Exactly!The thinking behind it is probably:
A lower charging current triggers a lower temperature rise at the end of charging and thus also a lower voltage drop (delta peak) of the battery.
If the delta peak value is set too high, it may not always be reached with a lower charging current (e.g. 0.3C). The charger then does not recognize that the battery is full and continues to charge.
Another thought is:
If the setting: 0.3C charging current and -0dV end-of-charge detection function reliably in order to reliably trigger the end-of-charge detection of the charger, that would be even gentler on the battery due to the lower heating of the battery.
The problem is just:
What usually works well with new batteries often no longer works with older batteries.
Edit: On the other hand, I am of the opinion that with the -0dV setting (if it works), even with somewhat higher charging currents of 0.5 - 0.7C, the heating of the battery remains even low.
The problem with -odV is, that the charger is often switched off much too early.
0dV is indeed the recommended method for charge termination of NiMH cells. Most chargers use -dV just because it's easier (cheaper) to implement, but it overcharges NiMH.That sounds like 0dV is the recommended universal setting.
As I said, if the batteries are in good, like-new condition, I'll be there.
The problem are older batteries. Even with high delta peak settings of 6mV and more, I had premature charging shutdowns with them. And often not just once during a charge.
For such cases I have not yet found a setting where the charger runs through with certainty until it is fully charged.
Even with my much more expensive RC charger, with which I can also set a reflex mode, old NiMh batteries sometimes switch off prematurely
Would anyone happen to know if this unit is currently available directly from any established / respected U.S.-based distributor from stock (and preferably not through JB's site - although not a hard requirement)?
If I got one, I'd also prefer to not use its provided data interface(s), although I would like to have the ability to alter some very basic parameters / settings directly using the provided interface 'buttons' (as one does with other chargers such as my Opus, etc.), so any insight into what one can specifically alter using that method would also be helpful to knowl
- It seems you might have bought the last one they had.
The fact that you are able to do most (if not all) the basic 'required' setup using the front panel also gives me some assurance that I'd be able to do likewise, at least for the most part. I may not need to change much from default values in most cases, but it's good to know that it's possible, and as I understand it, most other more detailed parameters can be changed / set using the data interface(s) if eventually desired.
The fact that you did a FW update is probably a +/- thing.
no, i bought mine over a year ago.
you could try messaging the seller and asking when they might restock.
again, there is no need to use the usb or bluetooth interfaces. every setting is exposed on the device UI. the device is fully featured, standalone device without using usb or bluetooth, and in fact i do not use them for a couple of reasons:
i'd only consider using the usb interface... and that's only if i wanted a fancy charging graph if i were posting a review of a cell online or something. i think it can do fancy graphs? idk
- i've heard reports of bugs (profile settings not applying correctly)
- it adds unnecessary complexity to the apparatus
some of the updates may be useful. your device will probably already have the newest or second newest fw version. the second newest fw is good enough. i just updated mine for fun.
for info about the newest update, read starting from here
No MAC version listed for 1.17. Wonder what this “new” firmware does? Don’t see any change log…. media access control?? yeah, where's the release notes?www.candlepowerforums.com
that's just a few posts above where we're talking.
i'm on the newest fw and have no problems with it. if you choose to update the fw, you should do so as a first step because it will erase all your settings and profiles. configure your device after updating.
