I can't seem to find any direct replacements, but one thing you can do, is to measure the battery's dimensions, then search online and find one that's as close as you can (note that millimeters matters!). · It needs to be Li-Ion rechargeable, 3.7V, but the mAh and Wh ratings aren't that important, as long as they're not significantly lower.

r/LogitechG on Reddit: Problems with G733
November 27, 2025 -

I recently had problems with my g733, it works normally while wireless, but when I try to charge it with the usb cable, the battery level in the ghub suddenly rises to 86% and remains fixed at that value, and if I try to use it while charging it starts to make the wind disconnection noise and become inactive randomly like every 5-10 seconds, I've already tried reinstalling the ghub, resetting the headset to factory settings but nothing seems to work, If anyone has been through something similar, help would be greatly appreciated, thx everyone, here`s a video of what happens, Jump to 0:34 to see it happening (sorry for bad cable managment lol)

r/LogitechG on Reddit: G733 Battery Problems
December 16, 2020 -

Short version: I have now had 2 headsets not hold a charge. WTH am I doing wrong?

Long version: I purchased this model mostly for the wireless capabilities and for the strap instead of cushion. I have never gotten the headset to hold a charge more than 3 hours. It also has never ever notified me of battery life before completely shutting off. I've literally tried everything I could think of: charging it in multiple USB ports and outlets, taking the battery out, using it with Ghub and without... I exchanged it for another set and got the EXACT same issue. I wish I was kidding.

Before I take it back AGAIN for good, is there something I'm missing? I actually like how comfortable it is, but I just can't use it plugged in. It takes up two USB ports when I do that which is ridiculous.

Incorrect battery percentage value · Issue #1 · Roliga/g930-battery-percentage
March 17, 2018 - The values don't seem to be totally off though, I believe I was getting ~67% from your software when the Logitech software was showing ~27%, which is a ~40% difference, similar to the one from 45 to a very low value.

I have these for 1 year and a half if I remember correctly, never had any problem with them, but recently I have experienced a problem, maybe the battery is low, and in the G HUB appears that it is low, but when I connect my headphones to charge, the percentage goes up to 86, I disconnect them, they stay at 86 for a while, and then return to the real percentage, and it is annoying because I do not know the real charge that the headphones have, I tried to reset and reinstall G HUB but nothing, I hope to get help, thanks!

Logitech G733 Headset Test Review & 12 Months Use? • DanglisReviews.com
Logitech's Lightspeed technology is not only 5x to 10x faster than Bluetooth, but it also boasts a 1ms speed which is faster than even some low-end wired headsets. Yes, you can charge your headset via the USB-C cable while gaming, my son is doing that all the time, because he simply forgets to charge it otherwise. it is supposed to last 20 hrs with RGB and 29 hrs without RGB - i'd say it doesn't its more like 2 whole workdays, the third workday and sometimes on the second, it'll tell you to recharge. No, you cant use the Logitech G733 with a phone, because it does not support 3.5mm jack, nor have a bluetooth function built in.

My Logitech G733 Gaming Headset does not display the correct charging percentage – Logitech Support + Download
Since releasing the G733, we’ve improved our method of battery state estimation, but it requires the battery to be charged to its maximum capacity. If your Logitech G733 Gaming Headset is showing an inaccurate charging percentage, this may be attributed to fluctuations in the battery's charge voltage, which can vary with the battery's age, ambient temperature and other variables.

r/LogitechG on Reddit: G733 headset Battery not showing correct percentage
April 21, 2019 -

Lately I've noticed that when I press the button on the left side to hear the battery percentage, it will always state the same charge level. The headset was beeping to indicate low battery, but the headset stated 70%
Today, I woke up with it fully charged (10am) and now at 6pm it still states that the battery is fully charged.
Is there a fix for this?
