this is a good price for the quantity. they last as good as batteries do,.
I had put in the walmart search for rechargeable 9 volt battery's and when i found them I got them. They are not rechargeable and they are week for new battery's. I am disabled and it is hard for me to go and complain so I will have to live with it. I had to make my first correct order with another Co.
very costly but you have to replace once a year in the smoke alarms.....in the carbon dioxide, you must replace the whole alarm! so, it's a necessity.
