  T ypes of Laptop Batteries-Nickel Cadmium   ( NiCd )   Batteries: These were the first  rechargeable batteries manufactured for laptops. They were relatively  inexpensive,  had high output and versatile, because they could be used in a wide variety of products.  However,  NiCd batteries have now been abandoned by laptop manufacturers with the introduction of more efficient and lighter-weight batteries.   Nickel Metal Hydride (NiMH) Batteries- NiMH was a big improvement concerning power output, reliability, cost, safety and capacity. The “memory effect” was the only issue with NiMH batteries which require them to be fully discharged before recharging to gain maximum output. These batteries can still be found in older model laptops. Lithium Ion (LiON) :- This type of batteries has become the most popular for laptops since the memory effect has been eliminated, and much lighter than the other two in weight. However, the market price is also the highest. Battery Cycle: One battery cycle
