2 month review. These charged great the first time and they did work fine until the battery died. Now they are unable to charge. I bought a new Lithion battery charge and it takes it 15 seconds to show charge. When these discharge to Zero, they can not be brought back to life. I will not purchase again. Really thought they'd be great. UPDATE: These are very good batteries However you MUST use a real Lithium Ion charger. Mine did not work. These are great batteries and store a whole lot of power. Do not allow them to discharge completely. Great product. ****BUYERS Be Aware you MUST get a newer Lithium Ion Battery Charger. Older ones don't fully charge. When using a newer charger they are EXCELLENT batteries. Suggest you DON"T let batteries fully discharge otherwise you'll have to look online and see how to treat the battery to get it to charge. Great batteries. Read more
Very good batteries. Make sure you have a Lithium battery charger as well. These lithium batteries cannot be charged on a Ni-Mh charger. Great customer service received as well! Read more

Two of sixteen batteries were dead on arrival and could not be recharged. Product promoted as “Amazon Choice” but I think not. Manufacturer seems to have poor quality control practices in place. Read more
Well , I have never used a rechargeable lithium battery before, but have used other types of rechargeable batteries, these seem to work okay in my flashlight applications, although they will not work in my outside , solar light system. These batteries require a different amount of power to be charged. So that's totally on me for not researching this type of battery. But other than that I have no problem, as they work in my flashlight just as well as the other batteries have. But I just have to charge them on an approved type of charger. As for the value, i would say, I got a good deal. Read more
I ordered eight batteries. Six of them were fine, registering between 1.52 and 1.53 volts. There was one that was 1.36 volts which quickly went up to over 1.5 volts after a short time in a charger. Not a big deal. However, there was one total dud that registered absolutely zero volts. I tried every trick I know and a few I didn't know from YouTube. The most I got it up to was .18 volts. It's so weak that even using the voltmeter on it draws it down about .01 volts every 10-15 seconds. So I am mainly writing this to ask what I should do. Can I send the one back and get a replacement? That's what most businesses would do. However this is Amazon and my guess is I have to send all eight back. I hope a company rep reads this and can give me an answer. Speaking of the company, I couldn't find them on the Internet, so when Amazon tells you to talk to the manufacturer if there are problems, you can't do it. If I could get one replacement battery for the dud, I'd be happy to raise my evaluation to 4 stars. It would be five stars, but apparently there's a huge problem with duds with these batteries. I have ordered many rechargeable batteries of all kinds over the years and I've never come across one that just didn't work like this one. Avoid hassles -- use another manufacturer. Read more
