Here is a link to the Ifixit guide on how to remove the battery.

Jawbone MINI JAMBOX Battery Replacement

Unfortunately, searching for the battery by using the part number, shown on the battery in the link, does not give any results regarding a replacement battery.

You may have better luck in obtaining a battery, by actually measuring the dimensions of the battery and including them in your search criteria.

For example, and to my knowledge this is not the size of your battery, if the battery is 4.2mm x 50mm x 30mm (HxLxD) you could search for a "425030 3.7V 900mAH 3.3Wh Li-On Battery" and see if there are any suitable replacements.

Be aware that a lot of the batteries of this capacity (i.e. 3.7V 900mAH 3.3Wh) on offer seem to have a 3 terminal (or wire) connection whereas the pictures in the link above show a connecting flex cable having only a two (2) wire connection. So if you wish to adapt a suitably sized battery of correct capacity and voltage as a replacement take note of this and connect to the two correct wires or terminals.

Hopefully this is of some help.

I just bought one with a bad battery on ebay. I am planning to measure it and attach the wires of a matching off the shelf battery. I was hoping to find the dimensions before it got here but I can wait.


Any luck on a finding? My 5 yr old pulled the flex cable while i was cleaning it since i found it at a park. Can precisely taping back the flex cable work?

I installed a $6 “similar enough” battery from eBay. I have added steps to the procedure, you may have to “switch to the Unverified Version.”
