Assuming you have a MAHA/Powerex MH-C9000, for charge I would use 200 mA or 500 mA, if you have the time, and 1 A otherwise, and sparingly 2A if it's going to make your life better with operating time. In general in seems lower charge rates generate less heat and that's good, but 1A isn't really a problem. The MH-C9000 sets charge with current, and then decides when it is done. It will show you the charge delivered to each cell. The internal charger is low rate and time only. That seems fine too. I also recommend doing a "refresh-analyze" cycle, 200 or 500 mA charge, 200 mA discharge, and recording the results (and putting labels on each cell) when you get them, and every year or so. I have found that batteries that aren't tested can't be relied on long term. 73 de n1dam ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
