How To Fix Car Battery Not Charging

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 better than another?  If so, this report will answer these questions and provide you specific things to check on before buying your new battery (to ensure you get the most bang for the buck)!

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

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

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

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…

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. So the first decision to make is the sort of battery that will fit your system.

Lead Acid Batteries

They are also among the longest-used and most dependable batteries in existence.  When compared with the other batteries we’ll discuss in this report; they are 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 lower price, 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 sort 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 essentially brand new to the market and stay both somewhat untested and harder to come across.  Of the 3 types of batteries, saltwater has the greatest 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 types 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 choices, the lithium battery may be the highest rated, but also the most expensive.  A good example of a lithium 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 explore to find the ideal battery to 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 as well.  Sometimes though, certain batteries could be overkill for your system so the most expensive battery might not be the ideal choice always.

Battery Life and Warranty

For most systems, a battery will cycle every day, meaning it is going to drain and charge regularly.  With every cycle, the battery’s ability to hold the identical charge lessens slightly.  So one component to consider is the guarantee on the battery which 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.

Depth of Discharge

Length of release is how much you can drain the battery down before needing to recharge the battery without harming its life.  Certain solar batteries may be depleted further 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 compared to a battery with less.

Capacity 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 both a high capacity and higher power can run a large system for many hours; a battery with low capacity and higher power can run 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 energy.  Batteries require power to control and efficacy compares the energy taken to charge a battery together with the amount of energy that the charged battery produces. 

Manufacturer

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