Understanding Laptop Batteries
Laptop Battery Type:
Nickel Cadmium Battery (NiCd): This is the first rechargeable battery produced for laptops. They are relatively inexpensive, have high output and are versatile, because they can be used in a variety of products. However, NiCd batteries have now been abandoned by laptop manufacturers by introducing batteries that are more efficient and lighter.
Nickel Metal Hydride (NiMH) batteries: NiMH is a big improvement regarding power output, reliability, cost, safety, and capacity. “Memory effects” are the only problems with NiMH batteries that require the battery to run out before being charged for maximum results. This battery can still be found in older laptop models.
Lithium Ion (LiON): This type of battery has become the most popular for laptops because the memory effect has been removed, and is much lighter than the other two. However, market prices are also the highest.
One battery cycle is used each time the battery is charged or discharged. Technically, this is defined as the number of cycles a battery can take before its nominal capacity drops below 80% of its initial rated capacity. 500 to 1200 cycles are typical. For example, NiCad batteries have a life cycle of 500-1000 or more.
Battery duration depends on a number of factors. Most of the time, it is the design, and the power demand made by the machine determines the actual battery running time. For example, the use of screens, hard drives, and other accessories will significantly affect the run-time duration.
What is a Smart and Stupid Laptop Battery:
Some laptop batteries are equipped with internal microprocessor circuits that help manage battery energy, set the charger to the correct charging algorithm, predict operating times, or according to the Smart Battery System (SBS) forum, provide state-of-charge (SoC) indications. This battery is called a Smart battery. The batteries are referred to as, stupid not to have these features, maybe only partners, or can function only to provide power.
Optimizing Laptop Battery:
1. Condition is the term for full charging and use of a new laptop battery to maximize performance and enable it to reach maximum capacity. NiMH and NiCd batteries need to be conditioned at least once a month to reduce memory effects.
2. Metal connectors must be cleaned occasionally to maintain good conductivity
3. Make sure the device power management features in the BIOS and Operating System are optimized, turn off the screen, using speed steps
4. Avoid leaving your laptop all night while charging. The laptop must be turned off occasionally.
5. Store the battery in a cool, dry and clean place if you are not going to use it for a month or more.
6. Turn off the brightness of the LCD screen when watching movies on our laptop. Decrypt DVD movies and store them on your hard disk drive to avoid the constant use of DVD drives which consume a lot of power
7. Never expose your laptop battery to heat, humidity, short circuit, drop, or physical abuse.
