Hot!? Dynex 800VA UPS for $39!

My local BB is still selling the Dynex 800VA UPS at the BF price of $39. I think this is a very good price for an 800VA UPS. Regular price is $89.
 
is that after rebate? i really wanted a 1500 because with a 19" lcd and a fairly built up computer (with high wattage psu) youll probably realistically only be getting 5 minutes MAX out of this (dont trust what the manufacturer says on the box) but this deal is pretty good.
 
nice. I like the cyberpower's - I've got a 1250AVR and it's been terrific. 'Course, I also have a couple of APC's, Belkin, Eveready, TripLite's...but the Cyberpower is my favourite. 🙂

Not so sure it's wise to mix a 6volt battery with a 12volt battery in a UPS unit, wouldn't want to take the chance on it leaking or gulp, exploding on ya 😉. Besides that's expensive compared to what other merchants charge for replacement SLA batteries.

A few ebay merchants have 12v SLA replacement batteries for dirt cheap, here are some the better ones that i bookmarked.

That's why you put two in series.
 
I got one of these on BF, I could have sworn it was a 1000VA....have to check when I get home. Anyhow, it was a pretty dasm good deal, even came with cables and software.

Never heard of overclocking your UPS? lol 😛

 
I've been looking for a decent UPS at a reasonable price for an eternity. This is just what I needed! Thanks a ton, StormRider.
 
Great post!!!
I bought two of these on Black Friday and was wishing I had bought one more for my home theatre system because of the line conditioner for cable.
Thanks again for the post!
 
i don't see an SL series 800VA model on cyberpower's site, is this really the same thing?
 
You can't swap higher capacity batteries into most off-the-shelf UPSes. That's not just because bigger batteries won't fit in the box; the standard charger circuitry is also unlikely to deal well with more capacity. If a charge takes longer than it should, or the charge current goes too high, the UPS is likely to assume there's something wrong with the battery.

Better commercial UPSes have a standard battery expansion connector; some cheap-ish units will deal OK with more battery capacity, but you have to solder your expansion cable to the appropriate terminals inside to make it happen. Don't bet on this being possible with J. Random UPS, though. And the more capacity you're adding, the less likely it is to work.

Oh, and if your cheapie UPS isn't expecting more battery capacity, it won't be expecting more run time either. So it may overheat and die, if forced to run at something near to full power for much longer than its standard battery could manage.

Use a dumb charger, like my DC power supply and a dedicated inverter of reasonable quality, and you won't have these limitations. You have to keep an eye on your battery, and you have to set your voltage carefully. But you can also use a bank of truck batteries to power your PC for a week without mains, if you like.



This is a good read ... The DIY (or, if you must, "Ghetto") UPS
 
This is ABSOLUTELY a CyberPower UPS in a Dynex box (with a Dynex logo where the CyberPower logo would normally go). Model number is CyberPower CP800AVR. The best price online is at Amazon, where you can get it for 67.44 shipped. This is almost half off of that price, so it's clearly a hot deal.

My local BestBuy is still stuffed to the rafters with these (well, at least 20, which might reach the rafters if you stack them on end and the rafters aren't too high).

I just picked one up. They were in a pile separate from the other UPSessesssesss. When I told the salespeople they were $39.99, they said, "No, they marked them back up to $89.99 after Black Friday." So I asked if they'd look it up. Sure enough it came up $39.99. I heard one say, "Hmm, maybe I'll pick one up then," as I walked to the register. 🙂
