To make the generator functional again, it was clear that a better battery was needed. This led me to the question: What are the best generator batteries available? And what factors should one consider when purchasing one?
Choosing the right battery is crucial for powering your Generac 22kW generator effectively. As mentioned earlier, using the wrong or subpar battery would only lead to ongoing battery issues and frustration.
However, with numerous battery options available, it can be challenging to determine the most suitable one for your needs.
But don’t worry, as I have already conducted extensive research, testing, and evaluation to bring you my top choice batteries for your Generac 22kW generator. Allow me to share my selection process and how I arrived at these batteries as the best options.
My Top 3 Choices Batteries for Generac 22kW Generator
Among the batteries recommended for the Generac 22kW generator, three stood out: Generac 5819 Model 26R, EverStart Value Lead 26R, and AC Delco GOLD. Each had its unique features and advantages, and I decided to explore them further.
1. Generac 5819 Model 26R
Being specifically designed for Generac generators, the Generac 5819 Model 26R instantly caught my attention. Its lightweight construction, weighing just 30 lbs, made it the easiest to handle and install. Although it had a slightly lower cold cranking amp (CCA) rating, I was reassured by its easy maintenance and the manufacturer’s endorsement of its compatibility with Generac generators.
2. EverStart Value Lead – 26R
Considering affordability without compromising quality, the EverStart Value Lead 26R was an appealing choice. With better cold cranking amps (CCA) than the Generac 5819, it proved to be suitable for colder conditions. Although it was slightly heavier and had a larger size, its durability and 12-month warranty provided peace of mind. As someone conscious of budget constraints, the EverStart Value Lead 26R became a compelling option.
3. AC Delco GOLD
Intrigued by the advanced technology of AGM batteries, I explored the AC Delco GOLD as a premium choice. AGM batteries are known for their durability and resistance to vibration, making them ideal for generator applications. With an impressive 880 cold cranking amps (CCA) and a remarkable 36-month warranty, the AC Delco GOLD stood out for its outstanding cold cranking ability. Although it was the heaviest option, its affordability and AGM technology convinced me of its superiority.
How Did I Choose These Batteries for Generac 22kW Generator As the Best
When it comes to choosing the best battery for Generac 22kW generators, there are several important factors that I always consider.
These factors ensure that I make an informed decision and select a battery that will provide optimal performance and reliability.
Here’s a closer look at each factor:
1. Battery Weight
Portability is often a priority for me, as I want a battery that is easy to carry and install. Opting for a lighter battery can make a significant difference in terms of convenience.
In my research, I discovered that the Generac 5819 and EverStart Value Lead 26R are among the lighter options available, making them ideal choices for those who value portability.
2. Battery Size
It is crucial to ensure that the battery dimensions align with the compartment size of my generator.
A battery that fits properly will not only be easier to install but also function optimally within the generator.
To determine the right battery size, I always consult my generator’s user manual and carefully compare it with the battery’s dimensions before making a final choice.
3. Capacity and Cold Cranking Amps (CCA)
The battery’s capacity and cold cranking amps (CCA) play an important role in its performance. A higher capacity battery will provide more power, ensuring that my generator can meet its power demands effectively.
Additionally, considering the cold cranking amps is essential, especially if I live in an area with cold weather conditions.
The CCA rating indicates the battery’s ability to start in such conditions. During my research, I found that the AC Delco GOLD battery offers outstanding cold cranking ability among the available options.
A warranty is an important aspect to consider when purchasing a battery. It provides peace of mind and ensures that I can easily resolve any potential issues that may arise.
Among the batteries I’ve explored, the AC Delco GOLD battery stood out with its longer warranty period, giving me confidence in its durability and the manufacturer’s commitment to quality.
Lastly, considering the maintenance requirements of the battery is also important for me.
While some batteries require regular upkeep, others are designed to be maintenance-free, offering convenience and peace of mind.
I always choose a battery that aligns with my maintenance preferences and capabilities. This way, I can ensure that the battery remains in good condition and performs optimally over its lifespan.
