Optima 8016-103 D34M BlueTop Battery | Review 2020
Optima 8016-103 D34M is one of the top rated marine battery for small boat and trolling motors. Unlike most batteries that you can only use for either deep cycle tasks or engine starting applications such as cranking your RV motor, this battery can do work both ways. I also leaned something else while charging this battery. It can take as much current as 100A without overheating when giving it a quick charge. Some batteries would just be ruined if you attempted to pull off something like that.
On the first day of usage, I was amazed to have used it for a whole hour, running my trolling motor continuously. When I measured the how much charge was left. I was surprised to learn that I had only used 25% of the total reserve capacity. I gave it a quick charge to get it to full capacity again. So I decided to write this review:
- Cell Plates made of pure lead-tin alloy;
- Sulfuric Acid Electrolyte;
- Color Blue cover and light gray case;
- Battery Council International (BCI) Group size 34;
- Dimensions: 10.018 inches by 6.829 inches by 7.925 inches;
- Weight 43.5 pounds;
- Fully charged voltage 13.1 Volts;
- Capacity 55Ah;
- Reserve Capacity 120 Minutes;
- Cold Cranking Capacity 750A;
- Marine Cranking Capacity 870A;
The Optima 8016-103-FFP D34M is made of pure lead-tin alloy which is great in taking large currents without overheating. These plates are also able to react with the sulfuric acid without forming an oxide coating, which is a big cause of battery failure in most wet acids batteries.
The small size and weight of this battery do not overload your boat even when you have several of them. Its small compact size is great when you want to build a battery bank, but you do not have much space to spare.
With a capacity of 55AH, it can discharge a constant of 55A for one straight hour. It can discharge a current of 750A for thirty seconds at Zero degrees Fahrenheit, or 870A at 32 degrees Fahrenheit.
The 120 minutes reserve capacity means this battery can discharge 25A when operated at 80°F (26.7°C), for 120 minutes before the voltage drops to 10.5 volts.
AS a D34M battery, this battery can power a large vehicle with many on-board accessories without damaging its cells.
This battery is sealed and features a recombination technology. That means the battery is not serviceable, and can be used in an enclosed environment.
This sealed battery affords you the luxury to use it without fear of an explosion of leaked gasses. As long as it is not overcharged, you can depend on of its recombination technology to withhold and manage its gasses. This battery will also not spill its electrolyte if it is accidentally tilted. You can ride your boat without worrying of rough-rides harming your battery.
If you have a need to manage your space due to the small size of your trolling boat, this battery is designed for you. It is small in size and compact enough to fit tight spaces. It is light weight, and will therefore not overload your boat.
Most of the times, batteries are heavy, something that eats into the battery power if you use it to drive your trolling motor. This battery does not fall into the category of such batteries. It is light for its power output, making it very efficient and the best for trolling motor.
This battery being a dual purpose battery means that you’re free to use it to crank your motor or troll all day. You may use it to power your RV’s onboard equipment if you need to. Many users consider this battery to be one of the best electric motor boat use, not because of its sheer power alone, but also because of its ability to recharge quickly.
Unlike regular lead acid batteries, it does not heat up when you charge it with as much current as 100A. All you have to do is make sure the charging voltage does not exceed 15 Volts.
If you recharge it with 100 amps, you can expect to attain 90% charge capacity within 35 minutes. That is an awesome fit by all standards. You can take your lunch break, and by the time you are back, your battery bank is 90% full!
