Battery supplier for X series

[jtt3011]

Supplier is in Germany or Switzerland, so this is probably of interest only to European residents. Url as follows:

The batteries are made by Panasonic, an outfit I hold in high regard, so I reckon they should be OK. Price is 37.90 Euros plus 9.90 Euros postage. Seems a reasonable price for a quality battery - though mine won't arrive for a day or three.

I also need a new battery for my X30, but the last time I bought a "replacement battery" from eBay, I was not very happy with it. The main problem was that last full capacity was not stored, thus the capacity approximation was totally wrong. Additionally the battery only had about 70% of capacity after 40 cycles. I would appreciate if you could post some additional information on the replacement battery you bought in eBay (e.g. battery information from windows battery tool or contents of /proc/acpi/battery/BAT0 with linux).

Thx,
Marcel

It hasn't arrived yet. It'll probably be delivered late this week, or early next.

I was persuaded to buy because I've used Panasonic batteries on other things, and been very satsfied with them.

If I have any views when I put it into service, I'll report back.

That battery is a bit interesting. If I'm not mistaken, the original X3x battery only had a capacity of 4400 mAh.

I'm interested in a North American source for 6-cell or 9-cell batteries, NIB or NOS, from reputable suppliers or manufacturers.

I think that was the norm for most, if not all, of the early X series.

[TheRedFox]

4400mAh is the X31 battery capacity. I bought an offbrand aftermarket battery off amazon. I don't remember specifically the vendor, but it gets the full 4.5 hours (not in linux, of course, but in Windows XP)

[uux]

Poking around a bit (I was interested in the higher capacity), I see 5200 and 7200 mAh batteries from a company called Denaq. Denaq's website only lists the 6 cell at 4800 mAh, but some eBay auctions say 5200. The 7200 mAh is a 9 cell battery and sticks out the front! I had no idea that any companies made something like this for the X3x series.

The number of cells is not a direct indicator of capacity. A given Ampere/hour performance may be achieved by using a (larger) number of low(er) capacity cells wired in parallel, or by using a small number of high(er) capacity individual cells in the series chain. Now, whether a small number of newest technology high capacity cells will be more, or less, reliable than a larger number of 'older' technology cells, is anybody's guess - until, or unless, some trusted authority does some research and makes a pronouncement. And I don't see one getting in a sweat to advise us poor laptop owners anytime soon ............ !

And if you followed that, you're probably more sober than I am at this time of night. It's a long time after 7.31pm!

Both my replacement and original battery have 4400 mAh, but there are many 4800/5200 mAh replacement batteries available. But I'm really suspicious with the quality of "replacements". Besides the type of used cells, their age as well as the load-control are very important for a good overall performance (which is the only thing that counts). A database with detailed information about replacements combined with experience from users and a list of reliable shops would be a great thing

[uux]

The number of cells is not a direct indicator of capacity.

I realize that. Basically, my surprise is at the fact that anything other than a battery with the original physical dimensions was made for the X3x series. I had no idea (and it never occurred to me to look for) a physically larger and higher capacity battery for the standard battery slot. IBM/Lenovo never made one to the best of my knowledge.

But I'm really suspicious with the quality of "replacements".

I've bumped into some dud replacements that make me a little hesitant to try anything other than an original battery. However, I've been using this (Rayovac RAYCL731B, 10.8V, 4400 mAh) in my X31 since around the end of September with good results.

just to share my story.

I live in Germany and recently I bought a 3rd market battery pack from ebay for my X40. Although not from the same seller as in your post but the product description is very similar. That is, it says that the battery has Panasonic cells with 5200mAh capacity (Also the way the text is written on ebay is the same). I got the battery by post and tried it right away and the battery info says that the cells are not Panasonic but FLT. Also that 5200mAh pack for X40 is big and heavy. I have a 4400mAh pack and it would sticks out from the back of my X40 about 1 inch but this 5200mAh sticks out for like almost 1.5 inch or so and its weight shift the X40's CG totally to the back

I sent the battery back right away for refund mainly because the cells info is not showing Panasonic. I was prepared for a heavy weight but that thing weight way too much for me.

Well, I hope you have a better luck than me.

'Fraid not .......

The battery arrived yesterday, and despite 3 conditioning attempts, refuses to charge beyond 25%, according to the XP readout. It then powers the X31 for only 45mins before being fully discharged. Also, the battery registers as being made by Lezinn, type 572, and not Panasonic. The label states it to be 5200 mA/H, and it is the same size as the original IBM battery, though not quite the same shape. It was supplied by NET-Electronics GmbH.

I shall now attempt to get a refund - did you manage to get one?

[kingofthehill3]

My current replacement battery for my X30 shows the following information:

present: yes
design capacity: 47600 mWh
last full capacity: 47600 mWh
battery technology: rechargeable
design voltage: 10800 mV
design capacity warning: 2380 mWh
design capacity low: 476 mWh
capacity granularity 1: 1 mWh
capacity granularity 2: 1 mWh
model number: IBM-COMPATIBLE
serial number: 39973
battery type: LION
OEM info: FLT

Btw. the first replacement I got from the eBay seller was also broken (did not load at all). Currently the replacement has 123 load cycles and only 38% of the maximum capacity Therefore I am very disappointed with the replacement. But an original battery for the X30 currently costs about 100 Euros, a replacement only 35-60 Euros. So a reliable source for reliable replacement would be a really great thing...

