Which battery sits flush with 15" T60 / T60p case?

[xsixt]

Wondering whether it is the 4-cell or the 6-cell battery, that sits flush with the 15" (non-wide) T60p chassis?

I have the 9 cell currently, and that one protrudes quite a bit from the case.

I think both the 4 and 6 cell batts will fit flush.

There is no 4-cell for a T60, only 6-cell (flush) and 9-cell (protrude).

Legend! Thanks for clearing that up.

I read that the 4-cell sits flush with another model - perhaps the 14" Widescreen (T61)?

Yes. Early 14" widescreens had only flush 4-cells. This includes the Z60t/Z61t (Z6x 4-cell battery) and 14" wide T61/R61/T400/R400 (T/R 14W 4-cell battery).

Since the T410 series, the design changed and once again they have flush 6-cells.

Good trivia - thank you.

Surprisingly difficult to find this sort of info by web searching, it's like putting a FRU into ebay and seeing all the "Genuine" "Replacement" options.

Ain't that the truth.

And the two different style x61 batteries makes it even worse. I have all three styles of T61 (14" reg. 14" WS and 15" WS). The 14" WS is approx 1/2 in shorter front to back from the other two. They couldn't figure out how to use the same basic planar & case style for all 3???

Some of the smaller batteries are rare too - I thought I got lucky when I found a "brand new" genuine X61T 4-cell a couple of years ago. When it arrived after it's 30 day detour around the world using "NL Mail", it was indeed genuine and brand new with it's 0 charge count, but it was completely DOA

I ordered a supposedly genuine 6-cell T60 battery from ebay - hopefully it's real and works otherwise it's money back guarantee time

Yeah, especially the 4 cell slim battery for the X6xs is hard to find (there are no non-genuine batteries in this case). I'm using a thick 4 cell battery now in my X62s, which is not really beautiful.

I found one of the flat X61s batteries, though the capacity on it is pretty bad.

And it was never good to begin with!

A Core 2 Duo and a tiny battery, thats pretty much a desktop with an attached keyboard and screen.

A Core 2 Quad and a tiny battery, well that IS a desktop. Would you like to know the battery life of a W700 with a 7wh battery .

Very funny

I'd say, re-cell it, but today's cells in that form factor aren't really better than the old ones, whereas the round 18650 cells made a huge leap in capacity.

Is re-celling a doable option? I have a few T60 batteries, and the 18650 cells in them are in pretty bad shape, some of the batteries last for about 20 minutes. Also I think I read it somewhere, that when these batteries die completely, the battery circuit in them shuts down, and even if we replaced the cells, you wouldn't be able to charge it. I am still thinking about reading up on this matter, but there is not much information out (in english at least), and what there is, sometimes contradicts different sources.

Some non-genuine batteries don't lock up. But the real thing is this:
