Question about QVS NetStar (UPS650A) UPS System

New battery will not recharge

I am having trouble with my NetStar UPS System despite having recently replaced the battery. The problem is that when it is not in use (turned off but plugged in wall outlet), it is unable to hold it's charge. However, if I leave it on, it is able to hold its charge and functions properly, e.g., during brownout, the computer will still function for a few minutes. The other problem is that once it is discharged, I am unable to properly charge it. The red light with the diagram X over a battery on the UPS panel remains constant on, while the green light also remains on. It usually takes about 2 or 3 days before it properly charges. And today has been the fifth day and the red light has not gone out. Appreciate any guidance.

Re: New battery will not recharge

Don't turn it off, the battery needs to be constantly charged or refreshed. They will go bad just sitting around with no voltage applied. The UPS draws very little power and has surge protection so there is very little to worry about.

How do i replace the battery on a netter xt 1200

Turn off power and unplug from the mains. Make sure the power button on the UPS is turned off. Remove the screws on the underside and remove the front cover. Pull the top part of the UPS upwards. Look for the battery connectors and remove the positive and negative cables from the battery. Install a new battery of the same value. Fix the positive cable first then the negative. Test it and close it up.

Hi Santhosh,

Have you checked to see if the batteries in the UPS are any good? Most UPS systems refuse to turn on if dead batteries are attached.

The problem will be in the battery in the unit. After 3 years the battery will be un chargeable the same as in the car. Batteries are available from most good battery shops . Take the unit in so that they can match it.

My PC is geting switch off when Power flatcutations come,even ups is connected and no back up comes from UPS, after that UPS takes >4 seconds to switch to mains supply.

A four second transfer time is way too long by at least an order of magnitude. There is no way the power supply in a PC can maintain for that long a time.

If you are in a real critical environment I would recommend going to a UPS which runs continuously and runs off a battery which is charged whenever utility power is available. That way there is no transfer time.
These offline units are harder to find however.

I suspect your UPS system is defective.

How to charge ups for pc's

Your PC connection must always come via UPS, and your UPS will always keep charging.

UPS Power cable should be connected to DC, and your PC power cable should be connected to UPS.

And this way your PC will always be safe.
