There have been many changes since HKJ's review (FW1.02?), take your pick:

Hi Kreisl, Thank you for the above links, they answered a lot for me, as I've been absent from this forum for over a year.
I was an early 2016 buyer and did the fan mod, took the system apart and rounded the slider edges and used DeOxIT Gold. Got to know the insides pretty well. Then I went happily using this for my 18650s for night bike rides and charging all my AAAs and AAs (sometimes testing them, throwing out the bad ones). Love the charger. Switched all my NiMH to Eneloops. Great charger! Learned a lot from people here, you, and HKJ. The only thing I didn't do was firmware update as I don't have a PC (mac).
Alas, 2 spring retainer posts from that v1.0 plastic broke spontaneously over a month, knocking out 2 bays and that was inconvenient to say the least. Instead of hooking the spring to the holes in the PCB, I epoxied the posts and they are pretty strong now. Also had one screw retainer break and epoxied that too with success.
Problem is, on putting it together, I had some DeOxIT that might have gotten onto the PCB, and now it reads the batteries ok, but when I go to charge, Bay 2 says there's a Short Circuit and then the system reboots. I opened it up and used pure alcohol to clean the PCB and connections, and no joy. Bay 2 problem and reboot. Bay 2 says Short Circuit, and system reboots right after. This only happens when charging is initiated - reading the batteries goes aok for all the bays. (also, the first time this happened, I got a error statement, but it flashed away before could write it down and now I don't have the error statement anymore but it cycles on reboot as noted).
I'm worried there's been some internal damage - Does anyone know of this behavior and cause? Is this a known issue that there's a known fix for?
If there's so easy solution:
1. Do you think the manuf will sell me a new one at a discount because it was v1.0 problems that caused this to break down?
2. How do I get a hold of the manuf? Through Gearbest where I bought it?
2. Who has the latest versions (that is, are the latest updates/firmware now shipping from Amazon or Gearbest?) Who is the best seller these days?
I love the charger, and I can borrow my friend's cheap charger for a few weeks until I get a new one. I'd hate to have to abort and buy a $30 you know what ... If anyone has advice along the lines of the above, I would appreciate it very much. I'm sorry to have disappeared - been working hard on a turnaround and just got burned in biz, so back to my hobby things to cheer me up. Through it all, this thread is one of the coolest on the web for a guy who is trying to age gracefully and enjoy using his hands on stuff once in awhile. This and the auto forums ...
