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

I used this battery as a replacement for a faulty Corsair HS70 wireless. Those are now sold as Corsair he wireless pro. I'm quite unsure about the differences between these generations, but one thing is consistent, their awful battery life. The headset would only work for about 6 hours, which is not the time advertised at all (10+ hours). Moreover, the original battery on the headset stopped working after two years with minimal use.I decided to upgrade the battery and got this one. The battery replacement process was slightly tedious since the previous battery was soldered to the main headset chip. The battery is thick, but it still fits. I even used thick double sided tape in order to secure the battery in place.Anyhow, this battery has been working wonderfully for about a week. The headset can easily last about 10 hours or more.I'd definitely recommend this battery. But make sure you have some previous knowledge or watch some YouTube videos before you change the battery.

Battery in my Corsair Virtuoso RGB SE headphones wouldnt take a charge anymore. This fixed the headphones. The price was totally worth it to keep these expensive headphones going. Replaced the 1200 mah stock battery with this 1800 mah battery so this lasts longer on a charge. This battery is thicker than the stock battery so it is a snug fit when screwing the speaker plate back down, so be careful, but the tension holds the battery in place. The plug wiring was correct and I did not have to swap the black and red wires. We will now see how long this battery lasts.

I was initially hesitant because some reviews made it seem like the battery would not fit. However, after taking the headset apart, it fit perfectly fine. The wires come out differently so I had to bend them weird, and while I was worried they would break, it was fine. I did have an issue where the wire was not in the plastic connector all the way, but I easily fixed that and now it isn’t a problem—but it will need checked. Didn’t charge correctly at first but once I left it in for a while, it charged all the way up. Note, the software doesn’t process it the same so it may only charge to low 90s or so, but should last a long time. Probably one of the cheaper options, but works just as well. So, ultimately, while installation isn’t the easiest thing in the world, as long as you’re careful and you get it into the spot, it will work great. Ultimately a good value for your money that is pretty straightforward to get working, though there is questionable quality in terms of the connector (need to check), and it remains to be seen if it continues to work well. We will see.

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.

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.

this add was incorrect or confused , it's not 1800Ma , it 1400Ma . Says right on the battery 1400Ma bought this thinking , great,, made so it should fit no problem . WRONG , I had to gut the inner ear plate that fits over the battery , then had to completely remove the plate , this battery is to fat . I also would not recommend the corsair headphones to start with , after learning that the wires are as thin and a human hair and not long enough to lay the ear piece on it's side while replacing the battery , the wire will probably break and most likely will . After replacing by soldering the lead wires and adding some length to them and using a dab of glue to hold the battery in place , the headphones work great. After this , Best idea I had was I bought a pair of Logitech G533 headphone for the foreseeable future as i do not want to go through this again , the batter is a easy replace on them ,
