Just want to make sure you had the fans running while charging it? It's very easy to cook one of these batteries by charging without the fans on.

Higher ambient or battery temperature will affect the peak voltage, so if it was very hot you might see lower voltage. Typically when a battery starts getting full (the first cells get full) it will be at the highest you'll see. As it continues to sit on the charger, the cells which have been topped off will start to warm up and their voltage will drop as their temperature rises. Usually within 2-4 hours of the battery voltage stopping rising is when it's completely balanced, and it will typically have dropped a volt or two in that time.

Does that make any sense?
