Title: iRiver H120 Battery Problem
Post by: Alexffc on April 03, 2007, 02:16:03 PM

I've had my iRiver H120 for about a year now and in the last few months I've noticed a problem with my battery and just wondering if it's just a battery getting old or something else.

The problem is - I'll charge the player up and everything is fine and I'll use it for a few hours for two days in a row. At the end of that I'll turn the player off with about 40-60% battery life.

The next day I come to use it I'll switch the player on and it will flash 0% life left. At this point the flashing 0% will rise slowly to 40-60% after about 5 minutes or say that the battery needs charging after about 5 seconds and switches off - even though the last reading it gave the day before was 40-60% life left.

Now I've noticed that whenever the player gives a voltage reading of anything under 3.80V on boot the player will ask to be recharged.

What I've found though is that if I plug the player into my computer and turn it on, delaying the boot process, this gives it a bit of a chance for the voltage to rise and thus when I remove it from the computer the battery life will start at about 20% and then rise to whatever it was when I was playing it fine last time.

This has been happening with all the builds for the past few months and I'm currently using a build from a few days ago, so I don't think it's a code problem.

So I'm just wondering whether this normally happens when a battery is on the way out, or maybe it's a loose connection or something.

Sorry for the long post, thanks in advance for any advice.

Sounds exactly like your battery has more or less had it.

Buy an replacement 1st or 2nd Gen iPod battery, reverse the connector on it, and fit that instead. There's a guide for how to do this over on the misticriver forums.

I did it a while back now and replaced the original iRiver battery (1300mah) with a shiny new 2200mah battery and get nearly 40 hours playback now!
