I've never had to run on the UPS for much more than a few hours but that's good because the batteries never get tapped to drop their remaining capacity below 75%, which makes for a very long battery life. The APC gel batteries couldn't handle the deep discharge and had to be replaced frequently. I was, and still am, running video security stuff that had to be up 'always' and with some of the power outages in my rural area lasting 3-7 hours, that wasn't enough. I used APC units in the beginning but the largest that I had (1400-Smart) was only good for about 95 minutes tops (discharged to 10% of capacity).
The batteries are rated to last 28+ hours with a low 8 Amp draw which is about 192 Watts and my PC, monitor, TV, only draw about 166 Watts. Total cost $2,100+CAD, in 2005, no idea what the cost would be today. PCs)ģ) two Lifeline Marine GPL-4CT batteries - 6 volt AGM type, in series = 12V (these weigh 66LB each!)Ĥ) PowerPulse desulfator to keep batteries in good shapeĥ) Watt Meter to check power consumption to verify how long batteries should last I bought individual components and 'assembled' them:ġ) Xantrex 40 Amp charging unit 120VAC-12VDC, has setting for AGM type batteries, quick recovery when AC power is restoredĢ) Exeltech XP 1100 watt pure sine wave inverter 12VDC-120VAC, the best for electronics (e.g. Thanks for the explanation, it's not one that would have popped into my head right away. That's a bit like the commercial where the two boys aren't sure about a new cereal so they 'let Mikey try it first", I let the other guy go first. I know that's what I do and I've been lucky and avoided problems when all the auto-updaters were bitten severely. Perhaps you might consider just doing manual updates. But from what I've read, it's one of the most reliable over time, so stick with it, it's a good choice. I'm willing to forgo the effort to set all that up that since 3 seconds is OK, and especially since I'm the 'slow part' of the operation here.Īvast isn't the only security app that's had problems like that, or other problems that should have been caught by thorough beta testing. If I had everything, program and spreadsheet, in a RAMdisk, it might cut the time down to less than a second. I didn't have the program in the RAMdisk so that still had to load from the SSD and at a guess the time was about 2 seconds. I haven't tried any other 'ramdisk' so I can't help you there.Ī 'ramdisk' is probably a great app for folks that have slow HDDs and are continually accessing (a lot of) the same files over and over and that will fit into an image file in memory.Īs an example, a 700MB spreadsheet opens and is ready for use in about 3 seconds from an SSD. I tried RAMdisk Kevin but my needs were/are very simple and since all my drives are Sata3 SSDs, I didn't see much difference in speed, at least for what I tried.
