Ipad 2 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 purchasing your new battery (to ensure you get the most bang for your buck)!

When picking a battery (or batteries) for your solar panel system, there are 3 categories of batteries that work best.    We will do this in two parts:

Part 1)   Instantly 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 manufacturer.

By the conclusion of the article you will know exactly how to pick out the ideal 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 depend 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 are the most commonly used rechargeable battery in the world. They’re 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 cost, or if 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 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.  Contrary to lead acid batteries, saltwater batteries are essentially brand new to the industry and stay both somewhat untested and more difficult to come across.  Of the three kinds of batteries, saltwater has the best 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 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 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 elements 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 buying batteries as well.  In some instances though, certain batteries may be overkill for your system so the most expensive battery might not be the best choice always.

Battery Life and Warranty

For most systems, a battery will cycle every day, meaning it will charge and drain regularly.  With every cycle, the battery’s ability to hold the same charge lessens slightly.  So one component to consider is the guarantee on the battery which guarantees a certain number of cycles of useful life.  But keep 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.

Depth of Discharge

Depth of discharge is how much you can drain the battery down before needing to recharge the battery without damaging its life.  Particular 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.

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 given 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 quantity of energy it took to save energy.  Batteries require power to charge and efficiency compares the energy taken to charge a battery together with the amount of energy which the charged battery produces. 

Manufacturer

This may not be a part 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 defects and benefits; a start-up brand can perhaps have better technology, but can also have yet unknown technological issues.  Depending upon your system demands, you may decide to go with a well-reviewed company or one that is brand new to the market.
