Iphone 4S Battery Life Fix Settings

Or have you wondered what makes one deep cycle battery greater than another?  If so, this report will answer these questions and provide you specific things to check on before buying your new battery (to make certain you get the most bang for your buck)!

When picking a battery (or batteries) for your solar panel system, there are 3 categories of batteries which work best.    We will do this in two parts:

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

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

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

So let’s get started…

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 type of battery that will fit your system.

Lead Acid Batteries

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 cost for some battery life and depth of discharge.  But for homeowners needing lots of storage for a lower price, or if you are simply making the transfer to a solar panel system, lead acid batteries may be a very good option.  They’re the type of battery we use in most 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 basically brand new to the market and remain both somewhat untested and harder to come across.  Of the three types of batteries, saltwater has the greatest 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.  Their depth of discharge is less than that of a saltwater battery, but more than that of a lead acid battery. Comparing all three options, the lithium battery is probably the highest rated, but also the most expensive.  A good 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 components to explore to find the perfect battery to 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 as well.  Sometimes though, certain batteries could be overkill for your system so the most expensive battery may not be the best choice always.

Battery Life and Warranty

For most systems, a battery will cycle daily, meaning it will charge and drain regularly.  With every cycle, the battery’s ability to maintain the same charge lessens slightly.  So 1 component to consider is the warranty 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

Length of release is how much you can drain the battery down before needing to recharge the battery without damaging its life.  Certain solar batteries can be depleted further 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 store.   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 large system for many hours; a battery with low capacity and higher power can operate a large system but just for a short time.

Efficiency

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

Manufacturer

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