When I ordered these Granicell CR2032 3v coin batteries, I had no idea whether they were of good or bad quality or how long they would last, but decided to order such merely because the price was very low for a large quantity of them (25 in the pack). I got them primarily for car key fobs (and whatever else might require a CR2032 3v coin battery), and upon receiving them I immediately put one in my car key fob and it worked just fine to power my key fob. However, about 4 months later the key fob stopped working and needed a new battery. While I think lasting 4 months is okay, when I consider that I rarely used such vehicle or key fob during that time (driving it only about 2-5 times a week), such battery simply did not do well at all considering it was rarely used. I think if I were using the key fob daily or mulitple times a day that these batteries would only last 1-2 weeks in such scenario, and would thus require regularly replacing them every 1-2 weeks and going through the entire pack of 25 fairly quickly. Moreover, my experience with these batteries indicates they do not last anywhere near as long as some other car key fob batteries last (literally up to 2-3 years, even with frequent use). Also, some information provided by the seller states these will last up to 2 years in a car key fob, and that simply did not happen for me.
In the circumstances and based on my experience with these, I would NOT recommend these batteries at all, and encourage the Amazon consumer community to use caution when considering this product. Sometimes a product selling in a large quantity with a very cheap price is an indication that the product is of extremely low quality, durability, and capacity. I rate this product as 1 star for these reasons and do not recommend such at all. These batteries will work, but do not last long at all and for such reason they are not good batteries.
