How To Select Battery Backup for Existing Sump Pump

There are a number of things you need to know and consider before purchasing a battery backup for a pump that already exists in your sump. These features or things will determine the efficiency of your product.

Power

If your product comes with a battery of 12V/75 Amps, it is sure to deliver 2000 cycles while having a full charge. However, the number of cycles will vary if it is partially charged.

A battery backup can provide power for almost 5-6 hours without stopping; however, it depends on the current setup of the sump pump. If your pump features auto turn on/off, the backup may last for as many as two days.

Build Quality

It’s more or less evident that your battery backup sump pump must come with a build-quality that will enable it to provide years of operation. The product you choose should feature parts that are resistant to corrosion and strong enough to endure erosion and impacts.

A battery backup should offer individual parts made only to serve specific purposes. For instance, the motor housing should not only protect the components inside but also feature heat transfer, allowing the pump to remain cool during heavy workload.

On the other hand, the battery box should be durable enough to keep the battery protected from outside impacts. Also, the pump should come with a float switch, which can resist dirt accumulation and punctures.

Battery Backup Size

It is obvious that the sump pit in your basement will have limited space. It won’t be able to hold pumps of every size unless the pit is a huge one, which usually is not the case. So, before buying a battery backup pump, make sure you have enough space in the pit.

You also consider the size of the entire sump pump system. Some pumps take up a lot of space due to their unique configuration. However, if you do not have room for the existing pump and another backup pump, you can always buy a separate battery backup and squeeze it with the current machine.

Features

In case you are going for a battery back sump pump, you should pick one that comes with additional features. Usually, pumps come with a vertical float switch. But when you are buying a backup, make sure it has something more to offer.

For instance, chargers, alarms, sensors, and indicators, which show the status of the machine, can always be an excellent addition to the system.

Backup Charging

The sole purpose of buying a battery backup is to avert problems that happen due to frequent power outages. While a backup is extremely useful in such cases, you should make sure it is being charged properly. Therefore, you have to keep an eye on the voltage at times.

You can also decide on a larger battery that requires less charging, but it will cost you more. Recently, some people are relying on solar panels to charge their battery backups. It is a good way to save some extra electricity bills in the long run, but setting up the system will cost you a decent amount of money.

Installation Process

The battery or the backup pump should feature an effortless installation system. Usually, people prefer setting up the sump pump on their own, but you can also hire a plumber. Hiring a professional will cost you some extra bucks; therefore, it is best if you look into something that features ease of installation.

In order to have an effortless installation process, you need to consider the recommended basin size, dimension, cord length, weight, and discharge connection. You should also check if it comes with a detailed user manual.

Types of Battery

Although there are several types of batteries out there, it is best if you go for an AGM or Absorbent Glass Mat battery. AGM batteries are highly suitable for the latest backups. You can also try out Marine batteries and Wet Cell, but they often explode and requires regular maintenance.

On the other hand, AGM batteries require less to no maintenance, and they are quite famous for their longevity. Hence, we recommend you purchase AGM batteries instead of the other ones.
