Low Battery Indication - Vertex Standard VX-530 Series Operating Manual

Low Battery Indication

As the battery discharges during use, the voltage gradually becomes
lower. When the battery voltage falls below the operating voltage range
of the radio, it is time to substitute a freshly charged battery and re-
charge the depleted pack. The LED indicator on the top of the radio
will blink red when the battery voltage is low.
Avoid recharging Ni-Cd batteries often with little use between charges,
as this can degrade the charge capacity. We recommend that you carry
an extra, fully-charged pack with you so the operational battery may be
used until depletion (this "deep cycling" technique promotes better long-
term battery capacity).
