According to the PRO-34 manual, you can use alkaline or nickel-cadmium
batteries. The radio has a built in circuit for charging NiCads.

Newer scanners have two battery holders to prevent inadvertent charging of
alkalines. One holder does not connect to the charging circuit while the
other does. That's the only difference and there is no voltage
compensation.

Are you using NiCads? NiCads are only 1.2 vdc, where Alkalines are 1.5
vdc,
per cell. Multiply the difference by four cells, and brand new, fully
charged NiCads would produce 4.8 vdc, where Alkalines would produce 6
vdc.
So NiCads would look 1.2 vdc low, right from the start.

That is why a lot of the newer scanners have two different battery
trays,
depending on what type of cells you use. They compensate for the
difference.
