Teric owners, have you required repair or replacement service?

[scubadada]

I received my repaired Teric #8 from Dive-Tronix yesterday after it underwent battery replacement following 1 year of use. Each time I get back a replacement or repaired Teric, I hope that one will be perfect. I hope that again now. The 2-year clock has been restarted.

My repaired Teric #8 has now been through 2 standby cycles and 2 short dive trips. The battery performance has been excellent, very little battery consumption in standby and good performance on dives. I now have another short standby period followed by an intense two week dive trip to Bonaire. I hope this continues...

My poor Teric (twice serviced for battery issues) loses 50% power a week in standby. Fortunately i dive it almost ever week and recharge it often. It needs to go in again, probably when i send it my Petrel 3 for the recall.

I’m new to scubaboard and looking to purchase a dive computer. The Teric is on my shortlist so this thread is of interest. I was hoping to find a concise narrative describing how Shearwater finally solved the Teric-problem (whatever that might mean) but that’s not what I’m seeing. It looks like there are ongoing problems even for those who bought their Terics in 2024 and 2025..? I suppose this could be a sampling issue—happy customers are perhaps less likely to visit such threads. But still, it’s concerning.

Hi @Pelagics

I assume you are referencing the problem with deteriorating, short battery life, but you may also mean the fragile air integration antenna.

As far as I know, Shearwater has not directly addressed either of these issues in an information release. I would be glad to be corrected if this is inaccurate.

This information is included in Teric FAQ, I have had several Terics replaced or repaired under warranty since I purchased one in 2019:

The typical battery life is 5 years.

The battery can be replaced at authorized service centers.

The turn around time for replacement is 5 business days after receipt of payment, excluding shipping time. The battery replacement includes inspection, functional testing and pressure testing.

If the battery is not meeting performance specifications within the 2-year warranty period it will be replaced free of charge. Variations to battery lifespan can be expected due to operating at extremes of the rated specification, such as high environmental temperatures or repeatedly fully discharging the battery.

Well an update, I think I finally got a good battery in one of my Terics

Teric B received from SRI on 09/19/23 with original battery 80%
Teric P received from SRI 09/25/23, battery replaced 08/28/24 56%

Both were charged about two weeks ago, and did two dives with downloads.

I acquired one again, prices have really dropped since tern and peregrine tx came out hope it is a good one.

I have not posted to this thread for a while. As some of you know, I have had my share of problems with my Terics since I first purchased one in May of 2019. This includes four battery failures replaced or repaired within the 2 year warranty period. The service from Richard and Michele Morton at Dive-Tronix has been absolutely fabulous the entire time.

My 8th Teric battery was failing after 7 or 8 months but I did not have it repaired until the end of a year. I simply charged it whenever it was required. This battery followed the usual progression of holding 100% charge for less time and then increasing discharge in the 1st 48 hours and daily. The Shearwater specification, at least previously, was <8% discharge in the first 48 hours. It is interesting that the battery consumption per dive never changed significantly. I dived this Teric for 94 dives in 7 trips.

I sent off my 8th Teric at the end of January 2025. It was repaired and returned to me at the beginning of February. The battery performance was flawless for the first six months, holding 100% charge for a long period and having very little discharge per day. I have done 64 dives in 4 trips so far. In the current standby period, the 100% charge period may have decreased and the daily discharge appears to have increased. The battery is still well within specs, time will tell.

Does anyone else track standby battery discharge rates for their Teric(s)? They would be interesting to see.

I track them but haven't posted my results for a while. I just noticed that starting in May my "good Teric" started draining even faster than my "bad Teric" so I kind of think this is just the inevitable fate of all Terics. The good Teric used to only drop 2% or so a week in storage. Now I am seeing good Teric drops of between 2% and 12% a week and bad Teric drops of between 4% and 16% a week.

I charged them both a week ago and today's battery levels are listed below.

Date	Good Teric	Bad Teric
7/28	100%	100%
8/4	88%	90%

Hi @O-ring

I believe that you may be correct and that this is the inevitable fate for Terics.

In all of the posts to this thread, I don't think I have heard anyone reporting that their Teric battery is performing as well after a couple years of use as it was when new. It would be interesting to hear from those folks who have reported that they have never required repair or replacement.

Yes...I wonder where all those folks are hiding.. I suspect some percentage of the owner population just doesn't pay attention to it, digs it out of a box when they want to go diving, charges it and then it goes back in the box when they get home. As long as it doesn't die whilst underwater life is good.. The other end of the spectrum are the data driven weirdos like us that obsessively track it and wonder what in the world is going on inside its tiny little Teric brain that would cause it to drop 2% one week and 16% the next when stored in an identical manner.

I suspect this is kind of like living with an exotic car/bike. You have to decide at some point if the fiddliness bothers you and then, if it does, does it bother you so much that you are sending it in every couple years for repairs. If it gets to that point does it get labeled an obsession and you are better off just getting something else so you can stop the madness and perma delete your battery level spreadsheet.
