How does the battery pack compare to the UPS itself in terms of operating time at a specific current draw?

Check out the chart on APC's website. The top curve 'B' is both the UPS and expansion battery.http://www.apc.com/products/runtimegraph/runtime_graph.cfm?base_sku=BR1500GI&chart;Size=large

The battery pack triples the run time of the UPS. Which is what would be expected since the battery pack adds two more sets of batteries to the UPS. I get about a 60 minutes run time with a 400 watt load on the UPS. The newer battery packs are easier to open to replace the batteries.

With a 7% (about 60-65 watts) load, I have approximately 314 minutes of run time. The link to APC's site that Raymond Scanlon posted will give you a pretty accurate view. If you need long run times for attached devices, you will have to buy more UPS units and decrease the load on each. However, if you have a whole house generator, you would typically only need a few minutes or less run time just to keep things going until the generator is on-line and the transfer switch has kicked in.

At a load of 500W, the runtime goes from 10min to 40min with the added battery pack.

I'm not sure, because we use it as a battery backup to our server. The times I've needed it, we've gotten at least 2-3 hours of backup for our server before our electricity came back on.

Yes, you can have a ups to plug your psu into. I would looking at the AFC BE750G Power Saving Battery Back-UPS it will last for about 30 minutes after the power goes out.

You need to go to the APS websight and plug in your model in the battery replacement indicator. The site address is: http://www.apc.com/tools/upgrade_selector/index.cfmThis is how I determined the correct battery for my UPS.

Whether it is 7 or 7.2 amp hours is not really an issue, they are interchangeable and you won't notice any difference in actual operation. I don't know what the actual weight is since I didn't weigh it and is already installed in my ups. I would estimate that it weighs at least two pounds, maybe a little more.

Be sure to check the physical dimensions of the battery. If the new battery has a reasonable charge on it, the only effect will be the rate of charge. During a black-out, it will keep your computer up for a longer time. The main issue is whether the new battery will physically fit into the UPS.

I agree with the other posts . You need Deep cycle batteries but you also can find power inverted made to accomplish this task the only question being capacity wattage and if it has pure sine wave out put as long as your load isn't more than what the inver can provide and battery has enough capacity & is of correct type then you should be fine . Never however modify or tinker with UPS and modify it beyond what the design say .

Hi,Theoretically, good SLA batteries life time would be around 3-4 years, if UPS system is not frequently discharging/charging batteries. On the display you can see battery's charge level. When level is not on "max" and stays this way no matter, how long is charged - it could be good signal to replace battery. In my application I replaced battery with external block of four original batteries connected parallel because I needed more power to be delivered with long period of the time.

5 to 6 hours which is not bad considering, another back up battery its very helpful for a maximum user. I love it . and plus if you plan to go that route for a spare battery you van also have that chargin, while you connect your USB charger to just charge it from your pone as well come with a built in USB charging port.

The UPS also acts as a surge protector. A few of the plugs are supported by the battery power backup and others are just surge protected.

8AH. as written on the battery. Got couple of those long time ago for a UPS and they are working perfectly.

I have used a similar battery to replace batteries in 3 ups. The most important thing are the dimensions. Terminals can be a problem but width differences can be handled with different connectors. The f2 is about 1/4 inch wide. The 1280 is an upgrade from the 1272 battery.

I have actually tested this but not with UPS's that have Pure sine wave. When I tested this with cheaper ups's it resulted in damage to the second inline ups. Also both batteries drain at the same rate so does not give you double the time left. There are ups's that are actually made to be run in series but those are expensive as we use them in our office at work. Those are made different then these.

Rajesh, The run time depends on the size of your battery not the inverter. Joe

I used this in a UPS (uninterruptible power supply) for a computer. They battery is rarely activated, and the last one I got lasted over 5 years. I would check the VA and make sure its compatible with the equipment you are planning to use it with.

Please, people. He's asking how long it would last at full load. It's a pretty common question for UPSs and when it's asked, it means FULL LOAD. Answer his darn question. WILL THIS UPS LAST FOR AT LEAST 30 MINUTES AT FULL LOAD? HOW MUCH LONGER?

Assuming this is the same product as the one in this link http://www.cpap.com/productpage/c-100-travel-cpap-battery-pack-s9.html, then see para: Set As Battery Backup under Features. If same product (which it appears to be), then - Yes - it should be able to be used as a UPS, but it still reduces lifetime of battery expected 4-500 recharges, so budget for a new battery every 18 months or so if used in that fashion.
