3.7V 803040 1100mAh Rechargeable Lithium Polymer Battery, Suitable for Turtle Beach Elite 800 Elite 800X Stealth 700 Gen 2 Wireless Surround Sound Gaming Headset，DIY 3.7-5V Electronic Products。

I was worried when my Earforce Tango's started to only hold a charge for few hours. I'm not sure how old they are, but I love that headset. This battery pack fit the previous battery location without any modification to the headset. The battery is located in the charging side of the headset and there's a total of 6 torx screws to access the battery. There is not a 3 pin connector on the old school Turtle Beach headsets. The wires are directly soldered to the board, so plan on soldering directly to the board or cutting the old wires and soldering those to the new wires. The old battery had Black-Yellow-Red wires and the new battery is Black-White-Red. Simply substitute the white wire for yellow. I used a plastic pry tool to gently pry the old battery out, which was held in place with double sided tape. Hope this helps someone out, it's definitely worth doing.

My headset would die after 2 hours and bow it last 10+ hours. Works vetter than the original battery and is a direct fit.

ユピテルYPL502Si(ナビ)が使用不能状態のため、ばらしたら本製品が純正品と同等と思われるため購入し、ハンダ付で交換しました。現在のところ問題なく使用しています。本製品のほうが純正品より厚さがありますが何とか収まり、現在耐久性の様子を見ております。

It was a gamble that paid off. I bought the battery pack as a replacement for my Turtle Beach XP 800 pro headphones. It fit perfectly, but make sure you have a little piece of double sided tape handy. The connector was even the right one. No need to solder the old one on. Couldn’t be happier.

商品ページに寸法が出ていたので助かりました。３線仕様だったので選択肢が少なかったですがばっちり交換できました。 交換後は1時間近く駆動できるようになり、交換した甲斐が有りました。 交換前は3分と持ちませんでした。
