I recently replaced an older Titan with a new LR model, and I have a Titan battery backup installed in this location.
Unfortunately, the battery pack does not power the new Titan when line power is removed… The battery has steady blue LED when powered, and it (very) slowly flashes blue indicating that it’s discharging when unplugged, but it then doesn’t pass any juice to the Titan (the Titan becomes completely unresponsive and has no LED activity).
All connections are triple-checked tight & correct. All other aspects of the Titan are working great when it’s line-powered – it then properly reports battery (charge), batteryStatus, and powerSource as expected (100, maintaining, mains respectively)
I confess I didn’t confirm if all of that was working fine before swapping out the Titans, but I know it’s all worked correctly in the past (with the old Titan) when I’ve pulled power on that circuit.
Is it possible that my battery pack is somehow already dead, or could it be something else unique to the (new) 700LR Titan?
We will try to replicate this issue on our end as well.
We do not believe that there is an issue with your battery pack as well. Most likely the issue is with the installation sequence between the new ZAC36LR and ZAC92.
If it’s helpful, I’m using Jeff Page’s driver on a Hubitat C8 Pro (everything updated on latest versions).
This Titan is paired LR.
Although I did the initial pairing with the battery connected, I also did an exclude / re-include as an additional troubleshooting step. In both the original inclusion and the re-inclusion, the battery was identified as hoped/expected.
So except for the fact that the battery does not actually pass any power when line power is removed, everything else is working great!
I got the battery in early June 2023 (order # 99608).
Thanks for your willingness to look into this - I appreciate it!
By any chance do you have a digital multimeter and can check the battery voltage itself? On the battery backup, there is one screw itself and if you unscrew it, you can pull out the battery itself and check the voltage - DC. It should be 3.7-3.8V when fully charged.
Got the tester out, opened up the case, and battery seems to be in great shape – it looks brand new and it reads 3.86v. Everything appears to be in good shape inside the case – zero leakage or anything like that.
So I popped battery back in, and the pack started doing a very slow blue LED blink (1 blue blink ~9-10 seconds).
Wired it back in the Titan again, and same results – it passes line power through fine, but when the power plug is pulled, the Titan goes dark and the pack’s LED starts doing that slow blue blink (1 every 9-10 sec).
Thanks again for your help & thoughts!
Edit to add…
Just checked device states in Hubitat, and it’s now back to this… Nothing changes when the plug is pulled since the Titan then becomes unpowered.
I’m at work right now, but I’ll get the form completed this afternoon when I get back home, and I’ll be sure to reference this thread in the request.
I really appreciate this - thank you again!
Edit to add – replacement is now enroute I will quick-turn my current unit back to you folks ASAP once I get the replacement in and confirmed working. Thank you again for your help on this!
I got the replacement battery swapped in, and it’s working great – when line power is removed, it transitions immediately to battery. The corresponding battery-related beeps and LEDs are all as they should be when the power on/off transitions happen.
I have the old battery packed up, and I’ll get it in the mail back to you folks tomorrow.
Thank you again for your help getting this resolved - it’s much appreciated!
I’m back again with this same problem (I must be cursed! )… It’s a long story, but I recently moved my all my ZW devices from Hubitat to Home Assistant (HA).
This same battery issue resurfaced when I included my Titan and its battery pack to HA… Everything went smooth-as-silk with the Titan’s HA inclusion (all entities & attributes were created as expected, to include all the power/battery stuff).
But when I disconnected mains power as a quick test, the battery wouldn’t feed the Titan – the Titan would instead just go dark/offline.
That battery pack (and battery) is all in flawless condition (battery looks brand-new and reads >3.8v), and it was all working fine back on on Hubitat.
I’m very admittedly an HA noob, but I am confident I tried every troubleshooting sequence and re-attack that Google/AI offered (to include numerous factory reset + exclude/re-include attempts), but I could NOT get that darn battery to pass power when off mains.
I ordered a new battery pack this week from y’all and I just installed it… And perfection – it works like a champ – it passes power through just fine when off mains.
So I have 2 questions please…
Is there some kind of “reset” process the battery pack itself needs if it’s A.) moved from one Titan to a new one, or B.) if its same Titan is moved to a different controller? Those are the 2 situations that have caused this issue for me so far…
This is admittedly unrelated, but for maintaining the battery’s long-term health, would you folks recommend occasionally running the Titan on battery in order to exercise it a bit? I’m thinking just a couple hours a day a few times a week – is that crazy talk?
Nuts, a third question here… Is the battery itself lithium? Since I unfortunately cannot get this (old) pack to work with either of my Titans anymore, I’d at least like to ensure its battery gets properly recycled.
Hey Chris, sorry to hear about the issues you encountered. Love the move to HA, that’ll be fun
No, there is no reset for the battery pack itself, only the TItan
We can check with our factory if this would be recommended.
Yes, it’s a lithium battery.
Before disposal, Bartek has a quick test for you to run if you’re open to it. Remove the new battery itself from the pack and put it into the old battery pack (removing the old battery first) and see if exhibits the same behavior. If yes, that means that battery itself is good AND the battery pack itself is broken.
This would confirm where the issue is, and if that is the case, then you would have 1 battery pack (case) and 2x batteries for replacement
I will quick-turn my current unit back to you folks ASAP once I get the replacement in and confirmed working. Thank you again for your help on this!
