I have an old APC 1500w UPS that decided to die for Hurricane Milton.
It's been replaced by a newer CyberPower unit, so I've been ignoring it.
The little UPS in the garage went tits up, so I read some numbers off the old batt and ordered what I thought was the correct battery.
Nope.
But it was 1/2 of the batteries in the old 1500!
They're quite affordable, so I ordered another and what I think is the correct small battery for the little UPS.
With two batteries in hand I tried to replace them.
I untaped the spacer/plug thing from the old batteries and transferred it to the new ones.
And learned how fiddly it can be to get them just so and plugged in.
The first attempt was showing no battery.
But I left it plugged in for a while, thinking perhaps it would come back.
It didn't.
So I took out the new batteries and fiddled around with them until they would go into the hole the correct way. I was essentially trying to put them in rotated 180° because the alignment grooves will let you if one of the batteries is just a little off kilter.
Now it's showing a charge and acting all happy!
I've got a similar dual battery APC that I've also had to replace the batteries in a couple times. I also found it to be a little bit of a pain but also got mine working again. APC really wants you to buy a whole new UPS, and barring that their branded packaged replacement, but it is certainly much less expensive to do it the way you did. Last time I replaced the batteries it was about 1/2 the price do but the two batteries and re-use the spacer and wiring harness/connector vs the APC branded replacement.
