Hi,
There is this one.
I know it says it is for a Kindle 4 but it seems to have all the right numbers and specs except that the part number seems wrong but has same numbers in different order.
Zoom in on the numbers on the flex cable and check that as well.
For the cost it may be worth a try
Hi,
My only suggestion now is to measure the dimensions of your battery and then search online for a (insert dimensions) 3.7V 890mAH LiPo battery and check if there are any with a similar 3 wire connector.
The convention with batteries sizing information (and I'm surprised that it is not written on your battery) is as follows
The depth (or height) x width x length all in mm.
Also the depth number normally has a decimal point, which is not shown in the number.
An "example" of what I mean
Searching for a 354448 3.7V 890mAH LiPo battery would give results.
decoding "354448" dimension information
35 =3.5mm depth (or height) Note the decimal point
44 = 44mm width
48 = 48mm length.
You don't have to be that accurate with the measurements as long as it will physically fit into the device, especially the height.
As long as the voltage of 3.7V is correct then even the mAH value doesn't have to be exact. The greater the capacity (mAH), the longer the battery will last before it has to be recharged. This means of course that it will also take longer to fully charge again.
Hopefully you may be able to find a suitable replacement battery using this method
