So there are two batteries in this headset that need to be replaced?

Doug Green - Reply

Also, what battery do I purchase and does anyone know a good source to purchase them?

Doug Green - Reply

Max battery size: 50x36x9mm

Origina battery: 40x30x8mm

The pcm board can be replacement by old battery module.

Only one battery inside. Not sure why this guide takes appart the whole headset.

All steps&pictures related to right side (step 1, 2 and 4) are misleading and unnecessary when doing just battery replacement.

I ordered replacement on aliexpress.

What part number please and thank you in advance

Look at Hixon 3.7v Rechargeable Li-polymer battery for MP3. Specific size 40×30×8mm. That looks to be the correct battery.

Hello, I purchased this battery for the replacement on the 800x but it takes a bit of modification.

1200mAh Extended Battery for TomTom One IQ, V2, V3, V4, XL & XL-S GPS Devices (Not compatible with any of the TomTom One N14644 GPS Unit).by MPF Products®

I have tested the headset at full volume and with 2 devices hooked up on bluetooth.

The battery last for about 10-11hrs in till it powers down…… I included a link down below to a drop box folder with pics to give a better idea of how I did the modification.

I found this battery, would it be ok to use? VINTRONS Rechargeable Battery 1200mAh For iPOD 4th Generatio, 616-0183 https://www.amazon.co.uk/dp/B00KG71XZI/r...

that might be a bit to long… I had to cut out a little of the plastic toward the bottom to fit the battery that was was 45mm long, 34mm wide, 8mm thick.

soakman707 -

Why did the TomTom battery you purchased require modification? It looks like you bought a 3pin battery, and the turtle beach headset was already a 3pin connector. Where the connectors actually different, and the battery connector purchased off amazon didn’t fit into the headset board?

Patrick Hague -

I did this and it works great. You do have to trim the plastic for proper clearance since the battery is a bit larger. You have to cut and solder the old battery 3 pin connector to the new battery because they are different sizes. But other than that works great. Thanks soakman707

Marc Johnston -

Can you just pop the pins and swap the connectors?

Nathan Ross -

Ok thanks for getting back to me. Which of the dimension was to big, 45mm? Or 35? I’ve been having a good look around, had no idea it would be so difficult to source a battery lol. The post above dated 19/10/17 regarding dimensions, do you know if the original dimensions are accurate?

John - Reply

51mm is to long. The PCM board with 3 pins(if u have old battery) can be replacement to the new battery. So u don't need 3 cable in new battery. All batteries are the same, only PCM board can be different and pins size.

Cables in original battery:

Thanks for the advice, I think I've found one that will be perfect.

I put a new one in that’s 1500mAh and it lasts a long time. I bought it from a Chinese battery manufacturer and the size or part number is 903040 (9mmx30mmx40mm). Just needed to solder old battery circuit board to new battery.

I'm modifying to external 18650 battery 3100 mah should last 36hrs

Can you give link where you bought that battery?

Just did this.. took all of 10 minutes not including the time it took for the iron to get hot. To replace the battery you only need to work on the left side as said above and you don’t need to de-solder anything from the board. Skip step 4!

In order to keep the battery from rattling around you need to use some double faced foam tape and apply it as it was done on the original battery. Be sure to use heat shrink tubing when you splice so you don’t short against the pcb board.

Works great!

PS: if you don’t want to get inside the headphones to replace the battery just use a standard usb power bank battery and stuff it in your shirt pocket. Works for hours and hours! I did this for a month waiting to have the time to do the replacement.

I replaced mine with a 1500mAh and here are the details if someone wants to contact the supplier.

Warning just use old circuit board as you need all 3 wires for it to charge.

I contacted the lot your are talking about and yes they do this battery and I ordered one and installed it today. Yes skip step 4 and did the following specific for this battery only: Desoldered the old battery cards off each battery and swapped the old 3 wired battery card onto the new battery and installed it as per the steps above in guide. At this stage it works completely fine including charging. I will leave another message here after a month to update you all on its average battery life.

Any one in the uk managed to source a replacement battery for the 800x? Most of the ones I’ve seen look to only have 2 wires instead of the 3 on the current battery. If need to do something extra with regard to reusing the existing 3 pin connector can someone provide some instructions for this too? Any help would be greatly appreciated as I’m no expert when it comes to these things :-)

I’ve gone ahead and ordered 2 off ebay and hope they are fine and will work, the 2 I’ve ordered are:
