Who Is This Product For?

The RedTop battery is specifically designed for all types of vehicles and weather conditions with its SpiralCell Technology. 

Suppose you are living in a place where the weather conditions are bad. In that case, the Optima RedTop is also suitable for you as the RedTop is engineered to provide high power cranking capability even in adverse weather situations. With its leak-proof, high power, and starting capabilities, this battery is ideal for heavy usage by hot rods and off-roaders. 

The innovative SpiralCell design delivers a powerful and clean power source, assuring your, your family’s, and the environment’s safety. In addition, the increased reserve capacity provides a longer shelf-life, allowing you to have power when and where you need it.

It is also appropriate for agricultural machinery, frequently utilized at certain times. For example, even if the battery in a tractor or harvester is left in the winter, the Red Top will start the equipment easily in the spring. 

Optima’s AGM Spiralcell battery technology is the secret to its exceptional starting power. This technique is built on several individual spiral-wound cells made of two pure lead plates covered in a perfect lead oxide coating.

Features of Optima 8020-164 35 Redtop Starting Battery

SpiralCell Technology

For almost 40 years, Optima batteries have been the best power source for automobiles, trucks, SUVs, boats, and commercial vehicles. An Optima battery is easily distinguished from any other automobile battery. 

Optima is the only battery manufacturer to use SpiralCell Technology, which gives each battery a distinct shape and form known as the brand’s trademark Six-Pack design. Every OPTIMA battery has a series of unique spiral-wound cells of two pure (99.99%) lead plates covered in a perfect lead oxide coating. One covered plate is positively charged, while the other is negatively charged.

The spiral winding continuous lead plate production technique is significantly more precise and costly than constructing typical flat plate AGM batteries. Therefore, custom automated cell-winding devices are required to maintain the precise tolerances necessary for quality and performance. Critical tolerances, temperatures, humidity, and automated operations are continually maintained and monitored.

Easy to Install

Optima 8020-164 35 RedTop Starting Battery is easy to install if you follow the instructions carefully. Your Optima may or may not include an adapter kit, but if it is included you should remove them before installing the battery. Besides, it is very safe to install the product following these steps:

  1. Lift the hood and, if you have one, put on your fender cover. Please remove the battery from the package and store it somewhere secure.
  2. Remove the new battery cap. Keep it; you will need it afterward.
  3. When you remove the old battery, you will have complete access to the battery tray. Test your new Optima battery with the red top you removed to see how it fits.
  4. Adapter fittings are behind the red plastic top. Check the fitment before attempting to install the battery to determine whether any of the adapter fittings are required.
  5. As required, attach the adapters to the front and back of the battery. They should enter without difficulty straight away.
  6. Make sure that the positive (+) and negative (-) sides face the same direction. Next, insert the plastic piece that secures the battery. Make sure everything fits snugly and securely.
  7. Put the nut and bolt back on using your socket wrench and the 13mm socket that is attached to it. Check to be sure the battery cannot move or come loose.
  8. If you have insulators, put them on.
  9. Reattach your positive (+) battery terminal, then use your 13mm wrench to tighten it. Afterward, connect your negative (-) terminal (13mm wrench too).

Resistance to Vibration

Under vibration and shock conditions, the battery pack construction may be harmed, and the electrical connections within the battery pack may become unstable. 

Red Top batteries have nearly double the longevity of comparable lead-acid batteries. In addition, the current output is substantially higher during the first 1, 3, 5, and 10 seconds of a beginning than equivalent lead-acid batteries. 

Because of its consistent performance, the battery maintains the same degree of operation even when depleted. Optima Red Top batteries are suited for seasonal usage; a fully charged battery may start a car after a year of inactivity. They are suited for demanding applications since they have 15 times the vibration resilience of ordinary lead-acid batteries. Optima Red Top batteries are leak-proof and may be put almost anywhere. 

Battery Life

How long will my car battery last? The answer is complicated and subject to change depending on various variables. However, because we have repeatedly demonstrated this in laboratory testing and real-world applications, we can confidently state that this battery will live up to twice as long as a conventional flooded battery. This general response does provide some insight into the potential battery life.

All batteries are vulnerable to extreme temperatures, dramatically reducing their life. You can help your batteries operate at their best and last as long as possible by keeping them fully charged whenever possible. To maintain any 12-volt lead-acid battery fully charged and ready to go, you can use Optima 8020-164 35 RedTop Starting Battery.

This battery design innovation provides greater power and surpasses traditional flat-plate batteries. As a result, a battery the size of a standard vehicle battery can start big diesel engines. In addition, a Red Top battery is exceptionally tolerant to vibrations and shocks and can be readily put anywhere.

Final Verdict

During the lifespan of your automobile, you’ll probably need to replace the battery once or twice since repetitive charging and discharging and exposure to heat lead it to age or wear out. A dead battery may be a big pain, especially when you have to wait for roadside assistance or can’t find your jumper wires. 

Redtop Battery is a one-of-a-kind design that provides 15 times more vibration resistance, more efficient starting power, longer battery life, high heat resistance, more operating duration, faster recharging, and longer service life in deep cycle, maritime, and beginning applications.

Optima 8020-164 35 RedTop Starting Battery is developed for use with winch motors and other short-term, high-current tasks like starting engines. So naturally, they dislike being “deep cycled,” but the Red Top battery’s SpiralCell Lead Plate Technology means that it will fare far better when subjected to the odd deep drain, such as when you leave the lights on or winch until the battery dies. 

Because SpiralCell technology can store more energy for given battery size, these batteries are perfect for use in off-road vehicles where weight reduction is essential because this battery would require a much larger “conventional” battery to provide the same starting current capability.

Not to worry about your battery again in some bad weather conditions or when it is exposed to some vibrations that affect the lifespan of your battery, Optima is here to serve you.

Review: These batteries are great during the warmer months of the year but you will want to disconnect them on cars stored during the winter or keep a trickle charger on them to avoid deep discharges. If you treat them right they will last for 6-8 years in my experience which easily justifies their price and generally they are a bit lighter than regular basic car batteries. Since they have no vents on them they can be used successfully in trunk locations where normally a battery box or sealed area would be needed.

daniel – ⭐⭐⭐⭐⭐

Review: The first thing I read about this battery was it’s expensive and worth every penny so I watched a bunch of videos on YouTube and Hall gave it high marks, so I purchased it installed it, which was easy. I didn’t use my truck for eight months. through summer fall and winter and when I went out to start it, I brought my jumper. I didn’t need it. The truck frame dried up. The battery was in pristine condition still holding a high charge.

Esteban Quesada – ⭐⭐⭐⭐

Review: I bought this to replace what the auto shops kept saying was a low voltage battery. I just wish that I had payed attention to the dimensions of the battery since it ended up being a couple of inches too short for the hold down bar in my 2016 Toyota Corolla. Also I didn’t want to pay close to $350 for the shop’s cheapest battery and labor. I wanted a quality battery and so far it is holding up to that.

Esteban Quesada – ⭐⭐⭐⭐

Review: Battery was delivered timely but after I installed I had an issue and was reimbursed fully for defective battery.

Michael Bougades – ⭐⭐⭐⭐
