Here is what worked well for me. I added a Battery Switch which requires simple technical skills.⏎ Cut the battery's yellow and orange wires, and extend the wires to a switch (DPDT On-On 2 Position Locking Mini Toggle Switch). Here is a sample switch https://www.amazon.com/Uxcell-Position-Locking-Toggle-Switch/dp/B01B7F5UAG I drilled a small hole in the back of the radio for the switch.⏎ ⏎ Now to charge the battery and to use the radio on battery, I enable the switch. When plugged, I turn the switch OFF to save the battery. The radio battery display indicate the battery status (missing when off of course).⏎ Be careful when working with the battery, they can burn if shortened! I hope this helps some others!
