Increase Play Time of MP3 Player




About: Engineer by profession , love to meet people , travel around the world ..

I purchased a mp3 frm local market , but it hardly plays for 10 - 15 min and then
I had to recharge it .I found that it uses cheap tiny rechargable battery ,
which was nothing but scrap , so I thought to replace it a higher amps battery
so that it runs for hours


Step 1: .

Open the mp3 player , carefully , it will be generally just glued at bottom , so a little effort and it will open

Step 2: .

Once you open it , you will find the battery , and speaker wires , disconnect them.
you will be amazed to see how you were cheated with this tiny battery  

Step 3: .

Now you have to get the very thin wires to get soldered the speaker and your new battery (3.6 volts , ni mh , 1ah ) or any spare battery which you have , only thing you take care is , voltage , must be 3.6 volts

so get the thin wire , best is you cut any usb data cable , and you will get best cable there

Step 4: .

Solder carefully the new battery , and also connect the speakers , (little bit longer wire )

Step 5: .

Put back the mp3 case , please be careful while taking out the power wire , i took it out from the usb gap
connect the battery and power on

Step 6: .

Now the mp3 player is ready , you secure the battery ,
i tied to the device itself as it is handy and ready to use
Now my mp3 runs for very very long with one charge

    If you wanted to retain the original look, measure and replace the battery with a NEW li-po cell. Odds are very good that the one you bought was sitting in some hot warehouse or shipping container, for an extended period of time, and with an insufficient charge.

    Sort of like when you buy the 3xAAA flashlights WITH batteries for the same price as the version without batteries. Just assume you will have to replace it.

    Hi Smiter,
    the basic idea is to check the power source , and take it out so that it becomes easily to manipulate , once the battery is out , you can use any battery which is with you , personally I prefer NI-mh Because , there is no issue with over charge , while LI PO battery must be HANDLED VERY CAREFULLY , else they blast or over heat ..EVEN BOING DREAMLINER IS HAVING OVER HEATING OF LI PO for your info..cheers

    Thanks for sharing this. I have an MP3 identical, but when I try to open it as you made, it seems the buttons prevent the opening. I can open it only 2 or 3 mm. ¿Could you tell what is the problem? I don't want to ruin it.

    Hi Rimar,
    It is stick with adhesive as I mentioned in step 1 , just little care you have to take as some times the push buttons may obstruct the opening , also remove any micro card in slot ..

    Yes, but the adhesive is stronger than I expected.

    For now I only fastened the battery using two little rools of masking tape. The battery was loose, grasped only by the cables.

    I don't understand how they can produce a FULLY MONO MP3 player. The sound is good considering the size, but being mono it loose the best of music.
