How To Fix Macbook Air Battery

Or have you wondered what makes one deep cycle battery better than another?  If so, this article will answer these questions and give you specific things to check on before purchasing your new battery (to ensure you get the most bang for your buck)!

When choosing a battery (or batteries) to your solar panel system, there are 3 categories of batteries that work best.    We’ll do this in 2 parts:

Part 1)   Quickly compare the three main types of solar batteries (lead acid, saltwater, and lithium).   And,

Part 2)   Compare the components of batteries, such as: depth of discharge, capacity and power, efficiency, battery life, and maker.

By the end of the article you will know just how to pick the ideal battery for your own solar panel system!

So let’s get started…

Part 1) The Three Best Types Of Batteries For Solar Panel Systems: The best type of battery for your solar panel system will depend on what you’re looking for. There are three battery types that work exceptionally well; however, each battery type has pros and cons. So the first decision to make is the sort of battery that will fit your system.

Lead acid batteries are the most commonly used rechargeable battery in the world. They’re also one of the longest-used and most dependable batteries in existence.  Compared to the other batteries we will discuss in this report; they’re the cheapest option but you exchange cost for some battery life and depth of discharge.  But for homeowners needing a great deal of storage for a lesser price, or if you are just making the move to a solar panel system, lead acid batteries might be an excellent option.  They’re the type of battery we use in most of the battery banks within our solar panel systems.

Saltwater Batteries

Saltwater batteries are more expensive than lead acid batteries, but also have a greater lifespan.  Unlike lead acid batteries, saltwater batteries are essentially brand new to the industry and stay both somewhat untested and harder to come across.  Of the three kinds of batteries, saltwater has the best depth of discharge, so you’ll get the most output per fee before needing to recharge.

Lithium Batteries

Lithium batteries are the most expensive and the longest lasting of the three kinds of solar batteries.  Comparing all three options, the lithium ion battery is probably the highest rated, but also the most expensive.  An example of a lithium battery is the Tesla Powerwall.

Part 2) Assess the components of batteries.  As soon as you’ve chosen the best battery type for your solar panel or off-grid system (that meets your system’s needs), there are elements to research to find the ideal battery to your system.  

Cost

Cost is probably one of the more obvious elements.  But the old saying,”you get what you pay for” holds true when purchasing batteries as well.  In some instances though, certain batteries could be overkill for your system so the most expensive battery may not be the best choice always.

For many systems, a battery will cycle daily, meaning it is going to drain and charge regularly.  With every cycle, the battery’s ability to hold the same charge lessens slightly.  So one component to consider is the guarantee on the battery which guarantees a specific number of cycles of useful life.  But bear in mind that if you use the maintenance and reconditioning methods we teach you at the EZ Battery Reconditioning program, you can extend the life of your batteries.

Length of Discharge

Depth of discharge is how much you can drain the battery down before needing to recharge the battery without damaging its life.  Particular solar batteries may be depleted farther than others, allowing for more use between charging.  Basically, a battery with a 90% depth of discharge per cycle provides more battery power per charge compared to a battery with less.

Capacity and Power

The more capacity a battery has, the more power it can save.   Power is how much energy that a battery can provide at a certain moment.  A battery with both a high capacity and higher power can run a massive system for many hours; a battery with low capacity and higher power can operate a large system but only for a short time.

Efficiency

Efficiency is the amount of energy used compared to the quantity of energy it took to store said energy.  Batteries require power to charge and efficiency compares the energy taken to charge a battery together with the amount of energy that the charged battery generates.  The higher the efficiency, the more cost-effective the battery.

Manufacturer

This may not be a part most would consider, but it is something to pay attention to.  Like other technology, there are both trusted brands and start-up brands.  A trusted brand includes known flaws and benefits; a startup brand can perhaps have better technology, but can also have yet unknown technological difficulties.  Based upon your system needs, you may decide to go with a well-reviewed company or one that is brand new to the market.
