Long-Lasting Duracell Medical 28A Alkaline Battery 6V, 4 Count - Optimal Power for Medical Devices Review

Bought for bark collar, fits as expected. I'll update in a few months and let you know if they're still going strong. I went with the more expensive brand due to complaints about cheaper batteries. I was ticking these few weeks!

Bought for our dog collar (we have an electronic fence line). Fits and works perfectly. cheaper than going to one of those specialty battery stores. This is not usually the case in a normal business.

These are fresh batteries with a 4 year life until the expiry date. I need them - I have two old expensive photometers that are useless without them. are made for medical purposes and work at a higher level, so I went that route. Hard to find in the normal world of batteries - so I'll be back!
