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.
Pale Blue batteries charge 5x faster than conventional Ni-MH rechargeables. Most rechargeables, historically, were NiMh chemistry. They recharge very slow and have a hard time keeping up with any high use applications. NiMh batteries will also discharge when not in use. Pale Blue's chemistry and smart circuitry resolves these issues.
