5-Pack of Vinnic A28PX 6V Alkaline Batteries (L1325, 4LR44)

Amy: Got these for my dog bark collars. I know my dogs bark a lot but the battery doesn't last very long. I went through a pack in about 6 months - for two bark collars. I did reorder them though because they are reasonably priced.

Aubrey Cowart: I got these to replace the batteries in my dog's citronella bark collar. They work perfectly well, I just wish they lasted longer. I find that if I am really diligent about turning off the collar, I can get a month out of one battery. However, that rarely happens, so I can generally only manage about 10 days. Another thing that worries me a touch, is that the battery is often deformed when it quits working. It's like the negative end pops out a bit. I haven't had any battery acid leakage, but it's something to look out for. I don't know if this is normal, or the consequence of being in a bark collar on a hyper active dog. Either way.

Blondiechick: These batteries are a pain in the butt to find, as they aren't used for basically anything. I was using a bark collar for my pup at one point, not anymore-and this was the battery that it required. I found out after ordering these that one of these batteries was MORE than the price for the equivalent five pack on Amazon. They work wonderfully, there isn't much to say about a review of batteries. However the value for the price is fantastic given the supply and demand of such a niche item. Now I need to find a use for the other four I have left in the pack!

Joe: These batteries fit in my dogs bark collar and appear to work well. I removed a star because the battery I was replacing was also a Vinnic (purchased from a pet store) and it fell apart. These batteries are just a few button batteries wrapped up in a plastic casing so I didn't have to worry about battery acid leaking everywhere which is nice.

I'm hoping I don't have a repeat experience with these batteries (likely a random flaw) but for the price you could have 4 bad batteries and still pay less than what I paid at the big pet store.

I haven't done any voltage/amperage tests but the battery is the correct size and our bark collar functions properly with it installed.

B. E. Sharrow: I tested these batteries immediately upon arrival and open circuit voltage was 6.44. Normally, a FRESH alkaline cell will test out at 1.618 Volts. These are stacks of 4 cells so 6.44 is not the 6.47 one would expect from really fresh stock but it is probably as good as you will get from a warehouse reseller.
Considering the garbage that some reviewers have received from other vendors, and the inappropriate use of these button cell stacks in bark collars that require current surge to trip solenoid valves, these are a good buy for the shocking collars such as the Petiner. If you spend less, you will probably be rewarded in kind.
Most dogs are quite hardy, especially the loud barkers and they could certainly carry a slightly heavier collar that used better battery forms. A couple of AA cells would do the job and be much more available. It will happen, in time. Meanwhile, this source is good.
