If you are setting the number of repetitions to 0, then this is
exactly equivalent
to a GETNEXT request.

Why not simply use

    snmpgetnext  -c  public 192.168.1.11 batteryVoltage batteryCurrent

to retrieve the first pair of values?
(Which would work with both SNMPv1 or SNMPv2c).


Or if you know the index values that you are interested in,

    snmpget  -c  public 192.168.1.11 batteryVoltage.0 batteryCurrent.0



The whole point of  BULKGET is to retrieve *multiple* rows with a
single command (using a non-zero value for -Cr)
