I've had this Hip Street mp4 player for a while now. It, Like a lot of mp3/mp4 players has a built in li-ion (lithium ion) battery. The play time has never been great. but lately I've pretty much stopped using it because it's deteriorated so much, its down to about 1/2 an hour per charge....no good.
so i decided to do something about it

Step 1: The Guts

Was a very simple disassembly 2 tiny screws, and the lid popped off, revealing the guts.
<p>Thanks for such a great tip on how to replace the battery of this gadget... Done with it successfully and I was able to follow everything carefully. However, I just want to ask something I noticed...</p><p>Does is it really have to take very long before the battery gets fully charged? It's because I noticed that I have been charging the battery for a few hours now (approximately 4 to 5 hours), but it seems that it will take long before the battery gets filled-up. I admit that the one I used as a replacement was totally drained.</p><p>I hope to hear your opinion about this even if this post of yours was posted a very long time ago. Thanks. :)</p>
not so easy to do with mp3 players that have batteries similar to cellphones (no wires)
yeah, but then you could just buy a new battery, right?
did the same idea for my palm zire 31 with a ds lite battery, unfortunately, the battery was old and has died, i'll look to find a 2000mah dsl battery to replace it with.
haha! nice! I am doing the same mod as I am typing now... the battery is a Sony Ericsson BST-36 750mAh but it doesn't fit very well... I smashed it a little to flatten it a bit... later, I might smash it some more...
Great instructible! I have a few questions though:<br /> <br /> Would you think this kind of replacement will work with a Nokia Battery(i.e.&nbsp;BL-5C or other BL-Series and other variants of it) or any other cellphone battery? <br /> <br /> The Nokia Battery has no protection circuits(obviously the nokia cellphone has the circuits), will this guide still help?<br /> <br /> Thanks for the great instructible, I may use this guide as I have an mp4 which is quickly degrading on playtime.<br />
Many thanks for your indestructible ! Maybe I missed it, but how long does it last now?
(excuse for English but I am Italian) but as you have made to close it? however compliments, it's really cool..
i didn't have to mod the case to close it, the side just swelled/bent out a little, i may order a different battery for it, I was looking at an old phone i have, Motorola c332, the battery in it is Really thin, 4mm, and its 750mah..so i may replace it with one of those off Ebay for cheap
Nice job! How much time do you get now from a full charge?
it was going for aprox 13h, then i wanted to put a new song on and plugged it in and forgot about it...so it recharged....but 13h hours is about 9h longer than i got from it brand new
That is awesome, congratulations!
