Router Battery Backup

Was considering plugging out my router backup. Does being on standby degrade the battery in any way? Don’t want to encounter load shedding then the batteries is ‘pap’ from this unnecessary standby.

I think it's better to keep it maintained by a charger... it's the low drains which will kill the battery.

Ordered the converter last night, plus another one with USB 5v output. Will build it into a box that will give 12V for the ONT, 9V for the router, 5V USB for charging a phone and another 12V output for lights during load shedding.

Finally got the parts this week from Amazon. Built it all into a 30L plastic crate. Box is now giving 12V to the ONT, 9V to the router, and there is a 5V usb plug as well for charging phones. I also have a spare 12V point to connect 12V LED lights during loadshedding. With the 45 Ah battery in there its should last for more than a day on backup power.
 
I may have missed it, but is there a site where one can input voltage, load, etc to then work out what size battery / UPS is required.

I installed a power monitor on my network equipment and NAS, and it draws about 65w on average. If I want it to run for 10 hours - what size UPS do I need. Would love a solar charge option like that Ratel so that at least during day in case of loadshedding or just normally, sun can charge batteries. I want it as plug play too 220v output (so I put plug in) to UPS and everything remains powered up with their PSUs / adaptors. Don't want to have to worry about different voltage management for the multitude of devices I have.

If that is all you want to power than you only need a 100VA inverter. To run it for 10 hours you'll need 135Ah of 12v battery (assuming 50% dod and 80% inverter effeciency)

I threw out my ancient alarm power supply, then used a Sherlo 6.4A charger with an 18AH battery which fits inside:
www.alarmtec.co.za

Sherlo 6.4Amp Charger

Sherlo 6.4Amp battery charger is a robust and high-powered device designed to efficiently charge a variety of batteries up to 18ah 12v.Equipped with intelligent charging technology, the Sherlo 6.4A...
www.alarmtec.co.za www.alarmtec.co.za

It has 6x1A 12V outputs which I use for:
- CPE
- Old Alarm (battery removed)
- 5V Converter: Router + SIP Phone
- Router
- Alarm beams + 5V Converter to PI Zero

It's pretty DIY, but one could use car chargers for the 5V supplies to keep the DIY to cutting off adapters and connecting wires.

My guess is that this should run for 6h.. just a guess, but the 2h load shedding shouldn't kill the battery too quickly.

Interested in this setup because my alarm system is right next to my router. Can you take pics?

Thanks. How did you work it out? I know i am being doff. Thanks to Eskom,.time to get solar for whole house

Inverter and batteries

Oh how I am so glad I got everything sorted at the start of the month. kept simulating load shedding to see if everything worked. Then the real thing started. What worries me now is when we go into Stage 5 and we get a 5:00 block and 2 x 2:30 of load shedding in a day. My batteries will dip...

Oh the irony. Switch over was seamless. Will check battery level once it comes back on.
 
So a friend of mine in Joburg needs help getting a battery backup / inverter etc. for his TV and Internet. Not a DIY type so he'd prefer to go somewhere where they can advise him what to buy, sell him the stuff, and maybe even help set up at his house.
Any suggestions please?

Thanks Guys

It's a mess :) Here are my routers hanging upside down in a cupboard.

Then one of the common variable step down voltage regulators adjusted to 5V.

How much is this part?
What exactly does it do? does it switch everything from mains to batteries when the power drops, or is it just for multiple outputs from the batteries to your devices?
 
Looking at the Omipower Ratel 430m Micro DC-to-DC UPS to power a 9v router and a 12v Vumatel CPE/ONT during loadshedding - the specs lists the DC interface as :

DC Interface
Output Voltage (selectable) 5Vdc ; 9Vdc/12Vdc ;12VdcX4.

Is it possible to select 9v and 12v simultaneously on different ports or is it either the one or the other for all the ports then, and how many ports are there for DC ?

My step down converters from banggood should be delivered this week then I'll hook them up to the cheap UPS' I got from Incredible Connection.

My one Incredibly Cheap UPS has already been hacked (quite literally) and is now boasting 2 x 9Ah batteries. The step down converters I got from banggood is unfortunately still not included in my setup as the output on mine, while being adjustable, varies as the input changes. So as the batteries go down from e.g. 13V down to 11V, the output steadily drops as the input voltage drops.

Was able to run my 55" TV for almost 2 hours (after turning on the eco settings and turning down the brightness etc) - did not conclude this test yet as it became too late and I did not have a multimeter to check the levels on the batteries properly.

nvm, found your original post with a link to the price.
So if I understand correctly, it charges AND switches to battery when the power drops? Is that right? If so, may be exactly what I'm looking for, except I have a smaller battery
 
I discovered Sherlotronics is around the corner from me in Northriding so went to their office. I'm going to sign up with them as a reseller as they have two neat units. Price is awesome.
Anyone know where I can get a 12v to 5v stepdown?
