Nougat Battery Drain Fix

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 buying 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’ll do this in two parts:

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

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

By the conclusion 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. 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

Lead acid batteries are the most commonly used rechargeable battery in the world. They’re also one of the longest-used and most reliable batteries in existence.  Compared to 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 lots of storage for a lesser 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 are more expensive than lead acid batteries, but also have a greater lifespan.  Contrary to lead acid batteries, saltwater batteries are essentially brand new to the market and remain both somewhat untested and more difficult to come across.  Of the 3 kinds of batteries, saltwater has the greatest 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 kinds of solar batteries.  Comparing all three options, the lithium ion 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 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 elements 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 buying batteries as well.  In some instances though, certain batteries could be overkill for your system so the most expensive battery may not be the ideal choice always.

For most systems, a battery will cycle daily, meaning it will drain and charge regularly.  With every cycle, the battery’s ability to maintain the identical charge lessens slightly.  So one component to consider is the warranty on the battery that guarantees a specific number of cycles of useful life.  But keep in mind that when 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 damaging its life.  Particular solar batteries can 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

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 store.   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 massive system for several 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 store said 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 produces.  The higher the efficiency, the more cost-effective the battery.

Manufacturer

This may not be a part most would consider, but it is 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 start-up brand can perhaps have better technology, but can also have unknown technological issues.  Based on your system needs, you may decide to go with a well-reviewed firm or one that is brand new to the market.
