Solar panel and battery charging/discharging

Hi, I am trying to power some LED decoration from a small 6v solar panel. However, I would like the LEDs to be also on during the night, so working from batteries during night time. I have connected in parallel 3 x AA batteries (800mAh each) to my solar panel (6v, 500mAh), with a diode in between to avoid the battery discharging to the panel. Voltage is fine, and LEDs are working, but I am not sure if during the day, the solar panel is powering the LEDs and charging the batteries, or if the batteries are discharging all the time. If the solar panel is providing more current than required by the LED, does the excess current go to the AA batteries? Is it harder to charge AA batteries compared to AAA, apart from the capacity (mAh) being higher and therefore taking longer? Do I need more mA to charge AA batteries? Thanks, Seb
