Wayne WSB1275 75Ah AGM Sealed Backup Sump Pump Battery Review

If you want to keep your basement flood free, you already know that you need a good sump pump. However, no matter how good your AC sump pump might be, it’ll lose all effectiveness the moment you lose power. To keep your basement dry in the middle of a rain storm, you’ll either need a water-based sump pump or a battery-based sump pump. And to keep that pump running, you’ll need a good battery. Today we’re going to take a look at the Wayne WSB1275 sump pump battery. But before we do, let’s review some of the best battery-based backup sump pumps on the market.

Even if you’re lucky enough to be using an AC sump pump like the Zoeller M267, which is about as reliable as an AC pump gets, you’re still going to be vulnerable to power outages and the flooding that comes with them (unless you’ve got a generator, at least). Barring a generator, you need backup. If you want a battery backup pump, you can choose between DC backup pumps or AC/DC combos. Among the DC backup sump pumps, we prefer the Wayne WSM3300; it’s by far the best on the market. If you’d rather have an AC/DC sump pump, we love the Wayne WSSM40V, the Zoeller 508-0006, and the Zoeller 507-0008. But no matter what you get, it’s important not to cripple it with a bad battery; the best battery-powered pumps won’t work well when hampered by low voltage.

Fortunately, good batteries don’t need to drain your savings accounts. We’ve recently looked at the MK E27-SLD-G and Zoeller AGM; today we’ll review the Wayne WSB1275 75Ah AGM Sealed Lead Acid sump pump battery. and see how it works with the sump pumps we briefly profiled above. If you’re ready to buy it and looking for a seal of approval, we’re here to tell you that it’s a good battery, and you can buy it here.

Key Features of the Wayne WSB1275 Battery (60 Second Summary)

The Wayne WSB1275 is a deep cycle AGM battery designed for sump pump and marine applications. Wayne describes it as maintenance-free, which is par for the course for most deep cycle batteries marketed to consumers today. It means you shouldn’t ever have to top it off or risk seeing or touching battery acid (always a good idea). It has a nominal voltage of 12V, is pre-charged, and designed to provide at least 5 hours of continuous operation for a DC-based backup sump pump. It is 11 inches long, 9 inches tall, and 8 inches wide while weighing in at 49 pounds on our scale. It comes with a 1 year warranty from Wayne. The reserve capacity is 175 minutes and the amp hour rating is 75 (75Ah).

Zoeller AGM Compatibility with DC Backup and Combination Sump Pumps

We were satisfied with the wide range of compatibility we found from the Wayne AGM battery. Wayne stated it’s compatible with all battery backup products they manufacture, and we found this to be true. We first tried it with 3 Wayne DC backup pumps: the WSM3300, the ESP25, and the ESP15, and had success with all three. We then tried it with 3 of their combination pumps and had success and full functionality with the WSSM40V, WSS30V, and WSS20V. We moved on to a number of Zoeller pumps, starting with two of their DC backup pumps: the 508 Aquanot and the 507 Basement Sentry, and found smooth performance. We then tried two o their combination AC/DC pumps, the 508-0006 and 507-0008, and the Wayne passed with flying colors. We didn’t have time to test additional DC dedicated or combination sump pumps, but we’d expect high degrees of compatibility given prior results.

Our Short and Long Term Experiences Installing and Using the  Zoeller AGM Battery

Perhaps the most significant thing to keep in mind about the Wayne WSB1275 is that it doesn’t come with terminal posts. Also known as terminal bolts or terminal ends, these are essential for connecting your battery to your sump pump (the same way the posts on car batteries connect such batteries to cars). We’d recommend picking up a set like these if you plan on buying the Wayne, as not every sump pump package will come with an extra set for you.

Regarding longevity, we’ve had a variety of experiences with the Wayne WSB1275. We’ve seen some installations last past 5 years while we’ve seen a number that fail to hold charges after 2-3 years. In a few bad cases, we’ve seen it fail in under a year (the worst case was at 4 months). Frankly, we wouldn’t use this battery in any critical settings where we needed a battery to reliably work for more than 5 years. Wayne provides a conservative 1 year warranty, and given some of the longevity concerns we’ve heard from others, we wish this warranty were longer. We trust the Zoeller AGM and MK batteries more.

Zoeller AGM Battery Pros, Cons, and Value Comparison

Overall, the Wayne WSB1275 is a good mid-priced battery, but it’s not the best battery out there for a backup sump pump system. It’ll certainly do a better job than most of what you’ll find in your local box stores, but if you can spare a bit more money, we’d recommend either the Zoeller AGM or MK E27-SLD-G instead; our unscientific survey suggests more homeowners and plumbers are squeezing more years out of those batteries than they are out of the Wayne. Of course, batteries are always a mixture of science, art, and plain luck, and it’s possible that you could get a Wayne that gives you many years of service. However, if you don’t want to test your luck, we’d suggest the Zoeller or the MK if possible, and then the Wayne if not. And as a bonus, both of those batteries, unlike the Wayne, come with battery terminal posts.

