Description

What makes the Goodyear Platinum AGM Car Battery better than a standard flooded battery? Unlike flooded batteries that rely on free-flowing acid, Goodyear Platinum AGM Car Batteries use sealed Absorbed Glass Mat technology to lock in the electrolyte. That means no spills, no leaks, and no maintenance necessary. Are Goodyear Platinum AGM Car Batteries safer than flooded batteries? Yes, Goodyear Platinum AGM Car Batteries are safer by design. The sealed and spill-proof construction prevent leaks and reduce the risk of corrosion during installation, unlike flooded batteries that can vent or spill when tipped or overcharged. Do Goodyear Platinum AGM Car Batteries require maintenance to prolong their life? While there's no need to add water or check electrolyte levels, an occasional check is always beneficial. Keeping the terminals clean will prevent corrosion and maintaining a full charge will help prevent sulfation to help the battery’s lifespan. When you choose Goodyear Batteries, it's not just another battery, it's your investment in a product backed by quality. Whether you’re navigating city streets or conquering rugged backroads, our batteries deliver unwavering power to keep you moving. When you power up with Goodyear Batteries, you’re choosing a legacy that drives every product we create. Innovation for today. Power for every mile ahead.

  • Upgrading to AGM Battery Technology is worth it!
Edition: Group Size 35
This Goodyear branded AGM battery was well packaged and arrived in perfect condition. The battery is true to the group size and is a perfect fit; and it's compatible with the electrical specifications of the OEM factory-installed battery. This battery, however, is superior to the OEM as AGM (Absorbent Glass Mat) technology offers longer life, is completely maintenance free, and provides higher and more consistent voltage levels. AGM batteries are also safer as they are completely sealed and leak-proof. It’s important to note that the improved voltage performance of AGM batteries helps with the proper functioning of all systems in your car. For example, I upgraded my vehicle head lamps from halogen bulbs to CAN bus compatible, error-free, LED bulbs but did not experience the higher light output nor the flicker-free performance I was expecting. Upon upgrading from the OEM flooded lead-acid battery to the AGM battery, the LED head lamps are now noticeably brighter and they no longer flicker at idle. Do yourself a favor and upgrade to AGM technology, you won’t regret it! ... show more

  • This is the correct battery for your 2020 Jeep Wrangler
Edition: AUX12
If your battery dies in your jeep, after sitting a few days, it’s your auxiliary battery, which is underneath your fuse box that is dead. Mine had 8 volts on it. When the Jeep is sitting the auxiliary battery feeds the computer if that auxiliary battery is low voltage or dead. It’s going to pull from your main battery. On my 2020 Wrangler, I was able to just go underneath the car on my back move the fender wall flap over remove the 3/10 mm screws and drop the battery down. Do yourself a favor and take pictures so when you’re putting it back up. It takes a little figuring and fiddling around to get it to seat right but then you’re able to put the box cover back on it. Push it up and throw in your three screws. When I connected that auxiliary battery, I got a little spark, knowing the main battery was out out of the jeep I knew that was my problem of my main battery dying when the Jeep sat for a couple days because that auxiliary battery was now drawing from the computer and that’s what its job is. ... show more

Was the wrong size for my vehicle really frustrated that this is what Amazon recommended for my 2000 Lincoln and instead gave me a size for a bike

  • Great price, no issues so far.
This battery was placed in a 2019 VW Jetta R-line and, so far, has performed as expected, and the price cannot be beat locally, this is almost half the price. Originally, I purchased a standard flooded battery from O'Reilly's that cost more than this AGM version, and it failed miserably after a few months. We drive short distances with lots of starting and stopping, and a standard flooded battery can't reach a proper charge without some amount of long distance and/or highway driving. The AGM can charge at a higher rate, and is designed for cars with auto stop (i.e. shuts off at traffic lights) Note: If swapping batteries with different technologies (EFB, AGM, Flooded), you will need to register/adapt the battery using an ODB scan tool, otherwise the charging characteristics may over/under charge the battery. We've only had the battery installed for a few weeks, if anything changes, I'll edit the review as needed. But so far so good ... show more

  • Replace your Dead Mopar Auxillary Battery with This Quality Replacement
Edition: AUX12
I used this battery to replace the auxiliary battery in my Pacifica. The Mopar batteries just do not last. Hopefully this one will do better. unfortunately only time will tell. Fit was exact except for the battery connection posts which had to be unscrewed from the dead battery. This is easily achieved with a mini socket. The Goodyear comes with holes in the battery terminals that the posts are simply screwed into exactly the same as the Mopar original battery. Delivery from Amazon was faster than going to the repair shop and even the store, which did not have an equivalent battery. Ordered in the evening arrived 6 am from Amazon, installed by 7 am. Amazon is amazing! ... show more

  • It's a battery
It's a battery. It's the right size for my car. It starts my car. It was less expensive than the batteries at the local auto parts store, and has just as much power. What's not to like?
