Mavic Pro Battery Cell Broken Fix

Or have you wondered what makes one deep cycle battery better than another?  If so, this report will answer these questions and provide 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 which work best.    We will do this in two parts:

Part 1)   Quickly compare the three main kinds 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 conclusion of this article you will know just how to pick out the ideal battery for your own 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 are also one of the longest-used and most reliable batteries in existence.  Compared to the other batteries we’ll 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 a great deal of storage for a lower cost, or if you are simply making the transfer to a solar panel system, lead acid batteries might be an excellent option.  They’re the sort 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.  Contrary to lead acid batteries, saltwater batteries are basically brand new to the industry 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 find 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 options, the lithium battery may be the highest rated, but also the most expensive.  An example of a lithium ion battery is the Tesla Powerwall.

Part 2) Assess the components of batteries.  Once 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 for your system.  

Cost

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

For many systems, a battery will cycle daily, meaning it will charge and drain regularly.  With each cycle, the battery’s ability to maintain the identical charge lessens slightly.  So 1 component to consider is the guarantee on the battery that guarantees a specific number of cycles of useful life.  But keep in mind that if you use the maintenance and reconditioning methods we teach you in the EZ Battery Reconditioning application, you can extend the life of your batteries.

Depth 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 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

Measured in kilowatt hours (kWh), capacity is the amount of energy a battery can store over time. The more capacity a battery has, the more power it can save.   Power is how much energy a battery can provide at a certain moment.  A battery with both a high capacity and high power can run a large system for several 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 save said energy.  Batteries require power to charge and efficacy compares the energy taken to charge a battery together with the amount of energy that the charged battery generates. 

Manufacturer

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