Query: Dangerous Meltdown

This charger worked great for 4 weeks.And then it happened! I Put 2 aaa NIMH Batteries in to be Recharged. Went to take a shower and when I came downstairs I just thought I would take a look at the status of the batteries. To my horror I saw 2 batteries with the acid leaking out of the jacket of the batteries! little bubbles of acid coming out.I turned it off but by this time it was so hot i had to use a paper towel to remove them! after that,I noticed the bottom of the charger where the batteries lay was melted! WHAT!!! I called LACROSSE and they told me to send it back.I have another one on the way,ACCORDING TO THEM but i don't know if its a new version or not.It will be here in 3 days. if its the exact same one, I don't want it! What would have happened if I wasn't home? I will update when I get it.
