Hmm... interesting. I try to charge my iPad 3 quite often though, meaning if about 70 - 80 % left of the battery (around 2,5 hours of casual use) I put it on charger and never use it 'till it's full. I also need my iPad to be on full charge in the morning so at night I switch it off. Sometimes I let it drop to around 15% then I do an overnight charge. What I want to say Is that I am trying to keep the battery "healthy" , I could not do much more against a battery explosion. I am not an expert on this field, but I bet the guys at Cupertino are. Only one problem I had with Apple's products, it was the overheating of my 2009 late MacBook Pro while playing World Of Warcraft, which was caused by the dust inside the device by the way, can't blame Apple their computer not clean itself internally (not yet anyway). My dad using the latest iMac after he got rid of the 2010 model, my stepmom her 2012 Macbook Air. Never had any problem. They have been to Death Valley in the USA where the iPad had switched off cause of overheating, not exploded at all though (first gen iPad it was).
