Leaking batteries

We have changed from alkaline batteries as we heard that duracell batteries are lasting 10 times longer. But we have purchased batteries and had so many problems our rc car remote control had the batteries in for a month acid started leaking out. Our tv remote, camera an xbox remotes all had to be cleaned out because of leaking batteries. When we tried to complain on the website it wouldn't submit. We are dissapointed in this product it does definately not last 10 times longer.
