I was wondering why no one mentions whether batteries are installed in series or parallel. Thank you for mentioning this important detail. My UPS is back up and running after several years.
@@KentuckyRanger Actually it is the other way around. If connected in series, the U sums up and you get 24 V and the same amperes (9Ah). In parallel you get the same U=12V and the amperes sum up (18Ah). In UPS it is recommended to use series connections to protect batteries (not all are the same). In II they will decalibrate, the weaker one will discharge the better one. Hope it helps.
I was about ready to get a new battery because I noticed that mine was not holding a charge after 8 years. This will save me money. So, I'm grateful for your careful and well-explained video.
Thank you very much for posting this. I spran for the cyber power battery replacements, which was a mistake. I paid almost twice as much for 0EM batteries. I should’ve gone for the low cost spread. The cyber power replacements do not come with the adhesive tape pulltabs that are on the originals. Somehow all mine were sticky enough that I had to destroy them and taking the batteries out of the unit. you would think for the price the cyber power could afford to include a new piece of tape. The instructions to come with a cyber power replacement batteries cram replacement instructions for every kind of cyber power unit ever made. Not only are they microscopic but they are very poorly written. Thanks again for your post on UA-cam.
Thank you so much for posting this! There was another video, but it was with Cyberpower branded batteries, which was useless because they don't make them anymore! This was exactly what I needed. 👍🏻
Good video! Thank you for sharing. They do make lithium battery replacement which have +2000 cycles but they cost about $190 for 2 of them but are 1/3 the weight. They might last for 20 years or more.
I would not put a large Lithium-Ion battery pack inside my home. Just Google: "e-scooter fire at home/elevator" ua-cam.com/video/HBUGEFErXxA/v-deo.html Just saying... ¯\_(ツ)_/¯
@@eliasb8 thanks. Just replaced mine successfully, but I had different ups 1500epfclcd, and was totally disappointed for glue in the frame, that join both batteries. Also disconnecting that connectors on batteries was challenge, as one of these was sitting so hard, that I needed to use tools to get it off. Later, when trying to put battery pack inside it was impossible to join them perfectly flat, as that frame had cable tunnels , and cables was stiff. I hope it will work as long as possible.
@VLAD_8011 the worst part is over. Lead acid battery quemistry is pretty much the same everywhere, so your battery should last as much as a new battery from the manufacturer of your UPS.
A company has just released a few months ago a lithium battery with solid electrolyte commercially. These batteries are much safer and I would be confident to put them inside my house. The regular lithium batteries are too scary to use at home.
I got one of these for $20 used! But... Of course it doesn't turn on at all. The batteries read absolutely 0 volts each which is surprising there's not even 0.01v.. do you think dead dead batteries will keep it from turning on at all or did I buy junk?
Hard to say. If I remember well, my device jusy died! The display didn't show anything. You could buy the batteries from Amazon. If it doesn't work, you could always return the batteries.
@@eliasb8 after an hour on a battery tender one battery charged to 4.3v, the other battery read faulty by the battery tender. I put them both back in my cp1500av and it did actually turn on for about 5 seconds before going back to a blue flashing screen. What little info I did see on the screen was completely wrong battery information. I ordered new fresh batteries confident that it will revive this unit (hopefully!). Should be here tomorrow. I'll update my report when I get them installed. New Batteries were $50 so $70 total is a great deal for when I was expecting to have to spend prob around $250 for my needs.
Yes success! New Batteries bought my $20 1500av to life! Can't wait for my first power outage 🤣 actually all the power in my area is underground buried lines so it rarely goes out for extended times but once or twice a week I would hear my old APC kick in for a second or two for a brown out. My old one is 7 years old so time to give it a heart transplant and move it to a different part of the house.
they very good but battery life not that good ok you buy 2000 watts inverter you buy 4 12V 30amp 10000 deep cycle battery with BMS 30 amp 384 watts you spend $1,300 ok get 4 battery last much longer ok

You are the first uploader who stated the two batteries are connected in series! I’ve been searching for hours. Thank you!
It was my pleasure!

It’s VERY important, that they’re connected in series. If connected in parallel, you’d ruin the UPS, by introducing 24 volts into the system.

Thanks for the video. I have the same unit and being able to see someone else swap the batteries before I tried it myself made it very easy!
My pleasure! 😊👍
Great video, thank you SO much. For $45 I got my unit back up and running after it had died. Much appreciated!

Than you for the great demonstration, helped a lot.
Bout to replace the batteries in one of my UPS's now. Thanks for the info bud!
Thanks for the video, I followed the steps and it's working fine!
This is an excellent tutorial. Thanks!!!
gracias a este video ahorre dinero, ya no compre uno nuevo.
Thank you! Now I know how to service my trusty unit should it become necessary! 🇺🇸 😎👍☕
Good to hear that! 😊👍
Excellent guide; I just did mine. Wiring the two batteries was pretty nerve-wracking for a moment.

Thank you! Super useful! God bless 🙏🏻
God bless you too!!

Amazing video, thanks
Just a tiny bit of hyperbole but I love it!! 😁
Great video! Please share the link for the Amazon batteries
As I said on the video, the links are in the description.
Thank you!
You are welcome!
😊👍
Is there any safety order, of connecting red and black cables?
Not really. The only thing that you should try to avoid at all cost is a short circuit because the batteries come with a charge.

Think you could just use a LiFePo4 12V/9Ah battery instead of a lead acid one? I was wondering this myself, but I am not sure it's "safe" to do.

Looks like I get a blue flashing display when I power it in without the batteries installed so I'm guessing the batteries are preventing turn on.

I just hope that this expensive device doesn't end up in a landfill.

It sounds like a great project if you have the disposable income and the extra room next to your PC! 🙂👍
