For the record, I never post until I have read the entire thread, as I did here. I was fully aware of the subject of the thread. Again, since apparently you still don't get it, I was merely reporting that my experience showed the Eneloop were the most reliable. Frankly, I don't give the north end of a southbound rat whether you agree or not. You seem to be the one that has problems with other people's opinions.

Btw, your little tests only address how long the batteries you are testing will run in the JBL. It will take several months, if not years, to determine how long the batteries will continue to be usable before they fail. How long the batteries I used lasted was what I was addressing. I would much rather have a reliable battery than a high capacity battery.

While I haven't the time or money to waste on doing a formal study (I have more important things to do), I have had experience with both the conventional NiMH and the newer "precharged" NiMH and have had much better luck with them, especially the Eneloops. And that is what I reported.

This is jj2me's post in case you missed it:

LSD (like Eneloops) vs. regular NiMH - "few weeks of storage" crossover point

--------------------------------------------------------------------------------

The crossover point where a typical LSD (low self-discharge) is longer-lasting than a typical traditional NiMH (with its higher capacity), is given by this heuristic on Wikipedia:


Quote:
However, after only a few weeks of storage, the retained capacity of low-self-discharge batteries often exceeds that of traditional NiMH batteries of higher capacity.

which references this website that tested 4 AA Eneloops vs. 4AA "well respected brand" traditional NiMHs.

I over-analyzed from this tiny sample by doing the following crossover point calculations using the charts in that reference (white charts for Eneloops, scroll down for pink charts for traditionals):
Nominal capacity (Eneloops | Traditional): 2000 mAh | 2500 mAh.
Measured capacity after 5 and 4 charge/discharge cycles at 1.2A (Eneloops | Traditional)): 1848 mAh | 2172 mAh
Charge retention (Eneloops (mAh) | Traditional (mAh)):
Day: 99.8% (1844 mAh ) | 99% (2150 mAh)
Week: 98.7% (1824 mAh) | 93.3% (2026 mAh)
Month: 94.3% (1743 mAh) | 73.8% (1602 mAh)

Assuming approximately a straight line storage discharge curve (taking some liberty when looking at this site's non-linear NiMH Battery Retention Curve), we come out to approximately three weeks of storage, whereupon a 2000 mAH LSD NiMH retains more capacity than a 2500 mAh Traditional NiMH.
