Delta PowerMaxx

The Delta PowerMaxx Battery backup is designed to power V3 basement pumps when there is a loss of mains power. If the pump loses power, the battery backup kicks in and keeps the pump running for up to four days. This allows the sump pumps to continue to safely discharge water from a basement even during a power cut. This battery backup is specifically designed to run one or two V3 groundwater pumps without mains power. When power fails, the pump(s) automatically take power from the PowerMaxx. This battery backup will have been fully charged during mains operation. It will automatically recharge when mains power returnswww
