how long will the battery run during a long power faiure?

I would say it depends on the battery you buy for it (not included with the pump) and the height that it will pump the water up to to get it out of the basement. In my case I bought one of the Marine size 27 batteries and the pump has about 9ft to lift the water from the bottom of the sump up to where it exits the house. From my research back when I bought it I felt comfortable that this solution would keep the basement dry for at least two days while emptying the sump once a minute (extreme downpour). I can't quote anything more specific than that but I believe reading the other reviews helped... and Google.

I would estimate that the battery would run the pump for 1.5 - 2 hours on a full charge. With my set up, I use a gas generator as back-up power. The 1 hour window gives me time to get the generator up an running.

I guess it all depends on the battery and how often the pump will turn on. Get a GOOD Deep cycle marine battery and it will go for hours. I got it for peace of mind just in case the power goes out. Hasn't run yet, but neither did my AC sump.

I deliberately cut power to unit for 6 hours and it was still running strong.

Sorry, have not had it run for that long. Longest the power has been out is an hour. It ran about a dozon times in that period with no problems.

I haven't had the chance to see how long it would run on battery. It depends on the quality of the battery, pick a good one.Also depends on the 'lift' as another answer suggested. I ran a test for a couple of hours and it had no problem.Also suggest testing battery several times a year (some recommend monthly) as constantly charging a battery will eventually wear the battery out. Battery life is 2-3 years under these conditions, sometimes longer but don't bet a dry basement on it.

There are two 8.5AH @ 12V batteries, so to Dan's comment it would run for 1 hour and 20 minutes.

At least an hour and a half (which is the amount of time we ran it on battery, we usually use it with the wall plug).

depends on what kind of battery you get and how long you let it run without turning it off.

Around 2 hours, the actual operation time will depend on how much electricity is required by the device and how you use it.

Hi Hafeez, the battery can run up to 3.5 hours in normal usage.Thanks, PCrush

Batteries last according to power consumption of usage. Anywhere from 1hr to 3 hrs depending on what your doing. Keep in mind that Core i7 processors draw more power when used at high percentage than most other processors.

If you are asking how long a fully charged battery last until it runs out power I'd say about 4 hours running a PC with few applications. It is worth the money I pay for it.

To answer your question, yes, it can run solely on battery power for at least a handful of hours if it's completely charged prior to use. The company recommends a full 24-hour charge before using it for a prolonged period of time, whether it's plugged in or not. If you're just using it for an hour or two, it's fine to keep unplugged, but any longer than that, and I'd say plug it in.

it may run it quit a few hours !! if the charge was full. not sure as to how many hours and it may take you using it before you need it for power .that way ou will have a good idea . good luck

Actually longer than it did on the original battery. It runs for about 1 3/4 hrs.

A hour or two. Very worthwhile. The price is cheap enough to have sufficient power to do the job. Don't plan on a quick recharge. Just have enough for the job. If the job is very long. You can recharge while the other batteries are working.

1-2 hours, depending on the condition of the battery. The heater draws over 7-amps.You really need a much bigger battery. Deeply discharging the battery frequently will significantly shorten the battery's lifespan.We use ours in a motorhome to preheat the bed in the evening, running it for about a 1/2 hour.It draws too much power to leave it on overnight unless we have shore power.

At least 20 minutes. It seems Greenworks has figured out the battery thing. I had a Roybi 18V and its run time was 10 - 15 minutes. This runs much stronger and longer.

Operation time for extended batteries(12-cell, 8800mah): 4+ hours, however, the actual operation time will depend on how much electricity is required by the device and how you use it.

It depends on the charge status of the battery. Sometimes 5 minutes will do it.

I have used it 30 mins. at a time without decrease of power. Have had no need to try usage longer than that.
