Replace Aa Battery With Solar Panel

The portable solar panels that i see have only the usb plugs to deliver power.

Replace aa battery with solar panel. 4 x 2 5 7 1 4 hours. I need to charge only aa aaa batteries is there an adapter connection that i need to have or purchase. Though nimh or nicd will both ensure the proper functioning of your solar lights the installation of non rechargeable alkaline batteries can be the absolute worst choice you can make and should be avoided at all costs. Don t let the flexibility in your battery choice fool you however.

The short answer is that in most solar garden lights you can simply remove the battery cover take out the old batteries which came fitted with the device and replace the battery with a new rechargeable battery of the same specification. If the solar panel produces more power than the battery can handle the battery can overcharge and be damaged. A charge controller helps prevent this from occurring. To replace it open the battery cover on the back of the solar panel and replace the batteries with 4 standard aa size rechargeable batteries.

I don t understand the connection litteraly. Any help appreciated. How long will my solar battery run before it needs to be recharged. Solar fountain batteries typically run for about 4 hours on a full charge.
