I have a BT-C3400 2.2 that is maybe 18 months old. It’s always been fine. Lately slot 2 always shows charging, and the slot is empty. The slot is always at 3.9V, and the current fluctuates between 43mAh to 65mAh. I’ve tried sliding the slider, and beating on it. Not sure what else to try. The other 3 slots work fine. I’m geeky enough to tear it apart and put it back together again, but not sure if that will help. Any ideas? If nothing else, should I just go buy another of the same, or is there a new “Dream Charger” out now? Thanks for any help.
I looked at it at first, and wanted to say short. But the voltage always being rock steady, and the current constantly fluctuating like that, made me just go WTF, that’s not a short. Especially when slapping the snot out of it doesn’t change it’s behavior at all. I should send it to Lygate as a new V5.0 unit for review
last charger i saw doing that had been subjected to a leaker.
a good clean up fixed it.a li-ion leak will cause this and worse.
i have an ultrafire 26650 light where a leaker soaked into the board.its toast.no amount of cleaning fixes this.it has a leakage path in the inner layers of the board to the micro.
edit.
fixed it.the leakage path was under the emitter.
do post back on the outcome of checking this charger.
I am curious the cause, i wonder if sending it to HKJ would yield information, or if he is interested in dissecting it.
the shipping would probably not be cheap though
i wasn’t paying attention and charged a cr123 in my lii-500 engineer. it vented started, heating up so i tossed the battery in the snow. now i’m getting the ghost signal in the bay i used to charge the battery. i’ve played around with it and it actually charges my batteries still but i don’t trust the bay. wondering if i should get rid of it altogether
See if you can disable the bay by taking it apart and un wiring that bay.
I have a BT-C3100 v 2.0 that was charging 2 batteries and I put a 3rd battery in slot 1 backwards and screwed up the processor so that the bay will only charge at 170-180 Mah so it is good for very small batteries and still terminates, it’s just worthless for big batteries.
The charger is supposed to have reverse polarity protection, but it appears that is only if the other bays are not active that are in sync with each other at the time.
I replaced the charger with version 2.2 but still have the old one for extra usage if needed.
The whole thing is going haywire now and it appears something leaked in there so I guess I’m looking for a new charger. The last bay in my opus bt-c3400 is fried and since its v2.1, only 3 bays work properly when 4 batteries are installed. Thinking of an xtar next since I haven’t broken one of those yet.
