Hi there my friends !

I manage to get an su3000RM3 for cheap.

After years of great service, the unit started to require new batteries, wich i acquired and installed.

The question is, even after replacing (on-the-fly) the batteries an let then recharge (for 8 hours straight) i ran the callibration test and it immediately beeped, showing the "Battery Discharged" warning.

am i doing something wrong ? I've carefully replace the batteries and everything.

Also, im using a (clone maybe?) prolific USB->Serial converter to talk to the unit, and after sometime (1 hour or more) of idleness, i lost the communication and i have to restart the APC service to reconnect to the unit !

Thanks for the help

Hi Douglaster, what type of batteries did you purchase for this unit (were the APC batteries and if so what was the part number). You could verify again that the batts are in fact securely connected and once connected have been charged. In regards to the usb to serial, how exact are you communicated with the unit (via Hyperterminal, or by some APC software)?

In addition to what R2 has said, make sure that you have the most recent updated USB driver for your Prolific (if this is what you are using).

Hi Douglaster, what type of batteries did you purchase for this unit (were the APC batteries and if so what was the part number).

-- It came with C3 12v 7.2a batteries, and i purchase the new ones from an local batteries manufacturer (http://www.globalpower.com.br/)

You could verify again that the batts are in fact securely connected and once connected have been charged.

i've tri-checked then already =[

APC Powerchute, the os is win 7 64bit.

This afternoon, i will try disconnect all devices, remove the batteries and let it stay without any power for 3 hours, lets see if this will work it out.

Also, the prolific drivers aren't the problem, since if i restart the apc service it come back online instantly

Thanks for the help guys !
