I have a Toshiba sate lite m100 and I'm always using my laptop with AC power. and never take it out from power for using with battery. so I just want to know that for not destroying my battery is it better to take the battery out or its better to keep it inside.because some of my friends telling me that laptop battery has got expiry date it would be finished in a specific time and it needs to be charge an discharge at least once in a month.so its better to keep the battery inside .
And some other telling me that because you are not using the battery and always using the AC power so you need to take it out because battery has got charge limitation and in this case you are always charging it and destroying it.
Your computer knows when it it fully charged, so you don't need to take it out.However, you need to you the battery oce a month or so to keep the battery good.If you don't use it enough, it will gradually lose its ability to hold a charge.This happened to me. The laptop could only run on battery for 5 min when fully charged because it hadn't been used in several months.
This is a very difficult question to address, as it depends either way. You can do either or, but if you always use laptop AC adapter then it doesn't really matter. So long as you charged it from when it was dead then there should be no problems. Most laptop batteries have a weird charge function where they somehow mess up charge estimates when you haven't drained your battery, so if that's the case you're battery life will be shorter, but it doesn't make it unusable. Additionally, if the battery is full, then the AC should bypass the battery charge completely. So, if you're using AC all the time it shouldn't really matter, depending on how much you want to use it later away from the AC may make a difference, but not significantly.
You need to charge and discharge your batteries atleast once a month , it keeps circulation up.For proper maintenance , it’s important to keep the electrons in it moving occasionally.If you want to buy some replacement batteries for your used,you can go to www.battery-replacement.org look for it.
