acura's battery performance and lifespan.
