Hi

It seems all of a sudden that the laptops we purchased just over 12 months ago are having battery failures. Not surpising given that they only have a 12 month warranty. However its causing us a few problems internaly.

One problem we have is we purchase all the laptops in bulk and then issue them throughout the year. This means that some of the laptops are in the store for a few months before being deployed. So are wasting a few months of warranty.

Does anyone have any tips on the best way to prolong battery life. Also would we be better storring the laptop charged or flat?

if they are going to be in storage any length of time.

But laptop batteries last about 2 years, whether used or not. Of course, anything involved here stores better in a cool, dry place.

Users should be unpluggging there laptop i would say atleast a couple times a month and allowing the laptop to die then allow it to fully charge. Otherwise with in a year or so if you unplug the laptop from the wall it will die within a few minutes.

NiCd batteries and other nickel metal-hydride batteries do need to be exercised to eliminate memory effects.

Lithium ion (Li-OH) batteries should NOT be exercised. These batteries should not be discharged past the laptop cutoff point, and then only to recalibrate an internal "fuel gauge" if it has one.
