 Sounds like either the battery is almost dead, or the inverter is defective and drawing too much current.

Charge up the battery with the inverter disconnected and see if it holds it's charge for a lots of hours. If it does, the inverter is probably bad.

But my bet is on the battery. Depending on the type, some batteries don't last long. If this is an auto battery, it can only take a few discharges before it is dead.

 Most types of batteries used in inverters have some internal leakage that will slowly discharge the battery. For lead-acid batteries, it typically takes a couple of months for this to be significant. In addition to this, the inverter may have some monitoring circuitry that continues to operate even when the battery is fully charged, and this will cause it to discharge slowly. This is particularly noticeable on older designs that don't make use of very low current electronic circuitry.
