To those who rebuild packs, be careful! I had the plastic insulator for the positive cable fall off before and the terminal welded to the chassis. Fun times!
12.12V at room temp is around 30% state of charge. That means they’ve been sitting on someone’s shelf for around a year. I like to see my new batteries between 12.6-12.9V.
Thanks for the video. Have you ever done a hotswap of the battery pack on one of these APC units without powering down the UPS? Batteries were on the list to change out, but just got the failed self-test alert this afternoon.
The middle ones I don't know if you could do with both ends in place. I kinda think not, but if it's possible then sure. Keeping the cabling straight is the main thing so whatever accomplishes that for you do it. No matter what, take a lot of pictures before you uncable it.
You've had good luck with this brand of battery? I've got four dead 7 amp batteries sitting right next to me for the last (far too many years). I had thought about getting these 'Mighty Max' brand batteries because there was some bundle pack on Walmart for cheap (70 bucks for a 4 pack, 130 for an 8 pack), but was concerned about them after seeing some bad reviews. It would be nice to have the two 600va and one 1000va back in action. That 1000va would be a great upgrade for the network closet. It has a 600va that's been used as a surge only device for more than a year. lol
Yeah I've had good luck with this brand. I've rebatt'd (made that word up) a 20 pack of these in a tripplite SU 10k and the ones I pulled outta this APC UPS about 3.5 years ago. I sold that 10kva UPS but it's runtime was still in spec and this UPS I just did had a recent power drawdown and was in spec. I tested the batts I took out and only one of the four cells was slightly low at 11.9V, the other 3 where at or above 13. I have a second APC 1500 that I went with another brand to save a few bucks. Didn't last 2 years. I'll tag you on T with a photo of that mess. Had to buy a new tray and cable set...
I've not found anyone parting with a 10kW class UPS for free ever, but I have ran into them for drastically cheaper prices vs new on 2 occasions, for a total of 3 10kW units. Both times I felt like I got a good deal and the company that was out of business as well. One of those UPS even took the brunt of a bad lightning strike on the pole on our property. It saved 18K worth of drives... This is why I wouldn't say "never" myself, at least for a large unit locally.
@@DigitalSpaceport a 10KW, yeah it's rare to find free, but I do have 2 5U APC 208v monsters I got for free, so they do happen... and if you have enough rack space you can certainly stack em
@@MainelyElectrons awesome find! Yeah IME between the costs of shipping and renewing the battery most places just want it off their hands, but DS does make a point that at some point the bigger systems still have some value.
I didn't delete any comment. just checked the comment filter and there is nothing being held for review. Please repost whatever you had posted again, UA-cam is weird sometimes.
@DigitalSpaceport okay sorry was just letting you know I sold all my ups,s off after I installed 24kwh solar battery system from sigenergy, the sigenery gateway cuts in if blackout occurs with zero downtime instantaneous, didn't even know until app on my phone told me of blackout basically I have one big ups. Unbelievable how good it works, of course you could go smaller 5kw 8kw batteries mix n match . My whole system with panels 24 x 440w 24kwh battery $14800 usd installed.
Batteries Plus worker here thanks!

You can hotswap them. Just do the plug part firmly and controlled.
@DigitalSpaceport thank you, will give it a go.
can i replace the batterry as i take them out or out all the way then replace ?

Excelent Video.
I missed this - were there any sparks flying this time ? 😮 👍🏻
Negatory
@@DigitalSpaceport 👍🏻
never buy a used UPS, because they are basically free, since most of the upkeep cost is in the rebattery cost, places will basically give them away

@@bitcoinsig I also got a sweet rack mount UPS for free that a business tossed. 4U 3000watts!
