why batteries go down on maha

[stormtracker78]

hello all on my very last thread I had asked if I should discharge my new 8 pack maha batteries before I use them with the break in cycle which I did. the batteries started from 2505 all the way to 2584 after their 1st completed break in I noticed however there not lasting .after the 1st break I took 3 that were 2558(1.43vlt) 2554(1.42vlt) 2584(1.43vlt)I used them in my scanner but they didn't last that long so I used the break in cycle once more and got this 2516 (1.42)2526(1.42) 2535(1.42) how come they went down so quick in mah .they are in the same order 2558 goes to 2516? 2554 to2516? 2584 to 2535?? the loss 0f a little vlt too does anyone now why or what I can do there brand new used once and the other I have in my scanners are going down fast to ?

the batteries started from 2505 all the way to 2584 after their 1st completed break in I noticed however there not lasting .

after the 1st break I took 3 that were 2558(1.43vlt) 2554(1.42vlt) 2584(1.43vlt)

I used them in my scanner but they didn't last that long so I used the break in cycle once more and got this 2516 (1.42)2526(1.42) 2535(1.42)

how come they went down so quick in mah .they are in the same order 2558 goes to 2516? 2554 to2516? 2584 to 2535?? the loss 0f a little vlt too does anyone now why or what I can do there brand new used once and the other I have in my scanners are going down fast to ?

The numbers are not that different, statistically. What is the accuracy of your measurement device?

What is the reproducibility of the drainage cycle?

As said the difference is very small and two of the cells you started with you had at 1.43V while they're at 1.42V which will also make a small decrease. It can be a variation in the charger as well which has gone unnamed as is the model. If you were loosing several 100 mA then there may be cause for concern. Not this however.
