Replace CyberPower 1500PFCLCD UPS Batteries

Learn how to replace the battery(s) in a CyberPower 1500PFCLCD (CP1500PFCLCD) UPS. Basically, it's as simple as removing two screws, sliding off apanel, removing a connector, pulling out the battery(s), and then doing it in reverse.
You have two options for sourcing the batteries:
1) The official CyberPower branded replacement:
* If your serial number starts with CXX: amzn.to/4ddnbRm
* Or if it starts with CR9, CXF, or CQC: amzn.to/49QdIwb. These are typically twice as expensive as buying non-CyberPower branded batteries.
2) Aftermarket (non-CyberPower brand) replacement: amzn.to/4dbvQUg (you need two of these, and then you reuse the tape and connectors from the original battery). Note that you basically just need two 12v 9Ah SLA (sealed lead acid) batteries, which there are many brands to choose from; I've simply had good luck using the ExpertPower EXP1290's (linked above) in the past, so I continue to use them.

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

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.

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...

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

@@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.

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

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