BCXY MH45908 Battery Replacement for Corsair CA-9011127-NA, CA-9011136-AP, Gaming H2100 Dolby 7.1 Wireless Gaming Headset, H2100 Battery

My headset was several years old an the battery life was less than 30 minutes so I order this to try and fix it. Be aware that the screws on the Void headsets seem to be very difficult for most people to get out, make sure you have the right sized screwdriver that doesn't wiggle at all when in the screw head. Other than that, quite easy to replace and works great.

This battery certainly works better than my original now-ballooning lithium that was in there. As others have stated this is 700 vs 1000, so a little bit less life than the original but if you're looking at batteries this will be an improvement.It fits just fine, it's physically a little bit narrower than the original battery.

All in all, the battery seems to be working fine, the minor drawback is that the original battery was 1000mAh rated battery. This is 700mAh rated. This replaced the battery in my wireless headphones (Corsair) battery size (dimensions) and connector type "IS" Crucial!!!

As others have stated it's a 700mah battery instead of the 1000mah but it works I can't complain so far.My headset is about 2 years old so I bought new ear pads and this new battery it works as new again.

It works great. I've had for about 6 weeks so far, lasts for hours of continual use.. FYI the battery is stored on the opposite side from the charging port...

Easy to install after just watching a youtube video on how to do it.

Didn’t work at all
