Batteries have come a long way through history. With the advent of the first Fujitsu laptop batteries, which consisted of paper and salt water coupled with metals, these marvels of harvested energy have evolved in capacity in the thousand-folds. Through science, we have innovated and experimented with the Fujitsu laptop batteries, using different metals, alloys, and materials until we found what type of metal held a charge for the correct task at hand. Today's most popular batteries are named the lead acid, alkaline, and lithium-ion. There are many more types, but we will only discuss the preceding in this article. Lead acid batteries are mostly used in heavy duty applications, such as car batteries. They have amazing longevity and can recharge themselves if allowed dormancy. Due to their toxic liquid nature, however, they are impractical in small consumer applications that we carry in our pockets every day. Alkaline batteries have dominated the market for decades, due to their reliability, stability, and charge life. They are much safer than lead acid batteries, and are very well suited for small electronics. Last, but not least, is the lithium-ion Fujitsu laptop batteries. The lithium-ion Fujitsu laptop batteries is modern civilization's marvel in technology. It combines the best qualities of both the old technologies and improves on it. It has excellent charge life, ability to recharge, and is extremely durable. About 99% of all portable electronics are powered by the lithium-ion battery, and as such, we will be talking about conserving the OVERALL life of the lithium-ion battery. Please take note on why I said overall; how you use your battery for the FIRST time will determine how much it likes you for the rest of your quality time together. So be nice! It's powering your expensive piece of equipment~
