Lead Acid Batteries

Lead-acid batteries are essentially the most generally used rechargeable battery in the world. They’re also among the longest-used and most reliable batteries in existence. In comparison with the other batteries we’ll discuss in this report; they’re the most affordable option however you trade cost for some battery life and depth of discharge. But for owners needing a lot of storage for a decrease price, or in case you are simply making the move to a photo voltaic panel system, lead-acid batteries could also be an excellent possibility. They’re the kind of battery we use in a lot of the battery banks in our solar panel methods.

Another great thing about lead-acid batteries is that you should use the upkeep and reconditioning strategies we teach you within the EZ Battery Reconditioning program to greatly lengthen lead-acid battery’s lifespan

Saltwater Batteries

Saltwater batteries are more expensive than lead-acid batteries, but additionally have a greater lifespan. In contrast to lead-acid batteries, saltwater batteries are essentially brand new to the market and stay each somewhat untested and tougher to come back across. Of the three varieties of batteries, saltwater has the best depth of discharge, so you will get the most output per charge before needing to recharge.

Lithium Batteries

Lithium batteries are the costliest and longest-lasting of the three kinds of solar batteries. Their depth of discharge is lower than that of a saltwater battery, however greater than that of a lead-acid battery. Evaluating all three choices, the lithium battery is probably the best-rated, but in addition the costliest. An example of a lithium battery is the Tesla Powerwall.

Half 2) Examine the elements of batteries As soon as you’ve got picked one of the best battery kind for your solar panel or off-grid system (that meets your system’s needs), there are parts to discover to seek out the perfect battery on your system.


Value might be one of the more apparent elements. But the outdated saying, you get what you pay for” holds true when shopping for batteries as properly. In some cases though, sure batteries may be overkill for your system so the costliest battery is probably not the only option all the time.

Battery Life and Guarantee

For many programs, a battery will cycle daily, which means it is going to cost and drain frequently. With each cycle, the battery’s ability to hold the same charge lessens barely. So one element to contemplate is the guarantee on the battery that guarantees a sure number of cycles of useful life. However remember the fact that when you use the upkeep and reconditioning methods we train you in the EZ Battery Reconditioning program, you’ll be able to extend the lifetime of your batteries

Depth of Discharge

The depth of discharge is how a lot you may drain the battery down before needing to recharge the battery without harming its life. Certain solar batteries can be depleted additional than others, allowing for extra use between charging. Primarily, a battery with a ninety% depth of discharge per cycle will present extra battery energy per cost than a battery with less.

Capacity and Energy

Measured in kilowatt-hours (kWh), capability is the quantity of vitality a battery can retailer over time. The extra capacity a battery has, the extra energy it will possibly store.

Power is how a lot power a battery can present at a given moment. A battery with each a excessive capacity and excessive energy can run a big system for a number of hours; a battery with low capacity and high energy can run a large system however just for a short time.


Effectivity is the quantity of power used in comparison with the amount of energy it took to retailer said vitality. Batteries require energy to charge and effectivity compares the power taken to charge a battery with the quantity of energy that the charged battery produces. The higher the effectivity, the more cost-effective the battery.


This is probably not a element most would think about, but it’s one thing to pay attention to. As with other know-how, there are each trusted manufacturers and start-up manufacturers. A trusted brand comes with recognized flaws and advantages; a start-up brand can perhaps have higher expertise, but can also have yet unknown technological issues. Relying in your system needs, chances are you’ll determine to go with a effectively-reviewed firm or one that is model new to the market.
