New 200 X AG3 LR41 392 Button Cell Battery in Tray

What I like: there’s a lot of Batteries, just peel back the cover tape to remove battery. Perfect fit for the Lighted pens. I have a hundred pens that need batteries replaced so the best value for the money was a deciding factor. The quality of the batteries shown through how bright the pens glow !!!

First three used are working well. At .04/battery with free shipping, what's not to like?

I use these batteries in promotional flashlight pens that we give away. For some reason, a number of the promo pens came with defective or leaking batteries from the manufacturer. I used these batteries as replacement batteries. They were a perfect replacement. Good voltage and virtually all of them were in good condition.The only problem I found is that the batteries are held in their packaging with clear transparent tape as seen in the photo of the item. That tape leave a residue on one side of the battery that sometimes prevents a good electrical contact. I find that I have to manually wipe the sticky residue off the battery to make the flashlight work. It takes time and effort as these are very small batteries.If it weren't for that, these would be a solid 5 star product.

batteries seem to be fresh! as they last longer than the OEM ones that came in the light sets!

Bought for my laser and they fit. I'm sure they will last and stay working good.

. . . at least I don't have to look very far when I need new batteries!

I purchased balloons LED light last year to put on my cat collar for night safety.(I do have LED glow collar, but it only last 7 hrs at most. ) I was gonna buy same items but I realized that all I need are new batteries, every other parts are still perfect. Batteries cost so much less. And maybe... new butteries are better quality (longer lasting). Well it last about the same hours ... Sundown till morning. Good enough for me.

Muy buen precio
