Re: Motorola NiMH Batteries Message #5 Posted by Randy on 11 Mar 2009, 9:54 a.m., in response to message #4 by Juan J
Quote: Fortunately I have the HP Reserve Power Pack Charger, and I do not charge batteries within the calulator. Using it helps a lot, no worries about fried ICs.
The "Reserve Power Charger" is a totally passive device, all the electronics are within the wall plug in so there is no difference if the batteries are in the calculator or reserve pack, it is not advisable to charge NiMH cells with either method. A proper, external NiMH specific charger is the only solution.
It is 100% safe to operate classics without card readers from the charger with no battery in place. Stated in the reverse, the 65 and 67 must have a battery in place to operate safely with the charger connected.
Hope that helps.
