The only &quot;special&quot; treatment this battery gets is that it travels in my laptop (as opposed to being the extra battery in my backpack) when traveling through TSA security checkpoints.

My last full capacity ACPI reading is now&nbsp; 21060 mWh, and provides 1-2 hours of working time on my IBM X31 Thinkpad. In a few more months it will be time to replace the Li-Ion cells again. Luckly, a friend gave me an IBM T60 extended battery (containing 8 cells) that had failed. When I took it appart, it appeared that 6 of the cells worked fine, and two of the cells were dead (killing the entire battery). TaDa! 6 free replacement cells!&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I refilled the Li-ion cells in my laptop battery about 18 months ago.The battery has worked as expected since then.
