Li-Ion Battery Not Charging Completely

Post by DanielObrien42 »

I have this battery pack: Tenergy Li-Ion 18650 3.7V 6600mAh and am charging it with the USB/DC Lithium Polymer battery charger 5-12V - 3.7/4.2v cells, PRODUCT ID: 280. The battery achieves 3.83V but the charger continues to charge (orange chart light) and after 14 hours (safety timer) faults with a red light.

Is this expected behavior?

The product page for the charger warns that it's for use with Adafruit LiIon batteries only.
