Hi folks,
I have MAHA C9000 and SkyRC NC2500, both come with the break-in program (0.1C charging for 16 hours--> rest--> the 0.2C discharging -->rest-->0.1C charging for 16 hours again, then terminate).
Since this break-in procedure uses a 16 hour charge without regard of any commonly used termination signal (dV/dt, temperature, voltage limit, etc.) -- and only thing the charger uses is to (1) calculate 0.1C, (2) go on for 16 hours. Nothing else in the equation.
So I always think it will be different if the initial charge the battery has before it is put into the break-in is taken into account:
Scenario 1. If discharging the batteries first, the first 10 hours of the 16 hours would be the "normal" charge that gives the battery to its full capacity, and so there will be 6 hours left for the "superfluous" charge (i.e., the continued charging after the battery has been fed to its full capacity -- call it "superfluous", "redundant" or whatever, you know what I mean)
Scenario 2. However, if the battery is already fully charged when it is put into break-in, then it might take 1 hour to the top off the battery for the loss of charge during the storage, and the rest 15 hours will be "superfluous" charge.
Now you get what I'm talking about -- the time in the break-in where the battery was under "superfluous" charge may vary, depending on the initial charge it holds before it is put into break-in.
Therefore here is the question: How do you do the break-in if the time of "superfluous" charge is taken into consideration:
1. Discharge the battery and rest, before it undergoes break-in?
2. Fully charge the battery and rest, before putting it in for break-in?
3. Just put the battery as it is into the break-in -- the initial charge it has doesn't matter??
