suitable and cheap battery for iriver H140

<< < (2/2)

GodEater:
I think I ended up trimming the two "guides" on either side of the connector back to make it fit. Also whilst drunk. I'm so proud :)

[410] Is it possible to change / upgrade the internal battery?

Yes.  This requires opening the case.  The original Li-ion battery that ships with the iriver is 1300mAh.  You can choose to replace it with a similar capacity battery, or upgrade up to 2200mAh.  All you’ll need is a torx T5 wrench and some time..

There are handy pictorial walkthroughs here  and here.

Important: Please note that ipods have reversed polarity from irivers, so if you use an “ipod battery” you’ll need to reverse the battery wires at the molex connector.

Warning: Before you swap your battery, I must insist you watch these two videos:

Video 2

I'm not trying to scare you, but you must be made aware of the risks of a damaged/incorrectly installed battery.  At least one person over at misticriver.net has reported that his battery swelled and destroyed his iriver.  Having said that, many people have done this mod with no issues (myself included, several times over).

In addition to the info in the walkthroughs, here are a couple of tips I've found handy replacing my iriver batteries:

Once again (its worth repeating), if you're using an ipod battery, do not forget to reverse the wires.  With the molex flaps on top, the red wire should go in the left side of the connector, the black in the right.

The most difficult part of this process is pulling the original battery's molex connector out of the board because the dc connector sits right behind it, which doesn't leave you with much wiggle room.  I suggest, use a tiny flat-headed screwedriver to pull the connector out as far as you can, then use the same screwdriver to gently apply upward pressure to one of the bottom corners of the connector.  Just be careful not to touch the board with the screwdriver - you shouldn't need to touch the board at all with it.
 
To make it easier to get the new battery molex connector into the board, you may like to carefully shave off the bottom 'lip' of the molex connector with a razor to make it easier to slide in.

I didn't notice, but hyperplane mentioned the molex connector on the original battery has a smaller lip so it might be easier to transfer that onto the new battery.

Once you're done transferring the batteries, you might like to wipe down the inside of the iriver screen with a soft cloth (i use the cloth that i use to clean my prescription glasses). Dust inside the screen is really irritating.

When you're putting everything back together, ensure the hold switch nestles into its notch, otherwise it won't work.  You'll see what I mean when you're there.




[420] Where can I buy another internal battery?

Most folks seem to pick them up from EBay for ~$20.  The specific model I’ve installed in multiple units with no hitches is the UP325385A4H. These are typically advertised as 1st and 2ns gen ipod 2200mAh batteries.

Interestingly, this exact battery model is now selling at my local Radioshack equivalent in Australia...so you may like to try Radioshack before hitting up ebay.

I bought last week a 2200mAh battery for my h140 here: www.ipodrepair.nl for 16,50 euro (inc. shipping costs). Maybe they also ship to german....? I only swap the wires and it runs fine now ( +/- 27 hour with Rockbox!!!)
