Sump Pump Battery Backup: What You Need To Know
When the power goes out during a heavy rainstorm or flash flood, your sump pump is your first line of defense against a flooded basement. But without power, that pump is useless—unless you have a sump pump battery backup.
Batteries Store offer high-performance sump pump batteries designed to protect your home from water damage when it matters most.
What Is a Sump Pump Battery Backup?
A sump pump battery backup is a secondary power system that automatically kicks in when your primary sump pump loses power—typically during outages caused by severe weather. It ensures your sump pump keeps running and draining excess water from your basement, crawl space, or foundation.
These battery systems are essential for Canadian homes, especially in areas like Calgary, where spring melts, heavy rains, and flood warnings are not uncommon.
Why Do You Need a Battery Backup for Your Sump Pump?
Here’s why a sump pump battery backup isn't just a luxury—it’s a necessity:
1. Protection During Power Outages
Most sump pumps are electric, meaning they stop working during outages. A battery backup ensures uninterrupted operation when you need it most.
2. Flood Prevention
Even a few inches of water can lead to costly structural damage, mold growth, and ruined belongings. A backup keeps your basement dry and safe.
3. Peace of Mind
You can’t always be home during a storm. A battery backup system gives you the confidence that your home is protected, 24/7.
How Does a Sump Pump Battery Work?
The system includes:
- A battery unit (typically deep cycle or AGM)
- A battery-powered backup sump pump
- A charger/controller
When the power goes out:
1. The main pump fails.
2. The controller automatically switches to battery mode.
3. The backup pump takes over and keeps discharging water.
Pro Tip: Many systems come with alarms to notify you when the battery backup kicks in.
Types of Sump Pump Batteries
When shopping for a backup battery, you’ll typically choose from:
1. Deep Cycle Marine Batteries
- Affordable and widely available
- Designed for long, consistent energy output
- Require regular maintenance
2. AGM (Absorbent Glass Mat) Batteries
- Sealed and maintenance-free
- Spill-proof and vibration-resistant
- Longer lifespan and faster charging
Batteries Store recommend AGM batteries for homeowners looking for a durable, maintenance-free solution.
How Long Does a Sump Pump Battery Last?
Battery lifespan depends on usage, but typically:
- One full charge powers a backup pump for 6 to 24 hours (depending on the system and volume of water)
- Battery life expectancy is 3 to 5 years with proper care
Always test your battery system at least twice a year, especially before the rainy season.
Signs It’s Time to Replace Your Sump Pump Battery
Watch for these warning signs:
- Frequent beeping or alarm from the controller
- The battery doesn't hold a charge
- Reduced pump runtime
- Corrosion or leakage
Don’t wait until the next storm—replace your battery before it fails.
Battery Maintenance Tips
Maximize performance and lifespan with these simple practices:
- Check water levels (for wet-cell batteries) monthly
- Keep terminals clean and corrosion-free
- Use a smart charger to prevent overcharging
- Test the system regularly by unplugging your main pump
