USB Charger for Rechargeable Lithium CR2450 Batteries

USB Charger CR2450 for LED Candle
(Please note that the white AC power adapter is not included with the USB CR2450 battery charger.)

 

Our very own advanced USB powered battery charger is used in several of our LED lighting kits including the Advanced Flame 2.0 high power LED candle. Its charge circuit utilizes the popular Microchip MCP73831 intelligent Lithium-Ion battery management IC which controls the complex charging algorithms required of Lithium-ion based batteries. This particular battery charger is designed for the RCR2450 and LIR2450 rechargeable lithium ion button cell batteries and is powered directly through any USB port. Two onboard LEDs provide the user with a status of the battery charging. One LED is used to indicate the battery is charging while another LED is used to indicate the battery charge cycle is complete and ready for use.

Although MCP73831 based battery chargers are fairly common, our USB charger is far superior to that of our competitors. In particular, many of the competitors based USB chargers utilize a USB charger using a common 0.062" thick PCB which requires the end user to solder or apply tape to the backside of the PCB board to ensure a proper fit to the USB port as an 0.062" thick PCB board is less than that required for a standard USB connector. Our PCB board thickness is custom designed using the exact thickness required to fit securely and reliably in a USB port. Our USB charger also features gold plating which is necessary as the battery depends on a corrosion-free surface to maintain a good electrical connection. Competitors generally use inexpensive solder plated boards which will oxidize over time creating a poor electrical connection between the PCB board and battery. Finally, our USB charger is priced less than that of our competitors.

The USB CR2450 Battery Charger is not a kit. It comes as a fully assembled and operational unit ready for use right out of the box.
