iriver H340 Battery Upgrade
July 3rd, 2007 Posted in TechI went to the new Maplin store in Derry today and got a replacement battery for my mp3 player to boost its running time.
I got an iriver H340 a couple of years ago as it was one of the larger capacity hard disk based players at that time. The icing on the cake for it came a year or so ago when I discovered Rockbox for the H3xx series. It’s an Open Source jukebox firmware that supports a raft of different players (to various degrees). It’s also rather good once you get it set to your liking with a decent theme and the like giving you far superior functionality over the stock iriver firmware which is very lacklustre indeed.
The new battery is larger capacity that the stock battery (2200mAh vs 1300mAh) so should see a decent increase in battery life. I just hope the larger battery doesn’t heat up overly or get damaged by the snug fit inside the iRiver case. I followed this guide to do the deed. Probably the fiddliest, most awkward and stressful piece of modding I’ve done.
Sorted now, after some false starts reassembling the device. I had to reconnect the old battery as I got no life from it when I first hooked up the new battery. Then when I realised it was still alive, I went back and tried the new battery again and got it to boot. I also had to go looking for how to load the stock firmware as there is a limitation to rockbox not lighting the LCD without first booting the stock iriver firmware.
