I have an APC SRT5KRMXLT UPS at my office that is indicating I need to replace all the batteries. I'm looking for some advice on how to go about this without breaking the bank. Here are my questions:
1. The battery part number I need is apcrbc140. Should I buy these directly from Amazon, or is it better to just purchase individual batteries and put them into the metal casings that come with the apcrbc140?
2. I'm planning to do a hot swap for the batteries. Do I really need to power down the UPS or switch it to bypass mode, or can I just replace the batteries on the fly?
3. Has anyone purchased these batteries from Amazon? I found what seems to be the official APC store link there. Do they still back the 2-year warranty if I buy through Amazon or other sellers?
Thanks for any help! I'm new to the IT side of things and want to manage this replacement easily and cost-effectively.

The answers to your questions mostly hinge on your company's policies regarding compliance and authorized retailers. For example, if you're in a sensitive field like healthcare or finance, it might not be suitable to buy batteries from Amazon if they aren't an authorized seller. Just check your internal guidelines before proceeding!
We usually purchase our UPS batteries from a local battery store. They offer brand new batteries at a better price and quicker service compared to online sources. If you do decide to buy from Amazon, make sure it's an authorized reseller to keep your warranty intact. Just remember, going for authorized replacements via Amazon often comes with a hefty premium—I've seen prices nearly double. In my experience, third-party batteries have worked just fine and can save a lot of money.

I'm a contractor for a government agency, and I've been told the team often orders tech via Amazon. It's a bit sketchy since I didn't realize that was okay, but that's their approach at the moment.
