Optima Batteries 8020-164

Optima Batteries 8020-164 35 RedTop Starting BatteryOptima batteries are known for their amazing quality and durability. The Optima batteries use a special spiral cell technology that lets them pack more power in a smaller-size battery.

In this article, we’ll discuss the features and applications of the Optima 8020-164 35 RedTop  Starting Battery.

The three main products of Optima are the RedTop, BlueTop and YellowTop out of which each has its own specialty.

The RedTop is known for its cranking power and is best suited to help you start your engine even in the worst of conditions.

Let us discuss some of the features the battery has to offer in detail.

Optima Batteries 8020-164 35 RedTop Features

Cold Cranking Amps

CCA or Cold Cranking Amps is the measure of the starting power of a battery. In car batteries, usually, the battery is designed to provide a high amount of electricity to kick start the engine. Once the engine is running, there is no necessity for the battery at all.

As such, the batteries are designed to have relatively lower capacity than deep cycle batteries. For example, you can use a RedTop to power electronics in your car but it would be highly inefficient.

The 8020-164 35 RedTop has a rating of 720 CCA which is amazing for a battery its size. A high CCA is especially recommended for people living in cold environments as in cold weather, it is harder to start the engine and the battery has to exert more pressure to get the job done.

Some old cars even have demanding engines that also require high-cranking power. It is always a good idea to find a battery with appropriate CCA ratings for your vehicle.

Reserve Capacity

Another property that defines the cranking power along with the CCA is the RC or reserve capacity.

In simple words, RC is the number of minutes you can crank your engine using your battery before the battery becomes unusable. But why would that matter?

Once the engine starts, the battery starts getting recharged. But until the engine starts, the battery must rely on stored energy to start the engine.

If you have a low RC and high CCA, no doubt the battery will provide a huge amount of electricity at once but maybe it won’t be able to keep it up for as long as it needs to start your engine. As a result, you’d be stranded with a dead battery in a car that won’t start.

RC plays an important role especially in bad weather when it becomes harder to start the engine.

The 8020-164 35 RedTop has an RC of 90 minutes which is some of the best options out there. It assures reliability and makes sure the battery doesn’t die out.

AGM Technology

The AGM technology used in Optima Batteries is one of the best out there. Optima batteries use a spiral cell technology that provides more area for reaction hence boosting performance.

AGM stands for Absorbent Glass Mat technology and is one of the most popular battery technologies in the market. AGM batteries do not need maintenance of any sort as they are completely sealed and contain no liquid inside.

This also allows you to mount the battery in any way possible without having to worry about losing capacity.

AGM batteries have been seen to have more battery life than traditional batteries. AGM batteries also provide great vibration resistance and are ideal for offroading. 

Well, apart from these amazing features. The Optima RedTop also has other great features such as a very long battery life with a warranty of 36 months when bought from an authorized dealer.

The battery is also affordable for most users and is a very good investment if it fits your requirements.

While the battery clearly has some amazing features but there are also some drawbacks that cannot be overlooked.

Optima Batteries 8020-164 35 RedTop Drawbacks

One of the most prominent batteries of the RedTop is its inability to provide deep cycle functions. This limits the series of applications a lot. However, the battery is solely meant to be used as a starting battery and it is pretty good in that field.

This battery will not be a good choice for you if you have a lot of accessories in your cars such as audio systems or extra lighting.

  • 720 CCA of cranking power.
  • 90 minutes of reserve capacity.
  • AGM technology.
  • Spill-proof and maintenance-free.
  • Excellent vibration resistance.
  • Less deep cycle functionality.
  • Can be incompatible with some vehicles.
