  The power radiated by a moving charge is given by Larmor's formula which can
be derived by integrating the Li\'enard-Wiechert potential over the whole past
history of the charge. However, extracting the same result from the
Lorent-Abraham-Dirac (LAD) equation of motion is problematic. This is well
known for uniform proper acceleration for which case the radiation force
vanishes and hence the very origin of the radiated energy is not clear, leading
to an energy balance paradox. The purpose of this letter is first to evince
that this problem occurs in the general case and not only for uniform
acceleration. Second we show that the widely accepted treatment based on the
bound field technique cannot fix the energy balance discrepancy. Indeed the
related Schott term is not a legitimate four-momentum for being indefinite and
not conserved.
