Lithium vs lead acid vs gel batteries

Recently we’ve seen a growth in popularity and requests for lithium-ion batteries instead of lead acid batteries when it comes to solar storage systems in the Northern Rivers. Many of our competitors have simply decided on other battery types and this includes gel too. We want all our battery power solutions customers to know that the technology is always advancing, and nothing should be left out of consideration. We have broken down all the advantages of each battery type and you can decide what will work best for you…

How do solar batteries work?

You should consider installing a solar battery in collaboration with a new solar power system. You can use it to store excess solar energy that is generated instead of sending it back to the grid. If you are a client that has panels that are producing more solar power than you need, then you need a battery unit to be charged as an alternative power source. When your solar panels aren’t working in the best shape due to environmental issues, you can use your stored energy to power your property when you need it. The electricity will be redirected to the grid only when your battery is full or take more from the grid only when the battery is low.

Several types of batteries

High functioning batteries for energy storage in Northern Rivers typically include lead acid, lithium, and gel. You should focus on selecting the best battery for your solar system needs. This can include things like how much maintenance you are up to keeping up with. Here are some of the differences between lead-acid vs. lithium-ion batteries:

Advantages of lithium-ion batteries

They are the best for solar storage 

Lithium-ion batteries are growing in popularity because they are now the best battery type for general energy storage application due to the high energy density and efficiency. There are many types of lithium batteries available on the market to solar users in the Northern Rivers. Most lithium batteries used for energy storage use lithium iron phosphate cells and that makes them better at lasting for longer and storing more power. 

  • They are easy to use and relatively minimal maintenance
  • Lithium-ion chemistry is high-performing and an ideal for high-power applications.

Advantages of lead acid batteries


Most reliable battery types

Lead acid batteries are still a considerable contender in the solar storage market because they have been around for a century, and they are a well proven technology type that is known to be reliable. Larger off-grid systems may require the use of a lead acid battery because they can last for ten years or even fifteen years. 

  • Age-old technology 
  • 15 years and more lifespan
  • Easy to recycle 

Advantages of gel batteries

Low-acid battery options 

Gel batteries are called gel because they use silica, or sand, in the formula to turn the acid inside the battery into a thick liquid. This makes it the safest battery to use because it won’t spill and expose you to dangerous toxins. This also means that the battery is fragile and therefore shouldn’t be put under high-pressure situations like quick charging, high discharge, or other intense situations likely to cause serious damage to a gel battery, making it fail even if it’s barely used. Gel batteries are more versatile than other types because they can work in a variety of temperatures from extremely high to exceptionally low. This means that they might last longer in hot weather applications than other batteries.

  • Maintenance free
  • Leak proof battery
  • Rechargeable with a proper Battery Charger
  • Easy Operation in Most Temperatures

Solar batteries are always a smart investment for energy storage. The investment in them may get you closer to complete independence from the national power grid. For power grid work, you should always use a level 2 electrician. Without a battery bank supplementing your solar panels, you won’t be able to store energy for later use. If you plan to live completely off the grid, your system simply won’t work at all. These are things you need to consider about the cost of a solar battery:

  • Price: batteries with a low price might look good for the pocket but will come at expense of quality and battery life. You may need frequent battery replacements over time. 
  • Capacity: Higher capacity batteries are more expensive, but it is important because it’s a measure of the amount of energy stored
  • Required lifespan : Different battery types from varying manufacturers may have the same capacity and energy content and be similar in weight. But at the end of the day, they won’t all perform the same for the same amount of time. Their quality and materials could change how long the battery can cycle for.

If you speak to a solar power expert at Cave Electrical & Solar, you may be able to explore your options for fewer solar panels at installation, thanks to higher battery capacity with a lithium model. We can also help you with the regular maintenance of your panels and other electrical services.
