For those of you who have a CHA47 running with dual 9v batteries (alkaline or NiMH), I would like to know how long does a set of batteries usually run for before its depleted.
Because I just got some 9.6 (170mAh) rechargeables from Thomas Distributing and I charged them for 9-10 hours each yesterday. I started using them this morning at around 11am and by now its already depleted. So they lasted for about 12 hours (with breaks in between). Does this sound normal to you guys? I didn't know that the little amp drains the batteries that fast.
