4 more awaiting their turn on the Maha...
They are made in Taiwan. Here is a shot and some comparisons to a Duraloop and a ROV Platinum
More testing to come!
How about some testing at 8-9 AMP draw vs. Eneloop?
I am running 4xEneloop with SST-90 & it pulls 8.3Amp,
can these cells perform better at that Amp?
Anyone tested these for performance in the cold?
I thought my 2100mah ones were awesome until I took them out in 35F weather.
The performance of NiMH cells decreases with decreasing temperature because the conductivity of the electrolyte decreases. Essentially, the internal resistance of the cell increases as temperature decreases. Since all NiMH cells use essentially the same electrolyte, you should expect a similar decrease in the performance of the Imedion 2400 at low temperature that you see in the 2100 mAh version.
That being said, if you need better performance at low temperature, then try a high rate NiMH cell like the Elite 1700. The performance of that cell will still decrease as the temperature decreases, but since it starts out with a very low internal resistance at room temperature, it may significantly outperform the Imedion or Eneloop cells at very low temperatures.
Yes, I had that happen with one oif my MH-C9000s. The fix was to take it (The charger) apart and add some solder blobs to the chargers' positive contacts.Anyone has problems with the positive terminal/button top not making contact? I have some old Imedion (2100mAh) and they do have a problem with some devices. In particular with my PowerEx/Maha MH-C401FS you have to pull the battery out slightly for it to make contact in the far left (or is it right?) terminal. I think I read someone with a similar complaint
I've just received a batch of 16 o these new 2400mAh Imedions. Initial capacity goes very close to 1850mAh in the two sets I've discharged in order to run a break-in cycle.
Is this initial capacity normal? I won't have capacity numbers for a few days until the break-in finishes...
Why is everybody so positive about the capacity on these cells? I have yet to see one that actually reaches the claimed capacity, let alone go a bit over so it will keep withing spec after a bit of wear..... I just hate products that don't live up to the two or three specs they have.
However, am i right that these cells have roughly the same price-tag as the eneloops? In that case the 5~10% increase in capacity is just a nice little bonus (if they hold up after use like my eneloops that is)
