Router Battery Backup

elf_lord_ZC5 said:
When new, it was doing fairly well, but the level of load shedding was also lower. If memory servers the current battery has been in use for the past 2 or 2 1/2 years.

Now it gives a low battery warning on the Hyyp app within 15 - 20 minutes of the power going off.

Tho the church is basically 2 streets down and 3 blocks away from where I stay. It is in a different load shedding zone, and it gets cut a bit harder than we do, no idea why.

Besides load shedding we have started getting unexplained power cuts that can last a half hour or longer that are not load shedding, related.

Also the local feeder sub- station has taken to tripping every once in awhile, especially after we get some rain.

Edit: Power went of at 06:08 just now at 06:45 I got low battery message.

Yes, loadsheddings has not been this prolonged before, that battery is now done for because it discharged too deeply too often. The Blue Nova would not degrade like that., if you can get extra charging, great, if not it will at least handle it the same as the other one when it was new and not degrade like it did.

Thanks, not looking forward to climbing into the false ceiling to get to the battery and alarm unit. The Lord alone knows why it was installed where it is, because I don't.

Will have a look at what charging unit it has.

A bigger battery (maybe 11 or 18ah) and faster charging would be best I think.

You stayed with the 7.2 A/H rating or did you up it a bit.

We were running 2 7ah lead acid batteries in parallel, but they just don't last. Changed to an 11ah Blue Nova battery that is working just fine. Our alarm has a fair number of sensors and a micro-controller that communicates with Home Assistant

It's possible that the previous battery was discharging too deeply too often. The question is how deeply? 60%, 70%, 80%.

If you are going to be discharging a similar capacity lithium battery more than 80% frequently, it's rated cycle life will also degrade.

Establish the load on the alarm and the charge rate of the alarm. Get a battery capacity that when subjected to that load for 4 hours, does not exceed 75% of the batteries capacity for lithium, 45% for lead acid or gel. (This is not scientific, just a rough guide) then using the devices charge rate, determine whether you can replace the consumed load at that rate in 4 hours.

If not get a higher capacity charger, for lead the charge rate should not exceed 10% of the batteries capacity, and for lithium you should get a lithium compatible charger, that does not exceed 30% of the batteries capacity.

The most important ingredients are the load on the device and its charge rate.

As an aside, an alarm system that is installed in the ceiling is not saidsa compliant, and cannot be issued with a certificate of compliance. Would be important consideration for insurance purposes.

Thanks, will talk to our church council, and see where we end up.

Might not be a bad idea to stop off, at the Regal Security shop I ride past almost daily. One afternoon when I have time.

It only comes with one size splitter that is very short so you might need adaptor and extension. Both devices need to be 12V.

Did check it is 12V just want to know what size plug each use and the size of the splitter to buy the right adapter for it

I know the splitter fits the AX3 as that's what I have too, but sorry, I can't comment on the ONT, my Nokia ONT from metrofibre uses the same size as the AX3.

Thanks so that solves it cause my ONT isn’t the same as the AX3 so will have to get a splitter

Do you know what size the AX3 uses like you get 5.5mm etc
 
Bought two of these. Price has gone up since I ordered. Sold as 12000mah but had both these stickers. Would have been really nice if it was 24000mah :D

Also purchased one of these from TAL, never held it's charge for longer than 20 minutes. Returned it and just paid a bit more for a Gizzu.

Since our speciality is cctv we use these battery backups for may estate perimeter cctv banks.

The issue is that they vary between 0.5 and 0.8Amp charge rates, which is not enough to recharge a 100W to 150W load in 3 h-4 hours before next load shed- we have on average 5-6 cameras and Ubiquiti Nano Station on each bank.

We have replaced the 18AH Gel/lead acids with 22AH Blue Nova and added compatibel 7 amp smart charger. This works very well.

For small camera loads 1- 1.5 Amp these units with an 18AH lead acid battery seem to work quite well.

How do you replace the charger?
The CCTV PSUs have a built-in charger, right? So how do you put in a more powerful charger and still have it switch from AC to battery when the power drops and so on?
