When you look at lithium-ion batteries, you are looking at the latest development for storing solar power.

Lead-acid batteries are still very common and still serve a purpose, but there is no denying that lithium-ion is the future. They are currently the best solution for battery storage, and you are using them in your mobile devices right now.

That is because they are the best type of rechargeable battery on the market.

So, if you are planning on installing a Solar Power system at home and you are weighing your options, this is what you need to know.

Pros & Cons | Brands | Review

Lithium Ion Batteries are distinctly different

Lithium-ion batteries are distinctly different from their lead-acid counterparts. They also provide more advantages in terms of performance and efficiency.

However they are not the perfect solution, yet, but they are popular for several reasons. To help you get a better understanding of lithium ion batteries and why they usually cost a little more.

Here is a breakdown of the pros and cons.


  • Lightweight and Small
    If you were to compare the average lithium-ion battery with an average lead acid battery, you'll notice the former is about one third the weight of the latter. In terms of volume, lithium-ion models are half the size. And given the purpose of the battery along with the fact that you'll be storing it for a very long time, the smaller the better.
  • A Sleek Design
    One of the first things you'll notice is how sleek the designs of lithium-ion batteries are. Unlike lead-acid batteries, you won't have to worry too much about the appearance.
  • More Efficiency
    For quality lithium batteries, the discharge and charging are as close to 100% as you are going to get. This means they can discharge and charge completely without losing amps.
  • Increased Cycles
    Batteries can only go through a certain amount of charging and discharging cycles before they lose capacity and efficiency.
    With lithium, you'll be getting the most possible cycles, averaging about 5000 plus cycles, depending on the battery you choose.
  • Consistent Discharge Voltage
    When lead acid batteries discharge, the voltage becomes inconsistent. But the voltage of lithium-ion batteries stays consistent throughout the discharge process, making it much safer to use in terms of protecting electric components.
  • Competitive Pricing
    Yes, the initial investment for a lithium battery is more than the lead-acid alternative. But when you take the lifespan, ability, and performance into consideration, lead-acid batteries will probably end up costing you more in the long run.
  • Low Maintenance
    Chances are you'll forget the battery is there because it requires very little maintenance.
  • More Environmentally Friendly
    Lithium ion batteries are much more environmentally friendly, meaning you leave a smaller carbon footprint.


As mentioned earlier, lithium-ion is not the perfect solution. It has some drawbacks you want to consider first, and they include:

  • Cost
    While you save money in the long run, it doesn't make the initial investment any less intimidating.
  • Overheating
    You don't want a lithium battery overheating, seeing as it will degrade the efficiency.
