How Do I Fix My Laptop Battery Not Charging

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 make certain you get the most bang for your 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 two parts:

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

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

By the conclusion of the article you will know exactly how to pick out the best battery to 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 sort of battery that will fit your system.

They’re also among the longest-used and most dependable 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 whether you are just making the move to a solar panel system, lead acid batteries might be a very good option.  They’re the type of battery we use in most of the battery banks within our solar panel systems.

Saltwater Batteries

Saltwater batteries are more expensive than lead acid batteries, but also have a greater lifespan.  Unlike lead acid batteries, saltwater batteries are essentially brand new to the industry and remain 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 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 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 ion battery may be the highest rated, but also the most expensive.  An example of a lithium battery is the Tesla Powerwall.

Part 2) Assess the components of batteries.  Once 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 research to find the ideal 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 many systems, a battery will cycle daily, meaning it is going to drain and charge regularly.  With each cycle, the battery’s ability to maintain the same charge lessens slightly.  So one component to consider is the warranty on the battery which 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 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 before needing to recharge the battery without harming its life.  Particular solar batteries can be depleted farther 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 many hours; a battery with low capacity and high power can operate 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 store energy.  Batteries require power to control and efficiency compares the energy taken to charge a battery with the amount of energy which the charged battery generates. 

Manufacturer

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