Hi, looking to buy the 8 cell battery, must hold 95%+ of original capacity.

Will pay first.

Need it bought today or going to eBay

Still looking

Bump. Also have a 4-cell genuine that holds full charge with about 20 cycles to trade

I bought this one one ebay for $30



The seller with 100% pos feedback said it came with a new computer and was unused. I mistakenly assumed it would fit a tablet, so I have no use of it. Naturally since I don't have the proper computer to test it in, I haven't been able to confirm it's genuine, or has a 0 cycle count, but it does look new.

I have an x60 and x61 tablet, and several t61 models (both 14.1 and 15.4), and will consider a trade for anything of equal value that I can actually use.

That's not genuine.

Still looking

How much are you offering since its something so specific you need?

It's just a battery for a laptop. I wouldn't call it "something so specific" that would command some kind of price that needs to be haggled.

Bump

I think he probably just meant that a 95% or more of original capacity genuine x60 battery is a little *hard* to find, as you can see by this thread. It's *easy* to find 8 cell used OEM batteries for these holding 50 % to 75% of their original charge. I was fortunate enough to find a few New, never used ones from a corporate surplus dealer I do business with a while back. I charged them up to check them and they held 100% of their original charge and sold out on the Forum very quickly.

Something interesting I've noticed about x60/s x61/s batteries, which I would like some knowledgeable comments on, is that the used OEM ones I encounter are generally well spent. They may not even have that many cycles on them, but the Full Charge capacity is like 50,60,70% as I mentioned. It's difficult to find many of them with 85,90,95% of their useable life left in them. I have had much better fortune finding OEM T60 batteries with sub 50 cycles and 95 % charge. I have found and sold many of those on the Forum. So my question is: Do you think the fact that the x60, and, to a lesser degree, the x61, being prone to overheating, or at least running hot and burning up the palm rest, causes greater stress/wear on the batteries than the larger/better vented T60 chassis does and therefore the x60/x61 batteries lose their useful charge capacity faster? And also many of them fail/completely die much faster than the T60 batteries do? I have found many, many completely dead x60/x61 batteries, probably twice as often as I encounter completely dead T60 batteries, having bought and sold loads of these.

Does a laptop, (such as the x60), which runs hot on a regular basis cause greater wear on its battery? Does a cooler laptop put less strain on a battery in general? It would seem to me the obvious answer is yes, which might explain the higher wear level and higher failure rate of x60 series batteries that I have personally experienced. Is heat the only issue or was there a manufacturing glitch on some of the x61 batteries, as discussed in the thread here: http://forum.thinkpads.com/viewtopic.php?f=5&t=77524

A very interesting Panasonic/Sanyo squabble here: http://forum.thinkpads.com/viewtopic.php?f=2&t=71027 After reading both of these threads my theory is that the constantly high temperature of the x61 caused the premature death/failure of some of the Sanyo batteries in question, but there may also have been a manufacturing defect. I don't think the Sanyo batteries take "heat stress" as well as those with the Panasonic cells. Sorry for my unscientific terms, but I'm not an IBM technician. However, I am a brilliant thinker and I try to solve mysteries and piece things together The real problem is that it seems Sanyo/Sony and now "LGC (LG Chemical)" manufactured most or all of the x60 batteries as this Lenovo support page seems to confirm: http://support.lenovo.com/en_US/downloa ... D=PD014071 I don't know about the manufacturers of the x61 batteries. Panasonic batteries are becoming harder and harder to find. I wish Lenovo would employ Panasonic exclusively to manufacture its Li-ion batteries and that Panasonic would not join up with Sanyo, as someone mentioned in one of the threads I quoted above. I do know that all the x60 batteries I have come across seem to be Sanyo or Sony. The Sanyo batteries can last a pretty long time also but you probably have to coddle(pamper) and baby them. Nothing outlasts the Panasonics. I have a T60 9-cell Panasonic battery showing "Good" condition with 664 cycles holding 81% charge (68.96 Wh FC capacity). Mind you, it was manufactured in 2009 (FRU P/N 42T4620). Can anyone beat that record? The Panasonics keep going and going like the Energizer bunny. I hope they don't change/compromise their (excellent) battery manufacturing process. BTW, is LG Chemical the same company that made my old LG Lotus cell phone? They make pretty good cell phones. How do their batteries compare to Panasonic or Sanyo?

