- Check Generator function (where installed) and synchronisation with inverter for battery charging purposes
- Check Tanesco power input and power conditioning to confirm functionality
- Charge batteries to full – inverter in float – and check that battery condition monitor synchronizing appropriately
- Measure individual battery voltages and cell specific gravities when battery bank fully charged and record
- If required, battery equalization will be performed and battery specific gravity levels recorded again
- Batteries topped up with distilled water if required
The following materials will be supplied (when required):
- Necessary (measurement) tools to perform tasks outlined above
- Distilled water (specifically produced for batteries)
The following training will be provided on-site (when required):

| Status of different components | Battery Specific gravities (before equalisation) |
| Electrolyte level | Battery Specific gravities (after equalization) |
| Battery voltage | |
| Maintenance and tasks performed | |
| Recommendation on | Pictures of: |
| System Management | System anomalies that can be illustrated photographically |
| System Maintenance | |
| Follow up requirements to findings from maintenance intervention |
