Hi-PowerMaxx2 XL Battery Backup

Hi-PowerMaxx2 XL Battery Backup

Hi-PowerMaxx2-XL Battery Backup Power Solution for Uninterruptible Power Supply.

If a submersible pump loses mains power, the Delta Hi-PowerMaxx2 XL battery backup kicks in and keeps pump running for up to 100 days (depending on number of cycles/days). This allows the sump pumps to continue safely discharging water from a basement even during a power cut. This battery backup is specifically designed to run one or two D10 pumps without mains power. When power fails, the pump(s) automatically take power from the Hi-PowerMaxx2 XL. This battery backup will have been fully charged during mains operation and will automatically recharge when mains power returns.
