Review on High Performance EBL 8 Pack 1200MAh 1.5V AAA Lithium Non-Rechargeable Batteries - Ideal For High-Tech Devices With Constant Voltage by Sam Carter

Third update (January 2023). I have given these batteries and the company every chance to prove themselves. Sorry, they suck. The batteries die in a doorbell within a month in a device that only gets used a few times a week. And they die irregularly. When the device stops working, usually one or two of the three batteries is fine, but the remainder is dead. So as much as I hoped I would like them, they really last only as long as normal alkaline batteries, at greater cost.Second update (October 2022). The company and the people seem responsive. But the product is crap. The replacement batteries seem no better, and the battery life is so inconsistent. In a door bell with three batteries, one of the three will completely die, while the other two are still 80-100%. This is really unacceptable, and I have to say this product completely disappoints me, and I cannot recommend them at all.I wrote the comments below a while ago. However, I have to commend the company for terrific customer service. They told me that they realized the batteries were not up to snuff, and they sent me a whole new set. I have not had a chance to try the new ones, but as soon as I do, I will update this post again with what I hope is better news of the quality of the batteries. I have to hand it to the company for trying to fix the situation!I bought these hoping they would have longer life than regular alkaline batteries. They don't. These last perhaps even less time, average just over a month. Alkaline batteries lasted average two months. And in the case of these lithium batteries, usually one of the three in the doorbell goes totally dead before the other two, but still making the doorbell useless. Not happy about this purchase.
