I’ve discovered a few funky things about charging my rechargeable ReSound LiNX Quattro 9 61’s that anyone else with the HA’s might find useful to know or might find behaves differently and want to contrast their experience.
First of all, the behavior of the bank of 5 charging LED’s for the HA itself, represented in the Smart 3D app and on the front of the charger case for charging the HA’s. Discharging the number of lit green circles seems to represent the state of charge you’d expect. 5 circles lit, fully charged. 2 circles of 5 lit, 40% charged, etc. But in charging ReSound seems to have switched the logic. You start out at 2 of 5 circles lit, you charge to just over 3 LED circles lit and the 4th has just started to flash. So you think, OK, based on the way things went down during discharge, you’ve charged to just over 3 circles lit (>60% lit) and you’re working on the 4th charge state (80%) being reached (it’s flashing) but you’re not there yet, because otherwise it would be solidly lit. (This is following charging of each HA in the Smart 3D app). But what happens at this state when you remove the HA’s from the charger and look in the app, you see, according to my interpretation of how the app display % charge when not charging, that you’ve actually charged the HA’s to >80% charge. Apparently, going up in charge, an LED up the charging scale starts flashing ONLY WHEN YOU’VE PAST THAT DEGREE OF CHARGING. I’d rather have a particular LED in the hierarchy only light and stay solidly lit when you’ve passed that level of charge and have the next level light start flashing to indicate that you’re just beginning to work on that level.
The other funky thing is the bank of three LED’s displaying the state of the charging case Li-ion battery that serves as a power pack to charge the rechargeable HA’s. I got the charger case from the audi on Wednesday, 10/24/18, fully charged. The charger case supposedly holds 3 complete charges for both HA’s. Since Wed. at 30 hours of use per full charge, I estimate I have done the equivalent of fully charge my HA’s 1.5x to 2x, yet the LED’s on the charger case still show all 3 LED’s fully lit when I insert or remove the HA’s Theoretically, at least one of the 3 LED’s should have gone out by now as I should have used at least one full charge from the case (I haven’t charged anything on AC yet myself).
So I’m a sample of one. If you just charge your HA’s every night, maybe none of this makes any difference because you’ll charge both your charger case and the HA’s fully but if you need a quick charge and want to know where you’ve actually charged to as the HA’s are being recharged in their case, knowing about the funky behavior that I describe about the 5 HA LED charge indicators might make a difference. Also, if you’re counting on the 3 charger case LED’s to accurately reflect the charger state of charge when used as a power pack, you might go out the door with the charger case with 3 circles lit thinking it’s full of reserve charging capacity when it’s not if you haven’t fully charged both HA’s and the charger case overnight.
