Rechargeable AA Battery, R6 Chargeable Integrated USB Charg Batteries 1450mAh 1.2V, 2 Cell Pack

These rechargeable batteries are really nice to have. I have never seen rechargeable ones like these. They are easy to charge. I just plug them into the USB port of my laptop while I'm online and charge them. They can also be plugged directly into a USB charger. The light is red when they are charging and turn blue when they are done. I like that the end cap is connected to the battery so I don't lose it when they are charging. The charge seems to last for quite a while. We use a lot of AA batteries so these will definitely save some money.

They do work in my intended device, which is the hand held controller of an Oculus Go. Regular AA batteries will start it at 99%, where the highest these batteries have charged is 71%, and even left charging overnight, still highest at 71%. About 2hours charge gives me in the mid 60’s%.The recoil string that hold the cap on which is removed for charging, feels like it’s going to snap every time I go to charge them, but has not yet. I’m super careful about taking the cap off because of how it feels. They would still work if the string snapped, but may get lost while charging as the cap would no longer be attached to the battery anymore.

Excellent product, I used these in a 6 hour play session on my xbox controller and after I was done I checked the battery life and still read about 90% charge, I honestly wasn't expecting these to last more than 2 hours. Definitely worth it, especially considering they pay for themselves with all the money your saving.

These USB rechargeable batteries are awesome. I have noticed that the capacity is slightly smaller due to some of the space used for the USB plug and electronics. It charges off any USB port i have plugged into and charges to capacity, not by a set amount of time. Blue and red indicator lights during charging tell if the device is charging, nearing capacity or full. I use a set in my wireless mouse, keyboard, remotes, and my drone controller. I will never have to hunt down my battery charger again.

The concept for these is good but there is a fraction of length difference in the batteries over other ones, there are a touch shorter, as a result whatever gadget I tried them in did not work as there was not a connection. There were loose and essentially dropped out. They are a waste of money in my view.

I like this product because you can recharge them by USB. I use them in wall clocks. As stated in another review,they seem to be a little short,but I have no problem with that.

Holy crap, these are brilliant. Why has nobody thought of this before? Plug them into your computer overnight and you've got batteries. Never buying regular batteries again.

This is only 1.2 volts, not 1.5 volts.
