What To Consider To Buy The Best Group 24 Deep Cycle Battery?

Dimension

Battery groups were introduced to standardize the dimensions of batteries, making it easier to choose the correct replacement.

In the case of a Group 24 battery, the standard size is 260 x 173 x 225 mm (10 1/4 x 6 13/16 x 8 7/8).

It’s important to note, though, that there may be different sizes and terminal locations within a group. Group 24 batteries are one such case, with five different versions, as shown in the table below

AH Rating

The Ah rating of a battery is not specified by its BCI group. However, the battery size limits how much power the battery can provide. Instead, the Ah rating relies more on the type of battery and the manufacturer’s specification.

A typical lead-acid group 24 battery provides around 75 to 85 Ah, compared to a deep-cycle version that averages 80 to 85 Ah.

Warranty From Famous Brands

Depending on the type of battery, the purchase cost can be high, so a good warranty is essential. Warranty lengths vary from brand to brand and even between different batteries within a brand.

As a guide, average warranties from some famous brands are listed below

Weize 12V 75AH
4.6
At just $149, the Weize 12-volt, 75 Ah deep-cycle battery will satisfy most needs, giving years of reliable service and great value for money.

Why Should You Buy The Weize AGM?

Designed as a deep-cycle battery, running appliances for many hours off the grid, the Weize also provides 1100 amp discharge for up to five seconds. This is ideal for electrical items that need a high startup current, such as fridges and pumps.

Many users bought the Weize to power their RV or trolling motors. The 75Ah version reviewed here easily lasts for eight hours on a single charge, powering lights or a small motor.

The Weize matches the standard group 24 measurements, so it simply slots into your current battery box with no alterations.  

The only downside of the Weize is its short one-year warranty, but in general, they last many more years from checking buyer reviews.

Pros

  • Perfect fit for a group 24 battery box
  • Rugged ABS outer to protect the battery from damage and vibration
  • High surge output for starting pumps and motors

Cons

  • Short one-year warranty

This sealed for life AGM battery will give you years of reliable, maintenance-free service at a price that is hard to beat.

Why Should You Buy The Mighty Max AGM?

At just under $160, the Mighty Max 75 Ah AGM battery is almost half the price of the ACDelco yet offers similar performance.

Although Mighty Max doesn’t state the reserve capacity for their battery, it is around 120 to 140 minutes from the figures they do quote.

Users report that the battery lasts all day or up to 24 hours of switched use with low power devices, such as small pumps and trolling motors.

The only real downside to the Mighty Max is the short one-year warranty. Most users report that the battery easily lasts several years of continuous use.

If you need to return a faulty battery, make sure you keep all the original packaging, as it is a condition of the guarantee.

Pros

  • Competitive price
  • AGM technology 
  • Good reserve capacity

Cons

  • Only a one year warranty
  • Reserve capacity not stated

Verdict

The Mighty Max is perfect for anyone looking for a well-priced group 24 deep-cycle battery. The Mighty Max should give years of reliable service with a good reserve capacity and quality build.

Universal Power Group 24 12V 75AH Battery

<br />
Universal Power Group UB12750

Universal Power 12V 75AH
4.6
They have designed the Universal Power Group UB12750 for mobility scooters using group 24 batteries. Still, it’s perfect for any deep-cycle application, such as trolling motors or small water pumps.

Why Should You Buy The  Universal Power Groups AGM, UB12750

The UB12750 AGM battery is in the mid-price bracket, fitting neatly between the Weize and ACDelco versions, at around $185.

For the money, you get an AGM battery with great deep-cycle capacity, making it ideal for many uses.

Although Universal Power Group designed the UB12750 as a mobility scooter battery, it works perfectly well in any environment that requires a low continuous power supply.

It is slightly taller than a group 24 standard battery, but this won’t be an issue in most cases. Battery boxes often have a small amount of extra vertical space, so it is something to check before ordering.

They also fit the Universal with a helpful grab handle for easy handling, a feature often overlooked.

Pros

  • Good value for money
  • Maintenance-free
  • Useful grab handle

Cons

  • Only a one-year warranty

Verdict

Overall, the Universal Power Group UB12750 is an excellent replacement for any deep-cycle battery where a group 24 battery is required. 

NorthStar NSB-AGM24M AGM

<br />
Northstar NSB-AGM24 Battery

Northstar Group 24 AGM
3.8
The Northstar NSB-AGM24 is hard to beat for long-lasting, reliable power, and the four-year warranty gives you great peace of mind.

Why Should You Buy The Northstar NSB-AGM24?

Let’s get the negatives out of the way first. The Northstar is expensive. At over $600, you could buy four of the Weize batteries and still have change leftover.

So what positives outweigh this cost?

First, a brand name you know and trust. This is important to some people. Second, Northstar offers a four-year warranty, giving you peace of mind and your investment.

But what else? With a cold cranking amps (CCA) rating of 840 and a reserve capacity of 160 minutes, the Northstar is the most powerful battery.

In addition, you can recharge the battery at least 900 times from 50% discharge before the capacity begins to deteriorate. 

The improved power characteristics of the Northstar are due to quality internal components and design.

However, there is a financial and weight cost, as the Northstar is the heaviest on the test at 58 pounds.

Pros

  • Four-year warranty
  • At least 900 recharge cycles
  • 840 CCA
  • 160 minutes RC

Cons

  • Very expensive
  • Weighs 58 pounds – the heaviest on the test

Verdict

If you are looking for the best group 24 battery, the Northstar should be top of your list regardless of cost. The four-year warranty is also a valuable addition.

ACDelco M24AGM AGM

ACDelco M24AGM
ACDelco M24AGM Group 24
4.5
The ACDelco Professional Marine group 24 battery is a reliable deep-cycle battery that requires no maintenance and gives 140 minutes of reserve capacity.

Why Should You Buy the ACDelco M24 AGM?

The deep-cycle ACDelco M24 AGM offers 75 Ah of power in the perfect group 24 size of 10.25 x 6.75 x 8.75 inches.

Add to this the excellent reserve capacity (RC) of 140 minutes, and it’s a battery that will keep your systems working while you have no main power connection.

Internally, the company has used the absorbed glass matt (AGM) technology to produce a battery allowing 900 discharge cycles. This easily beats standard flooded acid batteries, which generally offer only 300 cycles. 

The ACDelco features a built-in carry handle, which may not seem like much on its face, but batteries are heavy old lumps to haul about.

If you need to move your battery often, this feature will undoubtedly be welcome. While we are on weight, the ACDelco is the lightest battery here, weighing in at 45.67 pounds.

Most users are happy with their purchase, but one noted that connection wing nuts were not supplied, so remember to keep the old nuts when you remove your dead battery.

Pros

  • Reserve capacity of 140 minutes
  • Built-in carry handle
  • The lightest battery on the review
  • Three-year warranty

Cons

  • One of the most expensive recommended products
  • Cable connection nuts not supplied

Verdict

Buy the ACDelco if you look for a brand-name battery with excellent performance and a good warranty.

Recommendation

The Northstar is the best group 24 battery on paper, with the highest power and a four-year warranty. The downside, though, is the eye-watering price compared to the competition. For that reason, it is not one of our recommended batteries.

Northstar Group 24 AGM

Rating

For the budget-minded, then the Weize is hard to ignore. It provides all the power you need for just over half the price of the ACDelco and a quarter of the cost of the Northstar.


Weize 12V 75AH

Rating

Instead, if you want a powerful battery with a good warranty, consider the ACDelco. It offers performance close to the Northstar and has a three-year warranty at less than half the price.
