BI 800 I against invoice no. 0704091 dated 30.04. 2007.CASE HISTORY- at the time of purchase dealer convince me to by this model showing addl. features compare to other model. as the multi national i have to decided by APC so purchased the same.i have committed warranty for two years on both battery and main unit.problem started fron april 2008 when performance was not good. i have lodge a complaint no. C[protected] and on gt. 10/04/08 m/s smart microcare ( service centre nagpur ) chacked and came to know that inverter charging voltage is faulty and poor and the main unit replaced on 16/04/08 vide machine no.

I too faced the same problem with my APC Inverter BI800 Model. I think inverter does not cut off battery charging. Please be update me also when ever you receive any response.
