Teric owners, have you required repair or replacement service?

[O-ring]

Mine are dramatically different as well. Last few weeks of data:

Teric 1                                Teric 2
86% on 5/13                            38% on 5/13
70% on 5/20                            36% on 5/20
54% on 5/27                            36% on 5/27
46% on 6/3                             34% on 6/3

Hi @O-ring

Were they charged to 100% at the same time? When was that?

Yup.. Teric 1 gets about 7 charges to every 1 charge for Teric 2. In storage Teric 1 will average about 1 charge every 2 mos or so whereas Teric 2 could probably go almost a year in storage without needing a charge.

Teric 1 was fully charged on 5/6 and here's the drain history since then:

<charging Teric 1 - 5/6>
86% on 5/13
70% on 5/20
54% on 5/27
46% on 6/3

Well definitely need to have my "Primary" Teric repaired. I charged both to full Sunday 06/09/24. Because I broke my leg last week I couldn't dive, but when I pulled it out today 06/19/24 to dive, "Primary" was at 64% while the "Backup" was still at 100%. Both sat unused.

Broke leg last week. Going to dive today.

Hardcore!!

Prosthetic leg broke, the pylon collapsed so it like an inch too short. At Ginnie in the middle of setup too. Didn't want to continue as walking on a leg too short injures your back, hips, and knees. So I packed everything up and went home repairing it with a part from an older leg.

Ah. I never knew! Rock on, man!

I received my Teric back from Narked@90 after a routine service. After 51 days it’s on 86%. I’m happy with that.

Ps Impeccable service from Narked@90 btw.

Battery saga...

I received my most recent Teric in January and decided to watch the battery life carefully. I charged it to 100% and went diving at the end of January/beginning of Feb. I charged it after the trip and then did not have a chance to dive for quite a while. I charged it to 100% and went diving in May. I charged it after the trip. I recently went out on the Nautilus Explorer, charging it as needed during the trip and again at the end. The battery consumption in storage has increased from 0.6 to 4.8% per day over this time. During the third period, it went down to 98% at 1 day and 92% at 2 days.

Interestingly, the battery consumption during dives has not changed, remaining 7-8% per dive (all around an hour each). There are other variables around this measurement, simply decided to follow it.

I have not shared this with Dive-Tronix or Shearwater yet, will continue to follow for now.

@Scubada: That is disappointing.

But, I do have to wonder if charging it to full after a trip and then leaving it sitting has contributed to the degradation. I have read many times that Li-ion batteries prefer to be stored at a state of charge of 80% or less.

I have been resisting the temptation to charge mine after a trip. I just let them be and only charge them when I'm getting ready to go dive next. Mine have not yet sat idle long enough to need a top-up charge just from self-discharge while stored. Not since the last battery replacements in January-ish.

Also, I have only been charging mine by plugging the USB cable into a battery bank instead of a wall wart. The battery bank turns itself off after a period of inactivity. So, once the Teric hits full charge and the Shearwater charger stops, the battery bank will turn off before there is any chance of the Teric charge dropping enough to kick off a new round of charging.

As you know, I lost one Teric just over a week ago, but the other one is still holding a charge well.
