Deep-cycle marine batteries are designed to provide a steady and long-lasting stream of power that is perfectly suited for powering sump pumps. They are efficient and incredibly dependable, ensuring that your sump pump will have the power it needs when you need it most.
Today, let’s explore the advantages of using a deep-cycle marine battery to power your sump pump. We’ll cover everything from sizing recommendations and runtime estimates to other essential details below, so you can decide whether this is the right option.
Can I Use a Deep Cycle Marine Battery In My Sump Pump: 5 Reasons
Opting for the most suitable battery for your sump pump is critical. This decision may allow it to continue to run even if there is a prolonged power outage. Deep-cycle marine batteries are typically known as the go-to option, offering you numerous perks.
You should use a deep-cycle marine battery for these reasons:
Durability and Longevity
Deep cycle marine batteries have fewer, thicker plates than regular starting batteries, allowing them to discharge and recharge multiple times without significant capacity loss. Additionally, deep-cycle marine batteries have a cycle life or cycle rating, which indicates the number of cycles before capacity is reduced to 80%.
The durability and longevity of these types of batteries make them an excellent choice for sump pumps, as they can be relied on to provide reliable power during a power outage or flooding event.
Ability to Provide Continuous Power
Deep-cycle marine batteries are specifically designed to provide continuous power output. Unlike starting batteries which produce short bursts of high energy, deep-cycle marine batteries will steadily provide energy over extended periods.
Making them particularly useful in the context of sump pumps, whose primary purpose is keeping flooding at bay during a power outage. Deep-cycle marine batteries are ideal for sump pump applications with their continuous power output.
Ability to Handle Deep Discharges
Deep cycle marine batteries are designed to handle deep discharges of up to 80%, while standard starting batteries have a maximum discharge capacity of 50%. This means that if power outages occur, the deep-cycle battery can continue powering the sump pump, whereas a regular starting battery would not.
Furthermore, deep discharges can significantly damage starting batteries and reduce their lifespan. In contrast, a deep-cycle marine battery is built for such deep discharges and so suffers no damage or degradation in performance.
Can Be Recharged Multiple Times
Deep-cycle marine batteries can be recharged multiple times without damaging or reducing their performance or lifespan. This makes them ideal for homeowners who rely on their sump pumps during power outages, as they can be easily recharged after long periods of use.
Also, they have a longer lifespan than other types of batteries due to their ability to withstand multiple charge cycles without degradation in performance.
Resistance to Sulfation
Sulfation is a natural process in lead-acid batteries that occurs when they are discharged below a certain voltage and left for extended periods. This reduces the lifespan and performance of regular batteries, but deep-cycle marine batteries are much more sulfation-resistant.
The result is that they maintain their charge and capacity over long periods, even when subjected to intense cycles of discharging and recharging.
How Big Should a Deep Cycle Marine Battery Be For Sump Pumps?
Choosing the right deep cycle marine battery for your sump pump can be a daunting task, especially if you are not familiar with the technical specifications. The key to making the right decision is to pay attention to the manufacturer’s requirements and specifications.
A battery’s Amp-Hour rating is a critical factor in determining how much energy it can store and its overall longevity. To get the most out of your new purchase, choose one with an AH level as close to maximum capacity as possible, recommended by the manufacturer, for the best results.
For most backup sump pumps, this rating should be around 120 AH, although lower ratings may also be sufficient depending on the specifics of the application. This will ensure that your battery can supply the required power to your sump pump for an extended period without running out of juice during a storm.
It is also essential to consider other factors when selecting a suitable deep-cycle marine battery. These factors include operating temperature range, charge/discharge rate, voltage capacity and power output. It needs to be able to handle frequent discharging cycles and have thermal runaway protection.
