Replace CyberPower 1500PFCLCD UPS Batteries

[@jayner2020]

Bought this device used with no battery for 25$ and got the batteries from amazon for 44. Thanks for this video on how to remove and install.

Watch out for corrosion on the battery, ate the anode connector.

[@Dragonubispwi]

I have the ExpertPower replacement and the cables do not aling correctly so i check plate with connectors have a - & + and i match those with the - & + from the battery. 2:56 you can also see the originals came with the blue cap wire connected to the red + and the black no cap with the - marks.

[@MourningLobster]

Thank you for this, and thank you for linking the right replacement for the right serial numbers. Much appreciated!

[@user-im2te2fg9y]

you just need a 12v 9ah battery with 6.35mm spade connectors often known as t2 or f2 oh and the battery dimensions have to fit inside the battery space. they don't need to be the exact same dimensions. just close enough to fit. you can also use 7ah or 8ah but you would lose run time, 12v 7ah is like 780 watts

Nice presentation. When I went to Amazon (official reseller for the OEM CyberPower batteries) to purchase replacement batteries for my 1500PFCLCD, it turned out the OEM CyberPower batteries for this unit were only $20 more than most of the 3rd party batteries. So, I decided to go with the OEM batteries for such a relatively small price difference. This was around Cyber Monday. Not sure if that made a difference as there were no "Cyber Monday Special" labels attached to the OEM battery. Anyway, I mention this for those folks who would prefer OEM batteries. Doesn't hurt to check the price differences of OEM vs.3rd party before hitting the "Purchase Button."

[@janovewaldner1]

Can I do it with just one battery instead of two? I don't need that much backup time, and I want to save some money.

[@Perplexer1]

Yep, it's that time for me as well. The video was done just in time. I'll be ordering my batteries tomorrow.

[@RobertVorthman]

Thanks! This video made it easy to replace the batteries in my UPS.

[@danleitner1635]

These batteries lasted about 1.5 years! Is it possible to upgrade to a better battery like a LiFePO4.

[@AnasSuhaimi]

Different chemistry, different charging/discharging parameter, you'll get in trouble if you do that.

[@brianbrockschmidt8951]

So if you have a new one. You could splice the plug and add extra batteries, correct?

[@sekaf4125]

Mine is doing2 beeps intermittently. Can’t figure out what that means. Thanks for the video

[@TimestampMusic]

I don't know how you managed to insert the new batteries in the UPS after the replacement. I tried to insert the new batteries in my UPS, with that plastic separator between them, and they wouldn't fit in the battery space no matter what, even though there was no empty space between the batteries and the separator. They had been placed perfectly. The only way I managed to insert them finally, was by removing that separator completely and just keeping the cables and the connector connected without it. Although the new batteries were 12V 9Ah SLA batteries too, it seems they were not exactly the same size as the original ones. I hope the cables are not in any danger now that the UPS operates without the battery separator and the upper battery is practically sitting on the connecting cables and we all know that both batteries get a bit hot inside the UPS. What's you opinion? Thanks.

[@jameshasanswers]

DId you order the same ExpertPower batteries linked in the description? Can you provide the measurements of each battery? As far as fitting them without the plastic separator, I think I'd only be concerned about the 'top' battery applying force to the battery terminals - not sure what sort of stress those can handle?

[@TimestampMusic]

@@jameshasanswers I haven't ordered the same batteries. I've been using CSB batteries for a long time, since the time I had bought my first UPS. I have used them with several UPS brands and I'm quite satisfied with them. I hadn't faced any size issues so far and I never thought there would be any. It seems Cyberpower is making the battery space in a way their own battery packs fit in exactly. They leave no slack for any slightly bigger batteries. I don't know why they make CSB batteries slightly bigger but they do. As long as the temperature doesn't have any impact on the connecting cables, like melting the insulations for example, since the temperature inside the room can reach up to 84°F during the summer months, I think the UPS should be fine. The pressure on the connectors seems to be OK. I can see they are in the same place so far.

[@Hoigwai]

Mine is completely dead. Went to power the PC and nothing, then checked connections, pressed power on the UPS, nothing, removed it from the loop plugged in the system normally and everything works. Plugged the UPS into another outlet and still nothing, unplugged, no beep, it seems to have died completely. Not even a year old and we didn't have any power events last night.

[@gregorymaddux3101]

Mine was completely dead, wouldn't do anything when I pressed the buttons. I tried unplugging the battery, and plugged the ups in without the battery connected, and it turned on. I'm assuming the battery shorted out. Replaced the battery, and good as new.

[@concerned_2023]

Can you buy larger than 9 amp/hr providing they fit?

[@jameshasanswers]

@@concerned_2023 as long as it's 12v, and of course fits like you said, then yep, should be fine

[@miguelv431]

so this ups run on 24 volt dc?

[@matronix1977]

How long do your original batteries lasted ? And new ones ? Thank you !

[@AlTheEngineer]

you're supposed to perform the UPS self-test every month or so and replace them when the self-test fails. Usually 3 to 4 years tops in residential use from my experience.

[@Smedley61]

Is three years about the life of the original batteries? Thanks.

[@jameshasanswers]

I don't have long term experience with SLA batteries in UPS's yet, but 1-3 years is what cyberpower themselves state on their website, so I'd say you're correct based on that! (www.cyberpower.com/in/en/knowledge/faq#:~:text=The%20battery%20lifespan%20depends%20on,years%20depending%20on%20environment%20conditions.)

