Question about the MRC 959

[nick f]

I have the 959 for sometime now, great little charger and cheap.

I do have one question, after the charge is done there's always a number followed by an "m", for example "02m" or "05m" are these error codes? If yes where can I get a copy of what they mean?

Thanks

I had a list of those codes a while ago but I forgot where I put it.
The ones I remember:
00: fast peak charge went well
02: slow peak charge
05: ended because of time, did not peak (the charge wont put out more than 2500mah in one sitting and will stop there if it hasn't peaked yet)

[SS Pede]

00 normal peaked battery
01 fast peak
02 slow peak
03 voltage spike
04 high battery resistance
05 programmed time end
06 programmed capacity end
07 timed out
08 discharge code

so after my charge irs done which one to I want to see 00m? What does it mean when it shows 01m or 02m? should I re-peak them?

Thanks "SS Pede"

You want to see 00m after a charge, because 00 means the pack has peaked normally. If it gives you 01 or 02 and the pack is still not warm, I would restart the charge. I remember on my 969 (same error codes as 959) I would always get 02m. Something to do with pack voltage not climbing quickly enough or some weird thing. I would restart the charge often times because it tended to do it after only 5-10 minutes of charging. 01 might just be a regular "false peak," not sure though.
