Panasonic 20pc AA Batteries Super Heavy Duty Power Carbon Zinc Double A Battery 1.5v...

I ordered these "Carbon Zinc" batteries for a clock that required them. Unfortunately, I had to return the clock for manufacturer's reasons. I have not had them long enough to see if they last longer than other batteries. The price was within reason and the delivery was very quick.

I love them

Perfect for my wall

If you have batteries that leak in certain devices, especially if you just put batteries in then leave them like in seasonal things you only take out once per year or toys/devices which are very infrequently used, then switch to these if those batteries leak. They won't last as long as normal alkaline batteries (not a huge amount less), but they absolutely will not leak, damage things, or cause you to clean up green/white gunk from leaking batteries. My smart door lock makes batteries leak with EVERY set of Energizer and Duracell batteries I've run through it, except for expensive lithium batteries, but lithium have a less-predictable lifespan with the way the chip is programmed on the lock...they show up as 70-100% then quickly drop. Other batteries, like these, have a linear drop in a more predictable fashion, and for some reason the lock also advocates against lithium batteries. I'm glad I have these!

Purchased these recognized brand Panasonic carbon zinc batteries for 4 analog clocks used to track various time zones in office. Batteries look legit produced by Panasonic and so far 4 of 20 batteries still working perfectly. In fact I set clock second hands almost the same when installed batteries for the 4 clocks and a weeks has passed and second all 4 clocks still perfectly in-sync! Of course this is partly due to accuracy/quality of the 4 clocks but this also shows the batteries are providing precise amounts of energy output to the clocks! Highly recommended carbon zinc batteries (good for analog clock accuracy) as my experience so far shows very good value for quality and amount of batteries. I've included a picture of the 4 clocks these batteries are being used in and you'll notice keeping the same second hand accuracy. The 4 'HZDHCLH Modern Wall Clocks Battery Operated,10 inch Black and Gold Clock for Wall,Silent Small Wall Clock for Living Room Bedroom Kitchen Office Nursery Decor' clocks I mentioned and shown in the photo was also purchased on ZeeBooth here - https://www.ZeeBooth.com/gp/product/B09PDPC3HL/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1
