+The 'mix', 'sph' and 'spa' types set the battery program in a single command, so all parameters - except `enableAcCharging` - <u>**must**</u> be ***non-*** 'null'.
 By contrast 'tlx' types set the battery program in up to four partial commands, and you may pass 'null' parameters in order to omit a partial command.
 The permission for passing 'null' parameters, and the effect of such 'null' parameters, is shown in detail in the table below:
