Solperk 10w Solar Panel Charger Kit+8a Controller
Another great option is the Solperk 10 Watt solar panel that can safely charge and maintain most 12V batteries including Wet, Gel, MF, EFB, and AGM.
This one also has an 8A charge controller to prevent the battery from self-discharging and protect it from overcharging, open and close circuit protection, and overloading as well.
The charge controller has 3 modes:
- Two indicator lights are on: This means that the controller is connected to the panel, but its not connected to any battery
- Yellow/red lights are on and the green light is off: This means that the controller is connected to a battery and its charging
- Both the green and yellow/red lights are on: This means that the battery is full charged
Solperk 10W solar panel comes with a very durable aluminum mounting bracket that can rotate 360 degrees, which increases the amount of direct sunlight you get.

Pros And Cons Of Solar 12v Solar Battery Chargers
Weve already seen some of the major advantage of 12V solar battery chargers namely versatility, eco-friendliness and durability as most models are intended for prolonged use. Both the charge controller and panel are often long-lasting, highly durable, water and debris proof. As with any device they do also have their limitations.
Pros:
- 12V solar battery chargers are a eco-friendly and cost-effective way to maintain or trickle charge any 12V battery without resorting to grid electricity.
- They are a self contained power source using only solar power to function
- 12V solar battery chargers are quite effective. It takes only around 5 to 8 hours to fully charge a 12V car battery with a solar panel that can produce 1 amp of current in perfect condition though
- Most models are geared towards improved portability making them extremely versatile to use on the go in any situation
- Their application is also highly versatile as you can plug a 12V solar charge controller even while the vehicle is moving, though for better results it would be better to attach the clamps directly to the battery while idle for faster charging times
- 12V solar battery chargers are built to last and to work in all kinds of weathers, season and terrains. All components are highly water and dust-proof
Cons:
- 12V solar battery chargers are still much less powerful and present a slower charging time than regular battery chargers and cannot revive dead batteries

How Do 12v Solar Battery Chargers Work
12V solar battery chargers are best used for maintaining or trickle charging larger batteries such as that of your car, boat, motorcycle, ATV or RV . Unlike standard car battery chargers though, the solar alternative relies solely on the suns rays to power up via PV cell solar panels.
This obviously brings a wealth of advantages as no other source of energy is required, which makes them perfect for charging your battery when youre off the grid but this also brings some limitations. First off, 12V solar battery chargers cannot compete in charging times and effectiveness with standard battery chargers.
You will also be hard pressed to revive a completely dead battery but what they can do is maintain an existing charge or be employed as a trickle charger, supplying a low but constant amount of usable current. Hooking up multiple chargers is sometimes done, but by experts who know the technology well. Be weary of doing this unless you have the appropriate know-how, as you may just fry both the battery and solar charger.
12V solar battery chargers are typically made of two main components: A waterproof and durable solar panel and charge controller. 12V solar battery chargers allow for up to 48V and 4000 Ah of capacity Lead-Acid or Ni-Cd battery charging. A third vital component is the wires that attach the charge controller to the battery via clamps or the vehicles cigarette lighter.

Understanding Voltage For Car Batteries And Chargers
12-volts is the standard for an automobile battery.
Each battery has six cells with 2.1 voltage. When the battery is fully charged, this equals to 12.6 volts of charge in the battery.
If the voltage in a car battery drops, even that 0.6 down to 12.0, theres a 75% difference in power. The power drips down from 100% to 25%.
At 12.4 volts, the car battery is charged to 75%, and 12.2 means the voltage is at 50% charged. That means you can consider your battery charged if it is 12.4 volts or higher but discharged and in need of charging again if its even 12.39 volts or lower.
You can test your car battery voltage by connecting a voltmeter to the battery.
13.5 to 14.5 volts or more should register while the charging occurs with the car on idle. If it is not producing this, the alternator may be having issues and needs to be tested at an auto parts store.
