3rd party extended Battery guide

3rd party extended Battery guide

We have put this guide together to help people who opt to use 3rd party high capacity batteries that can be found on various online marketplaces.

List shows compatibility in terms of fit and what depth case back is required (thick or thin) to achieve correct fitting.

Please note: This article is NOT a recommendation for these batteries, there seems to be a very high level of variation in the quality, capacity ratings (actual & advertised) and more importantly we have seen different size batteries supplied for the same advertised product!!

So you have been warned – this article is for information only and the said information is provided with no warranty or promise of accuracy. Your results may not reflect our findings!

There are couple of more batteries I have seen, and once I have managed to obtain some samples this guide will be updated!

Notes

Remove frame protusion for 1900mAh battery

Remove frame protusion for 1900mAh battery

(1) When fitting with a thin caseback the protusion on the iPod’s inner frame needs to be removed (as pictured).

(2) We have had some samples of these batteries which actually fitted (read: tight squeeze) in a thin (5g) caseback & the iFlash-Solo.

(3) This battery is larger than the iPod’s inner frame, it will ALWAYS require a thick caseback. This battery can be awkward to fit as it interferes with the headphone jack assembly, you may need to lift the headphone ribbon away from the rear case to allow the battery to slide under the headphone jack assembly.

(4) This is based on current energy density of li-ion based battery cells, it is a very approximate (gu)estimate as the volume measurement is based on external size of the battery pack and not the actual cell size. Other factors which may effect the accuracy is the method and quality of the cell construction and wrapping. However, it is a great method to see relative capacity claims when comparing by volume of the battery cell, of course the chemistry of the batteries need to be the same.

(5) We have seen this battery sold as 1800mAh and as 1600mAh, all examples we have seen have been a similiar size. At 5.3mm thick this battery will always require a thick caseback, and will not fit with the original HDD.

    No.
    (1) I opened the Ipod 7th gen
    (2) I Exchanged the HD with a I-flash Quatro with a 256gb microSD
    (3) I Exchanged the old 650mAh battery with the new 2000mAh battery. I removed some plastic from the battery to make the flatcable longer and connected the flastcable to the Ipod
    (4) I closed the Ipod.

    It was a very easy Job. Opening the Ipod can be difficult, but with the right tools and this instructions (https://youtu.be/4AF1Pjbwc6c)
    Good luck Pandit

    Pandit-

    Did you have to buy a different headphone housing for the 7th gen thin with the 2000mAh battery?

  3. Hannibal

    Help!!! I am performing a ‘big’ battery upgrade on a 7th Gen. This requires a new (thick) back cover with a new hold switch/headphone jack flex cable. The tab on the flex cable 1/2 inch from the switch has an exposed conductive pad…. which is normally presses against the metal case by the original battery and lightly glued from the factory. This appears to be a ground. The new battery fits differently than the original and does NOT press the tab to the case. As such, should this tab be glued with electrically conductive adhesive? If not, why is the pad exposed?

    “A black faceplate, because mine is full of scratches, scuffs and cracks. So far I could only find on eBay Chineese knockoffs of poor quality. Could somebody tell me where can I find a good quality replacement front cover (faceplate)?
    Thank you in advance”
    I ordered this one, for my Ipod 7th https://www.ebay.com/itm/1TB-Thin-Metal-Housing-customizing-Back-Case-Cover-for-ipod-classic-Black/184081471135.

    I want to change my 10 years old Ipod Classic 6th gen to a gold one for my wife’s birthday, there is choice, but which one is really good? I have the same question as you..

  5. Pandit

    @Support, Thanks for your information. I think I put the ribbon cable under the battery. I will open it soon do do your recommendations and to add extra memory, As you can see I put only one micro ssd in de I-flash quad and there is space for four 🙂

    @Pandit – With them batteries, the recommend way is to install it upside down, and crease the excess ribbon over the top of the battery.

    Yuo will cause undue stress on the battery connector trying to fit as you have shown, as the ribbon is too short that way.

    In response to Pandit:

    I am currently upgrading with the exact same battery that you have bought, with an iFlash Quad, in a slim back. I am just waiting for the battery to arrive now (how long did it take for yours to come?). I was wondering if you had some more specific details on how you installed or potentially some photos which you could share with me?

    Thanks in advance,

    JT
