APC Battery Backup makes loud high pitched noise all of a sudden
March 2, 2013 at

This has happened multiple times. I'm watching TV and all of a sudden the APC unit will make this constant, loud, high-pitched noise. Nothing turns off as if the unit failed or something but the noise is unbearable. I turn off my TV and HTPC and then turn off the APC unit for about a minute, turn it back on, and the noise is gone. It isn't really that frequent but has happened at least three times. What is the issue?

You need two batteries...

The APC Back-UPS POWERSTACK 450 UPS Battery requires 2 batteries to replace it. The price above includes ONLY 1 of them.The APC Back-UPS POWERSTACK 450 UPS Battery is replaced by this high quality replacement. Double check the actual size of the batteries being replaced. UPS replacement battery packs contain replacement batteries only. You must reuse your existing cabling and hardware. APC model numbers are very similar so check the model number listed here with the barcode label on the back or botto.
Edit: This [ecomelectronics.com]should do nicely. I bought this brand from this company for my 350VA UPS from APC and it has been working great.
edit: how long are the warranties? I have to check my records but I think I've had this thing less than two years. That seems kind of quick for the battery to die. Is there a right way and a wrong way to initially charge the battery?

i pay $17-18 for 7.5Ah APC batteries from ebay - not cheap, but that includes shipping.
