Just an update on the new batteries, everything is working well and I got at least 7 hours of playback on Friday using my DT1990 pro headphone I didn't even get a red light. This is great and I really didn't realise how poor the old batteries had got at only 4-5 hours usage before the red light appeared.
I've been testing one of the old cells and this is what I found:
1st discharge 787mah to 3.4V - It probably wasn't fully charged
1st charge 1263mah to 4.1V
2nd discharge 1025mah to 3.4V
So yes quite poor and nowhere near the rated 3350mah capacity, it was also noted that the voltage dropped off very quickly when discharged, possibly a sign of high IR. If this cell had been in a laptop pack it would have been discarded a while ago I suspect.
The loss in capacity had been very gradual, so its not really noticeable. I would recommend this fix for anyone getting < 4-5h use per charge and knows one end of a screwdriver from the other.
I didn't test the new cells before I installed them, I wish I had now but its not really worth opening it up again just to test the new batteries.
I'm not sure if Chord would replace the batteries for free if still in warranty, but I did contact Chord and was told that 5h use is within acceptable limits and they would not be replaced. My Hugo2 is probably out of battery warranty anyway as I purchased it in 2017.
Happy listening everyone.
Can I ask please, did you run your Hugo 2 in a case? I found doing that, the Hugo 2 got very hot which is bad for lithium batteries. I did lose some battery life doing the time I ran Hugo 2 in a case. Not too much to make me worried or upset. Still can't be sure it was that which caused it, but you know.
Also please the new batteries you got, do they have sticky pads with them to secure then inside the Hugo 2? Need to know just in case I ever need to get battieries, thank you.
