How To Fix Galaxy S9 Battery Drain

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 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’ll do this in two parts:

Part 1)   Instantly compare the three main 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 this article you will know exactly how to pick out the ideal battery for your solar panel system!

So let’s get started…

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 reliable batteries in existence.  Compared to the other batteries we will discuss in this report; they are the cheapest option but you trade price for some battery life and depth of discharge.  But for homeowners needing lots of storage for a lesser cost, or whether you are just making the move to a solar panel system, lead acid batteries may 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 greater lifespan.  Unlike 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 3 types of batteries, saltwater has the greatest depth of discharge, so you’ll find the most output per fee before needing to recharge.

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 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.  Once 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 research to find the perfect battery for your system.  

Cost

Price 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 may be overkill for your system so the most expensive battery may not be the ideal choice always.

For most systems, a battery will cycle every day, meaning it is going to 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 warranty on the battery which guarantees a specific 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 application, you can extend the life of your batteries.

Depth 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 may be depleted further 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.

Ability 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 given moment.  A battery with a high capacity and higher power can run a large system for many hours; a battery with low capacity and high 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 said energy.  Batteries require power to charge and efficacy compares the energy taken to control a battery together with the amount of energy that the charged battery generates. 

Manufacturer

This may not be a part most would consider, but it is something to pay attention to.  As with other technology, there are both trusted brands and startup brands.  A trusted brand comes with known defects and advantages; a startup brand can perhaps have better technology, but could also have yet unknown technological issues.  Based on your system needs, you might decide to go for a well-reviewed company or one that is brand new to the market.
