=item B<--unknown-status>

Set warning threshold for status (Default: '%{status} =~ /unknown|notPresent/i').
Can used special variables like: %{status}

=item B<--warning-status>

Set warning threshold for status (Default: '%{status} =~ /low/i').
Can used special variables like: %{status}

=item B<--critical-status>

Set critical threshold for status (Default: '').
Can used special variables like: %{status}

=item B<--warning-*> B<--critical-*>

Thresholds.
Can be: 'charge-remaining' (%), 'voltage' (V), 'temperature' (C).
