I got a couple solar powered battery banks along with some lighted plant pots at a garage sale but the batteries were dead so I decided to repair and repurpose them.
I did not expect much for the price that we paid at a garage sale for these huge LED lighted plant pots. But to me the solar panels were worth every penny anyway so I grabbed them without hesitation.
My wife is using the pots for plants so that is no loss.
The solar panels have two switches on the bottom along with a power wire. I figured there must be a rechargeable battery inside so I set it out in the sun to charge for a few days but nothing happened. The batteries are dead.
Today I decided to open them up and see what type of batteries were inside. I expected Lithium Ion batteries but I think these are older and have old ni mh batteries instead.
There is a pair of 1.2 volt 2200 mah AA batteries soldered together.
I got a battery holder and put in some good AA rechargeable batteries and then soldered the battery holder to the original plug and put the entire thing back together.
I got the original LED lights to work. But I am going to use this solar powered battery pack for one of my security projects.
Maybe I can make a LED lighted epoxy coffee coaster one day with the LEDs.
