Good quality product

Good battery for the money. I purqchase these to replacce all the batteries in my smoke detectors. They easily last past the every 6 month suggested change time on smoke detectors. I also use this battery in my keyless entry garage side door lock and it last at least 1 year.

I'm never quite sure what to write on items that don't need a big description, but essentially these work well, snapped right into my smoke detector, and stopped the annoying beeps. Good value for the money, would purchase again.

Excellent
