![]() Li-ion technology is much cleaner and safer for the environment. Environmental Impact:The lead content, as well as the electrolytes in lead-acid batteries, can damage the environment.On the other hand, Li-ion is one of the most expensive. Cost:Lead-acid batteries are one of the cheapest batteries available on the market, both in its initial cost as well as cost per kWh.Voltage Stability:Li-ion batteries are almost 100% stable in term of voltage, while in deep-cycle lead acid batteries, the voltage will constantly drop over its discharge (sloping voltage.).Lead acid batteries have an average cycle of 400-1,500. Cycle Lifetime:The best of Li-ion batteries can last 5,000 cycles, with the average being 2,000-4,000 cycles.On the other hand, Deep-cycle lead acid batteries typically have less than 80% charge-discharge efficiency, and can range from 50% to 95%. Discharge:Lithium-ion battery reached almost 100% charge and discharge, with even the worst, have 80% of efficiency.Weight:Lithium-ion batteries typically weigh 30% lighter than lead-acid batteries.There are more differences than similarities between the two battery technologies, and here are the most notable ones: Let's start with an overview of their differences. This article will attempt to cover the differences between the two, and you'll be the judge which one is the better bet. Both have their own advantages, as well as disadvantages. With the big companies moving towards lithium-Ion, does it have a surefire advantage over the Lead-cycle? Well, yes and no. Quite possibly the ones we have from big players like Samsung, Panasonic, LG, and Schneider Electric will also use lithium-Ion. The difference is, solar battery banks popular in the renewable energy community is typically made with deep cycle lead acid technology, while the Tesla Powerwall uses lithium-Ion Technology. While Tesla recently brought batteries to mainstream popularity with their announcement of the Powerwall back in 2015, actually, home batteries have been around for a while and have been one of the most important equipment for renewable energy enthusiasts and practitioners. On our previous articles, we have covered the usage of batteries to power our houses, how it might be the future of household electricity, and how it may benefit us in the long run.
