Long Lasting for Garage Door Keypad
I use a 9V battery in my garage door keypad. I do not use the keypad often so I need a battery that can last many years through all outdoor weather (hot and cold). These are more expensive than regular alkaline 9V batteries but over time the cost pays off with longevity.

I Should Have Returned
The package had been previously opened and poorly resealed. I should have returned it for a refund. I bought it for a remote control, used it for 2 weeks and now the so called 10-year battery does not function.

the batteries didn't have a far enough expiration date.. not powerful enough for a safe lock
