There are many ways to extend the battery life of your laptop, and here I have the following suggestions.First of all, if your laptop is really used as a compact desktop at home or at work, there is actually not much travel, removing the battery will make you lose its function as a "UPS.The solution is to buy a real UPS.For a laptop, you only need a small one (300 to 350VA) that can be found for $40 or less (sometimes even "free after rebate "), UPS is much cheaper than using a $200 lithium battery as a UPS, but in the process it will be destroyed in 6 to 24 months.The next thing is that despite the general advice of removing laptop batteries that are not needed and not used, the battery needs to be used 2 to 4 times a year.So occasionally put it back in your laptop, pull it down to about 25%, then charge it to about 60% (or 100%, and then charge it to 60% );Lithium batteries are stored better in case of insufficient charging, although in my personal experience I did not find this difference very important ).Finally, it may not be a good idea to remove the battery when you stay at the hotel for a few days, even if you don't need it.There is a high risk of forgetting the battery in the hotel room when checking out, you can put the battery in your laptop bag to mitigate this risk, but ask anyone using a PC Card "lost dongle Cable ".Please also note that the life of the lithium battery is limited in terms of the number of charge/discharge cycles.Although this varies depending on the battery model, it is in low powerto-Hundreds of them (such as typical 300 to 600 cycles ).If you really use the battery while traveling, charging and discharging every day, the fact will "let you" no matter what you do ".But, more often, people find that they have damaged the battery without actually using it, leaving the battery on the laptop when it is plugged in continuously.We have solved the problem.The last comment is that, given the price of the laptop battery, it is worth noting that some extended warranty covers the battery.If you are really going to use the battery in large quantities (see previous paragraph), this may be worth considering when Buy More's color shirt man offers you an extended warranty when purchasing a laptop.Find out if the battery is covered, and if your usage mode is like this, you may experience more time than the initial battery during the extended warranty period, maybe you're in one of those situations where it really makes sense to extend the warranty
