LG's draft spec for the battery? (from 18-Dec-03)

Been reading old posts and saw the m3 battery markings "lg52345ob1"
I change to o to 0 or zero and googled it...

http://www.visualvoice.net/Datasheets/LG/LG523450b1.pdf

Describes the battery as "model: ICP523450 B1 1000mAh (Tentative)" and has drawings, exact measurements etc

But, google the model number and find...
http://battery.swgd.org/lg.htm

specs
ICP523450B1 1030/1000 4.8 34 50 China
(model Capacity / (mAh) Thickness / (mm) Weight / (mm) Length / (mm) O.M )


wonder if this is the m3L battery?
ICP103450L1 1900/1850 11.4 34 50 korea
(model Capacity / (mAh) Thickness / (mm) Weight / (mm) Length / (mm) O.M )


ahh google again with "ICP523450" ie cut off the B1 and plenty of hits...

I just can't believe that no one sells a battery for this thing.


Should I just go ahead and send my player in at the end of the warranty term to get a new battery? How long do these batteries typically last?

[sknight]

It would be a lot easier for someone to do one of two things:

1. If there's a broken x5 out there, disassemble and then speak to a battery importer/supplier, such as www.batteryspace.com . Surely, the catalogs they go by are huge compared to what's on the consumer level. Send them the battery and see what they could come up with.

2. Remove your battery anyway and do the same thing.

I can guarantee that eventually a replacement will be sourced or made from the Chinese supplier.

How can you do that? I don't know how these things work but then again X5s are not as popular as iPODs or have a user replaceable battery like other DAPs.

Here's an idea though:
How about starting mass-mailing some suppliers requesting a battery? Looks that more and more people are experiencing short battery life in here..

[Zeus's Uncle]

If you all haven't seen the pictoral instructions on how to replace the battery, you should checkout these two posts by bertd.

i was checking my Sony Ericsson phone's battery, it has a 3.6v 900 mAh batery, type: BST-37, dimentions are in mm: 5 x 4.8 x 3.5

its used in phones like the k750i, w800, w810.
and it isn't heavy at all, 20 grams at most.

so its small, should fit in the x5, is a slight bit less powerfull, but in my phone it can charge in about 1,5 hours, maybe even a bit less without getting warm, estimated 35 to 40 degrees celcius at most, never took a measurement of that :p

edit: its a Li-Polymer btw.

[u4ik]

3.6V should be fine for the X5. The unit altogether generally uses a voltage around 3.8-4V, though it should accept marginally lower voltages.

Hi
I recently called the german custumer service line and spoke to a technician and he told me cowon could replace the batterie for free (if i could find the bil of when i bought my x5l) or for a charge of about 15 bucks...am I missing something here or do you guys want to put in a batterie that has more capacity than the one the technicians would put in....

[Getwired]

Well, I for one don't want to risk mailing "My Precious" anywhere. I'd rather open 'er up myself and attempt to put in a higher capacity battery. Problem is, I'm a big frickin' chicken, and don't want to void my hardware warranty prematurely. I'll let someone else who's out-of-warranty try this and post their results first. (Yeah, how nice of me I know.)

Does anyone know if there's any extra room in the X5 (non-L version) around the battery? It's hard to tell from the photos posted here and elsewhere.

Also, I see these posts of people wondering about using cell phone batteries. What I'm wondering is if there's someone who's truly tried a cell-phone battery and can comment on whether it really works. Assuming of course it didn't burst into flames upon charging or whatever. They seem to be pretty easy to come by online (eBay and stuff), so that'd be pretty sweet if I could identify a make & model to get.

Can someone please tell me what the chances are of safely running a Polymer Li-Ion pack rated for 10A drain rate in my X5? Battery Space has this item that might work -- it's pretty darn close to the correct size, and it's 1050 mAh. BUT, will the thing melt down if it goes into a presumably slow-drain device (relative to an R/C airplane) like an X5?

[Getwired]

Sorry for the extra post here, but you really do need to check out this post and this continuation. It's amazing what you can uncover here just by doing some reading/scrolling UP. Geez I must be BLIND.

[Zeus's Uncle]

Heh, scroll up a little on the page getwired check out my previous post

Oh man, if this isn't the most ironic post. Next hint after scrolling up, finish reading the post before you reply to it. (that's for me)


Did we just do a DOUBLE BLIND test?

[theundead]

Does anyone know the SIZE specs for the X5L
Or the manufacturer model code?

Hi,
I had contact to the German customer service in Frankfurt about a year ago, but last time I wrote an email no reply ever came- could you post telephone number, email adress or anything of that like, please?
Would be much appreciated,

bye and thanks!

hey guys

I've read tons of posts about batteries being sold on ebay with fake capacities listed on a fake label so I took apart my cell phone battery from my Motorola E815 and once I removed the plastic cover, the size is 5.9x42x33mm so it should fit according to the post noted below. the sticker on the batt says 1030mah 3.6v and it’s a oem batter so I assume its not a fake. I just thought this might be an easy alternative to other batteries mentioned since the e815 is a VERY common phone. I dont know if this is the best option but it is an option. I know its not a huge capacity but it might be a little better then the original. I'll post again once i find out if it works.

once again.....

Motorola E815 battery
size. 5.9x42x33mm
1030mah 3.6v

So the max for this size is : 1011.85 mAh

By considering that I also measured the battery box, I still thing that 950mAh is the best we can have.
