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.
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.
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.
