Hi,

I suggest that you look for a small white sticker on either the bottom or rear of the UPS. Please note that the location of the label, as well as the letter and number sequences will vary by model and UPS type, that way you can make sure that you'll get the correct part number for the batteries you need. By the way, how old is the unit? You may also want to get in touch with your local [APC help desk|http://www.apc.com/support/contact/index.cfm?ISOCountryCode=WW] for proper assistance (to determine if the unit is still under warranty, troubleshooting to determine if its the unit or the batts that need replacement.

I'm not sure local APC can help with technical advice that can plug the 150 amp batteries for UPS 3000va, I think they often explain and advise us to use the same genuine battery the old kind - but that means we will have to spend large sums of money for a small amp batteries with the use of power ups to much shorter

You are correct, the recommended solution is to use the same rating battery that was provided with the UPS. The easiest way to do this is to purchase the appropriate RBC pack from APC or one of their resellers. You can also try to locate identical batteries elsewhere, but of course you're relying on your skills in identifying an appropriate replacement, dealing with assembling it (many aftermarket ones don't come with cables, etc.) and any reliability issues that may be caused by that. What might be reasonable for a hobby / home user would likely be unacceptable for a business.

In your case, you seem to be considering a battery that has a far larger capacity than the UPS was designed for. That is a bad idea for a number of reasons. First, if there is an internal fault in the UPS your batteries can provide far more current for a longer time which has the potential for a disaster. Even if that never happens, the UPS would have a very hard time recharging such large batteries after a power failure.

As background, I discussed this very issue with APC engineers around 15 years ago - modifying a number of Matrix 5000 units to run off a telco 48V 600A battery plant by disabling the UPS charge circuitry and installing appropriate fuses. The amount of work needed to make it safe and reliable made it impractical - it was easier to engineer replacement power supplies for the loads in question to run them from the telco 48V directly.
