Problem with battery charging on hot days.

My battery won't charge on hot days. I think it might be the alternator belt stretching. I can't think of anything else that could cuase this has anyone run into the same problem and how did you fix it?

if you have a flooded cell battery and removable vent caps, i would start by inspecting the water(distilled or deionized) inside the battery
