How do I read my laptop battery?
One of the easiest ways to determine what type of battery you have is to turn off the laptop and unplug it. Then remove the battery for a look. Most batteries have a variety of information printed on them, including the battery type, model number, part number, voltage, and charge current.
Types of laptop batteries:
Nickel Cadmium (NiCd) Batteries: These were the first rechargeable batteries made for laptops. They were relatively inexpensive, powerful, and versatile because they could be used in a wide variety of products. However, NiCd batteries have been abandoned by laptop manufacturers with the introduction of more efficient and lighter batteries.
Nickel-Metal Hydride (NiMH) Batteries: NiMH was a huge improvement in terms of performance, reliability, cost, safety, and capacity. The “memory effect” was the only problem with NiMH batteries, where they must be fully discharged before charging in order to achieve maximum performance. These batteries can still be found in older laptop models.
Lithium-Ion (LiON): This type of battery is the most popular for laptops because the “memory effect” has been eliminated and it is much lighter than the other two. However, the market price is also the highest.
A battery cycle is used every time a battery is charged or discharged. Technically, this is defined as the number of cycles a battery can perform before its nominal capacity drops below 80% of its original nominal capacity. Lifetimes of 500 to 1200 cycles are typical. For example, the NiCad battery has a cycle life of 500-1000 or more cycles.
Battery life depends on a number of factors. Most of the time, the design and performance requirements of the machine will determine actual battery life. For example, the use of the screen, hard drive, and other accessories have a significant impact on runtime.
What are smart and stupid laptop batteries:
Some laptop batteries are equipped with internal microprocessor circuitry that help manage battery energy, set the charger to use the correct charging algorithm, predict runtime, or provide a state of charge (SoC) display, according to the SBS (Smart Battery System) forum. These batteries are called “smart” batteries. These “dumb” batteries do not have these properties, can only be counterparts or only serve as a power supply.
- “Condition” is a term used to describe the full charge and discharge of a new laptop battery in order to maximize performance and achieve maximum rated capacity. NiMH and NiCd batteries must be conditioned at least once a month in order to reduce the “memory effect”.
- Metal connectors should be cleaned occasionally to maintain good conductivity
- Ensure that the device’s power management features are optimized in the BIOS and operating system by turning off the screen using the speed step
- Do not leave your laptop on overnight while it is charging. The laptop should be turned off occasionally.
- Store the battery in a cool, dry and clean place if you will not be using it for a month or more.
- Decrease the brightness of the LCD screen when you are watching a movie on our laptop. Decrypt DVD movies and save them to your hard drive to avoid constant use of the DVD drive which consumes a lot of power
- Never expose the battery of your laptop to heat, moisture, short circuits, drops or physical abuse.
