AAs with 500 mAh capacity and 50 mA charging was a marvel at the time. My greatest invention was that I connected bicycle dynamo directly to a small windmill and upped the voltage with diode ladder. It gave only 50 mA, but alas, that was what those batteries were rated for. Wind blows 24/7 so it was remarkable if you compare with solar panels. https://www.youtube.com/watch?v=XYorx9C-OEE&t=26s https://www.youtube.com/watch?v=XYorx9C-OEE&t=26s
