15 Alkaline Battery 6V A544 4LR44 PX28A

Good product 👍

A great value! I use these in a door bell alarm which notifies me that customers have walked into the office. I haven't had them long enough to tell how long they last, but they worked right off the bat and have been going without any problem.

These don't last quite as long as the name brand, but for the price, they are well worth it.

Batteries don't last long at all. Item I received does not look like this photo, rather  this item . Realize that I used these to replace batteries that came with a few collars I'd had for a few months. Those collars worked for occassional use over that period of months. When using these batteries, I must install a fresh one about every week -- even using only once per week. No change in how I operated the collar, as it doesn't have a power off, just a sensitivity dial... this item

I buy these for the dogs' bark collar. We seldom put the collar on one of the dogs (I have a problem with another dog can set off the collar so the one wearing it gets punished for their misbehavior, the neighbor's dogs will come over by our kennel and bark at our dogs, not nice.). I mostly will just hold the collar up when I yell out the window to remind our dogs to quit barking, as I yell it makes the collar beep and the dogs remember it and will behave. I have learned that I have to remove the battery because otherwise household noises set it off and when I want it, the battery is dead. I can't imagine that being any different if I purchased a more expensive battery. On the rare occassions when one of the dogs wears the collar, the battery is oftentimes still working when I remove the collar.
