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.

    Good batteries when they aren't DOA

    This is my second order that included at least one battery that was dead on arrival and would take a charge. I worked with support for a replacement the first time. Now that it happened again, I'll just reevaluate whether these are worth the trouble.

    High Capacity AAA USB Rechargeable Smart Batteries

    The double and triple A's that I got are fine for things like my computer bluetooth keyboard, gps unit, tv remote, flashlights. I also like that they are rechargable. However, the C batteries were disappointing. I was hoping to use them in some flameless candles, but I guess they don't have enough power to run those. Maybe they are fine in flashlights, but be sure you read the disclaimers before buying these batteries.

    Re-chargeable vs dry cells.

    I purchased Pale Blue because I was tired of devices being ruined by dry cells. They are comparatively expensive but when you factor in devices ruined by dry cells, they are a bargain. So far I have been pleased with their performance. The voltage matches dry cells unlike rechargeable NiMh technology so they are compatible with all of my devices. Only time will tell how good they really are.
