In the past (and when on sale) I would buy ROV batteries...and they would always fail prematurely for me. Then I would think to myself, how could a big company still be in business that made a faulty product. So I would try again. Last time was a 5 year rated lithium 9Volt I put in a smoke detector...it failed (detector started short beep) after 2 weeks!
I don't have problems with Duracell or Energizer. (I don't own stock in these companies)
