    Self-Discharge: The dormant / self discharge characteristics of Pale Blue batteries are very low. This is one of the advantages of a lithium ion battery with a control circuit, vs an alkaline or NiMh battery, where the cell discharges directly into the circuit (no control circuit). The battery life in dormant mode depends partly on the environment. High ambient temperatures, and higher humidity, increases the internal drain. But in normal circumstances a battery installed in a device, like a door lock, will last ~12 months.

    I have these as Christmas gifts. Everyone was impressed by how cool they were.

    not quite Alkaline capacity, but still like pale blue

    I like the Li technology and direct USB charging, However the Pale Blue advertising tends to imply that 1 PaleBlue AA is equivalent to 1000 alkaline AAs. This is just not my experience. I have two led lights, each powered by three AA batteries. I have to recharge my Pale Blues 3X before the alkalines poop out. I know "your mileage may vary" and it depends on the device.
    I still prefer Pale Blues and I have many. I especially line the new higher capacity AAA pale blues.

    Love these

    These are a life saver for my Toddlers battery powered toys!

    AA Rechargeable Batteries

    I recently ordered and received my Pale Blue AA Rechargeable Smart Batteries. Ensured they were completely charged before using. After that, installed them in motion activated safety lights in my home hallway. They are a huge advantage over having to purchase name brand AA batteries. I primarily needed two four packs but purchased three for rotation purposes. I have not been disappointed in the Pale Blue product. They perform as advertised and super easy to maintain. The Customer Support was excellent. Looking into the other products Pale Blue offers.

    Great Product

    Love the batteries I purchased. Love that I can charge multiple at a time and they charge fast. Super quick shipping and great customer support. Will buy more and other types.
