When can you tell if the batteries need to be replaced?

Software runs in the system tray that will allow you to periodically "self test" the battery. I do this on a monthly basis.

It has a battery gauge on the display and you can perform a self-test on it. I assume it would tell you after the self-test that it doesn't have the expected capacity.

Hi,Theoretically, good SLA batteries life time would be around 3-4 years, if UPS system is not frequently discharging/charging batteries. On the display you can see battery's charge level. When level is not on "max" and stays this way no matter, how long is charged - it could be good signal to replace battery. In my application I replaced battery with external block of four original batteries connected parallel because I needed more power to be delivered with long period of the time.

The directions say to replace the batteries (it takes 3 AA batteries which are included) once a year. It will give an audible and display signal when the batteries need to be replaced also.

Does that when batteries are dead. If they.re fresh batteries, then it.s prolly the type of battery.

As far as I can tell when the batteries quit recharging is the the expiration date.

They should be recharged. These batteries may be recharged many times if they are used properly and not left on until they are completely dead.

Murphys law it happens in the middle of the night. If you always change the battery when the clocks get changed for daylights savings time this won't catch you off guard. If it's a few years old and keeps going off it may need a replacement.

I replaced them once. I purchased a pack of replacement batteries on Amazon.

I don't know. I would probably pull batteries out and replace if it doesn't show correctly.

Check if your batteries are in the right position. Positive (+) and negative (-)contacts Check the expiration date in the batteries carton, use a good brand as DuracellCheck minside the batteries compartament for a broque contact

You are lucky. Mine didn't last long enough to need new batteries. It was a complete waste of money. Sorry I couldn't help.

I'm sorry I don't know. I haven't had to replace it. If you take it to a battery place they can tell you when they replace it.

Gee, I'm sorry to hear of your problems. Mine came "ready to go" and I've yet to need to replace the batteries. If you received the wrong batteries for the unit, I suggest you contact Amazon. They are quick to resolve any problems I have ever had. Good luck.

It needs it's battery replaced. Make sure you check it to see if it still works after you replace the batteries though; sometimes mine have needed to be reset after.

We have had six of these units in our home for over a year. We replaced all batteries after approximately one year. One unit is outside in the cold and heat and it's batteries lasted a year. The unit will give a little chime note every three or four minutes when the batteries need to be replaced.

I purchased mine a little over a year ago and have not had to change the batteries yet.

I'm not sure I understand the question. Do you mean on a new set of batteries?

Most likely you will need to replace the battery for the same reasons stated by the others.
