B6ac Help me please!

So i just bought the Imax b6ac charger and dont really have a clue how to use it and what values to enter can you help me out please? :slight_smile:

I just charged an 18650 on 2.0 amp… is that correct?

Newbie here also, but I think that the answer depends on the capacity of the battery. I think that the capacity is called “1C”, so if your battery has a capacity of 1000 mAh (milliamp-hours), then “1C” is 1000.

According to this:

http://www.microchip.com/stellent/groups/designcenter_sg/documents/market_communication/en028061.pdf

so that would be .2 amps to 1 amp (=1000 milliamps), so probably charging at 2 amps might be a bit much in this case.

I think that if your battery had capacity of 2000 mAh, then 1C = 2 amps, so then you’re ok charging at 2 amps.

As I said, I’m a newbie, so take that with a LARGE grain of salt.

P.S. That same article also says “

.

P.P.S. I’ve been using 1.0 amps for all batteries except for 10440 batteries, and using 0.5 amps for 10440 batteries. Come to think of it that might be too high for the 10440 batteries, since they’re capacity is probably not more than 500 mAh

P.P.P.S. A question for others: When they say “1C” ~ capacity, which capacity do they mean? Do they mean the advertised capacity? Or, the actual capacity? If it’s the latter, then how can you figure the 1C rate, i.e., how do you know the actual capacity, unless you do a discharge test for every battery?

My B6 charger set to 1A for 18650.

Probably not. For 18650 is it safest to use 1A.

Some 18650 batteries can be charged with higher current, but the very common 2900 and 3100 mAh is both rated for a charge current below 1A.

Thanks guys!

BTW, in case you ever charge 10440s (AAA-size lithium), I think that you’re suppose to use even less current, like 0.5A, I think.
