Backup imperative!
It is surprising that you are totally unaware of how many things we have these days take batteries. We just go along blissfully until the item no longer works. I am continually amazed at at how many of these devices I have. My garage door remote, my item finder, my car key fob, etc.. I have always bought Duracell as it is a trusted brand and I love this four pack, as I am prepared for anything!
Duracell Batteries last a long time!
I received these batteries through the Home Depot Seeds Program. I have several electronic devices, including older watches, remotes, etc., that require various round batteries, including the 2032 such as these. I keep a supply of the 2016, 2025, and 2032 on hand so that I don't have to run out when I need them. This 4-pack is perfect for having enough but not too many. An older watch that I've used for years when working out requires the 2032 batteries, and another one uses the 2025. Can't go wrong with Duracell!

A Thoughtful Improvement.
When I need batteries, my first choice is always Duracell. Duracell batteries always last longer, in my opinion. I needed some Lithium Coin Batteries for a key fob, so I ordered this 4-pack. I received my order and I noticed that Duracell had made a new improvement. They now make there coin batteries taste bitter, so that toddlers will no want to put them in their mouths. That is a Thoughtful Improvement and other brands will hopefully follow. Thank you Duracell for caring about the children.

Duracell Button Battery's
The Duracell button batterys can be found and used in many different items... For me it's what's need to power my meter to monitor my sugar levels. It also used in tools I have, some children's electronics, and countless other items. Duracell is a household name, having been around for years their quality and reputation are un paralleled.. The one thing I recommend is to use caution installing the new battery, as some people secrete natural oils through their skin that others so to be same use a cloth when ever possible as skin oils may shorten the life span.

Features I didn't know I needed!
I've always gone to a local store to get specialty batteries like the 2032 coin cell (I always called them button cells, but coin is probably a better description), but this time they were out, so I ended up online and found this 4 pack. When I opened the package, I was surprised by the literature and packing enclosed. Since I don't have any small children at home I hadn't thought about the need for safety for a battery of this size, but am truly impressed by the safeguards built into this product. KUDOS to Duracell for making the package with plastic on both sides of the battery, not just cardboard on the back, to deter kids from getting into them, and for adding a bitter but safe coating on the battery to discourage kids from putting it in their mouths. I feel a little safer when the grandkids stop by.

Batteries with bitter coating
These DURACELL 2032 batteries were the perfect replacement for all of my car key fobs. Seems to be the most used and most popular battery for other uses as well. Since babies have been known to swallow batteries, these Duracell 2032s are coated with some kind of bitter substance. Packaging is very child-proof. It took me several attempts to open up the double-plastic pockets.

Long lasting
These Duracell CR2032 batteries are so long lasting and fit so many products. We use them for a lot of battery operated items on our home. The great new feature is the child secure bitter coating, so the little ones will not want to put them in their mouth. They also have a tough packaging that is nearly impossible to open with bare hands. They are great for calculators, remotes, scales, etc.

Excellent batteries
I do not often have small children in my house, so the bitter coating on the battery is not a huge selling point for me, but I am all for products that protect kids. Having the bitter coating does not appear to affect the performance of the battery. Since this is a review, and I was curious, I attempted to "taste" the bitter. The cathode(+) side did not appear to have an discernable taste. The anode(-) had a subtle one. I did not put these in my mouth. I just touched my tongue, so maybe I did not get the full effect. I always prefer Duracell to other brands because they always have a long usable life. These appear to be no different. I recommend these because they are high-quality batteries. The bitter coating, in my opinion, may or may not be an adequate deterrent for small children to consume them. It is nice to see that the battery industry is attempting to address this issue.

Great idea
So we have used Duracell button style batteries in numerous devices for years. Now that we occasionally have little ones around the house,having these with the bitter taste option is a great idea. The other thing that I was impressed with was the packaging. It was extremely well sealed in separate blister packs you need to cut open. I know that the performance will be great, the added safety is just icing on the cake.

4 pack of a very common coin battery! The 2032!
The 2032 coin battery is very popular in wireless car keys, garage door openers, and even my watch for officiating soccer. I have all three of these things, so the batteries do need to be replaced from time to time. I can't speak to how long these 2032s from Duracell last and I'm not about to put them in my mouth, but I completely trust that they made them taste terrible enough to help children avoid eating them. I'd just keep them stored away from your kids and keep it that simple. Quality batteries, I think they work just as good as the other competition.