Zoeller AGM 10-1450 Backup Sump Pump Battery Review

When it comes to basement waterproofing, a good sump pump is essential. But an AC sump pump isn’t enough; you also need something that’ll keep ticking when the power goes out–that either means a water-based pump or a DC-based sump pump. And if you’re going to keep one of those running, you’re going to need a good battery. Today we’re going to take a look at the Zoeller AGM backup sump pump battery. But before we do, let’s quickly review some of the the pumps you might want to use it with.

As noted above, even if you’re using a top AC sump pump (which for us would be the Zoeller M267), it’s not going to do anything for you if you lose electricity in the middle of a thunderstorm. And experience (and Murphy’s law) tells us this is when it’s most likely to happen. So you need some kind of sump pump. If you’re just looking for a DC backup sump pump, our favorite is the Wayne WSM3300; nothing else comes close. If you’re looking for an AC/DC combo, we’re big fans of the Wayne WSSM40V, the Zoeller 508-0006, and the Zoeller 507-0008, in that order. But whatever you get, you don’t want to cheap out on the battery. The best backup sump pump won’t pump a gallon of water if it’s running on a dead box store battery that gave up the ghost a month after you bought it.

Fortunately, you don’t have to spend your retirement funds (or your kids’ college savings) on a good deep cycle battery. Today we’ll take a closer look at the Zoeller AGM backup sump pump battery to judge its compatibility with some of the sump pumps we described above. If you’re ready to buy it and just want to know if it’s reliable, we’re happy to let you know that it is, and that you can buy it here.

Key Features of the Zoeller AGM Battery (60 Second Summary)

The Zoeller AGM is a deep cycle (marine-type) battery particularly suited for sump pump and marine applications. It is described as maintenance-free, meaning you should never need to top it off with fluids or check fluid levels during normal use, as it is fully sealed. It has a nominal voltage of 12V and is designed to provide between 5 and 7 hours of continuous operation for a DC backup sump pump system. It is 7.5 inches tall, 10 inches wide, and 12.75 inches deep. It includes a 1 year warranty from Zoeller. The reserve capacity is 175 minutes while it is rated at 72 amp hours (72Ah).

Zoeller AGM Compatibility with DC Backup and Combination Sump Pumps

We were thrilled with the compatibility of the Zoeller AGM with every DC sump pump we tried. Given its manufacture by Zoeller, we were particularly interested in its functionality with Zoeller sump pumps, and we were not disappointed. It installed seamlessly and maintained a steady charge in two Zoeller DC backup pumps: the 508 Aquanot and the 507 Basement Sentry, and it was fully compatible with the aforementioned pumps when they were packaged into the 508-0006 and 507-0008 respectively. We were also pleased with functionality with a number of Wayne sump pumps, and reported full compatibility with three of their DC backup pumps: the WSM3300, the ESP25, and the ESP15. When it came to combination AC/DC pumps, we also had success with the WSSM40V, WSS30V, and WSS20V. We’ll continue testing it with other backup and combination sump pumps on the market, but initial results are very promising, and we’d expect it to be compatible with virtually every system currently on the market.

Our Short and Long Term Experiences Installing and Using the  Zoeller AGM Battery

Although Zoeller only provides a very conservative 1 year warranty, we have full confidence in the battery’s lasting up to 10 times as long, if not longer. We find the slightly higher price of the AGM more than offset by the dramatically increased longevity in comparison to regular box store deep cycle batteries, which typically die and need replacing within 1 to 3 years. Rather than making such a poor investment of both time and money, we’d rather spend a bit more at the start for a lasting product, and our notes with fellow plumbers and homeowners suggest the AGM is a solid investment. We’d rate the average lifespan of an AGM between 7 and 10 years, although for safety, it’s always good to review a deep cycle battery’s charging and discharging abilities every year.

Zoeller AGM Battery Pros, Cons, and Value Comparison

Overall, the Zoeller AGM is the best battery we’ve tested so far for DC backup and combination sump pump installation. It delivers a strong and consistent power supply and is likely to provide a high degree of both short and long term reliability. It’s far from the cheapest deep cycle battery you’ll find on the market, but we’re firmly of the mindset that you can either pay a bit more and cry only once (and spend the rest of your time smiling with peace of mind) or you can pay a bit less at first and spend a lot more later in both time and money. When your sump pump starts overflowing in the middle of a flash flood with the power out and your backup pump won’t start, the last thing you’ll be thinking of is how good of a deal your cheap battery was. Spend a bit more up front for high-end, proven gear that’ll be there for you when you need it most.
