TIANQIU 50 357 Alkaline Watch Batteries LR44 AG13 SR44W Battery

I used to buy my button batteries from Walmart or Batteries Plus. This model of battery cost me between $3.50 and $4.50 each, depending where I could find them. They weren't always available where I usually shop.I decided to check Amazon for these batteries since Amazon had almost everything else and, low and behold, here they were. Not only were they available, but I could buy fifty batteries for less than what two batteries usually cost me.I was skeptical since these aren't "name brand" batteries. I wondered if they would last very long, if they would leak or if they were just poor quality. I was pleasantly surprised that these batteries lasted just as long and sometimes longer, than the "name brand" batteries I was used to buying.I use these batteries to power a laser bore siter, a laser pistol site and three "red dot" quick acquisition rifle scopes. If my laser site or "red dot" scopes were to go dead because of bad batteries it could be a very sticky and possibly dangerous situation. I not only have to rely on my equipment to "get the job done," but I also have to rely on the batteries that power my equipment.These "off brand" batteries work fine and have lasted a bit longer than the "popular, name brand" batteries. Because of the ridiculously low price of these batteries I can order a bunch and keep enough extras on-hand at work to not only replace my batteries to to also provide batteries for my fellow officers in the event that their batteries wear out.Bottom line, these batteries work as well and a bit better than the "name brand" batteries, they cost a whole lot less and they seem to "always" be available through Amazon, unlike the other stores where I've bought these batteries where it's hit or miss that they'll be in stock. My life and the lives of my fellow officers and civilians depend on these batteries working properly to power my laser site and "red dot" scopes. I would not recommend these batteries to anyone if I didn't rely on these batteries myself.Considering the dependability, superior value, equivelent battery life and ready availability, I'll be buying these and other batteries from Amazon from now on. An additional bonus is that I won't have to drive into town for batteries anymore, saving me a bunch of money in gas.So.....if anyone can find a better battery at a better price let me know. I have a feeling that I won't be hearing from anyojne any time soon.

Need a battery for a watch? $5 who cares it lasts a few years. However, I have a small laser-sight for a handgun that uses four at a time. If it's a duty weapon,BUG or ones CCW (or a pointer for a normal person) it should be verified working each time it's taken out or put up, plus if one's cat likes to chase the dot and and no normal people can see you, one can use up batteries in a few months. (I did get a pointer, just for my cat) So when I bop by the store and they have 3 for $10 and I need four well I remember these things are often cheap on (Ebay) but this time I also check Amazon and at $7.99 for 50 with free shipping (no $25 minimum either) it's kind of a no brainer. Are they the BEST batteries in the world (?) who knows, they work fine and with 50 they should last for the rest of my life.

Well, our Hexbug army should be set for quite some time. These are much, much less expensive than the Hexbug-branded replacement batteries (by an order of magnitude...not quite, but you can get 50 of these for half the amount that you'd get 12 of those for). I installed these into 3 Hexbugs yesterday that had died after heavy Christmas play, and these are still going strong today after a day and a half of heavy play (my girls love those things).None of the 50 batteries that I received seem to be corroded in any way, so I'm pleased with that. All-in-all, I'm more than satisfied with this purchase, and more importantly, the Hexbugs seem to be as well. If I ever run out of these, I would buy them again in a heartbeat.

Value for the money

I ordered a bunch of these in 2014. After just a couple of years, I was already having problems with the batteries leaking in the packaging. After six years, almost 100% of the cells that I pull out have leaked.The batteries do still read close to 1.5V (even the ones that have leaked) but they exhibit significantly reduced runtime.if you buy these, don't buy so many that they stay in a drawer for years. Assume that you'll see significant degradation within a couple of years.

Use these in my humidity monitors which run 24/7. No issues so far.

I have many children electronic books and toys that use AG13/LR44 batteries. The retail batteries are expensive, about $5 for 3 batteries pack. There are many cheap AG13 batteries from Amazon market, I gave some doubt at first. Since 50 of these batteries are sold for $5, I gave it a try. The batteries from this particular merchant are fresh, they last quite long, at least equal or longer than retail batteries. I know the 357 silver oxide batteries have higher charge capacity than AG13, but the 357 silver oxide cost much more. I will use these AG13 batteries for toys and children ebooks, but not medical equipments.

After device I placed these batteries in failed to work, I tested 12 of the batteries, brand new out of the package, with two different voltage meters, and NONE were even nearly at full charge capacity. No product returns accepted, so, buyer beware: you may get duds.
