SpiralCell Technology

At the heart of every OPTIMA battery is a series of individual spiral-wound cells comprised of two pure (99.99%) lead plates. Coated in a precise coating of lead oxide. One coated plate is positive and the other is negative.

The unique manufacturing process of spiral winding continuous lead plates is far more precision-controlled. Expensive than building traditional flat plate AGM batteries. Custom automated cell-winding machines are required to maintain the close tolerances required to maintain quality and performance. Critical tolerances, temperatures, humidity and automated processes are maintained and constantly monitored.

OPTIMA has built over 100 million individual spiral cells since the early 1990’s.

What’s the difference between OPTIMA RedTop, YellowTop, and BlueTop Batteries?

Optima Batteries RedTop Starting Battery



RedTop Battery

For normal engine starting where an alternator immediately monitors the state of charge and provides energy to the battery whenever it is needed.

This would describe most stock vehicles, including: automotive and RV underhood starting, heavy equipment where starting is the primary function, and diesel vehicles without aftermarket electronics.


Use this when electrical loads are higher than average. Or when the discharge cycle is more than typical engine starting, such as vehicles with multiple electronic accessories and vehicles without alternators. This can also include vehicles with a lot of factory electronics such as power sliding doors and a DVD player. Examples also include: racing vehicles without a charging system. Dedicated drag racers, diesel powered vehicles with aftermarket electronics, and vehicles with inverters, winches, or other accessories.


The BlueTop starting battery (dark gray case) is to be used when a dedicated starting battery is required and it should never be used for cycling duty. Use a BlueTop starting battery for marine applications and RVs when the battery’s only function is engine starting.

The dual purpose BlueTop (light gray case) can be used for both starting and deep cycling. Therefore it is a true deep cycle battery with extremely high cranking power. Uses include: trolling motors, marine applications with heavy electrical accessories, and RVs.

5 reviews for Optima Batteries 8002-002 34 RedTop Battery

  1. Juan

    I only use Optima batteries in my vehicles. The last one in my truck lasted 8 years, and that is in a high desert heat environment; and it did not quit, it just started to crank the engine a little slow, so I got a new battery – still have the old one as a back-up. No liquid acid to leak, spill, or evaporate – truly maintenance free (except you my want to use a charger if you do not use the vehicle much, but this gel-type battery is very good at holding a charge for long periods of time). If you are going to use a battery charger with this battery make sure the charger is rated for this type of battery – gel type, for example the Battery Tender 021-0128 Battery Tender Plus 12V Battery Charger works perfectly with this battery.

    This is my second RedTop and it will not be my last. Sure, a battery isn’t all that exciting, or at least it isn’t until you forget your lights on during a football game. When you return hours later to find that a car that still cranks, that’s when you realize just how good of a purchase you made.The first Optima RedTop went into my wife’s Nissan Altima after her stock battery bit the dust. She took her car into the dealership for an oilchange a couple of weeks after I put it in. The head mechanic came out to meet her in the office when she went to pick up her car. I guess he had never ran into a RedTop, or at least a new one, before because he went on and on about it. He said that it was registering off the charts on their testing equipment. He even said that he would be buying RedTops for all of his vehicles from now on.This RedTop went into my old beater 00 Ford Ranger. I only use the truck when I need to haul something so it doesn’t gets cranked up much. Dead batteries were pretty common before but I dropped the RedTop in it. I haven’t had to jump it once (6+ mo of ownership) even though I’ve used the truck less and it’s cold.I’m truly impressed with this battery and can not recommend it enough. It’s cheaper on Amazon than any of the local auto shops, even with their gimmicky coupons or promos. This model came with a bunch of adapters to help with the fit. While I didn’t need them, I appreciated the forethought.

    These Batteries are Fantastic, My truck starts super fast. I switched from Super Start Batteries in my 07 F250 and won’t buy anything but Optimas from now on. It was a tight fit on the Drivers side since I chose to keep the plastic cover the battery posts were what made the cover fit snug. Other than that the adaptors that came with them worked perfect. Update- I have owned these batteries for about 3 months now and have put roughly 4000 miles on them with close to 250 starts off of them. They are working great still even though my short commutes daily hardly seem like enough time to recharge after the energy it takes to Crank the ole 6.0 power stroke. These batteries do charge a lot faster than the old batteries I had from the local parts store. I will try to keep updating this review if after 12 months or so anything changes. I am incredibly happy that I spent the extra money and bought these over the competitor.

    This is a great battery as everyone knows by now. This only my 2nd one I have ever bought, because they have long lifespans. I put this one in my 2003 Ram 1500, that has the Off Road Package. Though it was a little too small for the battery tray in my truck, they provide adapters to make this battery fit in many vehicles. My truck had the upgraded battery when I ordered it from Dodge new, which was up from 500 amps to 700 amp. This battery though, even blows those numbers out of the water with 800 & 1000 respectively! I installed this along with a new Gladiator alternator and a new Gatorback serpentine belt and it all runs beautifully! I can’t say enough about these batteries and have converted my whole family of gearheads over to the Optima line of batteries. Those people saying that these are overhyped, obviously either got that one in a thousand dud, or they think that batteries are indestructible and abused the heck out of them. Remember, there isn’t a battery on earth that will not eventually die.. It was shipped to me in double box packaging, which very thick foam pieces holding it in place and arrived in perfect condition. You just can not beat Amazons price and ease of shopability with things like these. You go to Autozone and pay 185 for a junk battery that will maybe last one year, or you can buy this and just wait 2 or 3 days to have it.

    Absolute best battery for my 1971 Pantera – no corrosion on the underside of the deck lid which closes an inch above the battery. Original batteries had vented caps – no acid on these batteries so no corrosion whatsoever. I have run these Red Top Optimas for over 20 years – no problems – the old one it replaced was 9 years old and still worked perfectly but didn’t want to push my luck.
