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!

Fitting Guide (see numbered notes below)

Battery iFlash-Quad iFlash-Dual iFlash-Solo iFlash-Sata iFlash-CF
 2000mAh Thin back Thick back Thick back (2) Thick back Thick back
 1900mAh Thin back (1) Thick back Thick back (2) Thick back Thick back
 3000mAh (3) Thick back Thick back Thick back Thick back Thick back

Battery Specifications (for samples we obtained)

Battery Image Size (mm) + volume Observations / Notes
2000mAh Battery 2000mAh 46 x 90 x 4  (16.5cm³) Capacity based on volume estimated at 1700mAh (4)
1900mAh Battery 1900mAh 54 x 80 x 3.8 (16.4cm³) Capacity based on volume estimated at 1700mAh (4)
3000mAh Battery 3000mAh 57 x 83 x 3.6 (17.0cm³) Capacity based on volume estimated at 1800mAh (4)


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.

    I have an iPod Classic 7th gen and I am doing my research for an upgrade. I will probably buy an iFlash-Quad and 2x SanDisk Ultra 200gb. I think is the best balance for longtime and speed. I also don’t like SSD’s vulnerability for storing data when are without power for a long time.
    Anyway, I’m now investigating the best battery upgrade but it seems that the 2000mah is not available to ship to Europe. At least the one from eBay.com shipped from china. Maybe is the new IATA rules for handling lithium batteries on Planes in Europe?

    @Tony – There is no room for the foam pads in that configuration – everything will be held tight just by the fact that it is a tight fit!! The iFlash-Quad and the MicroSD’s do not product much heat – so there is nothing to be concerned about in that respect.

    I have a simple question: When installing an iFlash Quad along with one of these extended batteries into a thin back case, is it necessary or recommended to use the foam or any other sort of padding or insulation? Or is it just fine to have the battery lay right on top of the iFlash?

    It doesn’t seem like there’s room for any padding, but I’m just a little concerned about having the battery laying right on top of the controller and the microSD cards/slots due to heat when the iPod is being used heavily (or when syncing for the first time). Is this a needless concern?

    Any advice will be greatly appreciated. 🙂

    Hello Tarkan
    I asked this in 21 of June : could you provide a smal power supply circuit which can provide enough current to an Ipod without battery, even for powering up the Ipod?
    It could be very useful for domotic audiophile / home use
    Thank you

    @Les Garten – No we do not sell batteries due to heavy regulations surrounding the shipping and posting of batteries – while Chinese sellers are happy to totally disregard and ignore these rules we cannot and would not.

    If you are keeping the thick case back then any of the batteries shown in this article will be ok – I think majority of users tend to go for the 2000mAh as that has been around the longest.

    I read elsewhere that you guys sold batteries but it doesn’t seem so.

    I have a Gen 5 with thick back that I would like to put an iFlash Dual in.

    Any recommendations for the biggest and best to put in there?

    @Garrett – if I remember correctly that is what we had to do to fit that battery. The FPC will be ok bent back like that.

    Thanks! I got it installed, but am still rather scared and skepitcal because of the orientation of the battery as to how the flex ribbon fits into the logic board, the ribbon is having to nearly bend in half if that makes sense. I have attached a picture which I took previously before I got it fitted. http://i910.photobucket.com/albums/ac302/garrettgoerl17/IMG_1833_zps5uuhydjp.jpg
    I’m just worried of putting a kink in the ribbon cable for the battery and breaking the connection. So I’ve left the top of the case off for now. Also, why does my ipod say the battery is full when charging and when I disconnect it says it’s only half?

    @Garrett – The 3000mAh can be awkward to fit, you need to play around with it to fit correctly, try removing the pad underneath the jack socket.
