How many batteries can I connect together and fill at one time?
- A maximum of 6 batteries can be plumbed together with the Pro-Fill RV Edition system, although many users prefer (for ease of filling) to limit the number of batteries plumbed together at 4.

When is the best time to fill my batteries?
- Water after charge. Water must always be added after fully charging the battery. If your battery charger has an equalize function it is best to add water after equalizing the battery. Prior to charging, there must be sufficient water to cover the plates. If the battery has been discharged (partially or fully), the water level should still be above the plates.
Electrolyte levels drop during discharge and rise during charge. In addition, charging generates heat, fluid expansion and explosive gases. Watering a battery before charge (or with a low charge level) can lead to boil over resulting in potential damage of the watering system, battery and vehicle. |
How often should I fill my batteries?
- Watering intervals are dependent on the local climate, charging methods, application, and age of batteries. For most RV applications filling once per month is adequate. High use RV applications may require filling every two weeks.

Can I leave the water supply connected to my batteries at all times?
- No, Leaving a water supply connect to the your SPW system will cause the batteries to be over filled. Always disconnect after filling is completed.
