Don't worry about the warranty. It is so full of exemptions so that the warranty will not be honored. That warranty is a sales promotiong - nothing more.
Do batteries in UPS absorb the surges

Id tell porkies if a storm fried my pc anyway
But yeah I guess they will be able to get out of paying up some other way.
But if a surged fried the ups and not the equipment thats attach to it,, thats a result in my books cos its done the job that its designed todo.
About 5-6 yrs ago a storm fried my pc, but I had no protection,, There was a huge crack of thunder, and it tripped off our mains. When we put the mains power pack on, my pc was dead as a nail

Then you did not learn how everything is connected. If a surge is on the UPS, the exact same surge is also on the computer.
To promote a scam, the naive will claim that UPS is blocking surges. Nonsense. What is a computer connected to when UPS is not in battery backup mode? Directly to AC mains. Nothing but wire between that computer and the surge. And the surge absorber? Read the spec numbers.
Grossly undersize a protector. Then a surge woefully too small to harm the computer (and so many other appliances that are not as robust) can destroy a protector. The naive will do junk science. Assume. "My protector sacrificed itself to save my computer."
Reality, only protector that provides effective protection remains functional. Remains functional even after protecting from direct lightning strikes. Effective protection means nobody even knew a surge existed. But that does not get the naive to recommend it.
If a protector does not make the always required short (ie 'less than 3 meter') connection to earth, then it is not effective. Also obvious because its numeric specs do not list protection from each type of surge - in numbers.
All appliances have significant protection. Computers are even more robust. Intel ATX specs demand computers withstand thousands of volts without damage. IEC and other standards make same demands. And so the protector myth lives on. A computer protects itself from surges too small to damage anything but that grossly undersized and ineffective protector.
Read spec numbers. It claims near zero protection. Which is why surges too small to harm the computer can damage the protector - so that junk science assumptions will claim it did protection.
Ummm.. one or two of you are saying Ups are basically useless and Im not disagreeing at all, its intresting stuff, so why do we have ups and surge protectors and if I were protected 4-5 yrs ago, would my computer had a better chance of surviving through the sudden storm??
The UPS constantly monitoring the power before it gets into my stuff??

UPS does only what it claims to do in specs. It provides temporary power during blackouts and extreme brownouts.
Now add some near-zero protector parts. That means sales brochures can hype 100% surge protection. Does it provide effective surge protection? No. It only provides near zero protection. But the majority will now hype it as a surge protector. Same process proved Saddam had WMDs.
For over 100 years, surge protectors made even direct lightning strikes irrelevant. But no protector is protection. Those protectors worked because of a short (ie 'less than 3 meter') connection to what provided protection.
Why are companies such as Monster also in the surge protector business? Hype a protector without earth ground, then claim surge protection in sales brochures. No claims for protection in their numeric specs. But a majority will again preach the myth.
What exactly do you want to solve? Which power anomaly? Most forget to start with that question. Then consult salesman as if experts.
Effective surge protection for any home costs about £1 per protected appliance. But an overwhelming majority do not learn this. Sales propaganda is, unfortunately, the only information source for a majority of consumers.
Typical UPS connects your appliance directly to AC mains when not in battery backup mode. If voltage drops so low that incandescent bulbs would dim to maybe 65% intensity, then a relay switches over to ‘dirty’ power from a battery.
UPS circuits are so simplistic that a replacement battery may costs as much as the entire UPS. Circuits so simple that, for example, if you power a second UPS from a first UPS (in battery backup mode), then the second UPS will see no power. Instead switch to its battery. Same reason why a UPS may not recharge its battery from less well designed generators. A UPS does not monitor power. A typical UPS does everything as cheap and simple as possible. So simple as to easily be confused by anythng but ideal sine waves.
So what anomaly do you want to solve? That is where an answer begins.
