How to Charge a 6 Volt Battery With Solar Chargers
At one time, solar battery chargers were an expensive curiosity. Now, many models are available at reasonable prices. Besides being good for the environment, solar power can save you money. When you charge a 6 volt battery with solar chargers, the power you use is free. There are a few differences in operation compared traditional chargers, but as long as you bear these in mind, it's not at all difficult to do. Does this Spark an idea?

1
Choose the right type of solar charger. A solar charger should be wired to deliver a 6 volt current and have a "blocking diode" to prevent battery discharge during periods when the charger is not getting much light. If your charger has a capacity of 6 watts or more, make sure it has a charge controller to prevent overcharging, or buy one separately. Do not use a solar charger with a 6 volt lithium ion battery unless it is specifically designed for it. Because of the charging characteristics of lithium ion batteries, a conventional charge controller will not work, and the battery will overcharge and may catch fire.

Get the battery ready for charging. Remove the battery from the device it powers. If it is a lead acid battery, remove the cell caps (the plastic caps on top of the battery). If it's a sealed lead acid battery, check that the vent tube (a small tube to allow gases to escape from the battery) is free of obstructions.

Set the solar panel so it receives maximum sunlight for a large part of the day. Make sure it is placed on a stable surface and protected from wind gusts. If you wish, you can place the solar panel inside at a window, although this may lengthen charging time. Solar panels are weather-resistant, so rain won't hurt them, but you should place the battery under cover.

Set the voltage to 6 volts if the charger has multiple settings. Connect the positive lead of the positive terminal of the battery (and negative to negative). If you are using a separate charge controller, connect the solar charger to the controller and the controller to the battery. Charging times vary depending on the power rating of the solar charger and how much light is available. Follow manufacturer's instructions for estimating charging time.

Tips & Warnings
Solar battery chargers can last anywhere from 3 to 25 years. Maintenance is simple. Keep the solar panel clean of dirt and debris and inspect the electrical connections for wear every so often. Low power ("trickle") solar chargers are ideal for maintaining a charge on batteries that are stored for long periods. As long as the solar panel gets some light, it will keep your battery charged up and ready to go.
