Hi All: Found: An excellent source for inexpensive HB batteries. They are new 2 AA (800mAh) cells in series for US$0.99 each. I bought 12 of them for $7.14 ... connected four of them in series and added a female connector ... added a male connector (...) (25 years ago, 25-Sep-99, to lugnet.robotics.handyboard)
