RE: HP 67 Battery charger not working - any alternatives
I have built a AA-batteryholder for my HP67. I can swap the battery-set at any time against a 2nd set. I charge the batteries in an external charger for NiMH batteries. Eneloop AA-batteries have a capacity of 1900 mAh. The runtime at continuous operation of the HP67 is about 10 hours. Another advantage of eneloops is the very low self-discharge rate (about -10% after 1 year).
