Liberty 441 Battery Backup Sump Pump vs Pro Series PHCC-2400 Battery Backup Sump Pump

The Pro Series PHCC-2400 moves far more water on battery power, rated 2,400 GPH at 10 ft of head, and its 13 amp charger plus electronic alarm make it the stronger backup for a finished basement in a wet climate. The Liberty 441 is a compact, lighter system that pairs a 1/3 or 1/2 hp primary pump with a 12 volt backup and a 5-stage charger, so it suits a pit where space is tight and you want one integrated unit. Both are 12 volt DC backups with automatic switches; the Pro Series is the higher-capacity, more feature-rich choice, while the Liberty is simpler and easier to handle.

• Choose the Liberty 441 if you want a compact all-in-one primary-plus-backup unit with a 5-stage charger and a mercury-free switch, and your pit is short on room.
• Choose the Pro Series PHCC-2400 if you need maximum battery flow, long runtime with one or two B12-100 batteries, and an alarm that warns you before the backup is needed.
