A different kind of rechargeable battery.

With our advanced lithium rechargeable technology, Pale Blue batteries charge 5x faster than conventional Ni-MH rechargeable batteries. Pale Blue batteries provide higher power and more consistent output through their use cycle.

Most smoke detector and carbon dioxide detector manufacturers recommend not using rechargeable or rechargeable lithium batteries in their products. Always double check your smoke detector and carbon monoxide detector instruction manuals and manufacturer’s recommendations before making the right battery selection. When in doubt, do not use rechargeable or rechargeable lithium batteries in your detectors.

Benefits:
- Fast Charging Lithium Battery: 1000+ Charge Cycles

- Operating Temperature Rage: -20c -> 60c, (-4F-> 140F)
- 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.
