(Although the instructions on this page (as of May 2008) include details for Linux and refer to a CD image, it is actually provided as a Windows executable. For newer ThinkPads there is an official bootable CD image. For those who do not have a floppy, David Smith prepared a bootable CD image (dead link, a copy is also available here) from the T22 floppy images. Make sure you get the specific version of program made for your ThinkPad model. The program is downloadable from IBMs support site as three floppy disk images.

A way to get these batteries back to full capacity is to run the 'Battery Rundown' function of IBMs 'PC Doctor for DOS'. Some people experience sudden drops in their batteries capacity. Read more about this on the associated problem page. ThinkPad 600 power management causes batteries to die before they should. If storing inside a refrigerator, beware of humidity, and be careful with cold spots that can easily freeze the battery if anything goes wrong. If you have spare Li-ion battery packs, store them at 40% charge in a cool place (15C being a recommended temperature, do not let the batteries freeze).

Under Linux, this is supported on recent models by the tp_smapi driver (and even without tp_smapi, if you have a dual-boot setup, you can set the thresholds under Windows and they will be remembered as long as you don't power off your machine with AC disconnected suspend to RAM is OK). On recent ThinkPads, charging thresholds can be configured in the bundled software. When possible, remove Li-ion batteries while operating from AC as the notebook gets hot enough inside for that to damage the battery in the long run, even if charging is stopped. If you use your laptop at a desk, reduce battery wear by maintaining an appropriate charge level.

cool and dry, but do not freeze them: 10-15C is recommendedД«atteries, especially of the modern Li-Ion type, wear out quicker when they hold a large charge or are subject to higher temperatures (see above).

never fully charged or discharged, ideally at about 40%.

fully discharge, then fully charge battery when needed to recalibrate fuel gauge newer battery pack models require this less often, old ones might need it as often as every 30 cycles.

keep notebook off while charging due to heat.

avoid charging if battery is nearly full, unless you will need its full capacity soon keep it on the 30%-85% charged range.

remove battery when on AC (due to heat).

avoid deep discharges except when resetting fuel gauge or reconditioning a battery partial dis-/recharges are better for the battery lifetime (note: fuel gauge will slowly get inaccurate over time).

avoid exposing the battery (or notebook) to excessive heat.

always do complete discharge/charge cycles.

For older models check the HMM (Hardware Maintenance Manual) for your ThinkPad.Д«attery treatment Battery life expanding guide

Lenovo has a website dedicated to servicing ThinkPads, but it only covers the more recent models. Look at your models category page for IBMs official maintenance guide for that model. Here you can find general hints about keeping your ThinkPad in good shape.
