5 Best Battery Backups for Existing Sump Pumps [2023]
As technology advances, more and more homeowners are making the switch from traditional sump pumps to battery backups. A battery backup for a sump pump is a great investment for any home, as it can help keep your basement dry during a power outage or other emergency. If you’re considering purchasing a battery backup for your existing sump pump, check out our list of the five best options on the market in 2023.
Sump pumps can become your worst enemy after a power outage, but they may also be your greatest protectors. Fortunately, we now have a variety of options to ensure that our sump pumps continue to function in the event of a power outage.
The simplest way to do so is with batteries. You may either install a battery backup sump pump that works straight off the bat, or you can utilize an inverter to convert the juice from your batteries into the form needed by your main pump. This may offer you more protection without requiring the installation of another pump in the pit.
In this post, I’ll reveal to you which battery backup is ideal for existing sump pumps of both kinds. I’ll also address some questions you may have about them. So let’s get started.

Which battery backup is right for your house?
Before we get started, if you’re not familiar with the difference between DC power and AC power, DC is what you receive from a battery, while AC comes from your home’s electricity outlet. There are two distinct methods for adding a backup battery to an existing primary pump:
1. Battery backup sump pump
You’ll need a separate power source for each pump, and you should use an extension cord. Each pump must be powered by its own battery or generator. If you already have a sump pump installed, this is the setup to choose. You’ll need to place the second pump within the basin since there won’t be enough space below it for both of them.
The float switch for the backup pump is generally set a few inches higher than the on point of the primary so it activates only when the water level rises excessively. Because you’ll be using it when the major pump is down, make sure it has the same capacity as the original. Otherwise, the water will eventually reach its limit and overflow.
There are also combination sump pump systems, which combine both the backup and primary into a single unit. If your original pump is nearing the end of its life and you want to ensure that two pumps can fit in the basin, this is an excellent option due to their increased compactness.
2. Power inverter
The first configuration has restrictions. First, you’ll need enough additional room in the pit. Second, you’ll either need to hire a plumber or do some labor yourself. Finally, because most DC backup pumps are designed to work with less than 2500 GPH of water incoming, you’ll need to have less than that coming in.
Power inverters eliminate all three issues by providing your main pump with continuous power regardless of interruptions. When picking an inverter, it’s critical to choose one that includes an auto switch and charger, such as the ones shown above, so that they operate automatically without you having to go down into the basement every time.

If you want a sump pump that will give you some extra peace of mind, the PumpSpy PS2000 is the way to go. It’s also backed by a 1-year warranty, which is shorter than most but still shows that the company stands behind its product.
The controller’s main functions include preventing flood damage, controlling pump action as soon as possible after flooding is detected and before further damage can be caused by the water, monitoring the status of it for you throughout the day to send notifications if something goes wrong, and keeping track of when your sprinkler system was last turned on or off. It does a check every 48 hours to see whether everything is OK so you can react to problems immediately rather than waiting for flooding to occur. If your connection goes down, their server sends you an alert that they cannot reach your pump, which is most likely the case during an outage.
This program is designed to help you monitor every aspect of your irrigation system, from the pump to the sprinklers. It will also track daily pump cycles, last cycle time, estimated gallons pumped, and total cycles by date, giving you a much better picture of your system. The catch is that it costs more than the previous two software programs. Is it worth spending extra money for that peace of mind? That’s up to you to decide.

Things To Consider Before Purchase:
1. Build Quality
The battery backup sump pump and inverter must have outstanding build quality. Before we look at their characteristics and performance, we must ensure that it has an excellent structure with no obvious manufacturing flaws. The pumps must be resistant to corrosion and accumulation while also being robust enough to resist impact and erosion. In the case of the inverter, they should be able to tolerate the dampness in the basement.
Some components, such as the motor housing, must be made of materials that are suitable for their function. Aside from keeping what’s inside safe, the motor housing should also promote heat transfer to keep the engine cool at all times. The float switch on the pump must be puncture- and dirt-resistant as well. The battery box must also be resistant to damage and dirt accumulation.
2. Performance
We need a strong backup sump pump that can keep the water supply from overflowing the pit. It must be able to move nearly as much water as the primary pump in order to provide comparable protection when the primary fails. As a result, you should also choose a backup pump with a similar capacity to your primary one.
Because the battery power is restricted, it must also be highly efficient, which means that it can function for longer on a single charge. You don’t want your battery juice to run out before you get a chance to use it.
3. Features
A sump pump’s battery backup necessitates the use of a complete sump pump kit. As a result, it is generally equipped with a few more surprises in comparison to the primary.
A float switch, in addition to other features such as sensors, alarms, chargers, and indications, may provide you with a clear picture of the system’s current condition. There are also remote alert systems from far more sophisticated pumps like the PumpSpy that might be quite useful for people who have to go away frequently.
4. Ease of Installation
The final factor to consider is the installation. If you want assistance with the installation of backup sump pump systems, plumbers and other experts (you may hire one through TaskRabbit) can assist you. Because so many of us are installing the pump on our own, a simple-to-install pump or inverter is a huge help.
If you don’t have enough space in your basement for a battery-operated sump pump, consider placing it alongside the existing pump. You may need to shift the primary as needed to accommodate the new device.
However, in the long run, inverters are significantly easier to install and will most likely cost less in installation costs if you have to hire someone. All you have to do is hang it on the wall or a raised surface and connect the batteries and connect to the outlet.
Frequently Ask Questions:
What if the electricity goes out for several days?
Because the sump pump battery only lasts for a few hours to a few days, you can’t count on it to keep the basement dry for an extended period of time. There are only two things you can do in advance of something like this happening:
Prepare a spare battery – perhaps the simplest and cheapest way to prepare for a longer power outage. Keep a battery on hand or connect them in parallel.
If your region is prone to extended power outages that last for days, you may use a sump pump generator. The greatest you can do in such an instance is to acquire a generator, so you can run your pump as long as you have fuel. You could also utilize it to keep food cold and the AC operating.
What kind of batteries do you recommend I use with this?
The type of battery that’s ideal for sump pump use is a deep cycle marine battery, and the best option is an AGM-type battery that doesn’t require any attention. It works well with sump pump power requirements.
A battery backup sump pump requires a minimum of a 75 amp hour battery to run for at least 5 hours. Of course, I suggest the 100 AH versions for a longer operating duration.
You could go with two 50 AH batteries in parallel for a total of 100 AH, but I prefer a single 100 AH battery for its longer operating duration and easier maintenance.
What is the warranty like?
The warranty on backup sump pumps varies by manufacturer, but most offer at least a one-year warranty. Some companies offer limited lifetime warranties on their products. If you’re looking for the best possible warranty, check out the Zoeller M53 which offers a 3-year warranty.
How often should I test my sump pump backup system?
I recommend testing your sump pump backup system at least once a year to ensure that it’s working properly. Many people choose to do this before the start of the rainy season.
To test your sump pump backup system, simply pour a bucket of water into the sump pit and see if the pump turns on. If it doesn’t, check the batteries to make sure they’re charged, and then check the connections to ensure they’re tight.

Conclusion:
If you live in an area where power outages are frequent, I would highly recommend investing in a battery backup sump pump system. Not only will it give you peace of mind, but it could also save your basement from flooding.