Tried Denaq and they wanted me to go to a reseller despite their site being to the contrary. Take that as a bit of a warning of their practices.

Of course, if someone from Denaq would like to step up and explain themselves a bit more, it'd be welcomed.

First: a beef! I'm fed up with this message response feature ......... having spent 20mins typing an input, I was daft enough to press the tab key, and the whole lot went off into oblivion. And it's nowhere near the first time something similar has happened: usually when I elect to submit a response having not ticked the appropriate 'keep alive' box in the login sequence, whereupon I'm put back to an empty dialogue response page. Grrrrr!

Right, having got that off my chest, earwigo:

Following my starting entry for this thread, and my subsequent update, fings have moved along – albeit slowly and painfully. After several email exchanges with Net-Electronics about the duff non-Panasonic battery (mine in English, theirs in German – of which I understand not a jot) I returned the duff item with a covering letter (in English) explaining the problem. I requested either a genuine Panasonic battery in exchange, or a full refund of the amount I paid. They responded that they would send me another battery, which duly arrived about 10 days later.

On first fitting to the X31, the XP battery monitor showed the item to be (I think) an IBM 08K8048, made by Panasonic, and 100% charged. Oooo, that’s better I thought, but none-the-less, I proceeded with a battery conditioning exercise using Batcal.exe to monitor the goings on. To my astonishment, after the first discharge-charge cycle, the battery monitor announced the battery to be:

Name IBM-COMPATIBLE
UNIQUE ID 1388GWIBM-COMPATIBLE
MANUFACTURER GW

I have some thoughts about that, but as I don’t fancy being done for libel or slander, I’ll keep them to myself …………………. You can do some fancying for yourselves.

I had to carry out 5 conditioning cycles before getting consistent results: on the 2nd and 3rd cycles, the battery refused to charge beyond 98% and 91% resp, but then seemed to settle and achieve 100%. Finally, I did a comparison with the original IBM 4400mA/H, From fully charged to laptop switch off, the IBM item gave 95 mins, the new 5200mA/H item, 107 mins. Given that the IBM item is probably at least 4 years old (but not heavily exercised), I’m not sure that this is a good result, but having no other basis for comparison, I feel moderately satisfied. Perhaps someone else can weigh in with some other comparison data if they have any.

So has anyone actually tried a 9-cell battery? I am looking at a couple on Ebay. For this almost tempting price ($60 shipped with live cashback) it would neat to have 7200mAH or even 6800mAH.

Wonder how the front extension would do to typing comfort.

Seconded - if anyone has used one, please speak up! I noticed them today and was intrigued, though the stock 6-cell runs pretty darn well on the X31 (and better on X32 <sniff> ) I'd like to see what it looks like.

I had good luck with a Rayovac for a T23, it came with a one year warranty and it has been performing quite well for about a year. Have had after market batteries, none did well at all for that long.

Bumping this up, to find out is anyone has actually tried the available 9 cell batteries from eBay. Looking to buy one.

[tanstaafl]

Yes, it's an old thread, but...beware!

I have tried two non-IBM eBay batteries for my X31. The first one (China seller) would not charge at all, and the second one (New Jersey USA seller) would only charge to 1/3 the claimed 4400mAh capacity. I believe that these sellers know that they are selling cr*p. eBay should clamp down on this fraud.

A good used X31 is a great netbook alternative, IF it can be paired with a nice new battery, but it seems they are hard to find.

I'm tempted to try the Ray-O-Vac battery , even thought it's 80 bucks, but I am worried that it is old stock and will have problems.

[spronkey]

Can you post the names of the sellers you've had bad experiences with? I'm currently doing the battery lottery at the moment for my X31 and for my T60!

[ParatoOptimal]

I'm looking to get a bat for my brother. I'm guessing an original with 2hrs or more per charge is good???

i bought this battery, sanyo cells, 4.5 hr. life, rated 72180, after 4 months still at 72180. the only downfall is that it won't snap into a base coz it sticks out the front about 1.5 inches. it doesn'[t restrict my typing. gives my x32 very good battery life.

i've bought a few 9 cell batteries from denaq and it's a hit or miss whether they work or not. the good thing is they have an excellent return policy. after 2 returns i finally got 2 batteries that work as they are designed.

one major downfall on aftermarket batteries is the quality of the electrical connections. i've already had a few batteries that the contacts bent upon insertion. the battery works fine as long as i don't take it out.

denaq's batteries have sanyo cells and the full charge capacity is 80310. the contacts are good quality. if you get a battery that isn't up to snuff they will sent you a prepaid shipping label along with a new battery and then you can send the old one back so you aren't without a battery. plus they replaced a defective 6 cell with a brand new 9 cell. i would do business with them again.

[topmahof]

one thing about aftermarket batteries is that you HAVE to calibrate them immediately. you have to let them discharge fully and then charge them fully or they won't work right.
