    • Rechargeable batteries
Size: AA Li-ion 4 Pack
I've used these batteries for my home appliances and they work well. Great value for money. I bought more expensive batteries that didn't last half the time these did. I'll be a return customer. You have to know they're rechargeable because the packaging of the actual battery doesn't say it... don't be tempted to throw them away. ... show more

    • I have the Olight Ostation2 charger also
Size: AA Li-ion 8 Pack
These batteries work well and seem to have good life, I also have multiple other OLight devices. Good products all. I did initially make the mistake of purchasing some other "no name" batteries. Big mistake as they do not hold charge very well, so I am transitioning off the "no name" batteries to the Olight brand batteries. Now, if OLight will make AAA batteries like these...I would buy them also. ... show more

    • Works
Size: AA Li-ion 8 Pack
Charges with olight charging station. It's slightly bigger than regular AA. It will not fit well if whatever your placing them in has tight space. Like airthings wave gen 1, 2. I think it's a little short and little fat. I am talking <.1mm. So far working for few weeks and battery is still showing full. Might be good to buy from known company then random overnight AA lithium companies. If they last more than 500 charges then worth the money. It's AA, so can used in any AA device. Better than NiMH as voltage is steady at 1.2V vs 1.5 of this battery. ... show more

    • Dead after a week.
Size: AA Li-ion 4 Pack
Have only used 1 battery so far. It was 1.5 volts right out of the pack, so i assumed it was fully charged. Put the battery in a wall clock, and it was dead in a week. Alkaline batterys last a year in this clock. I recharged the battery and it is back to 1.5 volts. But if it only lasts a week what good is it? Hopefully the other 3 batteries in the pack are better. Updating my review to 4 stars. Seller gave a full refund, said the battery may have been a bad batch. ... show more

Very nice and function well. BUT, they need a 1.5v Li-ion charger, not one specifically for NiCad or Ni-MH.
