送信者: "Michael Kennedy" mike@com 件名 : Opened laptop battery to replace lithium ion cells (Lenovo X61 tablet PC) -- Where do I get replacement battery cells? 日時 : 2010年9月17日 13:40 "JoeSchmoe" wrote in message ... Have you ever opened up your laptop battery to replace the lithium ion cells inside (if so, I could use the help as I'm stuck). Here are the pictures of the operation on a Lenovo X61 tablet PC 8-cell 4500 amp-hour battery kidney-transplant operation. The outside of the IBM Lenovo X61 tablet PC battery pack has the part numbers: - FRU 42T4507 - ASM 42T5209 And the batteries themselves, seem to have numbers on them of: - cylinders BCM 3A6 72653 - rectangles C 3 171353 Any idea where to obtain these lithium ion replacement batteries? I think these are the batteries you are looking for. Measure your bateries and compare them to the specs for 18650 Li-ion batteries. I suggest googleing for a 18650 Panasonic with tabs. http://www.onlybatteries.com/cat_featured_items.asp?cat1=27&cat=2&id=163&uid=11 07 I have no expirence with this site. Just the first hit on Google. Some come with tabs welded to them so you can solder them togeather eaisly and avoid destroying the battery via heat. If they are the right size and right chemestry (Li-ion vs. NIMH) they should work. The mAh rating will probably be higher on new batteries than the originals becuase of advancements in battery technology. Just be careful and dont get these things too hot while soldering. They have been known to burst into flames like a flare. But thats why I suggest the tabbed verison. Mike |
