    Hi I am using a AT case with 350 watt powersuply and I added an 800watt inverter with 50Amp/h Battery the problem is that the battery never gets fully charged as rhe powersuply nominal voltage is 12v and the battery 13.8v there is no alternative powersuply that I can use in my area hense the thought to up the voltage on the powersuply Regards John

Hi John.
No idea why your post is under monitor problems ???
I figured you need an adapter mod for a monitor !! SO don't kill my ratings since this is not my area of expertise, but I can try to give you some input anyway, not so much a solution !!.
I would NOT recommend altering a 12 volt adapter for charging a battery especially if it is a standard ac adapter.. You may get it to give you 13.8, but your amps may be wrong.
Battery charger depends on type of battery also. Don't know if you are using NIMH or Nicad or acid based ?
The differnt style batteries use different type chargers. Wrong charger will burn up a battery or blow it up !!
If the battery is a 13.8 then normaly the charger would be putting out 2+- volts more than the battery rating. If you battery is 12 then a 13.8-14 would do the trick. (12 volt car batteries for instance take a 14+ volt source to charge them)
I would recommend looking here

They have all those goodies and may give you an idea. for what I think you are doing.

Can I recharge car battery with my stanley dps109 digital power station


charging voltage doesnt matter as much as charging current. what you need to know is that for a battery to charge properly it needs a feed of about 2.0amps over a period of 8-10hours (my recommendation) .
you need to establish whether your charger can provide a 12volt 2.0amp output.
take a look at this link, it very useful: Charging your car battery

Dear, Please check following

1. Are you using correct gauge of wire for batteries (Specification mentioned in the manual)
2. You need to charge your batteries at least for 8 hours (as recommended by Mercury)
3. Please place your Inverter in a cool environment (20 to 30 C)
4. Nominal voltage of battery should be 12Volt if using 1x Battery.

No Power (Totally Death).
  1. Check the output regulator 12volt DC Power Supply.
  2. Check the Fuse (Voltage Security Fuse).
  3. Check the Flexible cable on switch board (reset & eject button).
  4. Check the Output Diode.
  5. Or check the I/0 button.

Dear Sir/ Madam, I have TWO Western Digital USB


first of all , you are looking at the wrong voltages. The important voltage is the DC OUTPUT, which is the voltage the external harddrives use AND the polarity of the plug attached to the harddrive end of the cable.
if both the harddrives have say 12v dc output and both have the insignia of the center conductor being + (posative) then you can interchange them. and you CAN run a 9volt unit with 12volt DC power, but not the other way around.
Look at your power adaptors again for the OUTPUT and polarity.
should be a half-circle with lines depicting the polarity(+,-) of the center and sheild connections to the hard drives printed on both the harddrives and the power adaptors . This can also be tested with a dc volt meter while the adaptors are plugged into the wall.
DO NOT try to test the AC end while plugged in!!
Regards

Running but putting out power


You need to remove the cover where the outlets are at and measure the voltage before the breaker. There are no fuses on the output side of the genset only breakers. If breaker is fine but still no output, try flashing the fields with a 12 volt battery. If voltage increases then your voltage regulator is bad.

Generac model # 09734-1 no voltage output. would like a manual


Flash the fields. Remove front cover from the generator end. You will see the brushes and rings on the rotor. The ring closest to you is positive and the ring closest to the rotor windings is negative. With a 12 volt batttery and the generator running, place the positive side of the battery to the ring towards you and negative to the back ring. Make sure to use jumpers and keep fingers away from rotating parts and don't get zapped. You should see output voltage increase. If it does, your voltage regulator is bad, if it doesn't your generator end is bad.
