I have a hp-11c and a hp-25, with the 11c once I changed batteries and my calculator was dead. Until yesterday using a small 10 cents coin, sliped the sides of the coin between both sides of the battery spring clips, at the same time with the coin, then reinstalled the batteries (LR-44), and turned it on but I did not see a " Memory Clear ", "Pr Error" or similar message. What I saw is a permanet: - 8,8,8,8,8,8,8,8,8,8

and it turned off until removed the batteries out.
With the hp-25 I had a battery leakage and never noticed until I changed the batteries, the new radio shack batteries charged but, the calculator doesn´t work; with the battery charger conected, the display turns on all digits, varying the brightnees of the leds continously, but doesn´t works proper. I ask for help to fix these problems.
Thanks a lot .
