How do you know when to replace the battery?

Simplest answer: Replace it in 5 years if the system is working well, or less time if you are really dependent on it. Technical answer: Cyberpower claims an 8 Amp-hour capacity for that battery. It's not hard for a tech to open the case and independently test the battery. When well-charged, it should approach 8 AH at a 0.8 A discharge rate. If it does not, it may sometimes be renovated by a series of discharges and recharges at a higher rate. There is a hint here: The battery will be best conditioned if it is periodically discharged and recharged in use. Use the test that is suggested by the software and add a longer-term test occasionally.

Because it will no longer hold the charge of devices connected to it, when the power goes out. Also pretty much all of these units perform a self test on its own either once a week or month. If the unit starts beeping after the self test and the replace battery indicator is red, you will no its time.

When your house power goes off and your connected components turn off at the sametime usually your battery is dead.

I believe there is an indicator, but I honestly don't recall what it is, a light maybe. I knew mine had died because we had a long power outage(about a full day), and when the power came back on, the battery backup would not recharge. Still 5 years for a UPS is rather good. You can replace the internal batteries, but it is usually not that much more expensive to just by a new unit.

When the alarm signal goes off, and cannot be reset. Also, when this happens you have to buy a new unit. This just happened to me, so I can speak from experience. Good luck.

The rep at Cyberpower instructed me that the batteries have a typical shelf-life of about 3 years. I would presume that when your power-supplyied outlets stop functioning, that's when the battery has failed/died. Mine just happened to get hit by a power surge and hastened the process a little bit. I noticed this when the items plugged into the power-supplied outlets just stopped working, while items plugged into the regular surge-protected outlets continued to work (e.g., lamps, speakers, etc.)

We have not needed to replace the battery. I suggest you contact the manufacturer. Sorry I couldn't be more helpful.

You can use the battery replacement tool to find the right one you need. Additionally you can measure the L x W x H of your current battery and compare it to the suggestion from the tool.

If you mean when running on battery, the built-in display will give you estimated runtime based on connected active load. If you mean when will battery/ies need to be replaced, that can vary greatly anywhere between two years and much longer. Once a year for the first two years, unplug UPS and see if estimated runtime matches actual runtime - if close batteries are still good. After two years maybe start doing this test every 6 months or so.

I have had no need to replace the battery. I normally leave the unit on charge overnight. A side comment is it is worth the money.

Very easy...turn the device over..there is a round cap with a slot in it..place a coin in the slot..turn it counterclockwise..the cap will pop off.. pry the battery out taking notice which side of the battery is facing up..replace the new battery the same way.. replace the cap. It is a good idea to check the battery in both the sending and receiving units..I own 3 of these.. and 2 of them had weak old batteries rite out of the box.. I really like them.

I do not think the Battery is replacement and I did not check battery life.

If it is a new unit, try a different new battery (as the battery could be defective), followed by a different new unit.If it is an old unit, I would suspect it has failed (i.e. reached its lifetime, say over 5 years), and needs replacement.

Remove the Rubber protector (yellow color), you will find the battery compartment cover at the back, unscrew and replace the battery

I haven't had it long enough to replace the batteries. Generally, most electronic equipment holds information such as date / time for short periods when bateries are removed. If not, is easily reset through the menu sequence. Sorry unsble to be of more help. Tony

It varies, but usually, they tell you to replace any battery after one year or if you notice your items are not working as great - then it is time to change.

I haven't had any problems yet but would assume that if it's not the batteries, it probably needs to be replaced.

The battery is not replaceable. I haven't stressed the battery enough to reach any conclusions regarding its quality.

If,or when the battery goes dead. You will need the pull cord, until you can purchase a new battery.

I do not see any expiration date, but if the battery does not hold up well, then its time to replace it.

When you replace the battery then a setup about measure units to be shown appear. You can force this by removing the battery and put it back.

I have not had to change the battery yet. If you have a Batteries Plus in your area, I would suggest you take it there just to get their advice. That is what I will do.
