In this review, first, we see what exactly makes this charger different compared to the rest of the CTEK products. The 4.3 charger has a patented 8 step charging cycle. It is a universal 12-volt battery charger with pulse maintenance and small battery mode. It is the deep cycle battery charger.
First, we’ll go ahead and see how the charger can be used in a conventional way. This charger has designed not only for cars but for other vehicles. Such as ATVs, UTVs or anything that has a battery can benefit from the use of the CTEK battery charger.
This charger comes with the variety of accessories which includes, a protective bag for carrying it around, as well as two different options for connecting it to your batteries. Now they have a Quick Connect option with little clamps. They also have a permanent connection which you would connect with the little eyelets directly on your battery terminals. Whenever you want to connect the charger you can plug it right in the end.
Features & Charging Modes:
- This charger can work in all the three modes at the same time. If you have a 12-volt automotive battery that was sealed and needed the recondition. You can go ahead and select all three modes and it will run through the full eight step charging process.
- It is good for long-term storage. Especially if you don’t drive your car very much but if you just want to bring a battery back to a charge or use this on multiple locations.
- One single charger is ideal for the car, motorcycle, snowmobile, lawn mower, tractor, and sump pump.
- It is splash and dustproof, protect short-circuit, non-sparking and has got reverse polarity protection.
In the automotive setting, you will see the indicator panel begin to light up. This particular setting is for 12-volt flooded batteries, and if we hit the mode button one more time, that will bring us into the next phase which is called the Snowflake mode.
This specific mode is for sealed AGM batteries. It is suitable for colder climates. So, if you’re charging in extremely cold weather, let’s say it’s winter and you’re storing your car long term. You’re going to switch it over to the snowflake mode in the automotive series.
The next mode is called the recondition mode, that will allow you to bring back deeply discharged or almost dead batteries back to life. In other cases, you just have to replace them. Chances are that sulfation is actually built up inside of the battery. So you switch it over to this recondition mode manually and this will attempt to bring back and rejuvenate the battery to as much capacity as physically possible.
How to use CTEK Battery Charger?
The CTEK is pretty easy to use. First, quick clamps are definitely going to be the way to go connecting the clamps. Also, the eyelets to the charger are very easy because all you’ll need to do is take the two ends, line them up and press it into place. Now they’re going to be connected. When you’re done charging, all you’ll need to do is to take large orange tab press, that down it’s going to release and you can easily pull them apart. When you plug it in you’ll see some LEDs light up and it will indicate as to what mode it is in now.
For small size batteries press the mode button twice. It’s going to move up to medium sized car batteries. When press it again, it’s going to a snowflake which is for charging in cold weather conditions. It also covers AGM batteries requires the 14.7-volt charging.
Now finally, our last mode is going to be Reconditioning Mode, which will recondition deeply discharged batteries. Just above the mode button, there are eight different indicator lights that are numbered.
CTEK’s Unique 8 Steps of Charging
Here we will look at the steps of the charging process.
- DESULFATION MODE (Step 1): In this mode, it is going to remove sulfates from the lead plates and restore the battery’s capacity.
- SOFT START MODE (Step 2): This will determine if the battery can accept the charge and it will start charging it.
- BULK MODE (Step 3): Your battery will be charged to the maximum current until it’s at approximately 80% of capacity.
- ABSORPTION (Step 4): This is going to charge with declining current until your battery reaches 100% capacity.
- ANALYZATION (Step 5): It is to verify that it can hold a charge and if the battery cannot hold a charge, it will indicate that it needs to be replaced
- RECONDITION MODE (Step 6): It checks the condition of the battery.
- FULLY CHARGED MODE / FLOAT (Step 7): At this point, you can remove the clamps and start your vehicle.
- MAINTENANCE CHARGING / PULSE (Step 8): It will be going to maintain the battery between 95 and 100 percent capacity. It monitor’s the voltage and it will give a pulse when it’s necessary.
- Easy to use with simple instructions.

Best Car Battery Charger – Buyer’s Guide
How to Use a Car Battery Charger?
First of all, it is important to always wear safety glasses when working with batteries. The next thing we need to do is to connect the battery. It’s useful if the battery charger can show you the voltage of the battery or connecting to as this will help you to determine how long the battery will take to charge.
Now select the battery type and size and the type of charge you want, fast or slow.
After that select the battery type calcium, AGM or gel. When the battery is fully charged the green ready light will come on. At this point, the charger moves into maintenance mode and can be left connected keeping the battery ready for use.
Different Types of Batteries
All battery types except the Gel Battery are commonly found in vehicle applications. The great advantage of the latest battery types is their smaller size, lighter weight, no maintenance required and higher power outputs.
Most if not all vehicle batteries are sealed and maintenance-free, this is an important factor that affects the way charges have developed.
Finally, when the battery is completely charged a chemical reaction takes place in the battery. This reaction causes heat and gases that are generated inside the battery. All the battery types used to have caps that can be removed to allow the gases to escape without harm. This is important as the gas is created a highly explosive and can cause serious injury.
Stages of Battery Charging:
Maintenance free batteries require dedicated charge programs to ensure that gassing does not happen. There are several stages of battery charging;
