Top-10 Sump Pump Battery Backups
Loved in the USA

The WAYNE 1/2 HP Basement Sump Pump System is designed for indoor use, making it a good choice for homeowners looking to keep their basements dry during heavy rains or snow melts. One of its standout features is its impressive pumping capability, able to handle up to 5,100 gallons per hour, which is beneficial for managing large amounts of water quickly. Additionally, the system can remove about 10,000 gallons on a single battery backup charge, ensuring your basement stays dry even during power outages, although you'll need to purchase the battery separately.

Installation is made easy with a preassembled design that allows for drop-in setup in about 15 minutes. This is a big plus for those who aren't very handy, as it requires no drilling or complex setup. The unit has been tested for durability, lasting through a million cycles, which speaks to its reliability over time. The three-year warranty adds to the peace of mind for buyers.

However, there are some considerations to keep in mind. The fact that the battery is sold separately can be inconvenient and adds to the overall cost. Plus, it's important to note that this model is designed strictly for indoor use, which might not suit those looking for a more versatile option for outdoor spaces. With a maximum lifting height of 20 feet, it should meet the needs of most basements, but some may find it lacking in certain extreme conditions.

The Basement Watchdog Big Combo CONNECT Model CITS-50 is a robust sump pump system that combines a primary pump with a battery backup, making it a strong choice for homeowners concerned about flooding. The ½ HP primary pump is energy-efficient and has an impressive capacity, moving up to 3,540 gallons per hour at a 10-foot lift, which is ideal for handling significant water influx during storms.

One of the standout features is its WiFi capability, allowing users to monitor the pump and its battery status 24/7. This means you can receive real-time alerts on your phone or through email, which is great for peace of mind, especially if you’re not always at home. The included alarm system further enhances this, providing audio and visual warnings for maintenance needs.

When it comes to battery support, this system is versatile, accommodating both maintenance-free AGM and wet-cell batteries. Users can even connect two batteries for extended run time, which is a big plus if you live in an area prone to power outages. The requirement for a separate purchase of the Basement Watchdog CONNECT Module for advanced alerts may surprise some users looking for a fully inclusive system. Additionally, while the installation is generally straightforward, it might still present challenges for those not comfortable with DIY projects.

The Superior Pump 92911 kit combines a reliable primary cast iron sump pump with a 12V DC backup pump, offering good protection against basement flooding even during power outages. The primary pump moves up to 4,200 gallons per hour and can lift water up to 25 feet, which suits most residential sump basins. Its cast iron build adds durability compared to plastic models.

The backup system runs on a 12-volt deep cycle battery (not included), and the kit includes a charger, alarm, and control panel with indicator lights—features that help you monitor the pump’s status easily. Installation is straightforward since it comes pre-assembled with mounting hardware and a battery box, making it beginner-friendly. The alarm system at 87 decibels is loud enough to alert homeowners but might be a bit jarring if you’re nearby. The product has a 3-year warranty, providing some peace of mind. However, the backup battery must be purchased separately, which adds to the overall cost.

This kit is well-suited for homeowners wanting a dependable primary pump with a battery backup system that is easy to install and monitor, but you’ll want to ensure you have an appropriate battery to maximize backup run time.
