So what sets the three Optima batteries apart from other AGM batteries? Well, that has to do with the design. It doesn’t matter what color top Optima battery you have they are all made the same way. Inside the Optima batteries the plates are wrapped in coils.
These coils give more surface area and allow them to discharge better as well as recharge better. This advanced design is what gives them superior performance compared to other AGM batteries and why users love them.
If you won't have a better understanding of AGM battery, we will briefly cover what an AGM battery is. AGM stands for Absorb Glass Matt and means that the liquid that holds the charge in the battery is held in a glass matt.
These matts are between the plates in the battery and suspense the liquid between the plates. This has a lot of benefits, but is too much to go into detail here in this article. Knowing the basics thought of an AGM battery is important to help you find the best AGM Battery.
So, which one of these AGM batteries is the best? Well, the answer is one of the Optima ones depending on your need. If you just need a good starter battery for your car, then the red top will do the job great.
