What are the cons of using an external battery charger for charging my UPS's external batteries while the UPS is on?
I have an inverter/UPS with external battery. I am tired of constant PC reboots caused by power fluctuations in my area.
I have tried finding a solution to the restart issue, but did not get enough solutions posted here: http://www.tomshardware.com/answers/id-3537573/rebooting-power-fluctuations-connected-ups.html
I have 2 PC's; one of them keeps rebooting at power fluctuations. The UPS is working fine.
I am thinking of buying an external battery charger for the external batteries of the UPS.
The UPS will be switched on 24x7. It will get 12 v DC from a charger while the main power supply is available or battery in case of power outage.
Like this:
MAIN POWER => BATTERY CHARGER => BATTERY => UPS => COMPUTER
UPS's mains will be switched off, so UPS will be on 24x7.
Before buying an external charger I would like to make sure that this is a feasible solution. What are the cons of doing so?
1) Will the UPS heat up? (UPS has internal fan to pump out hot air)
2) Will this reduce battery life? If so, by how many years ? (The battery is 1 year old)
The battery I'm using is an exide tubular battery 180ah: http://www.powerwale.com/store/exide-inva-tubular-it-500-plus-150ah-battery/77315
The charger I have in mind is: https://www.amazon.in/12Volts-10Ampere-Alkaline-Automoblie-Inverter/dp/B01C00JDY6?tag=googinhydr18418-21
Currently the UPS runs on battery when the power goes down for 12 hours continuously.
Any thoughts?
Update:
The PC only reboots if it is using 100% CPU, i.e. doing some CPU intensive work.
So it looks like when the PC is at 100% load and power drops, the PSU is unable to hold the power for too long, hence reboot.
1Why? A UPS should already reduce the power fluctuations. If it is not, it's likely that you're not using the right kind of UPS for the job. Why not get a UPS that actually fulfills your requirements? – Seth – 2017-10-10T06:15:02.203
one PC works correctly one reboots., who's at fault ? – AMB – 2017-10-10T06:16:17.270
12 hours? This question is not suitable for SuperUser. Try ServerFault.com. (Maybe NetworkEngineering.SE) What you mention is well beyond typical home equipment. You may want to read about daisy-chaining UPSs. (Simple answer: don't do it.) As requested, those are my thoughts. – TOOGAM – 2017-10-10T06:17:59.193
You changed the power supply on your computer and its still broken. As such either the hardware itself might be faulty or you changed your workload. Does your UPS offer you any data on what happens if your PC reboots? Like do you see a dip in voltage supplied by it? Did you check the temperatures of your components? Some of your components might also have aged depending on how long you've had that system. In addition you will see faster degradation if you run consumer components 24/7. You followed the advice on the other thread like the person mentioned I guess. – Seth – 2017-10-10T06:25:12.120
@Seth maybe 450watt PSU is not enough ? as both PSU i checked are 450 watts, workload is same, which hardware is faulty ? motherboard ? . UPS does not offer any data, just few LEDs. PC is 2 years old, and UPS is 1 year old. so i am not sure, which componenet is aged. thanks – AMB – 2017-10-10T06:42:18.283
What make and model of UPS do you have at the moment ? – davidgo – 2017-10-10T07:15:28.910
