Found it in the Concorde maintenance manual (Document 5-0171 Rev M, March, 2012):Rich wrote:This is potentially true, but the first question is what the max charge rate should be.
"NOTE: THE OUTPUT CURRENT OF THE CHARGING EQUIPMENT SHOULD BE SET AS HIGH AS POSSIBLE. RG SERIES BATTERIES CAN ACCEPT CHARGING RATES UP TO 8C1.
(Their bold print)
C1 is the rated capacity in Ah, so for my RG24-11M, 11 ampere hours, and I can charge it at a constant potential with a current of up to 88 amperes. Those with RG24-15M batteries could charge at a current of 120 amperes. Obviously, this capacity is not available in our aircraft, and, I'm not sure is is wise to do on a regular basis, but doesn't seem to be a problem with the battery manufacturer...
