I have a Trinity reference 3000mah 7.2volt battery. The problem I am having is that it will not charge on my Integy16x4 charger. I have some Venom batteries and they charge no problem But the Trinity battery won't. If I put it on my Hobbico 905 charger it charges fine. The question I have is why it won't charge on my other charger. Any help would be great. Oh yeah it also charges on the charger at my LHS.
