serial no.-290506287. it is a dry battery inverter, and in this model, the battery is inside the casing of inverter itself.
capacity-800VA/12V
total warranty: 2years on all parts
problem is that when it was in it's last 6 months of it's warrany period , i.e. 2 years, it stopped givin back up, even when we ran it on less load. we talked to the retailer but he said that there is some problem with the inverter, he told us that he'd call the engineer but he never called . this inverter was always a painful experience, even in it's earlier days,
it never gave a good back up. it was always giving buzzes of overload.
