Batteries come in a variety of sizes from huge ones that can store enough energy to power entire cities to tiny batteries that are used to power hand-held torches. From the simple lead-acid cells in the mid-1800s, now technology has given way to rechargeable batteries that are cost-effective, environmentally-friendly, compact, and safer.
Based on the size and dimensions, batteries are divided into AAA, AA, C and D batteries. D rechargeable batteries are meant to be recharged over and over again.
