Great batteries for machine work and measuring Calipers, these are my favorite long last batteries, the button style is the most popular, only issue I had was slow shipping and I had to get some cheap ones to get the job done or lose more money, all things said and done the product is great!

Great Batteries

walmart.com

Well I made a mistake and purchased the wrong battery type although it's technically what was needed anyways yea I have not used it but I'll tell you what, it's energizer and I bet the day I do use it I won't be let down because energizer is always top tier and my go too.

Energizer the brand you can trust

Energizer silver-oxide  button cell battery set of 3.
I had been using LR44 s for a beaded string of lights and the batteries would start dimming after 48 hours of non continuous use.  So, after researching I learned about silver-oxide vs alkaline batteries.  Pros: More reliable and lasts longer. silver-oxide has a stable voltage output until the very end of its life (unlike alkaline whose voltage gradually decreases).   Long Shelf Life: It maintains over 90% of its voltage after sitting in storage for up to 5 years.  Capacity: It packs roughly 138 mAh to 150 mAh of energy (roughly 30% to 50% more than alkaline). Leak Protection: Engineered with premium sealing technology to prevent corrosion and leakage.  Environmental Impact: They are manufactured with zero mercury.  
Cons:  More expensive than alkaline.
Note:  Strongly recommend never buying or making string lights that use button cell batteries.  These are recommended for use in watches or certain medical type devices, etc.  This is basically the same as SR44 (S stands for silver) and same size as LR44, (L stands for alkaline), AG13, GPA76.

100 percent better than generic alkaline batteries

These button cell batteries are difficult to find and I use one in my food thermometer.  Thank you Walmart for carrying them.

Found my batteries.

I needed LR44 batteries. These 357/303 batteries are the equivalent per the internet. I bought them and dure enough they work.

These worked for my little battery tester. I can tell if batteries are good or not with my battery tester.

Batteries what is there to say. Reliable and durable. Packaging is now child proof to prevent swallowing and choking. No instructions on suggested opening of product. Scissors and patience required.

Batteries are inside somewhere

For the price these better hold up. I tired of buying cheap ones that last a week or leak. Will update later. Bought for light up holiday decor.

Expensive little things

Quality is great. However the description states that it replaces LR44 batteries. It did not. The top is different and now I'm out money because the battery does not fit as the description stated. Frustrating!

Battery does not replace an LR44 battery.

These batteries have no expiration date and it appears to me to have been purposely obliterated.
Secondly: there is a clear instruction on the wrapper that they are not retail sales.
Proceed with caution.
