I bought their older set of rechargeable batteries that had flashing red LEDs. They would last about 7 days on my wireless mouse and then I would have to recharge them, this was no issue. Two of the batteries stopped recharging so I bought another set. After getting the new set they no longer have a red LED they just flash blue which is distracting at times, they don't seem to hold a charge for as long. These new batteries only last around 3 days and all of them have already stopped charging. I will be getting my rechargeable batteries from someone else.
Update: The company responded to me and gave a refund after giving me a set of steps to follow. They seemed adamant that the product works well and I could be doing something wrong. I checked the output voltage on my USB line with a volt meter when the charge cycle would start. I realized since the USB extender was so long the current draw was causing the voltage to drop below the required levels to charge properly. Now I just charge them directly off a powered HUB and all the new batteries seem to charge fully now. The older ones have just died from age at this point so overall the batteries are holding up.

Ok output capacity, built in charger, cannot be USB charged while in use, no low voltage warning
Warning: Those batteries output 1.5V as expected, but if they are low and you want to recharge them while powering the device that they are plugged in, it's not unreasonable to think you can plug them into a USB battery pack while they are being used in a device.I did that, and the batteries started outputting 5V which fried the GPS they were plugged into.I'm obviously not happy.I figured that out by using a volt meter after the fact and seeing the battery terminal voltage change from 1.5V to 5V after I plugged them into USBApart from this issue that will hopefully not be a problem for most:I tested 4 kinds of Lithium AA batteries, and I'm putting the test results below.There were the 2nd best (new Xtar are the best, EBL is 2nd best since it has the same capacity but without custom charger)New Xtar: Rating: 4.15Wh, Charge: 5.5Wh, 3.45Wh Usable discharge at 1Ahttps://www.amazon.com/gp/product/B0CF8ZNZ33/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1Summary:* This is the only lithium battery that drops its voltage to 1.1V to give you a low voltage warning. Other batteries I tested just die with no warning. That alone is a reason to select it. I tested it with my garmin GPS and it gave me 2H of low battery warning before finally dying. Very nice!* It is also the battery that gave me the most actual discharge capacity* Seller is not lying about cell capacity (thank you) which of course is higher than actual usable energy due to conversion losses* New charger is unfortunately bigger than the old one and drops the USB-A output feature to use your batteries as an emergency USB charger* Verdict: this is the best battery I tested and what you should buy as long as you don't need a built in charger like EBLOld Xtar: Rating: 3.3Wh, Charge: 5.3Wh, 2.7Wh Usable discharge at 1Ahttps://www.amazon.com/gp/product/B09NLVJDY6Summary:* This is the older Xtar battery.
