If you do not have the menu option for selection temperature or USB, then it might not matter what you do to the hardware. I thought all of them had the option, and some needed a minor hardware mod to add the connection. Mine worked as delivered, no hardware mod needed.
Check the menu thoroughly, it’s sort-of buried in there. On mine it is in the “User Set” “Program ->” menu.
Hi,
I agree with what you said, i.e., not prompt ==> no go.
I think that been through the User Set=> Program a 1000 times already. There’s one setting that says “Safety Temp” “Temp Cut-off”, but according to the PDF manual I found it’s suppose to say “Temp Cutoff” “USB Enable”.
I don’t know why the one I have is different, unless they hid the “USB Enable” somewhere else?
BTW, off-topic: I thought that this was suppose to be able to automatic discharge/charge cycles? From what I can tell, it only does that for Nimh. But, I also read somewhere that that could also be used for Li-Ion?
Thanks,
Jim
You can use NiMH for discharge, but not for charge. You cannot use the cycling feature in lithium ion cells.
It sounds like your charger does not have the feature then. Bummer.
On a hobby charger, only the NiMh mode has the auto charge-discharge cycle, for it is beneficial to such cells (refresh/break-in) who have been unused or are used in very low-drain devices like wall clocks and remote controls. It is not available to Li-Ion because doing so will only hasten its demise, not even improve it. It you happen to see an increase (of decrease) of mah capacity after doing charge-discharge cycles, it’s only because it is almost statistically impossible for the same cell to have the same result each time.
Hi all, not quite a Turnighy but I have this charger:
The Pro-Peak Mercury EX from Ripmax heralds a new era in simple-to-use feature packed charger technology.
Main Features Include:
€¢ Delta Peak detection/Zero current voltage check
€¢ Fast charge/discharge: 1~25 Cell NiCad/NiMH packs
€¢ 2~12v Lead Acid batteries, 3.6~11.1v Lithium batteries
€¢ 100~5000mA fast charge current
€¢ 20 watt discharge rate
€¢ User definable memories for: battery pack type, number of cells, capacity, charger/discharge currents
€¢ 2 line LCD display
€¢ On line charge/discharge status check
€¢ Audible alarm function
€¢ Integral cooling fan
€¢ DC 12v input voltage
€¢ Reverse polarity protection
I am looking to charge Sanyo Eneloops. Do I have to charge them one at a time using this charger ?
If I want to charge multiple batteries at the same time, should I buy a dedicated charger like the Technoline BC700 ?
Hobby chargers can charge pack of NiMH, i.e. batteries that are the same and has the same charge state.
To charge a couple of loose batteries, you must charge one at a time or get another charger. It does not have to be a analyzing charger, you can use the hobby charger for that, one cell at a time.
Would something like this be suitable for charging/discharging AA Eneloop batteries ?

If so, serial or parallel ?
Yes, in series.
But as I wrote above the cells must be equal (in age, capacity, cycles, brand and charge).
To initialize a pack a slow charge is used.
Thanks HKJ.
How many mA would you class as a slow charge ?
That is define as C/10 or below. I.e. 200mA on a 2000mAh cell.
Thanks HKJ
