#1 Optima Batteries RedTop (8004-003 34/78)
Want some hotrod level of power? This Optima Battery RedTop could be an ideal unit. It’s engineered to give you an astonishing starting ability for your heavy use demands. SUVs, sedans, trucks, even hot rods can benefit from this model.
The beauty of this Optima lies in how it can give you high power cranking ability even during unfriendly weather. Expect to have a strong burst of cranking power and can withstand harsh gravity conditions.
Reliable during harsh conditions
Imagine having a battery you can rely on every driving condition. Extreme corners, hard launches, bumpy roads. This battery can withstand all of that.
This battery is designed to act as a clean power source without sacrificing power. A longer shelf-life is ensured by the higher reserve capacity. It’s a promising feature as you won’t have to worry about running out of power in times when you need it the most.
This Optima RedTop is an ideal battery if you want something that can give you a strong and stable power. Being maintenance-free is yet another perk of this model – probably the best part for some.
• Impressive vibration resistance
• Good tech behind
• Warranty concerns
#2 Optima Batteries YellowTop Dual Purpose Battery (8014-045 D34/78)
Excellent cranking power and deep-cycle capability are just two of the many features you can enjoy. Material is polypropylene and has a reserve capacity of two hours.
Premium cranking power is something a lot of vehicles can benefit from. You can depend on this one both in hot and cold weather.
Just like the previous RedTop, this YellowTop also boosts a high starting capability and impressively fifteen times more resistant to vibration. That said, off-road tracks and unforgiving road conditions shouldn’t be a problem when using this battery.
You also get to have the SpiralCell feature you’re already familiar with due to the previous product featured. This technology means clean power for the environment and safety for you as well as your passengers.
Since this unit can resist vibration fifteen (15) times more than conventional brands, it also means the unit can last up to three (3) times longer than ordinary ones.
Red versus Yellow
You might be wondering about the difference between this YellowTop and the previously featured RedTop. The YellowTop boasts deep cycle, meaning you can dedicate the battery for heavy demands including vehicles with high wattage electrical systems such as big sound systems that draw a lot of power.
The RedTop, on the other hand, is for the other vehicles on the road. The temperature range is not much of a difference between the two. Among the two, the YellowTop has a higher risk of shorting if not cycled or charged properly.
• Longer life
• For high demands
• Warranty issues
#3 Optima YellowTop (8012-021 D34)
This model is similar to the previous YellowTop only that it has no side terminals, but it’s really not a downside. Having a top terminal means it will fit large SUVs, trucks, and bigger cars.
More startup power
With 750 CCA, you get one of the strongest startup powers that you can depend on in different conditions. Bad weather and cold mornings should no longer be a problem.
While this Optima looks like a humble YellowTop battery, there’s more to it than meets the eye. Deep-cycle, longer life, and 15 times more resistive to vibration mean you get a dependable battery for your needs.
This YellowTop from Optima is designed for vehicles that have lots of electronics. If you have a touch screen head unit, multiple LCDs, or surround sound speakers, you need something that can support all your electric stuff.

Larger vehicles require a higher CCA than typical small-to-middle-size ones. You can opt with this Odyssey if you require a massive starting power. Deep cycling capability and rapid recovery demands are more things you can expect from this brand.
Modern vehicles are now loaded with more electrical systems than the previous generation. Sound systems, head units, electrical accessories, more lights, and auto computers are examples of things that draw power from your battery. That said, you really need to supply them with the power they need.
This Odyssey is not composed of lead alloys like most batteries in the market. Instead, this one is crafted with pure virgin lead and has more plates inside. Note that more plates equal more surface area which means more power.
While the Odyssey is ideal for large vehicles, this battery can also be used for almost every type of vehicle including 4×4, off-road, everyday cars, and even the classic and antique.
• More plate surface area
• More power
• warranty concerns

Guide and FAQ’s
How to Diagnose a Dead Car Battery?
You woke up and rushed your daily routine because you don’t want to be late for work. Now you went to your garage, went inside your car, took a deep breath, only to find out your car won’t start. Is it a dead battery? You can’t always be sure. Here are some signs on how to tell your battery’s dead.
Engine cranks but doesn’t start
You tried igniting your key but your car only cranks and doesn’t start. While it might be your starter or your alternator, more than 90% of the time it’s because of your battery.
An engine cranking is a tricky symptom. You can use an ammeter and it can say your battery’s good but it can still be a few volts short of what your car needs to start.
Car won’t start and won’t crank
Pretty straightforward. Now this one’s a clear sign that your battery is indeed dead. Your battery is the source of all your electricals, so if none of them works, it can only mean one thing.
Signs of a dying battery
Diagnosing an already dead battery is a relatively easy thing to do. The more important thing to look out for is when it’s still “dying.” There are multiple signs of a dying battery.
• One day battery is good, the next day it’s not
• No lights at all after ignition (from the dashboard to external light accessories)
• Battery dies when the engine is in idle for 15mins or 30mins
• Battery requires jumping every week or earlier
• Car won’t start even after replacing alternator and starter
• Lights and accessories dim
• Car won’t start even after multiple attempts
• Accessories belt squeals when starting
• Hard time starting; needs multiple attempts before the car starts
• Experiences rough idle in city drive (example: traffic stops)
• Squealing of accessories belt when hauling or driving uphill
• Car electronics shut down intermittently (head unit, radio, etc.)
• Accessories and lights blink or dim when accelerating
How long does a car battery last for?
There is no universal answer as to how long car batteries last, but it highly depends on your usage and its ability to get recharged. The moment it can’t be recharged, it’s already dead.
2-5 years for average cars
Multiple factors are affecting the longevity of car batteries, including temperature and humidity.
Let’s say these factors don’t exist and that your battery is permanently in good condition – no extreme humidity, no high temperatures, always a perfect environment for a car battery – you can expect it to last for six (6) years.
Unfortunately, those factors do exist in the real world and therefore affect your battery life. The more realistic answer is – a battery can last for an average of two (2) to five (5) years.
Up to 8 years for hybrid cars
This one’s a whole different story. A hybrid car’s battery can impressively last for up to eight years before you’d have to replace it.
