Re: New battery transplant from Ipod nano it works fine
 

I'd be careful as you are dealing more than likely with a multi-layered board. So you may not see traces on the board but it could be layered between the board.

Re: New battery transplant from Ipod nano it works fine
 

Cutting the board went well as it was not multi layered. The battery fitted in however it was obiously a tight squeeze as one of the screws that holds the front down punctured the battery. This resulted in a lot of heat but fortunatly no damage to the Player. The 400ma is proberbly to big for this player as cutting the board any further will damage the circuit.

Be careful when replacing batteries!!!
 

I also replaced the battery in my chIpod with a new 400 mAh 3.7v battery I bought off of ebay. The install went well and it worked fine for about three weeks, until one day I picked up the player to use it and all of the buttons on the front were frozen. I looked at the case and it appeared that someone stepped on it, it was deformed. I took the back off and I found that the battery had balloned up. The increase in size caused the whole case to deform and put pressure on the front buttons making them inoperative. I contatced the seller in Hong Kong and he sent a new one ASAP. From what I have now learned this could be dangerous as the balloing is caused by gases building up in the battery. The cause?? No one really knows why, some specualte soldering problems, others say charging problems (ie cheap chargers sent with these cheap players), others think cheap batteries that have contamination in the cells during manufacturing. Bottom line- they can explode (go to youtube and search overcharged lithium polymer batteries)if overchaged and not designed to allow venting of the gases.

I have the new battery, but am very reluctant to install it. I think I will retire my chIpod after a full two months service, and bought an iriver clix instead. Sometimes its worth spending a little more money for a name brand. Anyway I just wanted everyone to be careful if you decide to replace the battery, if you do I would suggest buying a battery from a known seller!! and avoid Chinese cells!! Very low quality.

porrmans ipod , you were lucky! The balloning was caused by over-charging the battery.

Good batteries have a built-in protection circuit to cut off the power supply when 4.3V have been reached, and as well a mechanical vent to release excess pressure when over-charged.

Well, the cheaper alternatives might have the protection circuits, but probably lower quality. And they might not have the vent, and the oxygen built up causes the balloning. Plus excessive heat is also produced. Heat + Oxygen = Fire!

I guess it'll still be quite safe, as long as you don't leave your player charging longer than it is supposed to be.

HI,
About the charger for these cheap Nano Knock offs??
I got one from Uxcell and the charger head is from (obviously) oversesas and they also gave me an Australian adapter for it to be compatable.
My battery is really dodgy it does not hold a charge for more than half an album or so, i am thinking of getting a larger mAh version to put in it. The factory battery is only an 180 mAh 3.7v, not worth a crap actually.
My player is also a newer FW type, the 9.0.48 which is not compatable with any FW updates yet, would a FW update fix any charging issues???
any help would be great.

Cheers

Joffa , generally any firmware update would not improve the battery usage significantly.
Like you have mentioned, your current version would be extremely hard to recover at this moment.

What i could suggest would be to replace the battery of the player.

Cheers Lattesurf

Yeah I am just going to replace the battery!! I am going to be really cheeky and ask Uxcell to send me another battery, the 330 mAh one they push for a nano replacement under the ipod section on their site, its about $6 - $7 Aus dollars plus postage :shock: i do have a $5 voucher :lol:

can only try I guess :P

cheers
