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

Good non-alkaline batteries for clocks. Alkaline batteries voltage will sometimes make a clock run too fast or slow. When i replaced my clocks battery with this battery the time went from ‘too slow’ to perfect.

I live in Alaska, so sometimes getting batteries takes an act of GOD.. but these arrived in perfect condition, they work fine... I have a wall clock that cannot use alkaline batteries due to the fragile quartz mechanism.. this package should last a LONG time!

Classic reliable battery no leaks no issues great value.

bought these because my outdoor clock needed them; my clock still does not keep correct time. Not the fault of these batteries, they at least work.

I needed these Panasonic carbon zinc batteries to power my wall clock per the clock's instructions. This type of battery is uncommonly used, in my opinion, but they sure do the job well! I also made sure to buy this type of battery from a well known name like Panasonic.

These batteries have functioned well in the short time I have had them in use. The 4-packs are convenient, there has been no leakage, and the size has been fine. The battery life also seems to be fine, though I'll update this review if it is higher or lower than expected.The one minor issue with this product is the printed "use by" date. It's stamped in miniscule numbers on the bottom of the batteries, and I had to locate a magnifying glass to be able to read them. The dates were fine, but it shouldn't be this difficult!

Some batts did not hold charge.

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 Amazon here - https://www.amazon.com/gp/product/B09PDPC3HL/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1

Pilas de muy buena calidad. No se revientan como otras.

What I have used so far work just fine and the price was great!

Great price for heavy duty batteries and I like that they come in individually packaged groups of four.
