This 12V 40AH Lithium Ion Battery is the perfect replacement from a AGM, GEL or Lead Acid Battery. The SB40 is designed as a "drop in replacement" meaning all you have to do is take out your old battery and place the Lithium Battery in the same way.
Our Lithium Ion Batteries are Green, Non Hazardous and have about 30% more energy density in the same size case as a lead battery. Because your lead batteries can only be drained to 80% and are only recommended to drain down to 50% - In some cases the Smart Battery can produce over 50% more usable energy than the same size lead battery.
As you may know, Your existing lead based batteries are inefficient, obsolete and a problem waiting to happen. Typical Lead Acid Batteries have many problems including: they loose up to 30% of their energy per month from self discharging. They have a severe voltage drop when a load is placed on them, they can off-gas, leak acid and hazardous chemicals, do not last long, they are very heavy and made of a toxic material.
Our Lithium Ion Batteries are 99.9% efficient, Provide over 100% usable energy of the rated capacity, and have less than 1% per month self discharge.
Whether you are installing a new Solar System, replacing your Marine Boat Batteries or outfitting a commercial application, Our Lithium ion Batteries give you the chance to do energy storage right from day one. Most Important for you are the facts that Smart Batteries can last over 5000 cycles meaning you buy a Lithium battery once and you are done. And considering their longevity and the efficiently they are less costly than the heavy and toxic lead acid batteries.
If you want to "go green" the lithium Batteries are not only virtually indestructible but they are non-toxic. Our products are readily available direct through us or by contacting one of our local distributors closest to you. This fantastic technology is making our planet a better and cleaner environment.
