Bought three 40Ts from reputable seller for $4/ea. Capacities measured 4230, 3850 and 3750. IR measurements, for what they are worth, were 18 to 25 mohm.
Should these be matched better to use in a 3 cell light like the TS32? Maybe grade B cells or, heaven forbid, impostors?
Or is inherent inaccuracy of chargers the likely culprit, and maybe these are really closer than measured?
I bought them as a dedicated spare set for TS32.
Not even close.
I wouldn’t use them. Can they be returned?
I’d run a few more cycles through them and check again. I don’t really trust these chargers for capacity testing. I have run the same cell through those cycles 5 times in row and come up with numbers totally off the wall.
I suppose but maybe I will just use them in single cell lights. I was suspicious of low price but from a seller generally well thought of on this forum. I don’t mind if grade B or even fakes so long as they would perform acceptably for the price.
Yes I was wondering about the charger accuracy too. I guess I will try a couple more times (days) and see what happens. It is a DLYFULL T5 Test Charger.
If all cells were fully charged at the same current and discharged at the same current 2-3 times, then the cells are completely garbage for use in any series battery packs.
Aren’t batteries in the TS32 running in parallel? If so why would mismatched batteries be an issue as long as they were at or about the same voltage when inserted into the light? Once connected they would equalize to the same voltage and would remain so when the light is used or being charged.
I assume you`ve read the review by HKJ before buying this charger.
It is a fairly good charger. And eh ……, who’s perfect?
The TS 32 is loaded with 3 cells that are operating parallel, meaning that basically they all are doing their thing without too much interference by the other cells. Which lowers the need for a perfect matched set of cells a bit.
HKJ wrote in his review: “The four capacity readouts also shows that the slots do not match, in all my tests slot #1 & #4 shows higher capacity than slot #2 & #3.
So if the capacities you measured are all from the same session, at the same time, theoretically one of them should be ”off”. I admit it is a bit tedious, but I always check the capacity of my cells in the same slot. Thus avoiding differences in accuracy between slots.
I’m with toddcshoe, you don’t have enough reliable information. Same cell, same charger will net different results in both cycle capacity and IR.
Charge, then do a discharge only from the same bay for all, assuming you can do that.
If, as has been stated cells are parallel, doesn’t matter much anyway. Could be fake @ $4. Use ’em like you stole them. 
OK good things to consider. And Henk4U2, yes, slot 1 was the “winner” coming in at the 4200. Both 2 and 3 were similar coming in around 3800, and I was not using 4 at the time. I did read the HKJ review when I bought the charger but did not refresh myself on his results and observations so thanks for the reminder.
IMHO, even with the reputable suppliers, fakes (likely unintentional) or Gr. B cells are a relatively common occurrence. I am a bit (maybe too) paranoid in that regard.
I wouldn’t call that being paranoid, just cautious. Better safe than sorry.
