What is the mAH rating of the cells? (AKA "C") Sorry, I forgot the H in the NiMH battery rating, so it should read 400 mAH. spec sheets for two manufacturers and Wikipedia say Trickle charge (no delta temp or delta V) at 0.1 times mAH, or less, is safe. (0.1 x C) If your charger really is...

A Li-Ion Battery that is called UltraFire.

Well, at least they are giving you some truth in its name.
Or maybe what to expect from them in the near future, from these batteries. :lol:

Hmmm............... I came across this on another site. https://preview.ibb.co/eOOYUR/20180127_204507.jpg The person said the gold plated fingers on the RAM stick were rubbing off. {Thou, too me it looks like they were burned off.} In any case this is troubling, because CPU's in general draw a lot o...

have you tried the gold plated ones ? not sure if the ones on the tv or other units, are gold plated or not..i hear that gold never corrodes. Yup, still have the issue.... Only it takes longer for the problem to occur. Another Example: The sockets on the TV\Monitor may not have Gold plated contacts...

You must be buying the cheap ones. I wish that was the case. :x I've tried $10 to $20 dollar shielded HDMI cables for computers, and even those will have the issue with the contacts in the plug & jacks. I have replaced DVI & the even older SVGA Cables. But only because the cable was damaged...

I would like to take the person who came up with this design aside and punch them out! :mad: I keep going back to peoples homes to fix the: TV/Monitors, DVD/Blu-Ray Player/Recorders, and Game systems that use the HDMI Plug\Connectors. Mostly I replace the Cable. I found that sometimes you can get th...

Yeah,

I kinda thought it was going to be a Battery/Voltage issue. :(

How about making a regulator circuit?
Get a LM317T and set it up for 3Vdc out, with a 9Vdc {9V Battery or 9V Walwart} Input.

Okay,

But be careful.

Most fresh {or recharged} 1.5V Batteries will read about 1.65V to 1.68V.
Thus, the highest voltage you use with the receiver unit shouldn't go over 3.5V.

Otherwise you could fry it. :(

Are both the sending and receiving units Battery operated? If so...... Try replacing the batteries with fresh ones. I've been seeing a lot of weird things with low voltage battery devices. Even though the battery will read good with a battery tester. If the actual voltage is just at, or a little bit...

UPDATE: After checking every parts supplier I could find, and even a friend who works for a local electronic parts warehouse. There wasn't a power jack of type and spec's I needed anywhere in the USA. Even the company that made the power jack wasn't carrying replacements. :? WHY??? Well..... It tur...
