Will Your Laptop Battery Last As Long As They Say?

        Will Your Laptop Battery Last As Long As They Say?

       If you have a laptop, you’ve probably noticed that your laptop battery doesn’t seem to last as long as the manufacturer says it will. Maybe you just figured you were a power user, or maybe you thought it was just your imagination. It isn’t.

       A company called “Which?” that runs a popular website offering expert advice on numerous topics, including technology, recently completed a year-long survey into laptops made by a variety of manufacturers. Their findings support what users have been saying all along.

       With one notable exception, laptop manufacturers overstate the expected battery life of their equipment, sometimes by as much as 50 percent! Here are some of the key findings, broken out by manufacturer:

• Acer Equipment – According to the manufacturer, their laptop batteries should last an average of seven hours and 53 minutes. In independent tests, the actual laptop battery life was found to be five hours and 59 minutes.
• Asus Equipment – Manufacturer’s claim: 10 hours and 12 minutes. Independent test results: six hours and 53 minutes
• Dell Equipment – Manufacturer’s claim: nine hours and 15 minutes. Independent test results: five hours and 12 minutes.
• HP Equipment – Manufacturer’s claim: nine hours and 48 minutes. Independent test result: five hours and 2 minutes.
• Lenovo Equipment – Manufacturer’s claim: six hours and 41 minutes. Independent test result: four hours and 34 minutes.
• Toshiba Equipment – Manufacturer’s claim: seven hours and 58 minutes. Independent test result: four hours and 45 minutes

        The one bright spot in the report? Apple equipment actually lasted longer in independent tests than the company claimed (ten hour claim vs. ten hours, 15 minutes in independent testing).

      Unfortunately, this means that unless you’re using an Apple laptop, the manufacturer’s data on expected laptop battery life is essentially worthless and should not be factored into your decision-making process.

      Which? researchers reached out to the manufacturers of the equipment they tested for an explanation and were told that the company must have used a different testing paradigm to measure expected laptop battery life.

       That’s possible, but it doesn’t fare well in the real world, where users have been complaining for years about this very issue.

Can your laptop battery be overcharged?

         Can your laptop battery be overcharged

I see a lot of people asking if the laptop battery can overcharge.What happens if you overcharge?

 Most laptops today use lithium Ion (Li-ion) batteries. Overcharging Li-ion batteries is not a problem and does not affect the laptop battery life span. These  laptop batteries can be charged 300 to 500 times, and they have an internal circuit to stop the charging process at full charge.

The control system prevents overcharging, which can cause the lithium ion battery to overheat and potentially burn. This is why the Li-ion batteries are more expensive. The only way for the Li-ion battery to overcharge is if the charging system malfunctions, and then the battery will heat up while in the charger. If you don't plan to use your laptop for long period of time, you can extend the life of your lithium ion laptop battery by storing it with a 50 percent charge. A fully discharged battery left for a long period of time will lose its charging capacity. Fully charged batteries discharge when they are left unused, and will lose effectiveness. This is why it is recommended to discharge a Li-ion battery until it is almost out before shutting down. Running a Li-ion battery down completely will diminish capacity. Keep the laptop battery in a cool place and do not store your computer for a long period of time while it is fully charged.

Older laptops use Nickel-cadmium (Ni-Cd) and Nickel Metal Hydride (Ni-MH) batteries. They require more maintenance than Lithium Ion batteries. They must be fully discharged and then fully recharged so that they don't lose battery life. These laptop batteries can be overcharged only if they go through too many cycles of charging and discharging, which reduces their effectiveness and capacity. It is better to charge all batteries fully before use; then use on battery power until the optimum level for each battery type is reached, before recharging.

Prevemt your laptop battery from overcharging,and protect your laptop and battery.