[@VeniceInventors]

Mine finally gave up, which is how I ended up finding this video to figure out the right battery size, the original batteries lasted 9 years on mine. In all these years there only was a few instances of power failures that lasted long enough to require shutting down the computer before the batteries ran out, so I never completely drained the batteries, which might have helped them last longer. Now I'm considering getting LiFePo ones but the cheap HWE LifePo 12v 9A batteries I'm looking at only come with a 1 year warranty, which doesn't instill much confidence. [edit] and thinking about it, weight doesn't matter in a UPS so there might be no real benefits to using LiFePo instead of Lead-Acid.

[@Joyride149-1]

I agree with Veniceinventors. Hence why I am looking this up now. I bought it in November 2015 ($149, it goes on sale periodically) and it started giving me issues this year, I thought it was because I got a 1300 watt power supply. I can see from the Cyberpower software I do not pull more than 850w (not very often at that, mostly like 200). I can say the original batteries lasted way longer than expected and have served me well. I have only had ~ 3-4 shutdowns dues to power outage (I have my PC shutdown at like 40% battery (need enough juice to charge my phone in a major outage)), many more "brown outs" or 2-3min outages.

[@SimpTote]

My battery terminals did not want to be removed at aaaall. Videos make it look so easy to disconnect. Not sure why mine ended up being so stubborn.

[@MourningLobster]

Have replaced a bunch of ups batteries. The connector being really difficult to remove is very common. Feel free to use appropriate tools to gently nudge it from initial connection.

Talk to it with a gentle voice, whisper to it, it might listen to you.

[@gorazdvahen492]

Thank you, this was just what I needed! Saved me a bunch of time and money.

[@darwking8188]

Will these batteries work for the 1350PFCLCD model? I assume the main difference is the wattage on my dead unit is lower, but will it hurt putting in the larger batteries?

[@jameshasanswers]

the issue is that the batteries linked in the description will likely be a different phsyical size and won't fit -- the 1350PFCLCD uses 12v 7Ah batteries (per www.cyberpowersystems.com/product/ups/pfc-sinewave/cp1350pfclcd/) which have batteries that are stated to be different dimensions than that of the 1500PFCLCD official replacement batteries

[@Perplexer1]

@@jameshasanswers It's funny that 1500PFCLCD is stated to be using 12 V / 9 Ah batteries when the ones that are inside (at least in these old units with 2 USB-a ports) are actually 7 Ah (according to the PDF specs by B.B. Battery for HR1234W battery). Maybe the updated 1500PFCLCD (with USB-C on the front) uses a bigger battery as standard. I know the official battery pack model doesn't match with the old model (also has a different connector). EDIT: I just checked the spec sheet from 2012 when I bought my unit and back then they listed it as "12V 8.5AH x 2" which is at least a little bit closer to what's actually inside.

[@amber-fw2cm]

Great instructions. Thanks!

[@NeoEletto24]

Replaced batteries on my 1500PFCLCD and it doesn't last more than a couple of minutes at full load on my pc. The fun part is that if I put back the old batteries,they last more than 10 minutes at full load... Tried to swap batteries at the store,they gave me another couple,and every battery shows 12.7 volts,but exactly like the other two,they don't last more than two minutes. The ups display,rapidly decrease the battery percentage,if I disconnect it from the wall,but if I turn off my pc,it rapidly turns back to 60%... I don't know what to do...

[@gregorymaddux3101]

How long are you letting it charge before you put a load on it? It's supposed to charge a full 8 hours before you use it. What are the source of the batteries? There are some cheapo/counterfeit ones out there.

[@null8625]

were the batteries 9ah? they might have been a smaller size

[@Jacko49]

can you refill(RE JUICE) the battery like in a car system?is there acid,thanks

[@AmikoNovich]

Thanks a lot for the instruction!

[@BigEightiesNewWave]

Why would 12v batteries be in series to = 24 volts, on not increase capacity. Seem opposite of what a UPS is for.

[@AlTheEngineer]

Theoretically, UPS batteries can be used in parallel, but due to the individual differences of batteries, service life and other factors, it will not be easy to balance between batteries, which will affect the service life significantly. So wiring up in series is the easiest way. Voltage / Capacity doesn't really matter here because its all about the amp draw given the load when the UPS is active.

[@GGVicV]

I want to replace the SLA batteries for Lifepo4 when mine dies

[@jimmybrad156]

how old are your SLAs?

[@GGVicV]

@@jimmybrad156 about 4.5 years so it had a good run

Great video

[@NoEgg4u]

I find some screws to be unnecessary. The front panel of your CyberPower 1500PFCLCD looks like (and sounded like) the front cover snaps in place, making the screws an unnecessary chore. I have a 15 year old APC Smart UPS, and I leave the front cover loose, which makes battery replacement easier. I watched this video, because I have been researching CyberPower units, because I am fed up with APC. Although my old Smart UPS unit is fantastic, I purchased three additional APC units 3½ years ago. All three have had failures. My last failure was just beyond the warranty period, and APC refuses to replace the bad unit. Their quality control, even for their Smart UPS line, is noticeably worse than 10 or 15 years ago. Reading reviews, there was a common theme of cheapness, and issues. And APC's prices are quite high. Poor design, poor quality control, and raising the price, is a terrible formula. CyberPower gets very good reviews from customers, and are more affordable than APC, which is why I will be making a CyberPower UPS purchase. I was curious about battery swapping. It looks reasonably simple.
