[Ni Battery 4 Serial Numberl

Batteries are an indispensable energy source. They are also a key technology in the transition to climate neutrality, and to a more circular economy. Global demand for batteries is increasing rapidly and is set to increase 14 times by 2030. The EU could account for 17% of that demand.
The European Parliament and the Council adopted the new Batteries Regulation on 12 July 2023. This will minimise the environmental impact of this exponential growth in light of new socioeconomic conditions, technological developments, markets, and battery usages.
Using the information at this page: My UPSes count their internal battery as an external one in contradiction to the online help, the English language and common sense. IMHO This should be considered a bug and fixed. I digress.
Brian, are these the original batteries of the UPS or did you replace them recently or a few years ago? We had similar problems and usually the setting on the General for battery packs are calculated values. We also suspected that the batteries are of age and needed to replace them as well as check the connector from the extended frame is connecting correctly to the main unit.
Since the runtime estimate you see is just an estimate (or prediction as the above says), I do not believe having this count set incorrectly is a problem. The only time I think it may be is if you have software settings that trigger a shutdown based on runtime. But even then, I was under the impression the time would update as it goes but that may not be the case on every single model listed above.
Since it sounds like you have a Network Management Card, do you see anything in the log files? You can share them here ( ) by following these instructions. I am not sure what model of management card it is but a .tar is preferable or config.ini, data.txt, and event.txt with a general time frame to check for when this occurred.
The only time I think this value could get reset is if you reset the UPS to defaults (an option through the management card). I have never seen it reset on its own. I am thinking at this time this value is set on the UPS itself and not the NMC but I'd have to double check to be absolutely sure because I know you can set it via other means.
I think if you do a calibration first then change this value, the NMC is just updating it by a standard amount, knowing the model and how much runtime an extra battery pack provides. How old are the UPS batteries in the UPS and the pack? I would not do many calibrations, especially if the batteries are not too new. A power outage ultimately is supported to accomplish this to update that runtime estimate. If you do do another calibration, I'd ideally do it manually if at all possible (instead of issuing the calibration via the NMC). Instructions and general considerations for runtime calibrations are here:
I did have a system hooked to the serial port in addition to the NMC. This is apparently unsupported. Once I updated the firmware of the NMC it would refuse to work until I unplugged the serial cable.
I can ask my Unix admin to check his logs and see if the Unix box told the ups to shutdown via the serial cable. That does not make a lot of sense because that cuts the power to the unix server. The unix server is legacy and does not support Network shutdown.
If it still just goes 10 minutes then I probably have a bad battery or connection somewhere in the packs. It does not lend itself to troubleshooting that issue. I would just replace the whole thing, but it is a bit pricey for that.
Yes it is. On your model of UPS, the design of the communication bus is like a chain. Having a serial cable and NMC, which ultimately are on the same chain/bus causes a problem. You can get it to work sometimes depending on order you connect things and playing around but as you found after NMC reboot, it is not a sustainable set up long term. (Newer UPSs have a different design. While it is still not recommended or supported, there are less problems.)
OK. Yes, I've seen random signals come from dangling serial cables or those connected but not running software. I don't think it is the problem at this time based on the low runtime estimate issue but can't be absolutely sure.
My unix admin notified me that yes, his box is set to power down the UPS to save the battery power for itself. This is not really compatible with a shared UPS. It has the added benefit that the server will power back on when the UPS powers back up so the server is as available as possible without human interaction. We don't need that on those servers. This policy was set 20 years ago when the unix boxes were alone.
I recently bought a new battery for my HP Probook 450 G0, and i would like to check if this battery falls under battery replacement program announced by HP recently just to be safe. More details here -
When i tried to execute HPBRCULauncher.exe (aka the automatic way to check the battery) it could not finish successfully and said something like "Unknown battery found. Unable to tell whether or not this battery falls under battery recall programm"
Plus i can't manually check the battery because CT number which is printed on the battery, was partially sealed by "very smart" seller with his own warranty badge. The only part of the number i can see is "CT:6BCM..."
Hi @mcleanm. With the dual battery option, the Spotlight Cam will first use one battery until it is completely depleted, then it will switch to the second battery. I would make sure both batteries have a full charge, then insert them into the Spotlight Cam. In the battery compartment, there will be a red LED indicator light to let you know that battery is inserted correctly.
That is how I assumed it would work. But when I added the second battery on a currently mounted light, it did not recognize the second battery. When the first battery went low, I removed it and at the point the light recognized the other battery and when I returned the newly charged battery, the light did recognize both batteries.
So, we just installed the spotlight cam battery. I charged & inserted 2 batteries. The red lights came on for both & 2 little green batteries showed up in the Ring app. Then after a day, the right battery is not recognized. We took it down, & the battery on the right had slipped out. So I pushed it down good, & made sure the other battery was in & then they both showed up again. Then, we put it back up, & the same thing happened again. Please help!
Hi there, @CoriLyn! The best next step is to check the battery slot for any debris or obstacle that might cause this. Feel free to also compare the batteries to ensure the contact pins and latch hardware is positioned right to click into place (which it should be by default).
An ODYSSEY Battery ingeniously uses unique Absorbed Glass Mat (AGM) TPPL technology to offer, in one package, the performance of two separate batteries. It offers massive deep cycle performance (can be drained over 60% more than any other battery) while still delivering exceptional cranking power to beat any rival.
Compare this to other batteries which fail to provide sufficient cranking below 20% discharge, risking catastrophic failure at the 80% discharge rate that ODYSSEY Batteries thrive on, then you can clearly see the advantage of having a premium battery you can rely on.
A typical starting, lighting and ignition (SLI) battery, for example, is designed to provide short-duration, high-amperage pulses; it performs poorly when repeatedly taken down to deep depths of discharge or if placed on a continuous trickle charge, such as when used to crank a backup generator.

Brownstown Battery Assembly Plant was the first battery assembly plant in the U.S. operated by a major automaker. The plant was converted from an empty warehouse into a production-ready battery manufacturing site in just five months.
