Sump Pump Battery Cost Factors
The cost of a backup battery for your sump pump may seem expensive, but you can budget for it by figuring out the type of battery, pumping capacity, package features, material type, and the labor costs needed to install it.
Type of Battery
There are a few different types of batteries to choose from when purchasing a sump pump battery backup. AGM, or absorbent glass mat, batteries come in standard or deep-cycle designs.
Battery Type | Cost | Lifespan |
---|---|---|
Standard Design | $100 – $200 | 3–5 years |
Deep-Cycle Design | $200 – $400 | 10+ years |
A standard lead-acid battery is often less expensive and offers a high amount of electricity. However, they don’t last as long as deep-cycle batteries. The more expensive deep-cycle or marine batteries have a longer run time which is great during long power outages. With proper maintenance, these batteries can last for 10 or more years.
Pumping Capacity
Depending on your home’s requirements, you’ll need to choose between a high-capacity or low-capacity backup.
Pumping Capacity | ||
---|---|---|
Low-Capacity | $200 – $400 | 1,000 |
High-Capacity | $400+ | 2,200 |
A low-capacity backup is more cost-efficient, however, it can only pump up to 1,000 gallons per hour. A high-capacity backup is more costly but offers a higher pumping capacity, which means it’s faster at removing water from the area.
Additional Parts
Depending on the sump pump backup system you buy, there may be some additional parts you’ll still need to purchase. Some systems do not include the battery, which can cost between $120 to $200 when purchased separately. The initial package doesn’t usually include a discharge pipe or a check valve either, which can cost between $10 to $40.
System Part | Average Cost |
---|---|
Battery | $120 – $200 |
Discharge pipe | $10 – $50 |
Check valve | $10 – $40 |
Build Materials
A battery backup for your sump pump can be made from cast iron, stainless steel, or plastic. The more durable materials often have a higher price point, but they can withstand more severe conditions and have a longer lifespan.
Cast Iron | Stainless Steel | Plastic |
---|---|---|
$100–$2,600 | $200–$600 | $50–$500 |
Long life span | Medium life span | Short life span |
High durability | Medium durability | Low durability |
A cast-iron backup system is the most durable and can outlast severe weather conditions. A stainless steel system is also highly durable and corrosion-resistant. A plastic system has the lowest cost, the shortest lifespan, and less durability.
Labor
When hiring a local sump pump pro to install your system, expect to pay between $45 to $200 an hour. Due to the complexity of a battery backup sump pump system, it can often cost more to install than a system without a battery backup.