One other theory as to the higher failure rate/ quicker decline of the x60/61 batteries: The x60 is meant to be a true ultraportable and many people use it as such. They take it on the road with them, whereas the T60 is more of a stay at home laptop, being bulkier and heavier. Therefore, the x60/61 battery gets deeply drained/ fully discharged more often than the average T60 battery, maybe even to the below 10%, 5% or even 3% critical battery level, which is not healthy for a battery AFAIK. I know it is healthy to fully discharge/cycle a battery once in a while as part of regular battery maintenance.

By the way, I know there has been much discussion on the Forum about ways of mitigating/dispersing the heat and helping the x60 laptop to run cooler. Some very creative and effective solutions have been suggested. However, I purchase most of my batteries from corporate surplus resellers so the x60/x61 batteries I obtain were used in x60 laptops which have come off lease and obviously the corporate users didn't know about/employ many of the elegant techniques you guys have come up with to help their x60 machines run a little cooler. What's really nice is when an asset recovery specialist in a company somewhere finds a large bin with boxes and boxes of New Old Stock x60 batteries and says, "Hey you guys, we forgot about these. They've just been collecting dust. We changed out all of our x60 equipment last year and don't need these anymore. Let's sell them off on Feebay." That's when you get your great deals! BTW, it seems a large batch of x61 machines are coming off lease and being sold by companies right now. So the price on these (x61 laptops) should go down dramatically as many of them flood the market. But I imagine this also means that large supplies of corresponding O.E.M. x61 batteries (which obviously also fit x60 machines, and were manufactured more recently than the crop of x60 generation batteries) may also flood the market soon, as company officials discover large boxes of batteries in their storage closets. That's how it seems to work.

I also wonder if Lenovo itself still manufactures O.E.M. x61 batteries, since the x61 is only about 4 years old.

Daniel,
the little YP in NYC.

New batteries are still around from what I've seen but I haven't seen a 2011 mfg date as I havent bought or encountered a recently purchased X61 battery, so that is a good question whether or not production of these batteries has stopped or not.

I use an X61s basically every single day and on the battery quite often. The heat of the palm wrest on my machine is minimal, but even at it's hottest the battery itself does not really get any heat even though it is closest to the processor.

I guess its possible that the reason you find many diminished X6X batteries is that the batteries on these machines actually get used as opposed to the T6X machines that sit at a desk and will appear to be quite healthy for a while then probably drop rapidly because sitting in their fully charged state at a desk is not conducive to battery health.

That's my guess.

Thinkpad lover was right in his assumption about what I meant by "something so specific" you are basically asking for a new battery.

I have an X6x 8 cell battery in great shape. First used date 03/11 with 44 cycles and a full charge capacity of 70.75wh and a design capacity of 74.88wh and I am a battery freak and have never let this bottom out except once to condition it, and whenever I plug in for any extended period of time the battery is removed.

I can sell it for 70 dollars shipped total if you can't find another good battery.

Not at that price, no thanks.

I will leave this thread and keep searching for eBay from time to time although that is such a PITA because all the batteries on eBay fall in three categories:

95% of lists are non-genuine
4% are used from companies with a lot of feedback (meaning they do their business on eBay, not a personal seller) and don't list the charge capacity, and if asked they say they can't/won't test them. I ordered one such battery and it only held 52%. Luckily the seller refunded the money without issue.
1% are from personal sellers with more than likely good batteries and those are incredibly hard to find seeing as there's like 40 pages of x61 non-genuine 8 cell batteries to go through. And usually they aren't even listed (but can see in completed listings. Meaning the auction expired some time ago)

To make matters worse, if a personal seller, say bricked his X61, he might list his battery by part number (there's so many different ones that are compatible it's pointless to search by part number) only. Or "X61 battery". While I have X61s, X61 battery is compatible. So is X60s, and X60... it makes searching eBay for a genuine X6x battery a pointless endeavor.

Anyway I'll take off. If anyone stumbled on this thread looking to sell their battery I am probably still interested so send me a PM but I'm done wasting my time bumping this thread

Lenovo for sure still manufactures X6x batteries. In fact they are almost surely still manufacture T4x batteries (Small quantities, probably Sanyo only). I bought a new T4x 9cell in October 2010 that was manufactured in April 2010.

