Generac 5819 Model 26R:
Best Recommended Battery:
- DC Voltage: 12 V
- Weight – 30 lb
- Cold Cranking Amps – 525
- Warranty – 12 months
- Dimension [ L x W x H] – 8.7 x 6.8 x 7.6 inches

Starting with the Generac 5819 Model 26R wet cell battery, this is the product that has been designed specifically for this generator. It is highly reliable which comes at a weight of only 30 lbs making it the lightest of the options in this list.
Beyond that, it comes with a slightly compact dimension with the smallest width of the options. However, its main lagging factor is the low cold cranking amps (cca). This is an important factor that shows the battery’s ability to start in cold conditions. The higher the cca, the better will be the ability to start in cold. So, unfortunately this is where Generac 5819 slightly lags behind.
But beyond that it has easy maintenance and the installation process is also easy. But the main reason why we believe this will be the best for Generac 22kW generators is that this battery has been designed, tested and built for Generac generators. So, you will get promising results.
EverStart Value Lead 26R:
Most Affordable Product:
- DC Voltage: 12 V
- Weight – 38.2 lb
- Cold Cranking Amps – 540
- Warranty – 12 months
- Dimension [ L x W x H] – 6.9 x 9.1 x 8.9 inches
- Relatively Lightweight
- Most affordable option
- Has the largest width which can be a limiting factor based on generator size
- Has issues related to reliability especially in places with heat and moisture
EverStart Value Lead shines where Generac lags behind. It is the best option for an affordable product range with each piece coming only at about $65. The batteries also have better cold cranking amps than Generac which makes it an optimal choice for colder conditions.
However, it is slightly heavier and has the highest width among all the other options. It also has the highest height among all the options. So, overall Everstart Value Lead 26R is a large size option. But you do not need to worry about maintenance and installation. In terms of durability you get top notch and a 12 months warranty.
Whether you are thinking of adding multiple power switches to the generator or get the most affordable product, EverStart Value Lead will be a good option.
So, if you are someone who is tight on budget but wants a reliable battery for your 22 kW Generac generator then go for EverStart Value Lead 26R.
AC Delco GOLD:
Best AGM Battery:
- DC Voltage: 12 V
- Weight – 45.5 lb
- Cold Cranking Amps – 880
- Warranty – 36 months
- Dimension [ L x W x H] – 11.9 x 7.5 x 7.6 inches
- Relatively affordable
- Has the best cold starting ability
- Has the highest warranty
- Has the most battery weight
- Has the largest length
This is the only battery in the list that is AGM and not a lead cell battery. AGM are basically advanced lead acid batteries that contain an absorbent glass mat and fine glass separator between the positive and negative plates. This separator helps to absorb the battery acid. This feature makes the battery more durable and also more resistant to vibration.
If you want a battery to perform properly inside a generator then it must be able to endure vibration. So, this is a feature that comes in handy. Moreover it has the highest warranty in the list. Regardless, you may want to watch out for any problem with the generator especially if the red light turns on.
In terms of overall cold cranking you get the best result from AC Delco Gold. However it lags slightly behind in terms of its weight. It is the heaviest option in the list. But beyond that, it is also relatively affordable.
So, if you are looking for a battery option that is AGM and will come with the best cold cranking result along with affordability then choose AC Delco Gold.
How To Choose the Best Battery for Generac 22kW Generator?
Before you go on to buy the best battery for Generac 22 kW generator, you need to consider a few important factors. Let’s go through each.
Battery weight is an important factor. Normally if you want to move around the battery for maintenance or replacement then a lighter battery will be easier to carry. From the product list this is where Generac 5819 and EverStart Value Lead shines.
Battery size is another crucial factor that you need to keep in mind. This is because you need to be sure that the battery actually fits properly in the generator compartment. So make sure to go through the user manual to find the compartment size and while buying the battery look for its dimension.
Battery capacity is another factor you need to check. It shows how much is the total amount of electrical current generated due to the electrochemical reaction inside the cells. More capacity means there will be more power and more efficient will be the generator performance.
In some cases, you will come across terms like cold cranking amps, which means the ability of the battery to function normally in extreme cold conditions.
Product life warranty is another important factor for the battery. If the battery comes with a good life warranty then you will be relieved to find out that despite any problem, you can get it fixed anytime you want. This is where AC Delco Gold takes the prize among the options in the list. Make sure to check the warranty before you make the final purchase.
Finally, you need to check the maintenance requirement for the battery. Some of the batteries require a lot of maintenance. In this case you need to regularly keep track of the water levels and clean the terminals. But in most cases you will find batteries do not require maintenance on a regular basis.
So make sure to check the overall maintenance requirement for the battery. If you buy a high maintenance battery, then check for the steps required to keep it functioning properly.
