Re: Recharging batteries in a HP75 Pod Message #4 Posted by Vieira, L. C. (Brazil) on 16 Aug 2006, 9:56 p.m., in response to message #3 by GE
Hi;
I have a battery pack for the HP55 that I have already used in an HP75D. For as long as I can think of it, there is no issue using a battery pack in one of them that had been used (or charged) in the other.
In time: the HP55 original charger is able to both 1) supply the internal circuits of the calculator with regulated voltage and 2) charge the the batteries with a proper voltage value, at the same time. This is why it uses a connector with three connecting points. If you suspect the battery pack is bad and you decide to use it in the HP55 with the charger in order to test it, the deffective pack will not be charged and chances are that the calculator works fine, anyway. I'd try to test the battery pack outside the calculator; I do not think itīs worth risking an HP55 for testing purposes.
Success.
