no you cannot. Li-Ion chemistry aren't close enough to SLA, you'll either be too low or too high voltage. Charging profile are also very different. LiFePo on the other hand, can.
As far as I know the LiFePo just have a built in circuit to regulate the charging voltage, which is the only reason they're "more" compatible. However the charging "profile" of the UPS is totally different for SLA vs Li so it still won't be ideal and will shorten the life of those LiPo/LiFePo batts.

I've been buying 'generic' ones off EBay, and they run for ~5 years, which is in line with the lifespan I got out of the OE batteries that came with my APC UPSes.
The couple times I tried and the couple times people I know tried, not only did they only get much less runtime to start, but the runtime degraded very quickly. What kind of runtime do you get after 5 years?

Might be stupid question but say you buy 2 of them. Then you charge each of them. If you have a spare one, and then run out of power with the regular battery backup on the UPS, could you take your backup ups battery which you already charged a while back and it would work? Or battery would most likely be out? So you need to make sure you charge each of them once every 2 weeks or so?


Also I don't have APS but cyberpower but are these easy to install? What tools do you need?
It's probably not the best idea but, if the UPS supports "cold start" it would probably work. The battery gauge will probably be completely inaccurate, since it won't have a way of determining the actual charge level. While it used to be extremely common, the cold start feature seems to be disappearing or becoming more limited. My recent Cyber Power UPS will only cold start if it knows the battery is fully charged, so it would not work in this situation. I believe the reason for this is so that they don't have to ship the UPS with the battery disconnected.

By the way, you likely wouldn't have to charge the battery every 2 weeks. In my experience, under normal conditions (no extreme temperatures, etc.) SLA batteries tend to be pretty good at holding their charge. The ones I let sit probably only get topped off a couple times a year and it usually only takes a few minutes for them to reach full charge.

You're not wrong, but you're also incorrect as this has been done. The bms takes care of regulation for you. Go YouTube it out Google it.
The BMS limits the voltage, but unless you're getting a really good/expensive one specifically designed for this purpopse, it isn't going to convert the charging profile of the UPS to match what Lithium wants.

Also need to be cautious about the drain when you switch to battery, if your UPS is heavily loaded you may very easily exceed the rating of those Lithium batteries. Could either mean you lose power briefly during the switch, or you cook the batteries and have a dangerous condition.

Yes it can be done, but personally I wouldn't recommend it.

Heck you can hook up a bunch of deep cycle batteries to your UPS and put them in a "battery box" but you risk toxic gasses being released. The battery box is there in case the batteries explode - which in and of itself says "not a good idea".

This deal isn't really that hot, unless you really want that APC sticker. If you need this, I'd just keep an eye out for a good price ($20-30) on a genuine CSB HR1234WF2 or CSB UPS12460F2. The former is often what you'll find under this APC sticker. I think the latter is just an ever so slightly better version. They're interchangeable. These are quality batteries and will likely last much longer than those cheap ones like Mighty Max (which I haven't actually tried) and so on.




I've never heard of anyone doing this. Do you have any links? This sounds extremely dangerous. I think you'd need some seriously beefy circuitry to regulate charging and discharging. In a UPS, batteries like these could have a current draw in excess of 40 amps. That doesn't even get into the fact that a UPS charges in a way that is totally unacceptable for Li-Ion cells.




Where did you guys find LiFePO4 batteries that are compatible with a UPS? While I've seen plenty in the correct form factor, I've yet to come across one that claims to be usable in this application.
Heh all the same points I was making didn't realize you were making them first.

I only use CSB - as you say most APC batteries are CSB under the sticker (occasionally have seen panasonic in older ones). CSB actually has a Long Life version now (HRL) for some batteries (from what I recall the 1234 is one of them), and I've been using those. Rated for 7 years or more in UPS applications that aren't discharged frequently. The standard CSBs I can get 5-8 years out of easily (still at 80% or more of capacity), so far I'm 3 years into the long life version, we'll see how long they go.

