All the Dells we had at work, when they were shelved with the batteries in, and then pulled out several months later, then batt had to be replaced. I'd say no. And don't long term store with battery in. |

I'm sure some of the experts will chime in here, but, my understanding is that the Dell batteries are the lithium polymer ones. These will be harmed discharging them all the way. The older NiMH's were not harmed by doing this, but the newer ones will be.

Leave at 50 to 60% charge for best live , they have no memory. If you ever get a bad one shoot it like thermite and tanerite mixed.

The "drain all the way" philosophy comes from the days of NiCd batteries, which are prone to the memory effect. NiMH and Li-polymer batteries are supposed to be free of this effect, but it still can happen. So, if you can afford it (meaning you won't be going anywhere and can leave it plugged in for a long time, go ahead and deep cycle the batteries. It's not necessary every cycle, though.

It is entirely dependent on the chemistry of the battery. My Sony uses Lithium Ion which does not develop "memory" and therefore does not need to be "cycled".
Read the manual....... |

Completly draining LiPolys WILL DAMAGE them.
the old drain all the way comes from NiCd and NiMH batteries |

check to see what type of battery it is. if its lithium ion, Its not suppost to matter. I still drain them to 10% or so when i use them. You bought a laptop for mobility SO USE IT. I don't understand people that buy a laptop and then leave it plugged in 24X7. Might as well use that battery while its still working ya know. Them laptop batteries are not cheap. |

Interesting...the techie wizards here at work obviously need a refresher course. Thanks for the info. |
