It sounds to me like you have a shorted cell in one of the batteries and the current limiting resistor on the charging side is out of tolerance (too low). Though it is more likely that they fail too high, they can go low in the event of overheating. I would check the resister with an ohm meter vs what is printed on it. It should usually be within 10 to 20% you can put one in series to limit the current, but you need a high current diode in parallel with it as no to limit the current to the inverter. I don't remember, but i think your model uses 2 12vdc batteries. You should replace all of its batteries and check the resister. Also, if there was a plastic insulator on the old mosfets you took off, you must have it on the new ones. this is to isolate the collector from ground. I home this helps,

My ups shuts down after ac power goes off


1. Open the UPS housing using a screwdriver.
2. Check the fuse. If is busted, have it replaced.
3. If the fuse is alright, check the battery terminal
for the stored voltage. It must be at least + or -
10% of the rated voltage of the battery. The rated
voltage is located at the battery. (12 volts). If the
voltage is below, 8 volts or only 30% of the rated
voltage. It must be replaced.
4. If the battery

I have to believe that the problem is in the smart chip, with the software that monitors the power. There is a very good chance that you have a slightly higher input voltage then normal. You may have to contact Powercom.....

I don't think you are in the USA...I sell Powercom and I don't recognize the part number. I think this is simular to the IMD 625 Va UPS sold here in the USA. The imperial model had a defect on the smart chip two years ago here in the USA, and I figured it out for the MFG, so maybe that same chip is acting up for you. Besides, the 600VA size should be too small for you know. You should upgrade to a 1000VA. It will handle the load much better.
