Liberty Pumps 441 Battery Backup Sump Pump
The next battery backup sump pump on our list is the 441 backup sump pump from Liberty Pumps. If it’s an easy to set up, well-performing sump pump you require, this one could be well worth looking at.
Like the other units on our list so far, this pump also uses a 12V battery to operate. However, this one also has a 5-stage charging system.
With the system, you’ll receive a battery box, plumbing connections, and an easy-to-connect terminal block.
Liberty Pumps has designed this backup system to work brilliantly with most primary sump pumps, but it performs best when working with a 120-volt pump. Unfortunately, the battery for this doesn’t come with your original purchase.
In terms of durability, the 441 sump pump has been built-to-last. Made from durable thermoplastic, you can rest assured that the pump will work for many years to come.
Aside from a solid performance and neat control panel, the thing we were pleased with most with this pump was the fact it comes pre-assembled.
This makes your life a lot easier when it comes to setting the pump up. This is particularly useful if you have no prior experience working with a sump pump.
Pros
- Pre-assembled – This backup pump arrives pre-assembled.
- Lightweight – The 441 sump pump only weighs 13 lbs.

We appreciated the sound alarm that comes with this pump. When the pump is active, an alarm will sound to notify the homeowner that pumping has begun. You can also see system readiness on the smart LED display.

Buyer’s Guide
Before making your final decision in regards to which battery backup sump pump you need to buy, there are a number of important things you need to take into consideration. By not taking these things into account, you could easily make the wrong choice when picking a sump pump out.
To help you out, we’ve put together this short buyer’s guide that looks at the most important things you need to think about. By taking each point we make into account, you’ll be able to make a decision you can be pleased with.
Size
One of the most important factors to take into account is the size of the sump pump you need. You need to determine how much water the backup pump needs to be able to remove from your house per hour as well as how much space you have in your basement.
Generally speaking, a sump pump is installed into a sump pit below floor level. This means the pump will operate 10 feet high in order to remove the water. In regions with more downpours, the pump will need to remove more water per hour.
For example, in areas where frequent floods are common, a pump that can remove 2,600 gallons of water per hour is much more appropriate than one that only pumps 1,000 gph.
When considering space, you need to ensure you physically have room in your basement for the pump. If your basement is only small, you’ll need a pump with a smaller configuration.
On the other hand, if your basement is larger, it might be a good idea to choose a bigger pump.
Durability
Taking durability into account is absolutely crucial.
The last thing you need is a sump pump backup that fails on you just when you need it most. You’re also going to want your sump pump to last for many years, so if it isn’t durable enough, you’re going to feel let down very quickly.
Luckily, finding the most durable battery backup sump pumps isn’t too difficult. All you need to do is look out for ones that are made out of solid materials. By far the most durable type of pump you can buy is one made out of cast iron.
These pumps should last for several years if not more when correctly maintained. Stainless steel and epoxy-coated stainless steel pumps are also very reliable and durable.
Alarm
While it may not be super important, you might want to consider choosing a battery backup sump pump that comes with an alarm feature. Having an alarm built-in to the pump is incredibly useful because it notifies you whenever the pump is active.
This alarm feature is also very useful because it tells you when any maintenance needs to be carried out and the status of the battery. Some pumps will not only alarm you but also solve any maintenance issues automatically after grabbing your attention.
Battery Life
Seen as though battery backup sump pumps run off battery power, you’re going to have to think carefully about how effective the battery is.
Ideally, you don’t want to end up in a situation where you have to charge the battery two or three times a week. Instead, you should try and find a battery that only needs charging once a week after intense pumping.
A pump with a longer battery life will be able to pump water out of your basement for longer periods of time. This will result in more water being pumped out, keeping your basement dryer in the process.
Look for pumps that are capable of pumping around 10,000 gallons of water before needing to be recharged if possible. Alternatively, look at units that can keep pumping for hours or even days when necessary.
You might also wish to look for pumps that come with smart battery technology. These units will have a fully optimized battery.
