    The 9 volt batteries work as expected. I bought a pack to replace batteries from car remotes to house smoke alarms--they all worked as expected. Great value pack for the money.

    These are great for smoke detectors batteries in your house. Worked on night lights for the kids and some flash lights. Cant beat the price for the pack of batteries to have spares.

    For at least the same price or less. You can really go with the Store Brand and Save Money. It did the trick and is still good for what I need.

    I always buy insignia batteries, because they are much cheaper than any other brand. They seem to last just as well as other brands.

    Inexpensive and gets the job done, one of those items that you can grab before you pay. Used the batteries for small portable electronics and smoke detectors.

    Appear to be great batteries

    I bought these to use in the few devices I have left that annoyingly use 9V batteries. No problems so far with these new batteries. My package had a "best before" date of Aug 2022 so I was happy to get one that hadn't been sitting on the shelves for years (I did a same-day in-store pickup). I tested open circuit voltage on all 12 batteries and they each measured exactly 9.76 volts, which isn't any indication of capacity but certainly shows consistency in manufacturing and more than adequate initial charge (9.76V is actually a bit on the high end in my experience). Hopefully, their long-term performance will be great.

    Under a $1 each for 9v Alkalines??? Great deal. They appear to be fresh, no fitment problems in any of several devices, no leakage and they hold a charge.

    9V batteries are hard to find at a great price. This was an excellent deal for the money. So far they are performing as good or better that the name brands. Pleased.

    Picked up a couple of these..hard to beat the price and they last pretty decent in most devices. Nothing like having a few extra around the holidays when needed.

    Great 12 Volt batteries for those tools and alarms

    Replace your smoke detector batteries at least once a year if not twice, it's cheap insurance. Also, who doesn't have a multimeter, studfinder or similar tool that needs these? (If you don't have one, you're missing out - those are crucial tools for any hobbyist or homeowner.). These worked great and were a good value when I got them, too. Kudos to BB for putting them on sale, and when they do, I recommend picking them up for those times when you'll need them.

    Price is very good and the power of the batteries last pretty long for a ''no name brand'' unlike Duracell, etc. Would definitely buy again.
