Yeah I remember when Duralock came out and all the hype about it and when I read the disclaimer on the package and the replacement warranty was exactly the same I knew it was all just another gimmick. I told someone if they really thought their "new" cells would be less likely to leak they would have a better guarantee like double your money back or something that shows more confidence in their product. When Coleman started making lights that said you can "lock them out" I shook my head on that also as lights with clicky switches already lock out and it has already been shown that you can make lights with low standby current such that locking them out is not necessary.
