I’m the IT guy at my workplace and recently bought few of these for myself and my team: https://www.amazon.co.uk/dp/B00ODRSN0A/
Quite expensive but well worth it. Good sound quality, I can walk around entire house without losing signal, and battery lasts me for 2-3 days.
I have a Jabra Evolve 65 headsetthat I use on a daily basis. Initially the battery would last a couple of weeks between charges, but now I need to recharge it at least every day and sometimes during the day.
A replacement headset costs over £100, and a replacement battery about £10. I’m more than capable of physically replacing the battery, but I’m nervous about the risk of using an unbranded replacement and would welcome advice.
The battery is a small lithium ion one and the original has three wires (I believe the 3rd is connected to a thermistor inside the battery as a safety measure). Most of the Li-ion batteries with the same specs (3.7v 280 mAh) have just two wires, but I have found one with all 3 on Ebay where it is touted specifically as a replacement for the Jabra Evolve 65 battery.
This battery is completely unbranded and from a Chinese seller. I know literally nothing about it, except that I’m pretty sure the text that appears on the batttery in the Ebay listing has been added after the photo was taken (and the QR code simply repeats that text).
I’m somewhat reluctant to wear an unknown Li-based battery an inch from my temple, or to leave it charging unsupervised. However, I’ve been unable for find an alternative replacement so it’s either this battery or replace the whole headset.
Am I being unnecessarily jumpy here, or is my caution well founded?
