What ya looking at of mine and from what I have researched and from reading on here other people getting batteries that were so called new or a few months old I am just going to buy brand new batteries from online so I have a good warranty and know that I am the one and only owner and they are for sure brand new so batteries are something I will pass on thanks thoAny interest in 3 Deka 9a31 batteries? Bought in July, have two Kicker KX850.4s too
