Is it runtime that you are having a problem maintaining? If you are looking for 12 hours on battery you will need a bigger UPS - or one that you can add more battery compartments to... Your current UPS just won't do it... and be careful about connecting multiple batteries to 1 UPS - you may just blow the invertor in the UPS.

How many 12v batteries are needed to run a 15000w inverter properly


It is normal to use only half of the capacity of a battery and this is called 50% depth of discharge (DOD) so the watts of a battery is volt X amp hours eg a 12 volt bat @ 200 AH would be 2400 watts but you can only use half of that other wise the battery will be stuffed, so all you have is 1200 watts, if you have a 400 AH battery you would have 2400 watts, you also have to know the capacity of the battery and this is call the C rating of the battery once you have that you can work out how many hours it will run for.
On an of grid system I would not use any less than 6oo to 700 AH @ C100
It is normal to size the batters to energy demand in KWHrs per day of (AC load )
Hope this help.

There is no TV button to press on rc-017 remote, setup instructions say press on tv button till led lights up.


If you mean the Coby RC-017 remote, it is not a universal remote that can be set to control any TV or other device. This remote will only work with the TV for which it was originally programmed. I believe it should work for a TF-TV1511, if both the remote transmitter and television IR sensor are working. Assuming you have the correct TV, try just pressing the power button.

I hope this helps.

Acer Aspire 4830T battery issue - Laptop shutting down abruptly though the battery shows 90% charge available.


Did you follow the initial charging instructions that came with the battery from the manufacturer? Does the battery fit properly and is not loose or gets loose during use/moving around? Are the cooling fans under the unit all clean, clear, unobstructed and working properly? Is the battery of the same type as the original? You can't always replace a Cadmium with NImh etc, the charger may not be compatible and give you erroneous indications and poor charging performance and may damage the battery.

No Power


Your laptop's power jack may be broken, which is why your laptop doesn't charge your battery at all, which is why it won't turn on now. I would take a look to make sure that the power supply is good, the battery is good, and then see if the power LED is even coming on when you plug the laptop to a power source.

Dell Vostro Battery charging problems


Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then -The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty.Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced.If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard.This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

How do you check the battery status?


Check battery voltage using Volt meter=> it should be about 12.6 to 13.8 vdc.
Pull the battery out... checking the deforming at the case ..such as "swelling"... if yes .. replace the battery.
Replacement battery is about 10-20 dollars on e-bay (watch for shipping charge and size. and terminal connection sizes )
The average life of battery on UPS is about 5-7-10 years wi)th UPS plugged in (Charging
One I had my local Autozone checked my 12 VDC -8 AH ... ask them to set CCA at about 100 AMP...
for 12 VDC -14 AH ask them to set CCA about 200 AMP.
For a 12 VDC -75 AH (group 24) they set the load on their tester at about 700-900 CCA.
You can also buy a manual battery load test at Harror freigt tool for about $20 US dollars (On sale)

Check your mains adapter plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.

If the adapter is OK then connect it to the laptop power it up then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. I suggest you get a quote first.

I have a compaq presario 700 laptop that is no longer charging.


The notebook battery may have a defect if it will not power on the notebook and if it will not hold a charge. The battery indicator light on the notebook either does not light or always blinks orange. The notebook operates correctly when connected to the AC adapter.
A battery that will not charge may be the result of an AC adapter failure, a system board failure, or a battery failure. Perform the steps below to diagnose the failure.
Troubleshoot the power supply
To verify that the AC power supply is functioning properly, follow the steps below.

1.
Plug the AC adapter directly into a functioning wall outlet, and plug connector into the computer. Do not plug into a power strip, surge protector or secondary power source.
2.
Verify the following operation and take the appropriate action:
*
That all power cord connections are secure.
If the AC adapter connection to the notebook is loose, the connector may be damaged and require repair. Contact HP service and support for further assistance.
*
That the power button or power LED is lit when the computer is on.
*
That an LED on the AC power supply adapter is lit when plugged into an AC wall outlet (not available on all AC power supply adapters).
*
That the AC power supply adapter is the correct type.
Different notebook models require different AC power supply adapters. You will need to know the Product Number of your notebook to determine the Part Number of the replacement part. Click Start > HP Help & Support to view the product name, product number, and serial number that you'll need to have to speak with HP Customer Service.
View the See Also section for information about locating HP Help & Support in your operating system.

Troubleshoot the System Board
If you've verified that the AC power functions properly, troubleshoot the PC's system board by following the steps below.

1.
Remove the battery, and keep the notebook connected to AC power.
2.
Press and release the Power button to start the computer.
*
If the notebook PC powers on , then the AC adapter and system board are functioning properly. Go to Troubleshoot the battery .
*
If the Power LED is off , then the AC power adapter needs to be replaced. Contact HP Service and Support for further assistance.
*
If the power LED is on , but the notebook PC does not power on, then the notebook PC needs to be repaired. Contact HP Service and Support for further assistance.
3.
Shut down Windows by selecting Shut Down from the Start Menu.

Troubleshoot the battery
If you have verified the AC power supply and system board are functioning correctly, troubleshoot the battery by following the steps below.

1.
Insert the battery into the battery compartment on the bottom of the notebook PC.
2.
Connect the AC power supply and allow the battery to charge for 15 to 30 minutes.
NOTE: The Battery Charging light should be on while the battery is charging. If it is not on, check the AC power adapter connection to the notebook PC.
3.
Unplug the AC power adapter cord from the notebook PC.
4.
Press and release the Power button to start the computer using only the battery as the power source.
*
If the PC does not power on, then the battery needs to be replaced. Contact HP service and support for further assistance.
*
If the notebook PC does power on, the battery is functioning properly.
NOTE: If you have purchased a second battery for your notebook PC or you have access to an identical battery, you can also check the battery by inserting the second battery into the PC and performing the Troubleshoot the battery steps again.
