So I think I may have fried the rechargables in my HP-1 by attempting to charge them even tho they were already charged (not on purpose, i guess impatience about wanting to listen and not reading the prompt about "start charging") and now they won't charge at all. So I went and bought a new set of rechargables and am trying to save myself the same headache by calculating the charge time. First question is, what is the battery charge rate current of the Homepatrol 1? and second, is there a way to make it only charge when the battery's are actually in need of it, or is that entirely up to my discretion?
