This has probably been asked before, but I don't have time to read throu all the posts:
I want to use a 800 watt pc ups to power a circuit in my lounge that has just a tv / hi-fi/a few decoders,vcr/ couple of lights etc.
Won't attempt the amp unless it was on at the time 'cause it won't withstand the caps sucking that initial charge.
I want to hook up a couple of big batteries instead of the miserable 10 amp alarm type job that comes built in and lasts maybe 10 minutes at max wattage.
I plan on useing a APC pc UPS not designed to run 2 - 4 hours. Ill add an extra fan to cool the heatsink for the trannies doing the prolonged driving, but my question is:
What happens when the power is restored and those couple of 100 amp batteries i connected together are almost dead and drawing like 40 amp a pop?
Pop to charging circuit? or will they happily trickle charge over the next week before next outage?
Someone *must* have done this by now - so what happened ?
