I have one of these. When the batteries are fully charged according to voltage, this monitor still shows SOC at ~60%. What am I doing wrong?

Even though the battery voltage is reading 13.5 volts, it does not mean the batteries are fully charged. Fully charged should read 14.2 volts, that is when the soc will read full but only if there is no load on the batteries

I am not sure why it does it, but mine does it occasionally also. One thing you can check is to see what Amp hour you have it set for, It seems that when mine shows that I have had the Ah set wrong and it is showing that because I have had it set to a higher Ah battery than what I actually had. The battery will only take so many amps before the resistance gets too high and charge shuts off. If you have a 100 Ah batter and have the meter set to 200 Ah, The meter will show half full when the battery is full and the charge shuts off or goes into float mode from the controller. That is where I would look first. Make sure that you have the meter set right with the battery you have and then if it still shows 60%SOC you may have a bad one. But After I changed my settings, the meter seems to be reading correctly. It has actually gone to 100% Hope that works for you!

If battery voltage reading is 13 to 13.5 this does not mean that the batteries are fully charged. Fully charged is around 14.2 volts at which point the SOC will read 100% but there must be no load on the batteries. Hope this helps.

I have the same issue. Not sure what is going on. Tried full charge with no load. Only time I would have 100 percent is when the charger is hooked up.

Fully charged agm battery will be around 12.9V. My mppt charge controller blinks when battery charge goes 13.4 and after 1 hour stand by it will go 12.9 V which is sate of full charge (confirmed with Concorde sun xtender rep). But for some reason mt-5 shows 50% and it is wrong. I will find out with monitor manufacturer and update later.

Actually I will be firing my system up this weekend (3-2-13). I can let you know.

I think they all do that. I have a separate battery monitor Trimetric. You really need a shunt on the battery negative for an accurate SOC state of charge. The MT-5 provides info about the current going in and out of the charge controller

I just spoke with an Avent representative and they told me that the display going bad is definitely not a battery issue. Battery issues involve the monitor going dead or starting to go dead. I called them with the same display problem (we've had our monitor for just over two years) and they're going to send me a replacement monitor (and we're sending our old one back). Hope that helps!

LCD screens take such an infinitesimally small amount of battery current that it's not a factor in battery life at all. Mine is working fine, as opposed to the timers that a couple of other people here indicated.

I assume that you replaced both batteries and your unit is a APC BACK-UPS XS 1300VA, with AMD board, 1 AMD 4-core cpu, on-board graphics and Samsung 27" (?) monitor, I am drawing 90 watts total and the UPS says I have 52 minutes estimated run-time after 3 months of service. Same as new. You may have a bad battery but do as the first person suggested, try a reset. In a UPS you always replace all the batteries when it is time - hope this helps

I have one on a P2770FH that is not working very well. My OEM is rated at 14VDC and 3.5 amps. This power supply is rated for 3amps and my monitor turns off after less than an hour of use. I have to wait for a little while and then I can turn it on again. It maybe my monitor and not the power supply. I am going to order another power supply with higher amp rating and see if it will stay on.

I was able to use this with a 7.2v battery running at 2.2 amps, are you sure the video feed is working? if it is then you must have a faulty screen.

I am not familiar with that reading. My unit has worked like a charm. I would suggest that you go to the vendor's website. Maybe someone else has experienced something similar. Good luck!

I'm getting about 3hrs of continuous movie play at full brightness on mine. I didn't get a "service battery" alert although the old and tired original one did. Make sure you "calibrate" the system for the battery. Do a search for macbook battery calibration

The LED for each port should be illuminated when charging at its full rate. As it approaches the battery's full charge, the LED should blink. The rate of blinking will diminish; when the battery is fully charged, blinking will stop - or blink only very occasionally.If your charger doesn't operate this way, it isn't operating as it should.

With the controller saying a 100% SOC my meter is matching the controllers number at 13.7.

I have to replace my battery on average of once a month. The monitor gets used 90 minutes a day on average. This seems high to me. Not sure what other monitors performance is.

It is showing this because the battery is third party and not supported. Mine does the same thing and I'll be returning it.

Try running something not as power demanding and see if it works. Do you have a multimeter? What type/capacity battery is it? How are you charging the battery?

I've run the LCD attached to the controller with both 12 v and 5 v and it shouldn't have a problem running from battery - I'm in the process of converting mine to battery now. I found this online for specs - http://www.panelook.com/AT070TN90_Innolux_7.0_CELL_parameter_13533.html (It shows the panel takes 3.3-10.4V around 20 mA). I found this for the controller: http://www.vslcd.com/Specification/VS-TY2662-V1.pdf. It shows that the controller takes 12 v, but I've run it with 5 v from a USB wall wart. Hope this helps.

On mine the LED display stays on while charging too. I found that a bit weird aswell.

You may simply need to recalibrate the battery charging on the macbook. If you were using an old battery, and then switched to a new one, the charge percentages may not be accurate. If you google battery calibration macbook you will get some helpful information on how to do it.
