Hi all,

Just trying to find a supplier for 12V 7.2Ah UPS batteries.
Need the typical 3 invoices :(
Only found Sinetech so far.
Anyone know of any other companies I can contact?

I used Cape UPS that's if you are in the Cape Town area, but I am sure there are others. What area are you in?
 
Any alarm place will also sell the batteries, and pretty much any shop that sells UPS's will either sell the batteries, or tell you where to get it, or source if for you.

Hi,


If you're looking to replace your RBC2 12v 7.2ah battery, make sure you pick up a battery that weighs around 2.2-2.4KG. A little less or a little more won't hurt, if it's significantly less, run!


There's a whole bunch of newly imported stuff now that weighs much less, has much less lead now and has life time of about 1 year. This is a way that the manufacturers have found to get around the expensive lead prices, less lead and don't tell the consumer!


Just a tip!



Tony,
 
Weird thing is my UPS at home has a battery life of 25seconds, it is only 14 months old. I did leave it on charge the other day, but same result. :(

One more question, can the Ah differ, my UPS have a 7Ah, can i put in anything different? Like a 7.2Ah

More Amp-hours (Ah) will give you a longer runtime after power failure.

Two things to be careful of though: Bigger Ah can sometimes mean higher charging currents and this could burn out your UPSs' charging circuitry. Some UPSs are designed to only be in UPS mode for a short time and may overheat if you put in batteries that are too large.

25 secs is about right. Long enough to save and shut down. You can connect up a bigger battery (run the wires to the outside of the unit and use a car battery) but then you need to jury rig some decent cooling for the unit, as it is not designed to run much longer than a minute or two. My 1000 va unit runs on two truck batteries for about 5 hours, but the fan cooling the ups innards drives you mad after about 10 minutes.
