I have the above unit, it's 5 years old....a recent power outage appears to have caused the batteries to now not hold a charge...when plugged into a wall outlet, the the display tells me that the unit's charging CHg, but the amount shows 0 and no faults are displayed; although it does sound like it's heaving. Devices, when attached, become active, so power is obviously moving through the unit; however, when removed from the wall outlet, attached devices do not work. My thoughts are that the batteries are done and my question is whether they can be replaced (and how) because when I opened the case it appeared that the batteries were in a metal box and together with an motherboard attached on top did not allow the batteries to be easily removed/replaced. While it would be logical to assume that the batteries should be replaceable, often companies figure that units, batteries and everything else, should be trashed so that they can sell you another new unit. I would appreciate it if anyone has had experience with this unit and the issue of battery replacement...I called Customer Service about the status of the unit, but because of the age of the unit, I would have to speak with the manufacturer...I called the manufacturer, left a number and haven't heard from them yet...don't expect that I will.

 

A power outage is unlikely to have damaged the batteries. It is more likely to have damaged some part of the electronic circuitry.

 

I think this is probably the same unit and it states the batteries can be changed along with type?

Aren't they designed to take over during a power outage so damage to the circuitry is unlikely?

If this is the first time in some while there has been a power outage then it's more likely the batteries are at fault.

 

How old are the batteries? I am in IT, and if a UPS battery is more than three years old then we replace them. Because if there is a power outage, experience dictates that the batteries will not work. Some units have a test button that will tell if the battery has no more useful light. I am not familiar with your unit.

 

Gentlemen, first let me apologize for not doing a followup sooner. I do appreciate all your feedback and suggestions...good to know that " 'dem that knows" are here to share their knowledge and experiences with dummies like me.
I had gone to Total Battery with my problem; they attempted to correct the problem with installation of new batteries...it seems that the fix worked in their shop, but when I got it home, I was faced with the same original problem...I returned it to Total Battery (got full credit for the batteries with no restocking charge, but I let them keep the labour time charge) and we concluded that the problem must be the controlling circuitry, so the unit became scrap. I then purchased a 1200 Watt unit which, from what Total Battery determined, would give me about 3 hours of backup time on my 1/2 HP sump pump. While I would have liked more backup time, the price point for the unit seemed reasonable...it's now in my basement all charged up, running and tested. During my time looking for a solution I noted Canadian Tire had a mobile Eliminator Power Inverter (3000W) on sale for $240 (Reg. $400)...I thought that might be a solution, but then I realized I would need to buy 1 or 2 deep cycle batteries which would drive my total costs up considerably...any thoughts on whether I should have gone to the Power Inverter? Thanks.
