When your battery begins to fail, your engine might crank slowly and have a hard time starting up. When that happens, you can test it with a multimeter or go to an auto parts store for testing. Then, if it needs replacement, you just have to get the correct battery.
What’s the best battery for the Dodge Charger?
Whether your 2020 Dodge Charger has the 3.6L V6 or monster 6.2L Hemi V8, it needs an H7 absorbent glass mat (AGM) battery. You might also find this option listed under the 94R group size.
There’s a lot more for you to know if you want to get the best battery for your vehicle. Luckily, we’re about to cover all of that info in this informative guide. Follow along to get the facts you need in a jiffy.
Battery Group Sizes Explained
With the group size in hand, you can easily find a battery that starts up your vehicle with ease. This number also indicates which batteries will fit in the tray and allow the cables to hook up without a problem.
Across all trim levels, even the SRT Hellcat, the 2020 Charger uses the H7 group size. This size is also listed as a group 94R from some manufacturers.
Either way, the outer dimensions will be around:
- 12 inches long
- 7 inches wide
- 8 inches tall
You can expect to see a bare minimum of 800 cold cranking amps. The capacity should sit at around 80 amp hours, while reserve capacities in the 140-minute range are the norm.
Lead Acid, Lithium-Ion, or SLI? The Best Option For Your Next Dodge Charger Battery
With so many high-tech accessories on board, it’s no wonder that the 2020 Dodge Charger uses an absorbent glass mat battery. This style of battery is designed for high-performance applications and all the electrical demands of modern vehicles.
Expect it to produce enough power to start and run your vehicle on demand. And it won’t wear out fast, due to its ability to withstand rapid recharging cycles.
AGM batteries are also vibration resistant and sealed for a maintenance-free, spillproof experience. You don’t have to check for corrosion or low water levels while using this option.
If you need something a little more performance minded, you can upgrade to a Yellowtop battery from Optima. They are even better equipped to handle lots of horsepower and electrical accessories without a risk of prematurely failing.
OEM vs. Aftermarket: What’s the Difference?
Mopar produces the OEM batteries for the 2020 Dodge Charger. They require that you use their Mopar-branded batteries while your car is protected under its original warranty. By going the OEM route, you’re ensured a perfect fit, full functionality, and a generous warranty period.
You can choose between several OEM options, such as:
- 60 Series: 60-month warranty with 18-month full replacement
- 72 Series: 72-month warranty with full replacement for 18 months
- 80 Series: 84-month warranty with full replacement across the first 24 months
After that, they will prorate the value of the battery and issue a refund that covers the rest of the warranty period.
If you go with an aftermarket option instead, you’ll only get about 36 months of warranty coverage. And that typically does not cover full replacement. Instead, it’s prorated only to give you a discount on your purchase of a replacement battery.
The specs are typically the same between OEM and aftermarket options since that largely goes by group size. You can expect aftermarket batteries to start up and run your car just as well as OEM batteries.
Want to Go with an Aftermarket Battery? Here’s What to Do
OEM batteries from Dodge offer a lot of protection, but also have the price to match. If you’d rather save money up front, you can go with an aftermarket option without worry.
Many aftermarket batteries are available for the 2020 Dodge Charger from brands like:
- DieHard
- Duracell
- EverStart
- Duralast
- Optima
As you shop around, look beyond the price to confirm that the cold cranking amps are at around 800 or above. Also, check for a capacity of 80 amp hours and reserve capacity of 140 minutes and up.
Don’t forget to reflect on the reputation of the auto parts store or other retailer you choose. They will be the ones handling your warranty return, so pick one that won’t give you any problems. That way, you can get your prorated amount and apply it to your purchase of a different battery without any headaches.
