Antibiotika224

Thank you for the reply That is not the same unit I have but maybe an older model Anyways Yes I know it is not made for prolonged use and this is because of Overheating, and fixing the overheating issue it will run for prolonged periods as stated in my post I am also on a tight budget, that is why I am not buying another inverter because that would double my budget That being said I need advice on the last part I am going to replace the UPS eventually with a Proper Inverter later on IE I want to connect the batteries to the UPS with a diode/s to stop the built-in charger from giving power to the batteries And then a diode from the batteries to the external charger to stop power from going back into the charger The above is so that I can avoid having to unplug batteries charge and then replug them like suggested in other forums and such Will this work? So that I do not have to unplug the batteries, and can just keep it as a standalone low maintenance unit Or must I rather add something like brad harrison connectors to the batteries unplug them to charge and then replug them after charging Or will this cause more voltage to go intot he UPS from the charger being permanently connected And not advice on the UPS etc.

Hi I need some guidance whether my plan is feasible Okay some details before hand I have a RCT 2000VA UPS , and the batteries(2 x 12v 7.2ah in series) are dead I am planning on replacing the batteries With 2 x 12v 50ah batteries Now I know the built in charger is too weak to charge them By my calculations and other posts in this thread, it will take 2-3 days to charge them from empty on the built in charger I will also add more cooling to avoid the overheating, maybe a heatsink and a few fans To The Actual question now So I am planning on getting an external charger, solar or Eskom to charge the batteries What I need guidance with I want to connect the batteries to the UPS with a diode/s to stop the built-in charger from giving power to the batteries And then a diode from the batteries to the external charger to stop power from going back into the charger The above is so that I can avoid having to unplug batteries charge and then replug them like suggested in other forums and such Will this work?
