   I purchased these specifically to use in a Flume2 water sensor, as battery replacements directly from the company that makes them make it quite an expense to own buying their proprietary battery packs. I followed online forums on how to do this, and so far they are doing great inside the sensor. Since these batteries are 1.2v and normal AA batteries are 1.5v, the battery status on my phone app shows them as low, while they show full on a browser dashboard status. I believe this is inherent to how lithium batteries have a constant draw at 1.2v while normal alkaline ones gradually drop from 1.5v to 1v. That seems to fool any battery status algorithms into thinking the battery is low when it’s actually fine. That aside these charge up easily (you need to have your own charger and USB C cable) and have worked with no issues so far. Definitely happy to be able to use these as a solution to a problem I was having that will end up saving me a lot of money!

   I’m 74 years old, so I’m not some kid that’s wet behind the ears. I know a thing or two. Regarding batteries, you always want to have a nice supply of AA batteries on hand, because you never know when you’re going to need them.I’ve had several of these units, not necessarily by the same company, but my experience over the years is that, even though it’s frowned upon, I just keep these cubes plugged into a USB socket 24/7 with batteries in them. It seems that the protective circuitry does a really good job at maintaining the batteries at near full capacity without doing any damage to them. I will say I know it’s not a good thing to keep a battery at full charge, but it’s really nice to be able to just grab a few batteries when needed. I don’t recommend other people doing as I do, but I’m telling you it works for me.I highly recommend this system for anybody that goes through a lot of AA batteries. You can thank me later.
