Duracell PowerSource 1800

This is the coolest thing since cheese cake! It works great. Please disregard the idiots who said they only had it 10 minutes and couldn't get it to work. YOU HAVE THE CHARGE IT UP FULLY FIRST, which only took 3 hours. It read 9% for the first 2.5 hours, then read FUL as stated it would. And to the guy who said it only lasted 2 years…THAT'S PRETTY GOOD. It's a battery… you need to have them replaced, just as the booklet states!! Try Battery Masters for replacement. Please read the booklet that comes with it FIRST before you mess with it and determine it doesn't work. IT WORKS GREAT. I live off the grid, and it's all I need for my electrical needs. Of course, I also have a small generator to charge the Duracell, but at night, when I want peace and quite for small electrical things, its perfect. Telephone, LED lamp lights, a TV, etc. I think its well worth the price, as I don't want to invest in a large battery bank. This product works for me!!

Bought this recently from Amazon for $180.00 I will say its worth about that. I tried a few high wattage things in it like a hair dryer, Iron, coffee maker, just to see how long I could use it. These are things I could never think of using in a standard 1500VA UPS, (Which I have for comp and such) All of the devices ran well, the hair dryer probably sucked it down the fastest, (Set high 1500watts), lasted aout 7 minutes before the warning started going off. The unit ran about 5 more minutes on medium setting before the battery dropped to 20 percent. The battery did recover to 50% after turning off dryer, so high wattage appliances I think are a bit much for the batteries to output continuously. The unit is heavy, about 60 pounds. For the money, I would buy again. I figure I should get about 6 hours on a computer with a flat panel attached. For most short power outages, this will get you by for a few necessities. Anything longer you will have to go generator. The description reads as though you can use it for a fridge and other high wattage appliances, which I guess is true, but misleading as I would imagine a fridge would kill it in about 10 minutes or less. All in all glad, I was able to purchase for the $180.00. If nothing else you can dry your hair when the power is out, and make coffee, without having to hook up the generator. UPDATE: So I wanted to update this review. The unit gave out after about 18-24 months. Cant tell exactly when it lost its capacity but it would last maybe 5 minutes on light load. I took the time to tear it apart and found three 12 volt 17ah SLA batteries wired in parallel. They were pretty much useless. Tried to bring them back but as most here know once an SLA battery gets near end of life it is almost impossible to get them back from the dead even with a good quality desulfator. I got lucky and found 3 new Panasonic replacements for $25ea on EBAY and installed those. (A good quality SLA battery in this range is usually about $70 bucks each). Unit is back up and running like new. I would assume most people would not attempt this nor probably should they. High risk of shock even with the unit unplugged. And many parts to disassemble/reassemble. If you do attempt, take lots of pictures as you break down and be carefull of wires. Doesnt matter how long or how many times you have handled electricity, only takes once.

I purchased the Duracell 852-1807 to provide generator free backup power for the sporadic power outages we have in the Northwest. The product provides a steady 1400 Watts of power (surging to 1800 Watts) which is enough to keep the refrigerator going for 10-12 hours. We are using the Duracell 852-1807 to provide lighting. When the power goes out where we live it is often out for days. In these cases we replace the bulbs in the living room with CFL which helps to keep the overall watt usage down while providing sufficient lighting. You can generalize how long the product will work for you by totaling all of at the values on the wattage sticker each device you want to run. For example, we use run four 20W CFLs when the power goes out. 4 x 20 = 80W. 1800W available / 80W = 22.5 hours theoretical run time. Since batteries don't discharge in a linear fashion I calculate the run time at 80% which in this case is 18 hours. By my reckoning that gives me 4.5 evenings of light available (assuming you only run the lights at after sunset). It is important to remember that the deeper you discharge a product like this the longer the recharge takes. What is really great about this product is that it switches to backup automatically and recharges when power is restored.

hope it works on our sump pump . Haven't had a outage yet

Didnt last too long at all!

This is the second one of these that I have purchased. Originally it was made by Noma and I got the first one at Canadian Tire about 7 years ago. I use it as a sump pump back-up. Living out of town, there are times when our power goes out, and during spring, we can't afford even an hour of electrical downtime. This device has saved our hides numerous times, as it keeps our 6 amp sump pump running for many hours during power outages. I would have given this item 5 stars, because it work well, but I tried to service my old one and could not get the parts that I required. Also I payed almost double for this model, even though it is exactly the same product as I purchased 7 years ago. All in all, very happy.

The battery hasn't been used as a back-up for about 2 months and since it was bought July 31st, 2017 and for that price, I expected it to last at least 6 or 7 years. I have used this avenue of complaint because I was unable to find any other way and to see if there is anything Amazon can do to rectify the situation as I have been manually draining the well of the sump pump myself when there has been a power cut. I am a 73 yr. old woman who has been recently widowed.

I use it for a backup power supply for my sump pump. I tested it and it lasted about 8-9 hours before needing recharging. I keep it plugged in at all times so that my sump pump operates in case of a power failure. This device is a "must have".
