KARUF 3.7v 1800mAh Battery Replacement for Corsair HS70,HS75 XB, Void Pro RGB Headset, HyperX Cloud III/Cloud II Headset

Needed to replace the stock battery in a Corsair HS70 Pro Wireless that was getting less than 2hrs on a full charge.Highly recommend watching YouTube videos on how to replace this before purchasing. Although the headset's battery is replaceable, the process is not user friendly.The stock battery is glued into place so you'll need something to break the adhesive and pry it out. Two wires had to be reversed as shown in the product photos. There are no included instructions so be sure to check the wires before installing. I used a utility knife to pry up the clips holding the wires in the connector.DO NOT let the wires touch. Wrap the connectors in electrical tape while reversing them.The angle of the female connector made this very difficult to reinstall so I had to bend it slightly to get it to fully insert.A bit of super glue got this to hold in place.Left the headset on for 8 hours straight and it wasn't beeping that the battery was low.Very happy getting another few years out of this headset at a fraction of the cost of tossing it for a new one. Great battery that works as advertised.

I purchased this to replace the battery in my wireless CORSAIR gaming headphones which was not holding a charge anymore. After following directions I found on YouTube for this known issue, this battery is working like a champ and holding a charge. Very pleased that I could keep the headphones and just replace the battery to get more use out of them.

Corsair apparently uses cheap cells in their gear, which is a shame but I guess that's how they keep the price down. You access the battery by removing the cover on the right ear cup (the one without power and volume and mute buttons). You will need computer screw drivers and possibly something to help you turn the screw driver (rubber jar opener) because they are tight. Gently lift the speaker off the earcup because there are wires attached to it. Then you need to access three more screws on the black plastic shield that holds the battery in place they are just as annoying to remove as the ones on the outside. The battery has a plug just pull it out but pay attention to where the red wire is located while it's plugged in. I didn't have a problem with an incorrectly wired plug but I guess it's happened so be sure red or + is on the top of the connector not the bottom. The new battery has it on top you can change it if you need to but hopefully you won't have to. Use small pliers or tweezers to plug in the battery which should only plug in one way red wire on top. Be aware this is not an "exact" replacement the battery holder assumes the wires come off the center of the battery but this new battery it comes off a side so you'll have to make a new slot in the battery holder for the wire to come out or just break the little plastic piece off on one side of the center hole. The old battery is taped into the battery holder, rather than put double sided tape on there that will have to be removed again I just put some scotch tape on it once the cover is screwed down there's no need to have glue inside the battery cover. It isn't a particularly tight fit don't worry, just screw down the battery cover a few turns then put the speaker back in and that will hold everything in place. If the wires won't reach the battery connector you may have to CAREFULLY cut the plastic wrapper on the battery so the wires can move more towards the center...be careful if you cut the wires you've destroyed it. I just put a couple screws back in and plugged it in to be sure it was going to charge. if it all works put the rest of the screws in and the ear cup back on and away you go. Twenty dollars for a battery was kinda nuts but I suppose it's better than 90 for a new headset. Be aware these batteries come in two wire and three wire, the videos all agree you need the three because that extra wire is part of the charging circuit. You can get these a bit cheaper if you're willing to mess with putting your own connector on the end of the wires coming from the battery (or even steal the old one off the dead battery and put it on the new one) but I'm getting too old for lilliputian connectors on stuff like this, let somebody else do that if they want to. While all the videos I watched said you can put whatever battery fits in this headset it's unknown if you'll actually get the full charge if the charging circuit in the headset doesn't understand there's a bigger battery now. No matter if you're getting full charge it's still better than a hundred bucks to replace your headset. I have two of these the other one probably will need a battery soon as well I just I can't complain as i've had them a few years and batteries just quit after a lot of use that's normal.

I can't comment on longevity of this battery, as I just purchased it a few days ago. I bought it to replace the factory battery in my Corsair HS70 Pro Wireless headset and it was a perfect fit. The only thing that might be a pain for some folks to install, is that the positive and negative wiring was reversed with the new battery. It took me five minutes with a letter opener and my magnifying glass light to gently pry the plastic tangs holding the positive and negative wires in the tiny connector of the new battery to swap the position of the two wires. I used some electrical tape to fold and attach the battery to the housing in the headphone case. After getting the headphones back together, I tested turning them on and they powered on fine. I let them charge fully, then used them for hours the next day unplugged. So far, very satisfied with new battery, will see how long it holds up to daily use. Nice to pay $20 to fix versus paying another $100 for a new headset!

As with many of the other reviews, I also had to switch the wires to match the correct polarity with my Corsair HS70 Pro. The replacement took about 20 min altogether with most of it fiddling with the wires prior to the actual replacement. The ear cup comes off fine, remove some screws, and then pry up the old battery from the glue/adhesive that was used. Then simply plug in the new one.The new one worked great for about 3 months with about 6-8 hours of charge (I use my headset all day for work). The next 3 months the charge dropped to around 4hrs and I was getting some spotty charging results. Over the last month, it would spontaneously stop charging and I would get to my desk in the morning and it would only last about 15 minutes. Sometimes it would be dead as a doornail. Then sporadically I would get 3-6 hours of charge out of it again. It has gotten so inconsistent that I'll be buying another battery (possibly from another vendor). Still, it is cheaper than replacing the headset altogether.

if i could give a 0 i would first battery showed up with the negative wire not even attached 2nd one i got after RMA dosent even work polarity is correct biggest scam ive seen on Amazon headset is corsair virtuoso RGB
