I’m not sure if this is going to work out but I have an eBay "Yuasa” replacement battery, advertised as a replacement for APC.
Has anyone here done a battery replacement in a UPS? Is it easy or is it a nightmare? I’m not sure I’m going to be able to do it in bed, in which case this may have been a foolish idea. I was hoping you simply pop the new one in after somehow [?] getting in to access the old one?
What does one do about recycling the old one? I’m hoping I can send it back to APC?
-
Depends entirely on your UPS model, I've changed the batteries in our APC 1500 and they are very heavy for their size. I'm pretty sure we disposed off our old batteries in our own battery recycling bin, being a commercial workshop we get through a few truck batteries.
-
I have changed the batteries on my APC UPS many times, I find they only have a life of around 5 years or so in service. Its a little awkward as the batteries are heavy but very straight forward.
Just a comment, avoid buying on price, the really cheap batteries don't last at all, some I bought lasted less than a year.

It might be best for you to post the model number of your APC UPS and of the Yuassa battery you have obtained. (And, perhaps, links to images of them both.) I'm sure our UPS using experts will be able to confirm if the two are compatible.

@burakkucat - will do, Janet has her iPhone camera (and a ‘real’ camera too)
The eBay battery was in fact an amazon battery - I got my purchases mixed up. It so incredibly cheap that I didn’t have a lot to lose.
The advert says https://www.amazon.co.uk/RBC2-RBC17-Replacement-Battery-RBC/dp/B00SJKNNRA

I actually have two APC UPSs can’t remember the models : one is a black flat one with a couple of BS three pin mains sockets on the top; the other is the more familiar (to me) ‘tower’ type, with IEC C14 ‘kettle’-like (mistakenly so-called, by me :-[) sockets on the back.
I sorted out the assignments of everything the other day and now there’s only the Raspberry Pi on the black flat UPS and everything else is on the other one: main switch, firebrick, small mux switch and four modems. The WAPs each have their own Li-ion DC UPSs; I suppose I could PoE the WAPs from the main UPSs.
-
Impossible to say what models they are from your description, but my 1500 takes two of those batteries.
-
No, indeed. I will ask my beloved to take some pics when she emerges.
A question. How do I choose a device for longer battery runtime as opposed to W or A supply capability? It’s total Coulombs (or Joules if you prefer) that I want.
-
On APC's website, if you go to the technical specifications of a UPS, in the section Batteries & Runtime it has Battery Volt-Amp-Hour Capacity.
As a rough guide, they all are designed for a similar runtime, so the higher the number in the name of the model (which is the intended load), the larger the capacity and the longer runtime you will get if you are using a lower load.
-
Ah well spotted, thank you!

How does one physically get into a UPS?
I promised a photo of the UPSs; I forgot to nag poor Janet sufficiently, with her camera phone.

Unless you are Antman, I doubt anyone can :P
On a more serious note I suspect YouTube will have a guide once you know the make and model.
-
The APC models I've changed batteries in, the answer is "very easily" - if you read the manual.
-
I’ll dig around on YouTube then and I’ll have to find a manual somewhere; I didn’t realise that this was something that was covered as a customer replaceable thing. I’ll need some tools.
And ant man- there was a clunker if a movie. Is the second one as bad?

Just replaced the battery on my Trust (Oxxtrton) 1000VA UPS, used a Yucel Y9-12 (9AH) battery, diferent make, same spec. as original, cost approx. £28 + P&P from e-bay supplier.
Unit has been in service for just over 2 years, battery completely U/S., maintained minimal load for less than 30 sec's., could well have been U/S for some time earlier as never recently tested.
On re-commissioning, left case open with a 10 amp range Fluke multimeter in the battery circuit to check charging current.
Charging current tapered off nicely to expectation under no load from close to 1 amp to approx. 50 ma. over 8 hour period.
On load test with a 60 W. filiment lamp, close to 6.5 A's was drawn from the battery, obviously the inverter is not very efficient.
Load still going strong after 30 min's so aborted and re-boxed, happy with outcome.
Moral of the story, test UPS operation regularly, battery will eventually fail and certainly with my particular model will not be apparent until called into service, other, higher specification units may be different.

Old post I know but still relevant to my current input and not worth starting a new thread:
Just replaced my UPS battery again, not bad service I suppose, close to 4 years for a lead acid cell.
Tried to revive the disconnected battery with a smart charger, did manage to get the voltage back up to normal but collapsed again with minimal loading, end of life.
Got what I thought to be a battery replacement good deal from "Duracell Direct", competitive price with free courier next day delivery by DHL, by no means normal to my off-shore location, courier delivery usually heavily loaded to N.I.
Battery life with this particular cell, very reputable make, time will tell?
UPS backup is probably more important to me now as on FTTP with a digital phone LL.
Before anyone comments, my ONT is PoE powered, Hub & digital phone also UPS fed.
No big deal I know virtually everyone having access to a mobile phone these days.
As per previous post, important to periodically test the UPS health, I only discovered this failure during a short power outage.
-
Well this is new, I decided to replace my UPS with an identical model so I can swap the battery at my leisure rather than rushing.
Ordering the new one from Broadband Buyer I get presented with:
In line with the Consumer Law, namely ‘The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013’ you have 14 days to cancel your order.
Unfortunately, as your order contains 'special order' commercial products, we are unable to accept returns or cancellations for these goods.
Under the ICAC Regulations, you may waive your right to cancel the order, which would enable us to release your order to you.
Seems odd as I'd think these compact units with standard mains outlets on them are specifically designed for consumer use, not business.
