restoring a battery,
#1) Use High Quality Batteries
So this tip probably seems obvious, but the old adage ‘You get what you pay for’ holds true for most deep cycle batteries.
Cheap off-brand batteries from China are flooding the market right now and you want to avoid using these. They generally have a much shorter lifespan compared to quality batteries that you pay a little more for upfront.
High quality flat plate batteries can last between 10-12 years. The more expensive tubular plate batteries can even last as long as 20-25 years if maintained properly.
Paying for higher quality batteries upfront that last 10-25 years may seem expensive but it actually ends up being more expensive to buy cheap batteries …then replacing them every couple years (because they die early).
If you want to save money on your battery bank don’t buy “cheap” batteries, instead get quality used batteries and recondition them back to their original condition.
Don’t know what batteries to use? If you don’t know what kind of batteries to get for your off-grid energy system, read our article about the 3 best batteries for off-grid energy systems.
#2) Proactively Prevent Corrosion
Even if you use the most expensive, high-quality batteries in your battery bank, it won’t be of much use if the batteries aren’t cared for and corrosion or acid is on them.
Extend lifespan of lead-acid deep cycle batteriesBefore you assemble all of the components of your battery bank, make sure to individually coat the terminals, wire lugs, nuts and bolts with a non-hardening sealant.
You can also apply a thin coating of petroleum jelly to the battery terminals for some extra protection.
Lastly, seal exposed wire at a terminal lug using submersible rubber splice tape or something similar.
The reason all of this has to be done before assembly is because it ensures that all of the parts are equally protected. If you apply protective substances after you finish assembling the system, there is a good chance that dirt will get into small spaces that weren’t properly coated.
#3) Make Sure That the Battery Bank and PV Array are Correctly Sized
If you’re using a solar panel or wind power system, you should make sure that your battery bank is big enough to carry six to ten days of load.
This ensures:
1.You’ll always have a nice back-up supply of power.
2.And you’ll also be able to use your batteries a little more gently so you don’t have to consistently drain them.
#4) Fully Charge The Batteries Every Three Weeks
Lead Acid Battery MaintenanceAt the very least, make sure to fully charge your batteries every 3 weeks.
This reduces corrosion on the inside and ensures equalization.
#5) Keep Your Batteries at an Ideal Temperature
Because temperature extremes cause batteries to deteriorate much faster, it is important that you keep your batteries in a place where the temperature is relatively stable.
Aside from enclosed above-ground structures, you can also create a structure that is partially underground. This way the temperature in the structure will remain the same no matter what the weather is like outside.
#6) Don’t Install More Than Three Parallel Battery Strings
Ideally, your battery bank should only be made up of a single series of cells. The more cells that are included, the higher the chance of there being random defects. There’s also a greater chance of losing equalization, resulting in cells failing prematurely.
If you can’t stick to just a single series of cells in your battery bank, limit it to three parallel battery strings.
#7) Install a Renewable Energy System Digital Monitor
A renewable energy system monitor will help you keep track of the performance of your system (including the battery bank).
It will also help you troubleshoot any issue that comes up with your system so you can troubleshoot it before it turns into a bigger problem.
It will also help you maintain your batteries so you don’t have any surprise repairs that are costly and could have been avoided.
What else can you do to make your lead-acid deep cycle batteries last longer?
There are additional ways you can extend the life of your deep cycle lead-acid batteries. We cover all of these methods in the EZ Battery Reconditioning Program.

Solar energy isn’t for everyone. It’s for adventurers, for pioneers, for people who like to save money. It’s for people that prefer the view of the sunset without wires in the shot. It’s for people who want to leave the planet in better shape than they found it. It’s for people who care about their children and future generations.
For the first time in history, going solar means you can save money, make money, go green, and help to save the Earth!
It is said that the Earth receives 10,000 times more energy from the sun than we will ever use. That energy is transferred into weather movements, tides, and currents while heating the oceans. Heat from the sun causes water to evaporate into clouds that produce rain. With that rain and through photosynthesis, all plant life harvests the energy of the sun to grow.
For the past 100 or so years, humankind has has been figuring out more and more ways to use electricity, and therefore, also to consume more of it. Water wells became water pumps, manual drills became electric drills, candle light became electric light, hand-washed clothes are now cleaned by a washing machine. Wood stoves have been replaced by forced-air heaters, and sitting on the porch in the breeze has been replaced by air conditioners. Only since the onset of social media has the mainstream public gotten serious about reducing energy usage and real conservation.
The viral idea that Living off-the -Grid is something new is one of the strangest conundrums I’ve ever heard of since mankind has been living off-the-grid for thousands of years. So when a friend and I started this little Facebook page, we had no idea how well the world would love reading about others and how they manage to be off the grid!
We all do it in so many amazing ways! Some live in cars, some in tents, some in the wilderness undetected. Some folks do life like camping in an RV, and some really live in Alaska 40 miles from the gas station, and still manage to survive.
If today I were to announce a new technology for the first time that will harvest the suns energy just like plants do, and do it better, chances are you would line up out the door to get one! But today we use so much electricity, that we must cover a large part of a roof with panels to make enough energy to feed all those machines! Panels are big and require mounting in a way that faces the sun as directly as possible. Most deliveries come in a semi-truck, and need to be raised up onto the roof of the house. Long racking systems need to be installed, and the roof must be leak-protected. That’s why you can’t just go to the hardware store and buy them. They are big, and because electricity is involved, permits and electricians are required to get the job done in most locations.
So now that we understand that it’s complicated to get solar panels on a roof, and complicated typically equals expensive, how can we make this work for you?
Through the Solar Buyers Club, we have enabled group buying power to lower the cost of supplies, and eliminated the costly sales position from the equation, bringing unheard of pricing to the industry. With zero-down financing, you can give up your electric bill and make a small payment on a solar system! Something magical happens the moment you put a solar panel system on your housetop. Everybody you know will ask you what it cost and where you got it!
We have put a referral mechanism in place that will allow you to make a substantial referral fee every time someone buys a system because of you! In fact, it won’t take long for most customers to pay off their system by simple referrals, thereby helping everyone around you to save money, make money, go green, and help to save the earth.
