These are a winner!! 6 months after purchase, these batteries are still very good! Have used them in a digital scale, led lights, and car remotes.
Much better to buy bulk than getting less than half the amount of batteries for the same price at the drugstore!

I've gotten cell batteries in bulk before, but have had some bad experiences. Previous ones were stored in a humid place, making the packaging glue fall apart and batteries came into contact with one another for who knows how long. In case you didn't know, these cell batteries need to be kept NOT touching, or they start to lose power. Another time, packaging was intact, but the batteries died in a couple of weeks after installing. (They did not have manufacturing or expiration dates.) Hope the sellers don't change too much. We will be needing 1620s soon

For the price as how many you get, I love them! At retail, you would get about 3 or these batteries, not 20! I use them for my guitar tuners and even the retail models have to be replaced every 6 months even though I only play 1-3 times per month, and tuning my guitar only takes 5 minutes. I did see the not lasting long reviews, but the last time I bought a 5 pack of these batteries was almost 2 years ago and I just installed the last one that past weekend. Maybe the quality has dropped, I don't know, but for 20 for $7 is nothing. If half work out I'd be happy.

I ordered four packages of 5 batteries each and now 8 months later thankfully they are gone. They were for the bathroom scale which gets used maybe twice a week and about every 10 days the battery would go dead. I highly suggest buying a name brand even if they are more. As always you get what you pay for.

i was excited to receive this many batteries (I use a lot) although I tried absolutely every one of them and not a one worked,
I was so disappointed because I had planned on ordering more. Not sure if they were old or what, I was going to send them an email but I just figured chalk it up!

I purchase these in bulk from this supplier because the prices are amazing and the product is good. I purchase them for my father who keeps tea candles lit in memory of my mom...which does consume a great number of batteries. He asked me to reorder them when he was running low...and he's quite picky about what products he uses...so that should say something. I bought a second large batch and was not disappointed in the shipping. Which was quite quick.
