    • 4 min read

    Like other home appliances or devices, the household sump pump generally uses power from the grid. However, many people are wondering if they can add a battery backup for their existing sump pump to provide an additional layer of protection during power outages. The answer is yes, and, in fact, it is easy to install one. This post will tell you all things you need to know about sump pump battery backup and help you choose the top battery backup.

    What Is Sump Pump Battery Backup and How Does It Work?

    A sump pump battery backup is a device that provides backup power sources for your sump pump. It usually has a rechargeable battery and a device that recharges electricity to the battery to ensure it remains ready for use. Some battery backup needs to be recharged by electricity from the grid, while some can gather renewable solar energy with solar panels. The backup battery system can be plugged into the existing sump pump directly. When there is a power outage and consequently a malfunction of the sump pump, the backup battery is ready to activate and input electricity to the sump pump, keeping it functioning.

    Why Should You Prepare Sump Pump Battery Backup

    It is wise to prepare a sump pump battery backup in your house, especially for those who live in a heavy-rain or flood-prone region. The sump pump collects water from the house foundation and redirects it out of your house, ensuring proper drainage and keeping the basement from being flooded during rain and snow thaw. However, the sump pump is not able to run itself when there is a power failure, causing water accumulation and flooding in the basement. In this case, the basement and house foundation could face the risk of structural damage and you may need to spend more money on repairing it.

    A sump pump battery backup ensures the well-functioning of a sump pump during a power outage. With a backup battery to your sump pump, you don’t have to worry about your basement every time there is a power outage, and it saves you time and money that spends cleaning and repairing the messy basement.

    How to Choose a Battery Backup for a Sump Pump?

    Although it’s a backup device, the battery still requires essential qualities to support your sump pump system. It’s critical to choose a backup system that is dependable and effective during emergencies. Here are some key factors to consider:

    1. Battery Capacity: Think about the size of your sump pump and itspower requirements to choose a backup battery system that covers the power consumption of the pump. A battery with a large capacity is recommended because it can keep the pump running constantly for several hours, and 3-5 days when used occasionally.
    2. Recharge rateChoose a backup battery that can be recharged quickly for a high recharge rate ensuring that the battery is always ready for use.
    3. LongService Life: The backup battery system should be a long-lasting device, reducing your cost of frequentlyrepairing or replacing the battery.
    4. 4. User-friendliness: The battery backup should have a reasonable and clear function design, making it easy to install and recharge for non-professional people.