The other nice thing about buying CSB is they are usually fresher than the APC ones. SLA batteries can only sit off charger for about 6 months before they start to deteriorate.

The whole LiOn, LiPo, LiFe, etc thing is just scary. Totally different charging voltages, charging profiles, current ratings, etc.

The other nice thing about using CSB batteries is you can usually find larger capacity ones that will fit, nearly every UPS I've replaced batteries in I've been able to fit a larger capacity CSB in.

You would want to keep it on a float charger (NOT a trickle charger) as they will self discharge. You would want to keep it in a basement or garage when not in use and on the float charger. "Battery Tender" is around $20 and would work, same one I use on my car in the winter. Of course you will lose power while swapping the battery, I think it is a bit excessive, makes more sense to get a larger UPS. You can daisy chain 2 UPSs also, but typically not recommended as the transfer load of one might overload the other. Have seen it done just fine though. When I had two UPSes I just spread devices out between the two of them so the load was about the same.

Depending on the model of UPS it is usually pretty simple, most don't need any tools, some maybe a screwdriver.

FYI:
1. Chinese manufacturers could write whatever they want on their batteries but it usually far from reality. So do not hunt for a lowest price from unknown sellers. APC batteries will be the better choice.
2. Original APC RBC17 = CSB HR1234W with APC sticker on it (or few other brands). Buy CSB that's good batteries from Taiwan.
3. The quality of batteries depends on many factors: date of production, storage temperatures, etc. You can't check those factors so just choose trusted brand and buy from a reputable seller.
4. UPS = inverter + charger + batterie in one device. If you replace just one component - lead battery to a lithium "analog" there are many things that could go wrong. If you don't want to burn your house do not play that lottery.
Agree 100% with all of the above.

As soon as you pill off that expensive APC STICKER, that shinny OEM battery becomes generic with its own generic brand immediately.
CSB is under the sticker. Best SLA standby batteries you can get. Far from generic.

Duracell brand from Batteries Plus and a business account (free) is WAY cheaper. We paid around $17 each for 24 similar batteries to replace them in old Eaton units earlier this year. Sticker price was around $35 at the time. You would need to pick them up for that price though. Similar local battery shops may have similar pricing.
I've heard the Duracells are decent, however from what I recall they don't actually make their own SLA batteries, and the manufacturer can change anytime. I did compare some specs a few years back and they also had lower capacity in the same size as others. I think their 7.2AH was the same size as CSB's 9.

$17 is a good price though, may be worth it especially for the little cheap UPSes that are just there to allow a PC to shut down or run your router/modem.

I've had good luck with original APC and Cyberpower batteries. Cyberpower 1500VA lasted 6.5 years. APC 1500VA did maybe 7 or 8 years. I believe they are all CSB under the sticker.

Batteryspec (Tempest) lasted 4 or 5 years. Batteryshark (SigmasTek) lasted 4 years. Charity Battery from eBay is at 3.5 years and still working. Will try Might Max IF I need to replace batteries, but would consider CSB if it is on sale.

Properly balanceed LiFePO4 do not need BMS. Low voltage disconnect is good idea though as UPS shutoff voltage is on low side of LiFePO4 range but no issue charging.

new replacement batteries cost $21-22 on ebay for 12v 9Ah.
You can't just look at 9Ah, which only tells capacity but not current draw. Regular SLA battery is not suitable for UPS.

The higher VA the UPS, the higher discharge rate of the battery has to support.
The 1500VA Cyberpower UPS I have is using battery that support discharge of continuous 100A+ current.
Some reliable brand 12V 9AH high discharge for UPS costs $40+.

Other sellers just sell you some generic 12V 9AH without any specification sheet. You end up using battery that cannot supply enough power for your devices during outage and blame the UPS thinking your battery is new and good.

Comparing Powersonic to CSB is like comparing Yugo to Mercedes.....

Is this the type of battery that could go inside one of those kids plastic atvs?
