XINLANTECH 800mAh Rechargeable Lipo Battery Replacement for BlueParrott S650-XT, B650-XT Bluetooth Headset, Jabra Evolve2 75 MS UC PC Wireless Headset, for Vtech Snom Headset Battery Pack

Let me begin by saying I normally do not write Amazon reviews, but I figured I would make one since there is little info out there regarding ultra custom batteries. I ordered this, unsure if it would be compatible with my pwnage ultra custom mouse. The original battery (pictured outside of the mouse) was bloated and did not hold charge. The new one installed easily, even though the connector appeared to be slightly different (new unit has holes for rectangular pins, while the mouse has round pins). The battery still fit in the connector and the mouse functions as it should. I will update if anything changes, but as of right now, I am extremely pleased. Highly recommend ordering here, rather than through pwnage. Speedy shipping, seemingly comparable quality to the original. It’s like I have a whole new mouse!

replace my battery in blue parrot 🦜 650xl works great 👍 stay charged for a week!

Loved the price, the quality saw far and it arrived very quickly. There is absolutely nothing I dislike about this product.I’m in a wheelchair and it allows me to use the headset it went in and keep my hands free.

Good battery replacement for blue parrot 450 headset. Original battery only lasted about 2 days and got swollen

I installed this battery in my BlueParrott b350-xt about a week ago. I haven't had any more random shut downs of the headset so far. Hopefully, that remains the case.

after full charge it keeps energy only for half an hour. it seems to me they are selling old ones

The price was right. It is identical to the one in my headset.

Battery isGreat, but the headset is very difficult and time. Consuming to get to the battery.Poor design headset.
