4 Tips tExtend Your Lithium Battery Life:
Battery Memory - When I first got my new cellphone, my friend recommended tfully drain the battery before recharging it. His reasoning was connected tthe idea of battery memory. Allowing the battery tfully discharge then recharging tmax, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point tmax battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half
Battery Calibration - There are some benefits tfully discharging your lithium battery periodically, for laptops this can be especially important. If you start tnotice your battery meter becoming more and more inaccurate, it may be time for some battery calibration. Allow your lithium battery completely drain, then charge until the battery is full again. This will calibrate your battery giving you more accurate readings
Consequences of Heat - Another enemy of lithium battery life is heat. If you were tleave your laptop plugged in and running for a year, you should expect the lithium battery capacity tbe anywhere between 60% t80% of it's original max capacity. This is why people that use their laptops as desktop replacements will notice greatly reduced battery life performance after one year of use. This issue can be resolved by removing the battery while using a corded power source
Battery Storage - If you don't plan on using your lithium battery for prolonged periods of time, then you'll want treduce the charge level t40% and place the battery in the fridge (not freezer). Storing the battery at 100% charge level applies unnecessary stress and can cause internal corrosion. On the other hand, if the charge is tolow, the battery can become permanently unusable, due tbattery self discharge
