It won't fit, but it will work (external fitment). Just keep in mind that the charging circuit in that UPS was not designed for a 40AH battery.

You might have to open up your UPS to see if it has 1 (12V) or 2 (24V) batteries though.

Edit: As per the specs I see 1 x 12V.

Most UPS's under 1000VA are 12v and use 1 battery.

Both my APC UPS's at home have huge external batteries that I fitted years ago.
They run like a dream
Just bare in mind the charging circuit will run hot as it runs for a long time replenishing juice back into your battery.
I have had no issues with APC myself.

LOL No fire yet, luckily my APC inverters stay cool when recharging the battery after load shedding.
I modded a no brand name one like this years ago and it gets bloody hot. Hasnt blown up yet (that I am aware of, in my exes lounge)

You're freaking me out with the red cable running from the negative pole into your UPS.......:X3:
 
Hi Chuckmyster! This is awesome!

Could I ask some Qs?

1. How many watts can you pull and for how long? I'm looking to power 2 POS machines and a server pc for 2-3 hours aka loadshedding.

2. Which APC model do you have?

3. Did you remove the internal battery or are the cables connected to it?


Thanks a million!!
 
Do you want to extend backup time? Takealot:
Note:
A UPS is not designed to provide continuous power, merely a window period that allows a computer or other user to finalise the work at hand and shut down.

RCT may use 24V (2x 12V 7AH batteries in series) so just check that out too.
