How To Fix Low Temperature Unable To Charge Battery

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

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

Part 1)   Instantly compare the three chief 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 the article you will know exactly how to pick the best battery for your own solar panel system!

So let’s get started…

Part 1) The Three Best Types Of Batteries For Solar Panel Systems: The best type of battery for your solar panel system will be dependent on what you’re looking for. 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 are the most commonly used rechargeable battery in the world. They are also among the longest-used and most dependable batteries in existence.  When compared with the other batteries we will discuss in this report; they’re 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 price, or whether you are just 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 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.  Contrary to lead acid batteries, saltwater batteries are basically brand new to the market and stay both somewhat untested and more difficult to come across.  Of the three types of batteries, saltwater has the best depth of discharge, which means you’ll find the most output per fee before needing to recharge.

Lithium Batteries

Lithium batteries are the most expensive and the longest lasting of the three types of solar batteries.  Comparing all three choices, the lithium ion battery may be the highest rated, but also the most expensive.  An example of a lithium battery is the Tesla Powerwall.

Part 2) Compare the components of batteries.  As soon as 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 for 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 buying batteries as well.  Sometimes though, certain batteries may 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 every 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 specific number of cycles of useful life.  But bear 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

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 store.   Power is how much energy that a battery can provide at a given moment.  A battery with both a high capacity and high power can run a massive system for many hours; a battery with low capacity and higher 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 control and efficiency compares the energy taken to charge a battery with the amount of energy that the charged battery generates. 

Manufacturer

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