How To Fix S10 Battery Drain

Or have you wondered what makes one deep cycle battery greater than another?  If so, this article 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 your buck)!

When picking a battery (or batteries) to your solar panel system, there are three 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 components of batteries, such as: depth of discharge, capacity and power, efficiency, battery life, and manufacturer.

By the end of this article you will know exactly how to pick the ideal battery to your own solar panel system!

So let’s begin…

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. 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 reliable batteries in existence.  When compared with 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 transfer to a solar panel system, lead acid batteries may be an excellent option.  They’re the type of battery we use in the majority of the battery banks in our solar panel systems.

Saltwater batteries are more expensive than lead acid batteries, but also have a better lifespan.  Contrary to lead acid batteries, saltwater batteries are basically brand new to the industry and stay both somewhat untested and harder to come across.  Of the three kinds 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 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 choices, 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.  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 research to find the perfect battery to your system.  

Cost

Price 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.  Sometimes though, certain batteries could be overkill for your system so the most expensive battery may not be the best choice always.

Battery Life and Warranty

For many systems, a battery will cycle every day, meaning it is going to charge and drain regularly.  With each cycle, the battery’s ability to maintain the same charge lessens slightly.  So 1 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 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 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 save.   Power is how much energy that a battery can provide at a certain moment.  A battery with a high capacity and high 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 store said energy.  Batteries require power to control and efficacy compares the energy taken to charge a battery with the amount of energy which the charged battery produces. 

Manufacturer

This might not be a component most would consider, but it is something to focus on.  As with other technologies, there are both trusted brands and start-up brands.  A trusted brand comes with known flaws and advantages; a startup brand can perhaps have better technology, but could also have unknown technological difficulties.  Based upon your system needs, you might decide to go with a well-reviewed firm or one that is brand new to the market.
