6. Optima Batteries 8020-164 35 RedTop Starting Battery

Our rating: 8 / 10

Agm batteries are special in their own way. Rather than using a lead alloy to transfer the energy between the electrodes in the plates, they use a salt mix of an electrolyte – in the older days this was gel, now it’s more of an osmotic plastic.

The benefits of AGM batteries are that they are easy to manufacture, have a longer lifespan than their lead-acid counterparts, and have the ability to resist the pressure created by a build of hydrogen gas that limits the amount of cycles that lead acid batteries of the same size will take before they die. Rather than five years – like your old battery – you could expect an AGM battery to last for eight to ten years.

The 8020-164 RedTop is a pure AGM battery so you get the best storage capacity and the security of knowing that it will have the lowest discharge of any battery type in its class with an internal resistance of 800 milliohms per Amp. And that will mean that if you have a winch with 12v 80A lead acid batteries, installing the Optima will double the power of the circuit.

Frequently Asked Questions (FAQ)

Who makes the best AGM car battery?

When we review the best AGM batteries they're generally made by manufacturers who have gotten pretty good at the battery game. The best AGM car battery comes from brands like Optima, Schumacher, DieHard, and Odyssey.

You'll also want to look for a few important features when shopping for an AGM battery. First, look for the difference between top-post and side-post batteries. Most AGM batteries are top-post, but your battery tray might be in the way. Also, you'll want to check the warranty on your AGM battery and keep an eye out for sealed batteries versus replaceable caps.

Which brand of car battery is the best?

There are many different car battery brands, so getting started can be a bit overwhelming. In the end, price may be what you consider the most important factor, but we know many people who choose the wrong brand on purpose in order to save money. Unfortunately, there are many reports in forums and from friends who have had their battery die shortly after purchase. While more expensive, leading brands like Interstate, Deka, DieHard, and Odyssey tend to have a few more years of warranty on the store-brand batteries.

So which is the best car battery? In our opinion, the best car batteries are the ones that can start your car reliably when needed. If you are someone who plans to do some off-roading or there are bad winters in your area, you may want a more rugged battery that can handle vibrations and extreme temperatures.

Are AGM batteries good for cars?

Affordable, reliable and simple to use AGM batteries are great choice for car battery. AGM stands for Absorbed Glass Matt and uses synthetic fiber mats to hold electrolytes. Unlike flooded or valve-regulated lead acid (VRLA) batteries that have a liquid electrolyte, AGM batteries are virtually leak proof, which make them good for mounted applications. AGM batteries also have a solid state design, making one of the best for solar battery.

When looking for AGM car battery consider size, reserve capacity and number of cells. Also think about warranty; in general, the best AGM car battery should offer a warranty of at least two years and 6-10 years, and sometimes lifetime warranty. You should also ensure that the seller has a good return and exchange policy in the event of a malfunction. You should also consider weatherproof, vibration resistant and gel or glass mat.

Here are the top five AGM batteries.

Are AGM batteries worth the extra money?

Yes. AGM batteries in the same category are about 20% more expensive than a traditional lead-acid battery but they’re worth the cost. They’re more resistant to overcharging, discharging, and sulfating, which is a process where rust forms on the battery plates. Also, they’re sealed so they come with fewer leak risks. AGM batteries are made up of the same basic elements as a traditional lead-acid battery but in a different chemical arrangement.

The advantage of upgrading to an AGM battery from a traditional one is that while both can be deep cycled, AGM batteries don’t lose efficiency like traditional lead-acid batteries. AGM batteries can be more costly, but they can also save you money in the long run when it comes to replacement costs.
