Lion Battery Life Fix

Have you ever wondered how to pick out the best battery(s) for your solar panel system (or off-grid energy system)? Or have you wondered what makes one deep cycle battery greater than another?  If so, this report will answer these questions and give you specific things to check on before purchasing your new battery (to make certain you get the most bang for your buck)!

When picking a battery (or batteries) to your solar panel system, there are three categories of batteries which work best.    We will do this in 2 parts:

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

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

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

So let’s get started…

So the first decision to make is the sort of battery that will fit your system.

Lead Acid Batteries

They are also among the longest-used and most reliable batteries in existence.  When compared with the other batteries we’ll discuss in this report; they are 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 cost, or whether you are simply making the move to a solar panel system, lead acid batteries might be a very good option.  They’re the type of battery we use in the majority of the battery banks in our solar panel systems.

Saltwater Batteries

Saltwater batteries are more expensive than lead acid batteries, but also have a better lifespan.  Unlike lead acid batteries, saltwater batteries are essentially brand new to the market and stay both somewhat untested and more difficult to come across.  Of the 3 types of batteries, saltwater has the greatest depth of discharge, so you’ll get the most output per charge before needing to recharge.

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

Part 2) Compare the elements of batteries.  Once you’ve picked the best battery type for your own solar panel or off-grid system (that meets your system’s needs), there are elements to explore to find the perfect battery to your system.  

Cost

Price is probably one of the more obvious components.  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 might not be the best choice always.

For most systems, a battery will cycle daily, meaning it is going to charge and drain regularly.  With each cycle, the battery’s ability to hold the identical charge lessens slightly.  So one component to consider is the guarantee on the battery that guarantees a certain 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 application, you can extend the life of your batteries.

Length of Discharge

Depth of discharge is how much you can drain the battery before needing to recharge the battery without harming its life.  Certain solar batteries may be depleted farther than others, allowing for more use between charging.  Essentially, a battery with a 90% depth of discharge per cycle provides more battery power per charge than 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 given moment.  A battery with a high capacity and higher power can run a massive system for several hours; a battery with low capacity and high power can operate a large system but just for a short time.

Efficiency

Efficiency is the amount of energy used compared to the amount of energy it took to store energy.  Batteries require power to charge and efficacy compares the energy taken to control a battery with the amount of energy that the charged battery produces. 

Manufacturer

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