Even "deep cycle marine batteries" can be crappy, with many actually
being a combination of starting / deepcycle. The primary difference
is the plates. Good deep cycles have thick lead plates. Industrial
batteries should last longer. Car batteri

I have many sites that have a 35amp Charger with 2 x 400ah 900CCA deep cycle
batteries (10 year warranty), and 1000VA inverters.
Those deep cycles batteries look quite appropriate... in which kind of
store do you get them?
The combination makes for perfect power and about 2.5 days run tim

Hello,
APC has a nice selector tool on their website.
http://www.apc.com/tools/ups_selector/index.cfm
It asks several questions to recommend an APC solution. it even gives
you a percentage of the capacity of the ups systems capacity.

Use "deep cycle marine batteries" or similar. Car batteries arn't
really designed for "long low power", they're designed for CCA, high
output short burst.

get a kill-a-watt or lacrosse power monitor for $30 and leave it
running for a few days. then you can sort throw the data and know what
your power draw really is..

It's tricky sizing UPS'es to be bang on the money. The rule-of-thumb
calculation for VA is watts/.6 . So, for a 200 watt power supply / .6 is 333

No worry there, since the modems (upstairs) will be unpowered as well.
Although the asterisk
Normally, the power factor is taken as 0.6, thus to convert watt to va,
just divid the wattage by 0.6 to get the va rating.

Thanks for that info. Where does the /0.6 come from? I've always
wondered about VA which looks like "VoltAmps".
There are 400, 500 and 600VA models. The aste
Another thing to consider regarding the ups is the runtime, depending
on the hours and minutes you want the ups to supply power to your
asterisk box, you may need to add more batteries to the ups.
Regarding this, I have done this hack yesterday:
- Remove the battery from an existing UPS

Hi,
Let me try to answer this one.
Assuming your P3-800 is using a 300watt power supply, then in a full
load condition, convert to VA, it will be 300/0.6=500VA. So, it is
greater than your small 400VA box. So, you need a bigger ups. Of course,
if your power usage is actually much lower than 3
Slightly OT, but I think this is of possible interest to many of you,
I need to get a UPS for my asterisk box. They are rated in VA but I
can't quite figure out how that converts to real life.

adapter, an IDE hard drive etc. Will a
