How To Fix Battery Acid Damage

Have you ever wondered how to pick out the best battery(s) to 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 ensure you get the most bang for the buck)!

When choosing a battery (or batteries) for 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 components of batteries, such as: depth of discharge, power and capacity, efficiency, battery life, and maker.

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

So let’s begin…

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

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 lots of storage for a lesser cost, or if you are simply making the transfer to a solar panel system, lead acid batteries may be an excellent option.  They’re the sort of battery we use in most of the battery banks within our solar panel systems.

Saltwater batteries are more expensive than lead acid batteries, but also have a greater lifespan.  Contrary to lead acid batteries, saltwater batteries are basically brand new to the market and remain both somewhat untested and more difficult to come across.  Of the three types of batteries, saltwater has the greatest depth of discharge, which means 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 ion battery is the Tesla Powerwall.

Part 2) Assess the components of batteries.  As soon as you’ve picked 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 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 may not be the ideal 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 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 in the EZ Battery Reconditioning program, 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 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 compared to 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 certain moment.  A battery with a high capacity and higher power can run a massive system for several hours; a battery with low capacity and higher power can run a large system but only for a brief 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 charge and efficacy 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 might not be a component most would consider, but it is something to focus on.  As with other technology, there are both reputable brands and startup brands.  A trusted brand includes known flaws and advantages; a start-up brand can perhaps have better technology, but could also have unknown technological difficulties.  Based on your system needs, you might decide to go with a well-reviewed firm or one that is brand new to the market.
