How long can this battery last for a laptop that draws 200W, 9.2a and 19.5 volts? Any recommendation of type (or brand) of sine inverter/charger?Thks!

I had done a solar test with $5000 and had bought three of these batteries and 6 German 158 watt panels and the batteries did not hold enough charge to cater to one room with light and computer and laptop. I used a Cobra CPI 2575 and Ramsond Sunshine Pro. The batteries look good and one can decorate a living room with it!

Theoretically 125 ah/9.2 amps x 19.5v/12v hours. However, you should never draw a battery below about 50%, so divide that by 2 . There are also efficiency losses. You are looking at something over 6 hours. If you draw the battery to 0 you will destroy the battery much more quickly. I use AIMS pure sine wave converters available from them or Amazon. American made quality. Keep the battery charged when not being used.

I used the 200w report solar panel system to charge that batt. 3 of us ran laptops and phones as well as a heavy water pump and the solar panel kept it full almost always. Did this for 17 days. I'm not sure how much AGM batteries are meant to deep cycle though so look into that.

I used a Xantrex brand 1000W modified sine wave unit and it works just fine. I used #2 battery cables about 3ft long each that I custom made between the battery and the inverter. I got #2 welding cable from a local hardware supply store and the cable lugs from an electrical wholesale supply house. I used solder paste on the wire and using a propane torch and plumbing solder I soldered the copper cable into the cable lugs. I also installed a 100A fuse on the 12V side for safety. For the battery I used a Trojan 27TMX deep cycle battery. I you need photos of my setup I can send you them.

My Anker battery also died within a year. I can now only run my laptop on battery power for 15 minutes. Wish I would have spent the extra money an bought the HP OEM battery. The old saying is true - you get what you pay for!!

The max wattage that the system has is 5000 watt peak and 2500 watt continuous. That is the power that it can handle from the appliances/items that you want to run. The battery bank consists of (2)100ah batteries which provides a total of 2400 watt hours. You can add more batteries to the system to extend the run time. The pure sine wave inverter is $200 extra. Thanks

The spec sheet (http://www.cyberpowersystems.com/products/ups-systems/pfc-sinewave-series/CP1500PFCLCD.html?selectedTabId=specifications&imageI=#tab-box) says the battery is 8.5AH @ 12V, so 102WH (Watt Hours). Arbitrarily say that you can convert from battery to AC at 85% efficiency, so you have about 86WH. 86WH / 120W = about 0.72H, or 40 minutes, best case. I couldn't find specs on the max wattage allowed per power outlet, but I doubt that the limit is 120W...

I don't know the answer as it is my main battery for my laptop. I just use it till it runs out of power and then plug the power cord back into the 'puter. It's still good for 3 hours continuous use. When I bought this battery, also upgraded the memory and it was a cheap solution to buying a whole new laptop

Practically any power inverter will power this laptop. http://www.amazon.com/Kinivo-CCA150-Power-Inverter-Charging/dp/B008YMUQI2/ref=sr_1_28?ie=UTF8&qid=1389488568&sr=8-28&keywords=power+inverter

Saul,The battery lasts quite a long time depending on settings and how you have it set up. I have mine set up for High performance when plugged in, but when I put it on battery it goes into a light power mode which lasts for about 4 hours being that I am usually running several windows of word, excel, and multiple Java programming windows. If you are looking to get a gaming laptop with a high performance battery I would have to say this would be one of the top choices for a 17" laptop.

Purchased mine in 2011 and it's still going strong. We'll over 3.5 hours with nothing running and over 2.5 hours with active aplications. I learned with IBM & Lenovo laptops you can't keep charging their batteries. When they are fully charged unplug and when low recharge and so on.

Good Morning, In a quick check of D620 power requirements(19.5vdc@4.62a), I would say that you should not use this charger. It is rated at only 65w vise the 90w requirement for the computer. Would look for another charger that has the correct rating. Best luck Andy

Hi Brian this Thinkpad Battery 19 6 Cell piggy back like tray attached underneath or docked on battery you have plus this last up to 15 hrs I use it most of time on hi performance setting run min of 9hrs great device it make it a little heavier it extend the battery by 2.5 times .if you by $78 one it like original battery you have to change it with recharge one .I am very happy with it because I use it for photo editing adobe CS5 and adobe premium my hoppy photography I custom build Hi performance gaming machine for business application. I hope this answer your question about extend battery. Good Luck. Best regard Hossein Lavi

The short answer is "Yes". David Tullos says it will last 8 - 10 hours on full load (1500 watts) but I do not believe it will last any where near that long. The first link I have provided below computes the battery will last .66 hours at a continuous 1500 watt load and that makes sense to me. I have run a 2500 watt inverter on 1 of these 12 volt 100 amp hour batteries. The inverter must be a 12 volt inverter. The question is...how long will the battery last. That depends on the average (a refrigerator for example) or continuous wattage (maybe a 1500 watt heater running continuously) used by the electrical devices being powered. Of course the fridge doesn't run continuously so you have to take that into account. If you run a 1500 watt heater continuously off of this 100 amp hour battery you should be able to compute how long it will last. You also do not want to discharge the battery too much below 50%. There is a certain amount of research you need to do part of which involves using very thick gauge (probably at least 4 awg but maybe as large as 0 awg) cables from the inverter to the battery which your inverter documentation should tell you. The general rule of thumb for DC current is that for every 1 amp of AC current used by an appliance you will draw 10 amps of DC current from the battery. 10 amps of AC current will draw about 100 amps of DC current. Here are some links that might help. I do not know how reliable these are but they seem to be correct with my understanding of electricity and the research I've done. The first link seems to be the simplest to use by plugging in your own data. http://usasolarwind.com/Tools/BET.html http://powerstuff.co.za/battery-size-calculator/ http://www.bdbatteries.com/dcdcsolar.php I hope this helps.

The "pure sine wave" inverter can help running some things and eliminate a sound "Buzz" that can come from the cheaper "modified sine wave" inverters running radios & such. However, I'm not sure for a laptop that it will make that big a difference since the power is converted back to DC anyway (where it almost seems funny to take DC power, change it to AC just to go back to DC).

If you are looking for an External battery charger, then I went ahead and bought this: External Battery Charger for Dell Inspiron 1525, 1526, 1545 Series Laptop BatterySold by Top Power The first one that came was damaged but it only took a matter of an email and a phone call before they sent me a brand new one- no shipping fee incurred on my behalf. Its a great battery- I just ordered another 9 cell to charge while the other one is in use. Hope this was relevant

...the unit charges at 18.5 volts.....as long your device being powered is less than 18.5 volts, the unit will charge itself and provide power via the usb or dc.....I'm doing it right now with this laptop I'm using....the powerbrick died on this laptop.....this laptop uses 12 volts so, the Poweradd can reasonably provide output to the laptop and charge itself at the same time.......I have another laptop that is 19 volts and the unit continually depleted while plugged in to the wall to charge.....but it still provided power to the laptop....
