I saved 75% on the cost of this battery.
I needed a new battery for my home security system.  The local store priced it at $13.99 for one battery.  I paid $7.99 for two Panasonic batteries at Amazon.  After installation I spoke to the tech support department at the security system and they verified the system was now functioning properly, verifying the fact that the battery was good and doing its job.  I was a little concerned when the batteries came in a small plastic bag without Panasonic packaging.  However it proves my doubts were unfounded.
