Apc es 500 making a buzzing sound when plugged in


Hi,

Sounds like it could be a bad battery connection or the unit is damaged at the internal components level - probably the charging inverter. You can replace your UPS using APC's Trade-UPS Program: http://buy.apc.com/commerce/storefronts/tradeups/tradein.aspx?storefrontcode=apcetu&countrycode=us&languagecode=en&tradeups_id= Make sure to pay attention to the country/region before you start filling out your information -- the link send you to the USA country.

We also sell them -- the direct replacement unit is a BK500BLK.... $116.70 your price not including shipping. We ship anywhere in the USA.

It is not entirely risk free to change the batteries.
If you saw a spark at the connection of the new batteries, UPS may have been damaged.
Next time, preload with a 100 Ohm resistor in series with the battery to limit the inrush current!

Apc xs800 new batteries


I Bought two RBC32's and had to hook them up to the connector and did it wrong on the first try. Make sure you connect the yellow to the Red terminal on one battery and the Black on the other, then connet the remaining red to red on one and black to black to the other. Once I did that and plugged it back in everything worked fine.

APC SMARTUPS 1500VA Battery Problem When Replaced


You are correct. The APC Smart line has a partial charge when it's new. Similar to cordless phones, the work right away, but you're still supposed to charge them before use for best results.

Just leave it plugged in with no load for a couple hours and it will be fine.
