9V USB-C Rechargeable Batteries
• 🔋 Designed to outperform alkaline batteries
• ⚡️ Fast charging with a USB-C port on each battery
• 🔌 Easy to use included charging cable can charge 4 batteries at once
• ♻️ Each Paleblue battery can prevent up to 1,000 single use batteries from being thrown away
Usage In Smoke Detectors
Most smoke detector and carbon dioxide detector manufacturers do not recommend using rechargeable batteries in their products. Always double-check the instruction manual and manufacturer’s recommendations before making the right battery selection. When in doubt, do not use rechargeable or rechargeable lithium batteries in your detectors.

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 9V batteries plug in just like your phone with USB-C. Charge all four 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 9Vs. 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.
