Looking for the best bang for my buck in batteries. Currently using AC DELCO super alkalines I got 100 Pack for around $20 on Amazon and they are just decent(depending on the device.) Not looking for rechargeables(I already use them in some devices.) Cheap one use batteries. I've used many batteries in the past. Looked at a lot on ebay that was 700 AA and AAA for $35 but I don't know if I need that many and some were used.
