I agree - batteries are a big concern for me here as they just don't seem to last long at all and some I have bought don't even work when the packet is opened! Every main hardware store has told me that as soon as I open the packet then there is no warranty - BUT Ace Hardware at City Mall said I had 7 days to check out the batteries and bring them back if necessary. So full credit to them and that is where my business will go to whenever possible.
