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.

Charge on
Skip the docks, cradles, and wall clutter. Paleblue C batteries plug in just like your phone with USB-C. Charge two at once with the included cable, wherever you are. No special gear. No confusion. Just a smarter way to power what you already use.
Power that lasts
Paleblue batteries are designed to replace 1,000+ disposable AAs. That’s more money in your pocket and a lot less waste.
Safe by design
Every battery is engineered with a multi-layered safety system: built-in overcharge & undercharge protection, thermal regulation, short-circuit control, and more. Your devices stay protected no matter what you're powering or where you're charging.
