Best 2 Bank Marine Battery Charger Reviews For 2018

For those of you with boats with two 12-volt batteries, a 2 bank marine battery charger is needed. Why is this so? Because if you get a 24-volt battery charger that only has one bank and then charges your two batteries with it, what will happen is that one of them will be charged more while the other will have an unbalanced charge. You don’t want this to happen to your batteries.

With a 2 bank battery charger, you will get plenty of advantages as well such as desulfation, recovery, and maintenance processes. This charger connects to each of the batteries independently while giving them both equal and consistent power. This ensures that your batteries will work efficiently and excellently. While this type of battery charger may be more expensive compared to a single bank, it will definitely be worth the money.

What to Look for

When you are shopping for a battery charger, don’t just pick the first one you see. Try to assess the different 2 bank battery chargers, so you will see which one is the best among them. Get one that is designed to charge fast and can maintain your battery even after charging it.

However, what if you won’t be using your boat for some time, especially during winter? If you do not maintain your batteries properly, they may go flat, and ending up with dead batteries will cost you money as you will be needing to buy new ones.

To stop this from happening and to make sure that the batteries that you have will be ready to provide power once you will be using your boat again, connect it to a boat battery charger. This charger should be able to maintain the battery while your boat isn’t being used.

It’s not enough that you buy any kind of boat battery charger. Choose a smart charger that can maintain the batteries over extended periods. Also, select one that is designed to withstand the wet conditions of the sea or lake. This will definitely save you more money than buying cheaper ones.

It’s best to invest in a boat battery charger that can last long and can be used in tough conditions. Buy a boat battery charger that is completely sealed and waterproof. You will be sure to use this charger for years to come.

Another thing to check with your charger is if it is mountable. Make sure that it can be. When you can mount the charger, it will be much easier to use and connect when you will be charging or maintaining your batteries.

Eight-Step Charging Process of the NOCO Model Genius GEN2 Charger

STEP 1-2: Analysis and Diagnosis
This part of the process checks your batteries conditions including its health, state of charge, and voltage so as to determine the stability of the battery before starting the charging process.

STEP 3: Recovery
The charger begins this stage with the desulfation process if it is necessary, especially for sulfated of deeply discharged batteries. The charger sends out a pulsing current to the batteries in this step.

STEP 4: Initialize
The charging process begins with a soft and gentle charge for the batteries.

STEP 5: Bulk
For this part, the process will depend on the battery’s condition, returning 80% of the capacity of the battery.

STEP 6: Absorption
On this step, the charger brings the level up to 90% as it delivers a bit of current at a time, providing an efficient and safe charge. With this, the gassing of the battery is limited. This is important in prolonging the life of the battery. The charger then shifts to a current charge rate that is constant so as to bring the batteries closer to a 90% charge.

STEP 7: Optimization
This step finalizes the process of charging by bringing the battery to its maximum capacity. Here, the charger uses multiple layered charging profiles that can recapture capacity fully and then optimize the particular gravity of your battery. This increases its runtime as well as performance. If more current is necessary, the charger shifts to Maintenance.

STEP 8: Maintenance
Finally, the charger monitors the battery continuously, determining if maintenance is necessary. If your battery’s voltage falls, the charger will initiate this phase until the battery’s voltage will reach the optimal state. After that, the charge cycle will be finished.

The phases of Optimization and Maintenance can be repeated a number of times to make sure that the battery is fully charged. You can leave the charger connected without worries of overcharging.
