1. Optima Batteries 8002-002 34 – The Big Beast
Optima batteries have a very distinctive look. You’ve probably seen them on display at an auto parts store (if you go into those sorts of places) and wondered what makes it different from other batteries. This is a fair question when you consider the high price of these batteries, but these are some of the best AGM batteries around.One of the best things is that these batteries are made with a reserve cell that gives the user an extra 100 minutes of power. This is great for those times when your car breaks down on a long trip. At 800 CCA, this is the most powerful battery on our list.
- Highest CCA on our list
- Well-sealed
- Resistant to vibration
- May not fit in smaller cars
2. DieHard 38188 GP 34R Advanced Gold AGM Battery – Old Reliable
DieHard is known for producing long-lasting batteries that fit their brand name.This is the flagship of their lineup, and it has 775 cold cranking amps to its name. This is good enough for almost any vehicle.
This battery is made in a well-sealed container, but it is possible to add more acid if you choose to do so.
The main selling point of this model is its exceptionally long lifespan.
- Long life
- Well-sealed but not totally sealed
- 775 CCA
- Cannot be returned
- Quite expensive
3. Bosch S6590B S6 Flat Plate AGM Battery – Lives Long And Prospers
This one is a little smaller at 650 CCA, but it’s big enough to get the job done.This is a high-powered option for small vehicles, so that they won’t feel too left out when reading this article.
The main selling point of this battery is something called “Energy Life Technology.”
This is simply a design that gives slightly better longevity when compared with traditional batteries.
- Very thick and well-sealed
- Convenient carry handle
- Enhanced longevity
- Backed by a roadside assistance plan and free replacement for 4 years
- Unnecessary for very small cars in terms of power
- Very tall shape may not fit a lot of cars
4. Optima Batteries 8020-164 35 – The Little Beast
This is another red-top battery from Optima, and it looks a lot like the first one that we reviewed.However, this one is a little smaller, a little weaker, and a little cheaper. For those with smaller vehicles that require smaller batteries, this is a great option to get the performance of a racecar without burning out your electronics.
This battery packs 720 cold cranking amps and boasts a reserve cell that lasts for 90 minutes. Overall, an excellent and well-designed battery for those who can afford one.
- High CCA level
- 90-minute reserve cell
- Resists vibration
- Unaffected by bad weather
- No warranty
- Pretty expensive
5. Exide Edge FP-AGM24F Flat Plate AGM Battery – Dynamite In A Small Package
This is the smallest battery on our list, at 710 cold cranking amps, but it also has the biggest reserve cell of all these batteries.The reserve cell on this battery can go for 120 minutes before the battery finally dies.
This thing is dynamite in a small package. Even with that big reserve cell, this model manages to get a lot of power without a large size.
According to the company, this is due to a special graphite-based design that maximizes power output.
- Compact
- Huge reserve cell
- Improved electrical efficiency
- Very expensive
- Relatively low CCA
Choosing a Car Battery For Hot Weather – Buyer’s Guide
If you are concerned with these temperature issues, you should look for an AGM battery.
These batteries work on a completely different principle compared to standard car batteries. Instead of using a liquid suspension, AGM batteries use a mesh made of absorbent glass to soak up the electrolyte.
Although these batteries are still using similar electrolytes, this design eliminates a lot of their temperature-sensitive properties.
The benefits of an AGM battery include:
- Much longer battery life
- High level of cranking amps in a small size
- Spill-proof
- Increased safety factor
- More efficient when charging and discharging
When you look at a battery, you are basically looking at a chemical reaction in a box. Batteries are composed of both liquid and solid chemicals that react with one another in an energy-producing reaction. Electricity has a tendency to move from a positive-charged substance to a negatively-charged substance, and a battery is all about capturing the energy flow that results from all of these chemicals working together.
However, extreme temperatures of either sort will keep the chemicals inside the battery from reacting in the way that they normally would. In cold weather, the reaction is slowed. That’s why you have to let your car heat up for a few minutes in the winter. In hot weather, you get the opposite effect. The reactions that take place inside the battery produce a small amount of heat. When the hot weather is added into the mix, the reactions can proceed too quickly. Not only does this shorten your battery’s life and durability, but it also causes the liquid to evaporate more quickly.
Conclusion
As with any car-related purchase, your choice should mainly depend on the type of car that you own. We hope that we have given you a sufficient quantity of options so that you can find an AGM battery that fits your vehicle. With any one of these batteries, you can stop worrying about those weather-related car starting issues.
All of these batteries are well-sealed, made for safety, resistant to the weather, very powerful for their size, and made of robust materials. Any of them should serve you well.
