Good price for an APC branded, 9Ah battery. They usually go as low as $35-40, but you may not be able to catch a sale when your old battery dies and you need a new one NOW.

That battery has a lower 7.2Ah capacity and smaller F1 terminals so technically not RBC17-compatible despite saying so (one reviewer used pliers to compensate for the loose connection). Mighty Max does have a 9Ah battery with F2 terminals for $23.55, curiously shipped and SOLD by Amazon [amazon.com] which may or may not be a good thing: for SLA battery with a limited storage/shelf life, some may prefer the seller ship fresh stock directly from their own warehouse (as with your 7.2Ah listing).

OP's listing is good when your friend needs a battery, since you don't want to be blamed for getting an off-brand if it doesn't work. For myself, I usually buy at least 2, and I can get (2) 9Ah for around $40 shipped from battery specialists like BatterySharks.com. Those popular CyberPower 1350VA/1500VA UPS towers each take two 7Ah/8Ah/9Ah F2 batteries (model RB1270/RB1280/RB1290) if you reuse the old wiring harness.

Also, I ensure that the UPSes that I buy can take the larger 7-9Ah battery size (as smaller sized batteries aren't much cheaper). Those used to be commonly $40 and under back in the Staples coupon days but for the last few years the cheaper models come with physically smaller 5.5-6Ah batteries.

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.

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.

Just got some Amazon Basic UPS and was going to toss a couple APC UPS since I didn't want to deal with their special size batteries. Guess I'll get these and keep them as backups now.

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?

batteryhookup dot com. They had 26650 A123 cells, probably the best LiFePO cells ever made. I harvested some from DeWalt packs over 13 years ago that is still holding a charge today. They also had some K2 SLA UPS drop-in replacements as well, it looks just like this APC SLA with BMS built-in but it's LiFePO. The LiFePO's charging profile is also not the same as SLA, but it can tolerate it due to the robust chemistry. You can abuse the heck out of them and they wouldn't care.
While almost certainly not the one you're talking about, the only K2 battery I see on that site has a maximum discharge current of 24 Amps, about half of what a UPS using this capacity battery could draw.

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.

They are a battery recycler. Different stocks come and go. So you have to check back.

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.
He makes more sense than you. Lithium batteries such as those used in laptops have a fully charged voltage of 4.2v and then level off at 3.6-3.7v under discharge and are more dangerous being charged. LiFePO4 are fully charged at 3.5-3.6 and level off at 3.2v which gives a nice 12.8v vs 14.4-14.6v for the conventional lithium and you have to do something really stupid to have LiFePO4 set on fire. I have about 42,000Wh of LiFePO4 in my home on standby but my UPS runs off 100Ah AGM SLA batteries as they like to always be fully charged vs lithium which degrade at full charge. Power outages are rare for me anyway so i don't get much use.

As soon as you pill off that expensive APC STICKER, that shinny OEM battery becomes generic with its own generic brand immediately.

I've been getting all my ups batteries from battery sharks. Good prices and I get the 9ah batteries. Usually comes to about $42 with shipping for two for a Cyberpower 1500. Amazon seems like a "I need it yesterday" type situation.

new replacement batteries cost $21-22 on ebay for 12v 9Ah.
Most of those are garbage, tried and learned my lesson. They do not charge to the rated capacity and lifespan is short.

I strictly use CSB batteries now (most likely what this one is but with a markup for the APC sticker over it).

Avoid these off brand batteries, 90% of them are garbage (and that's a conservative estimate).

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.

Just an FYI.
I understand that this is not for everybody...but if you are a little handy, you can replace this Lead Acid battery with a DIY LI-Ion battery made with 18650's.
You get the same benefits here as you do elsewhere with this change.
Lithium batteries charge completely differently than SLA so you'd need to design a circuit to modify the output of the UPS to something that will be compatible.

And while decent 18650s have basic protection chips in them, the cheap ones don't, and even the good ones that have them, it is just there to hopefully prevent explosion/fire, it isn't going to stop the batteries from excessively heating or dying early due to improper charging. Not something I'd want to risk. There are UPSs now with Lithium batteries and charging circuits to support them properly.

Just urging some caution here.

For as much as they charge for these UPSes in the the first place, I'm surprised they haven't switched to lithium yet. They must be making a killing on the UPSes and the markup for stores must be huge too, due to the good sales on them at BF/CM.
They do have some industrial/corporate ones with Lithium batteries, but this battery is for their small/cheap home ones that would double in price if they were to use lithium.
