A good 9 volt battery at a good price and above delivered to you. I compared its autonomy alkaline battery brand distributor and I get about 50% more. I use it on an automatic sprinkler system that I do not want to change the batteries every 4 morning. Moreover, I have not observed this oxidation batteries as I could have on other batteries. But oxidation comes with time. I will update my review if j.observe else.
