- This video shows how to replace the battery in a APC Smart UPS 750. The official APC batteries are somewhat expensive so I used an off brand that has seemed to work fine.

Finally, someone has the whole video on how to do this. Thank you so much.
Glad it helped
Thanks for the concise and clear video. Just updated my old UPS 750 with it's third set. Last replaced 10-16-2017. Took some elbow grease to get off the harness, and some gorilla tape to hold the Chinese replacements together. So far so good.
Excellent video. Sorted me right out, followed the instructions to the letter, including the purchase of the exact same batteries. Mine didn't come out as easily as yours did, but that was the only hitch. Thanks so much for this, so very helpful
the APC Smart-UPS series are almost all hot-swappable batteries, meaning you can leave them plugged in while changing batteries.
but since you didn't replace them with APC batteries, it makes sense to be on the safe side.
Bravo! Thanks. I managed but it was not easy as it seems ... the plugs were very tight 😳 but I managed. All set! Thanks, concise and precise.
You just saved me $100.
Thank you.
Nice concise video! Thanks!
Straight forward and to the point. Thanks!!
Thank you ! Excellent step by step instructions and commentary, addressed all of my concerns.
Glad it was helpful!
I am about to replace these batteries for the second time after some years. I opened it and went to Batteries Plus Bulbs and bought replacements. The good thing about that is they keep the old batteries and can dispose of them proper like. I imagine one could just go to an auto store or a Lowe's or something like that as well.
Thanks for the video.
Thank you for sharing!
The terminal size is ofcourse important but even more important is the physical size of the battery and ofcourse voltage (12V). The size used for this UPS is the most commonly used 151x65x94mm, Yuasa has a really good "made for UPS use" model NPW45-12, 8,5Ah. If you can find that one below list price it will serve you well. I just replaced 100 of these (actually NPW36-12) that hat had been in use for 6 years, which is one year too long, and all were still in fairly good condition.
Which batteries would you recommend for an APC SmartUPS SU1000 INET? The official ones are the APC RBC#6 and they cost a whopping 300€ xd.
@@prorace_type_r That depends on what you want to achieve, but I agree, that price is too steep. I would just get the dimensions of the batteries that you have now and look for batteries of the same size with the terminals in the correct position, that way you don't have to remake the cabling. Yuasa have served me well but there are other reputable manufacturers that you can source from as well.
@@MadsenWikholm I am just powering my PC and monitor with it. It has served me well, since it cost me with almost new batteries 30€.
Thank you! :)
hey first thanks for the vids.. I'm just wondering how long do they hold the charge for? compared to the real batteries
First time changing the battery. I loaded the new battery, but the metal plate won't click into place. Pulled battery out and it is the appropriate size and the one suggested for my model APC750. The front plate won't click into place because the metal one won't...... suggestions?
can I still open it when it’s at 100% battery? I got a replace battery warning and I wanna make sure my battery isn’t compromised so I can use it until I get new batteries
One question, you pu inside 9A 12 Volts battery, but the original was 7,2A. As the device is smart, did you have any issues to put the battery a 20 more powerful then the original? The second question if you had everything okay, did you notice a 20% more battery life comparing the original battery or the device charge your 9A battery to the 7,2 A limit and no runtime plus noticed?
Circuit battery input 24 volt?
I have a fair number of customers who have various versions of the APC Smart UPS 750.
Over the years the white push-pull plastic clips/rivets that keep the battery door closed have fatigued and fallen apart.
APC are unable to supply replacement ones and I can’t find any suitable alternatives anywhere.
Does anyone know of any replacements that will make a good alternative?
Currently I’m using cable ties to keep the battery door closed, which whilst very secure I’d like to do a proper job and replace the broken rivets.
Thank you 🙂
É muito boa eu estou a usar 😅
I had to replace the batteries in mine too. To modernize, have less environmental impact, and hopefully a longer service time, I bought this LiFePo4 variant (2x): GreenCell LiFePO4 Akku 10Ah 12.8V 151x65x95mm. Much cheaper than other ones, they fit perfectly, came with 64% charge and work as expected. I didn't do any measurements on capacity though.
A lot of LFP batteries of this size are only rated for around 10a continuous discharge. You're going to have trouble with your SMT750 if you're pulling more than 240w for longer than a minute.
@@kchiem you are correct. I should have updated my comment, because Indeed I did run into trouble because the packs cant handle the required current. So again: buy cheap = buy twice :(
@@MarkusRessel It's an issue that a lot of people don't realize even with the SLA versions of these batteries. You need to specifically look for "high rate" versions that can discharge at the current levels needed (a little over 30a continuous in the case of the SMT750).
@@kchiem You make a great point about finding batteries that can sustain the output current. That's critical for people who intend to max out the capability of the UPS (approximately 6.5A @ 115V).
I don't mean to disagree at all. But in my own case I use an SMT750 to run just my cable modem, router, and a backup hard drive, which are very low loads. My goal is to have them outlast a power outage. So I'm able to use a non-high-rate battery, like the Power Sonic PS-1290. The advantage is lower cost, higher capacity (9AH vs the original 7AH) for longer run time, and these are still able to sustain 27A for 7 minutes according to their datasheet. That's plenty of time if you've got a computer or small server set up with auto-shutdown, so higher loads are not out of the question.
So for anyone reading this comment, if you want original performance, then buy the APC branded replacement or 'high-rate' replacement batteries.
But if you are willing to figure out what your actual loads are, then you may be able to use the more common 'general purpose' replacement batteries.
Do the original batteries have a Ah rating printed on them?
Mine came with 7ah batteries.
Good day What's the name of the battery you bought
Has anyone had success using adapters to convert F1 terminals to F2 terminals? I've ordered two Yuasa batteries in order to do the trick mentioned in this video, but the terminal in the Yuasa is F1 unfortunately :((
