Samsung Galaxy Note 4 Battery Fix

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 ensure 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 two parts:

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

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

By the end of the article you will know just how to pick out the best battery to your solar panel system!

So let’s get started…

So the first decision to make is the type 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 reliable batteries in existence.  Compared to the other batteries we will discuss in this report; they’re the cheapest option but you trade price for some battery life and depth of discharge.  But for homeowners needing lots of storage for a lesser cost, or whether you are just 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 within our solar panel systems.

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 types of batteries, saltwater has the best depth of discharge, which means you’ll get the most output per charge 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 choices, the lithium battery may be the highest rated, but also the most expensive.  A good example of a lithium ion battery is the Tesla Powerwall.

Part 2) Compare the elements 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 components to research to find the ideal battery for your system.  

Cost

Price is probably one of the more obvious elements.  But the old saying,”you get what you pay for” holds true when purchasing batteries also.  Sometimes though, certain batteries could be overkill for your system so the most expensive battery might not be the best choice always.

Battery Life and Warranty

For many systems, a battery will cycle daily, meaning it will drain and charge regularly.  With each cycle, the battery’s ability to maintain the same charge lessens slightly.  So 1 component to consider is the guarantee on the battery that guarantees a certain number of cycles of useful life.  But keep in mind that when 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

Length of release 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 will provide more battery power per charge than a battery with less.

Ability 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 high power can run a large system for many hours; a battery with low capacity and high power can run a large system but only for a short time.

Efficiency

Efficiency is the amount of energy used compared to the amount 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 which the charged battery produces.  The higher the efficiency, the more cost-effective the battery.

Manufacturer

This may not be a part most would consider, but it’s something to pay attention to.  As with other technology, there are both trusted brands and startup brands.  A trusted brand includes known defects and advantages; a start-up brand can perhaps have better technology, but could also have yet unknown technological issues.  Depending on your system needs, you might decide to go for a well-reviewed firm or one that is brand new to the market.
