Rechargeable Batteries (AA Lithium-2 Pack w/USB Charger)

Got the 2 pack because I needed aa's for my pc mouse and I like to leave it running throughout the night a lot so I was going through a battery every 2-3 days. I've had these for 2 weeks or more and I'm only on the second one. They LAST for a loooong time on a full charge. Itll pay for itself in one month tops.

I use it for my led flashlights. Before this I had to use disposable lithium batteries to get good brightness and wasted money. This battery last longer between charging too. I wished I had found this product earlier.

Just received this, and was disappointed that there is no charger "dongle" in the box as stated in the product description. Yes, there is a charging CABLE (helpful) and a charging BASE (absolutely needed), but the description specifically says a CHARGER. The manual says connect it to your computer, which will work, but not in the application for which it was purchased. Now, I'll rummage through my box of dongles to see if I have one sufficiently capable enough for this and the 4-pack I purchased at the same time. I will update this post when I have some experience with the product in actual use.

I got these for my mic but I tried them for my razor and the performance was night and day. I’m very impressed.

I can say with certainty these are the best batteries I've ever owned. They output 1.5v as opposed to most AA's that output 1.2v. Meaning they do a lot better for tracking oculus controllers with the higher/more steady output. I've logged 100+ hours in Steam VR games, and I honestly dont even know how many out of town on the standalone oculus. If anyone is into VR or has a high drain similar device you should check these out. I'm writing this review several months after I got them and they JUST NOW died for the first time.

Since these are lithium rechargeable they maintain a constant voltage till they are deflected. The only downside is that battery meters for alkaline batteries work by reading the voltage so they won’t tell you when your battery level is low. Just get in the habit od charging them back at regular intervals when you find the average life before they die and you’re good to go. The charger does resupply the cells quickly so there’s not a long wait to get going again in comparison to NiCad.

In my oculus controllers they last a good 2-3.5 weeks but I never really know what battery percentage are they just stay at a 100% until my Controllers don't turn back on so I know to recharge the batteries

Doesn’t have that big of a charge but being able to recharge them is a big plus. Recharging takes a while but still saves money from having to buy lots of the cheap AAs. Makes a nice gift too.
