Comparison Of Lead Acid & Lithium ion Batteries
png

With the aim to overcome limitations of VRLA and Lead Acid batteries, researchers at Future Hi-Tech batteries ltd. have worked hard to invent better energy storage solutions in the field of batteries which is the need of current age. On comparing Lead Acid vs Lithium ion batteries, Lithium-ion batteries are observed to bear inherited characteristics of 100% efficiency, are lightweight, bear high energy density, customizable, etc. thus, they have emerged as modern-day technology.

Moreover, with a better load matching feature, it is most suited with renewable energy sources, thus Lithium is preferred over other conventional batteries. Here are some more comparisons of Lead Acid vs Lithium ion batteries.

Following are some of comparison to understand the difference:
