Thanks, now I’ll be able to read up before my BT-C3400 arrives (by Saturday).
Ended up ordering the BT-3100 with the European ac/dc power adapter (KYT120300BV), come with a Euro/US add-on adapter, which I guess I lost.
Where in the USA can I order a replacement AC/DC power unit, for my BT-3100?
(I would rather just get the whole power unit, and not have to use the euro/US adapter)
…unless the 3400 has some other code issues not present in the 3100.
This unit requires =significant= patience. Even at higher rates, it can take 3 hours to discharge and 4 hours to charge for todays 3,xxx mah cells. The best you can do is 2 amp charge and 1 amp discharge. Do the math
Ran across this thread on a Google search and wondering if I might be able to use the BT-C3400 Charger Analyzer to test the mAh capacity of my cell phone’s Li-ion Batteries? Since cell batteries are of course square and will not load traditionally into the BT-C3400… my plan is to open the charger/analyzer and affix jumper leads to the /- terminal and then run/secure those leads to the/- terminals of my cell phone battery. Any thoughts on this would be greatly appreciated… also interested in any leads on any other chargers/mAh analyzers which may be more suitable for testing mAh capacity on cell phone batteries(?) Incidentally, I find it rather odd that someone has not designed a (economical) charger/analyzer to test all the square cell phone batteries on the market these days!?
As to your next concern about a dedicated charger/analyzer for cellphone batteries, perhaps IMO, manufacturers are afraid it won’t be a commercial success for the sole reason that only few people buy extra batts for their phones.
Great info (thanks) already planned on gutting my universal fit mobile phone charger, now looks like the bigger challenge is finding a relatively inexpensive charger/analyzer that can be set to charge low enough for a accurate mAh reading re my Samsung 3.8v 2600 mAh li-io’s. There are a few bare bones li-ion charge analyzers on ebay (price is sweet) but the Asian/English instructions look a bit challenging and unfortunately most listings aren’t providing a min/max charge rate spec, nor are they confirming if their units display analyzed capacity in mAh or %(?) Anyone know the min charge rate I should be shooting for in a charge analyzer to get a good mAh read for mobile batts… 50-60-100ma? Anyone by chance ever seen a c/a on ebay that even comes close to such low charge/test currents? Should I just go with the BT-C3400 and call it a day?
btw… had no intentions of high jacking this thread. If need be I can copy, paste and repost in the other thread if need be(?)

The charger has a standard 12V DC connector. You can just buy a 12V AC adapter with the desired line cord/plug as long as it can output at least 3 amps at 12V. Because of the issues on the V2.0, I actually use a 6 amp AC adapter, and that solves the problems that v2.1 fixed. The problem is that the charger basically uses PWM to charge, so during the charge cycle the peak current is a lot more than the average current, and the original 3 amp supply didn’t have enough output to provide the peak current required. A larger power supply solves that problem.
Hmmm? OK, but do you have any specs from an operation manual to show that the 3100 works with 'C' batteries? All the specs I have read on the 3100 do not list 'C' batteries as being compatible, but they list 'C' batteries in the specs of the 3400 as being compatible.
Nevertheless, do you have a pic showing real capacity with mAh with the exact same batteries in the test mode?
I think the question here is that if the 3100 was apparently not designed to work with 'C' batteries but does appear to be working with 'C' batteries, is it really working properly with 'C' batteries?
I'd love to see a pic with those same exact 2000 mAh batteries showing the mAh real capacity in the test mode. This would be very convincing that the 3100 works properly with 'C' batteries even though it wasn't apparently designed to work with 'C' batteries.
By the way, have you been able to get it to test for mAh real capacity with 'D' batteries?
