NiMH battery charging on Oregon 700 - a couple questions in GPS Posted January 14, 2021 Okay, I think I figured the whole mess out. I actually ordered four batteries, and when I plugged a different one into my Oregon, it now removes the battery choice menu AND shows the lightning bolt charging icon. I assume the one battery pack wasn't pushing down the button in the battery case properly. I'll have to look into it. Thanks for everyone's help!
