i just bought 2 APC Smart UPS SUA1500i.
i already had a very good Local UPS 1000W for use with PC. . just had 2 new Exide 185A batteries installed with it 3 months back.
i connected the APC to the entire setup, very hectic task and it started up. initially it also detected my previously almost 3/4 charged batteries as 2 bars, and charged them upto full in 2 hours.
now the problem is, that when checked with a meter, the cables are charging the batteries at 4-5Amp.. the previous UPS used to charge at 18-19amps dead battery, 10-12A after loadshedding, and 3-7A average.
now the APC in our market are supposed to be charging enhanced UPS, and should charge upto 10 A on dead battery.. mine started charging at 3-5Am fluctuating. i used up batteries till UPS shut down in 3 hours, and then starterd charging dead. again 4-5Am only
the problem is that, either its not enhanced by the APC software yet, or improperly done. orrr... the ups is incapable of faster charging.. the Official APC spec says, its supposed to charge at 6.8Amp max. meaning i m charging default specs
the other thing is that when i disconnected and reconned the UPS after deadening the batteries, it again showed 2 charged bars where as it should have been empty.
as for 2 heavy 185Amps batteries, they should charge in about 8-10 hours to max capacity. where as this UPS is charging them to 5 bars in 3 hours.. WITH pc using lots of power.
1 - what serial cable is required to connect this UPS to PC for using the APC software?.. there is no usb port, the sellers removed it.. any Serial to USB cable? and from where to get in lahore?
2 - would i need an external rapid charger with these UPS? cz i wud have to buy 2 of them , one for my PC and other for Home. extra cost..
3 - is everyones APC Ups charging such huge bateries at this speed? and in 3 hours?. the desi UPS used to give around 6-7 hours Backup, this only gave me 3 hours. in same day.
HELPPPP me understand this craziness..