I don't think it's related at all. The X6x does not heat up more than the T6x. The reason the palmrest gets hot because it's thin and the wifi adapter is right under it. The battery is nowhere near the palmrest (it's in the back).

I really think it only has to do with the fact that there are many Panasonic batteries for T6x (all the best ones in your battery thread are Panasonic), while there were no Panasonic batteries for X6x - only Sanyo (which lose capacity fast after a certain age, usually ~2 years, and those genuine X6x batteries are far older), and Sony (which seem to be prone more than others to the sudden death syndrome).

I don't think that you will find a genuine 8-cell battery for less than 70$.

$55 for basically brand new. Still more than what I want to pay and from what I've seen on eBay in the past.

As a matter of fact Lenovo Outlet as these batteries for $74 shipped and I've heard that they're in like new condition from other users. So why would I pay $70 to someone from a forum member when Lenovo themselves offer a warranty and guarantee for the same price? But as you know, Lenovo and other such companies charge quadruple the actual market worth of the battery.

Similar conditions on eBay go for $20-45 shipped. I've seen at least 4 like that before but I didn't really want one then to spend. And as mentioned before I would just stick to eBay then, but it's such a hassle to search for the X6x batteries (see my rant above, lol)

As I said, not at that price, thanks.

It's up to you. I don't know about what kind of past you are talking about as 70$ for X6* 8-cell battery was a rather good price two or three ago as well. If even 55$ is more than you are ready to pay then I don't see how you are going to be ready to get any battery at all except if somebody just wants to give you it as a present. Good luck!

bugmn wrote:But as you know, Lenovo and other such companies charge quadruple the actual market worth of the battery.

Prices of the batteries at the outlet are nowhere near "quadruple" of the actual market worth, as is evident from the scant number of offers you received here.

You are not looking to pay market value. You are looking to cut a bargain deal. That's fine, but you have to be very patient and look very thoroughly.

ahh ata gam me israel? az ata yahol leavin lama ani rotzhe mehir tov stereptyp nahon

tzohek tzohek

I meant used/ebay/forum/craigslist market price, not retail market price. My mistake.

The reason I'm not getting offers is because not every x6x owner frequents this forum, let alone interested in the marketplace section. Not only that, before today I didn't even specify my price range, so I don't think you can say that I didn't get any offers because my price is too low. So far I've only gotten one offer (not counting the non-genuine battery) for $70, what Lenovo charges. With such a small selection (specific model, specific part, specific forum, specific section) of course I won't be flooded with offers and I wasn't expecting to. But that doesn't mean I'm going to pay a lot of money for a part I have so little need to. I'm a frugal shopper and I like saving money. Right now I have no urgency for this battery, otherwise I would have bought it straight from Lenovo, wouldn't I? So yes, I guess you could say I'm looking for a bargain price, but that is the purpose of most forum FS/FT section, isn't it? Nobody comes to forums to pay current retail prices.

Topic got quite derailed, haha.

salamat

For example to show I'm not just taking these numbers out of thin air. Just in the past several days on eBay (too late now, doh!):

"very few cycles": $25 shipped http://www.ebay.com/itm/GENUINE-IBM-Len ... 336d662934

Boxed (listed as used though?): $42 shipped. http://www.ebay.com/itm/Genuine-40Y7003 ... 589030939e

I've seen several more since I started looking some weeks ago

sold to someone for $45 shipped. So I don't know where you're getting "you won't get a better deal than $70" from.. seriously

The various discussion on why X6x batteries fail, what price markup Lenovo generally sells batteries for, how difficult it is to peruse eBay for a bargain-priced battery, what batteries have recently sold for on eBay, and especially, how overpriced the buyer believes his Marketplace offers have been, may make this post more suited for GENERAL Thinkpad News/Comments & Questions.

If this is really an "item-wanted" listing for the Marketplace, it should have a price range the buyer is willing to pay, and as per Rule 9 of the Marketplace Guidelines, "price negotiation should be done through direct communication (PM or email etc) between buyer and seller, not in posted messages." -- just my opinion

bugmn,
Maybe you should stop beating around the bush, let people know how much you are willing to pay for this item, and wait for offers.

Otherwise, I agree with emtee3511 that this thread should not be in the marketplace.
