COMMENTS:
          Discharging cells smaller than sub-C size-
            Do NOT Discharge Cells which are Smaller than Sub-C Size. This is
            is to include A and AA size (and smaller) cells which are normally
            installed inside radio transmitters and so on. The discharge
            current rate of the IntelliPeak is too high for such smaller cells
            and the wiring which is used to assemble such packs. Failing to
            avoid this will likely cause permanent damage to the cells and/or
            wiring in the battery packs, and possibly the equipment in which
            the battery is installed.

          Fixed discharge cutoff voltage-
            The IntelliPeak Charger has a fixed discharge cutoff voltage
            setting of 2.60V. This cutoff voltage is not adjustable. If a
            specific discharge cutoff value other than 2.60V is desired,
            monitor the pack voltage during discharge with a separate voltmeter
            (or the built-in LCD on the IntelliPeak Digital Pulse Charger) and
            manually terminate discharge at such point as desired.

          NiMH Battery Care and Handling: It is important not to allow NiMH
            batteries to overheat while being charged. Heat can adversely
            affect the performance of NiMH batteries. The Zero Delta V
            technology is designed to allow for high rate, 6.5A fast charge
            without adverse heating of the NiMH battery. If overheating is
            observed, disconnect the battery from the charger immediately
            and reduce the charge rate for future charging needs.
           -Also, Do Not Deep-Cycle NiMH batteries.  Permanent damage could
            result. Store NiMH packs with some voltage remaining in the cells.
           -Use a NiMH battery pack no more than three cycles per day, with a
            two to three hour break in-between for cooling. More frequent use
            is likely to overheat the pack.
          WARNING: Do Not leave charger unattended during fast charge. If the
            battery or charger becomes hot at any time, disconnect the battery
            from the charger immediately.
           -Do Not charge 4 or 5 cell batteries at a rate greater than 4.5 amps
            as this could cause excessive heating in the charger itself.
