Thinking to get this UPS to protect the ONT box

[Phil2008]

So a few days ago the ONT box got fried somehow when I turned the electric on to the house.. The power and lan light lit up but the other green light was off. BT came and replaced the box, I was going to ask him if I could have a spare one but its not as easy as that is it, dammit.. So Ive came across this cheap UPS that will not just protect the box but will keep the phone and router working in a powercut for 30mins or so.. and and apparently its generator friendly, so it should play nice with my generator too.. Your thoughts?.

Well apparently the battery is quite easy to change and with the UPS being plastic you have less chance of shorting the dam thing... Yeah its not a 10second job but it looks much easier then my £350 1800watt UPS to change that batteries that Ive just done btw

My PowerWalker 1800watt online UPS...... The 2 compartments are cool, 1 half contains the batteries as you can see in the pic and the other contains all the electrics. But the metal case doesnt help and the batt terminals face inside the case, so the batts are a real pain to connect when you cant really see or get to the terminals easy.

The CyberPower 360watt UPS.... That looks sooo much easier to replace the battery and theres only 1 battery to replace aswel.. But I did a search for that battery, but I couldnt find 1 online?

I wonder how many others use small UPS or some form of battery backup to keep the internet on during a powercut.. For me its been a bit of a downgrade with not being able to use the old copper phone line, because we rely on the landline as mobiles dont work where I live, so I dont have access to a phone if the net goes down or I have a powercut... Thats the worst thing about going full fibre, its like putting all your eggs in 1 basket scenario. It took BT 3 days to come and replace the ONT box, I just hope I dont get charge for the new box because its inside the house?

Its a shame that BT didnt provide there own way of powering the ONT boxes like with the old copper phone cables, as Im guessing it wouldnt be hard todo, putting a power cable alongside but in the fibre cable so to keep everything in 1 cable?

In the end I bought a APC surge protector as my family isn't fussed with having no phone when the powers down, and I have a generator, so its not too bad when we have a powercut anyway... The 1 problem with my generator is that because its portable its not grounded, and surge protectors needs tobe grounded so to protect. I did try the surge protector on the generator and it worked fine but obviously the ground light wasn't lit on the surge protector... So is it still ok to use the surge protector on the generator, it just wont be able to protect stuff?

I would be wary of using a modified sine wave ups with telecoms equipment. I experienced a power cut a while ago and the kit was sounding terrible. I buy APC ups and just order the batteries from reputable suppliers. CSB are good, as are yuasa. They are also OEM.

I replaced my UPS CSB batteries with these about a month ago....... https://www.allbatteries.co.uk/ups-battery-nx-9-12-ups-high-rate-12v-9ah-f6-35-amp90106.html
