Title: Do not last, poor durability
Review: I bought two of these Ultralife 9V batteries and placed each of them in a different outdoor motion detector. The previous Duracell Alkaline 9V battery lasted 2 years. The first one of these failed after 15 days, the second one lasted 4 months. Others have reported poor durability when used in other types of devices. Bad deal due to unproven claims.I guess we need to wait until a reknown company like Duracell or Energizer comes up with a real working version like they have with the CR 123.
