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.

    So easy to charge…longer lasting…and they just plain look cool. I love these and will be buying more.

    Good product

    I love this product so far and I also love that we are saving the earth in the process

    Long life between charges

    I use these in my helmet light. With NiMH batteries, they would die after 10-20 minutes of us. Pale Blue's go for 90-100 minutes!!!

    AA use

    I've been using the AA batteries in my XBox controller and they have been performing perfectly.

    Great Batteries

    Batteries are easy to charge. The charging indicator makes it easy to see when they have fully charged.
