Probably the longest lasting 9 volt battery I have used, very good quality!

These are good batteries for the price. I use them in a scale and smoke detectors. Buy up a years worth at a time and change out when necessary. Every six months is alittle much as many alarms now have 120v main power and only run on batteries during outages. These are great at the price to have a years worth and just buy again when you switch them out!

Fast shipping, great price, great batteries!

good price good battery fast shipment

I bought it for my fire alarm. The purchase was easy and delivery was super fast. Hope it will last long before replacement.

They work great - last over a year in smoke detectors

These came in the US Postal Service very quickly. Price was the lowest I could find. No problems.

We install them in our over 650 members homes in their smoke detectors and since they last so long we have time to spend helping in other ways. When a member wants us to change their batteries we supply them for free and change them all at the same time so we do not have to return to the home for at least 2 years. We have bought almost 2000 of them so far and just got another order.
