dell laptop battery

Following facts: my netbook (Asus Eee PC 1005) had three months ago to a little problem with the power supply hot … now it broke three days ago, broke the Dell Vostro 1520 battery … I’ve ordered a new one and then but have now times a question

I just do not now what to Google to find my question fits here, I alternate a look:

I also have the old battery charged and discharged repeatedly that I use it mobile in the home (ie kitchen or bedroom balcony or times as required) and to stop charging the Dell Studio 1735 battery when it is empty … or at even one percent He will never stop completely empty because I’m also afraid that he does not durchschmorrt So now the PC So now my question is it better I pull the Dell Inspiron 1501 battery out completely and let it run übern current or it is not bad since I let the Dell Vostro 1510 battery charge is not always at 100% … I know he will not live as long but one Six months is already fierce (as old was the old who is now in the garbage bag is), I will my yes, then more power when it runs constantly can over power as if I have ten hours, the power supply completely disconnecting and then the HP Pavilion dv6000 Battery will be empty … what’s better?
