    Car batteries also advanced very much, all sealed with expansion chambers and are not exhausting any fumes. I haven't seen any sulfate or oxidation on terminals for many years now.

    Does it really take nine months to get this done?

    With advances in technology, it could take forever or just might get pay raise and buy something expensive.

    Hey all thanks for all the responses. Few other questions.



    1. So i was given advice from someone else that i should buy the highest VA UPS... thus 1500VA then. Take out the battery. And then put in a deep cycle marine battery like a car battery. That person says that will last it for at least 6 hours. So that is true? The thing was that person said they never bought that battery though and said the process to do this as finding the battery, making a converter and hooking the ups to the battery is a long process. So how long does it take to do this? What places would i go to where i could ask them to do this if i have all the equipment... UPS.. deep marine battery etc?


    What im confused is if you are planning to use it with a deep marine battery, what is the purpose of getting the highest VA one if you don't intend to use that battery? Like if you intend to use it with the deep marine battery... then take out the 1500VA, why not just get the lower VA one? Or does that play an effect on the deep marine battery? I assume not? The person suggest that a UPS would not last a laptop more than 2 hours... so if i want more hours... get deep cycle marine battery... like car battery.




    2. Where can i buy this? Do they sell these on amazon? I see a few of them when i type in deep cycle marine battery

    3. Someone here mentions these batteries might not support my xps 15 9550 laptop? Such that it needs minimum 50watts and some of these don't support it?



    4. So these batteries don't support the voltage i need for my laptop? Also once the battery is fully charged... if i don't touch it a while, will it remain a full charge similar to like how my powerbank has a full charge even if i don't touch it for a while? How much money and what i would need to buy for the product to charge the deep marine battery?


    5. So i can't leave these in my studio apartment. But could i leave them in like a room we have in the building in the 1st floor where they put things like brooms and other things in it? Think of it like a garage so to speak but its more like a room with a lot of dirty things there. Would that be fine? Then if i need it, i go downstairs, open the door, bring it up to my studio apartment and use it? But what confuses me is aren't this battery going to be put in my UPS? Thus the UPS has to be in that room then? Like how would the UPS look? Like if the ups battery is taken out and deep cycle marine battery put in... the whole thing should be closed right? If so, couldn't i leave that in the bottom of my desk?



    This is frustrating because its like unless im in a house where i could use it out, its going to be hard to keep it or use it inside the apartment right?

    Well i first got the dell power companion which gives me 2h30m. I want another 5 hours of backup. I thought simplest way to do this would be get 2 more power companions. But at the moment, i cannot get it where im located at the moment. But i could buy UPS. So thats what i thought about.


    But then i thought if it only gives me 2 hours of backup battery at the most, well a power companion gives even more power so moneywise, its cheaper to get more power companions. But a UPS is good because i could power my modem/router as well.


    Then when i heard about car batteries and how it could give off 8 hours or longer, i was very interested because i had no idea you could connect your laptop to it... and you can remain charged for that long for backup battery. But what concerns me is are there much risk of connecting it to laptop where something goes wrong like laptop burning or things like that? That is a big concern of mine as if there could be damage done. Because the dell power companion, well its like a portable extended power bank so its great and safe to use. But the other things, well ppl say there are safety hazards and issues like that and then there is the oh you can't store it in your apartment. Because if you can't then where do you store it? Your garage? Because there could be a fire there as well though obviously its not the apartment. I mean i can imagine if you are using your laptop or other electronics in your backyard or camping for a while, that is fine. But for what i want to do, which is use it inside studio apartment, its so complicated because people say just buy power generator... but then others say you can't keep it inside etc.

    Hi there

    @Try3

    I did say -- you don't have to use a specific output for your computer --what you do with the device I mentioned was to take the 12V output and feed that into an Inverter which produces 220VC (EU/EEA etc) or 110V US canada etc and then simply plug the mains adpater of your laptop into the inverter --- enough juice for HOURS !!!!!

    However I suspect that the original poser of the topic was on a different "trip" -- if you have something that obviously mission critical you would already have a professional solution for it --in any case if it's that critical you'd need more than 1 computer any way --it's not only the power can fail but what about the computer itself !!!!

    Cheers

    Hey all. So i think i will just buy the UPS 1500va/900W for now. Good decision or not? If so, i will make the purchase soon and then let you all know how it works.


    I mean its always good to have a UPS right? However, the power surge that i use where i plug all my electronics such as laptop, modem, monitors seem to work fine if power outage happens. Again i never had a UPS ever.
