Important Features of Optima 8027-127 D27M
The Optima 8027-127 can supply your RV’s starter motor with 800 amperes at zero degrees Celsius, for 30 seconds. When operated at a temperature of 32 degrees Fahrenheit, this battery can supply your RV’s cranking motor with 1000A for 30 seconds continuously. The difference is currently available for cranking is because batteries operate better at between 32 degrees and 80 degrees Fahrenheit than at zero degrees Fahrenheit.
This battery has a nominal voltage of 12 Volts. That is the voltage the cells will operate at for a while before it starts dropping to 10.5 volts. When fully charged and not yet connected to a load, this battery attains a voltage of 13.1 Volts.
With an internal resistance of 0.0025 ohms, this battery is efficient. The internal resistance is the opposition the current faces when flowing internally from the cell reaction to the terminal. The greater the internal resistance, the faster the battery will become hot when operating.
It has a reserve capacity of 140 minutes. That is the period the trolling motor can draw 25A of current at a temperature of 80 Degrees Fahrenheit without the voltage dropping below 10.5 Volts. This battery has a capacity of 66Ah C/20, which means if you draw current from it continuously for 20 hours, you will draw a total of 1320A.
Feature Benefits
The Optima 8027-127 is a dual-purpose battery that can be used as a cranking battery for your RV as well as a marine battery for your boat. It can supply you starting motor with 800 amperes at zero degrees Fahrenheit or 1000 amperes at 32 degrees Fahrenheit. If you use it as a trolling motor battery, you are guaranteed of 140 minutes reserve capacity.
That is close to two and a half hours of continuous trolling. With those facts in mind, you can see why this is one of the best trolling motor batteries as well as the best starting battery.
It is designed to charge faster than conventional lead acid batteries. That is achieved by using lead-tin alloy instead of pure lead. What the alloy does is it lowers the internal resistance of this battery’s cells. That allows it to take more recharge current to enable it to achieve its full capacity within a short period. If you do not exceed 14 Volts when recharging, this battery will not be damaged due to fast recharging.
Unlike conventional lead-acid batteries, this battery is sealed and vibration resistant. It can withstand 15 times more vibration than a regular battery. These two factors make this battery one of the perfect marine batteries to use for trolling in rough waters. You will not experience dimming lights that occur when batteries that are affected by vibrations are used in power lights.
You can mount this battery in virtually any position without worrying about spillage. This battery is also maintenance-free. Once you install it, all you have to do is use it and let it recharge in your spare time!

Can the Optima 8027-127 D27M Starting Battery Be Used in Extreme Temperatures
The Optima 8027-127 D27M Starting Battery is designed to operate in a wide range of temperatures, including extreme temperatures. However, it is important to note that the battery’s performance and lifespan may be affected by extreme temperatures, and it is always best to consult the manufacturer’s specifications and guidelines for proper usage in extreme temperature conditions.
Is the Optima 8027-127 D27M Starting Battery a Suitable Option for Deep Cycle Use?
When considering the Optima 8027-127 D27M Starting Battery, it’s essential to weigh the key considerations for deep cycle battery usage. While this battery is designed for starting applications, it may not have the capacity or durability required for prolonged deep cycle use. It’s important to research and compare options before making a decision.
FAQs
Can I order this battery by air, land, or sea?
Yes. This battery is sealed and cannot leak or spill. That is the main reason planes can not transport some batteries. No regulations are barring it from being transported by sea or land.
Is quick recharging okay for this battery?
Yes, this battery can handle faster research. You must, however, keep the recharging voltage below 14 volts. You also have to stop if the battery overheats or you realize it feels hot while recharging.
Can I use any charger available?
No, It is best to use Optima’s recommended charger for the best recharging experience. You must also follow the user manual strictly when recharging.
Insider Tips
If you use this battery to power your RV or for trolling, invest in about four of them to create a battery bank. That will allow your RV onboard equipment or your trolling motor to draw current for long periods. If the batteries are arranged in series, it will also increase the voltage at your disposal. You can then trade the voltage for current when driving your trolling motor.
Summary
The Optima 8027-127 is the best marine deep-cycle battery. It features a CCA of 800 amperes, a CA of 1000, and a Reserve capacity of 140 minutes. It is a dual-purpose battery and is both spill and leak-proof. It is 15 times more resistant to vibrations. It is the best RV battery, and trolling motor battery can have its features.
Conclusion
When it comes to choosing the best battery, in most cases you have to choose between a cranking battery to supply your starting motor with enough amperes, and a trolling battery to power your trolling motor for long periods.
