2PCS NP-45 Battery, Compatible with Steelseries Headset Battery for Arctis Nova Pro Wireless Multi-System Gaming Headset for Xbox, for PlayStation Battery

Works great. Slightly larger that Steel series charger but after a few pushes works great

These batteries had issues. First of all they had a poor fit in the Steel Series charger and constantly popped out. In addition, they were very tight to place in headset. A close examination of the physical battery appeared to be derived from a different battery in terms of construction. When used, they did not hold a charge as long as the original SteelSeries batteries did.

But I wouldn't use them in my headset. They don't fit in the charger at all and while you could press it in to sit well to charge, I don't recommend doing so as you might not get them back out again. They fit in the headset itself tightly already. Don't risk it...the headsets are too expensive to ruin with cheap batteries.

These have a lot more battery life then the ones that come with the headphones and fit perfectly

Cheap batteries from original ma factures failed so got these. They work, not sure how long though.

Right away, both only held ~10 hours charge. Not a huge deal, but now I noticed one battery has swollen and popped out of its housing. Owned for 1 month. The top side of black plastic is releasing, revealing the swelling battery. Obviously won't use that one anymore for safety reasons (and it DEFINITELY wouldn't fit, now) Maybe this is more due to lack of battery over-charging protection on the Steel Series base station (thought it had it, but idk?)... BUT both batteries barely fit the headset/charging station from day 1 (super tight, not "just right" like OEM), so I'm inclined to think it has more to do with the quality (or lack thereof) of the batteries.

I ordered these batteries as spares for my OEM Arctic Nova Pro Wireless batteries.They work almost as well as OEM.They charge up quickly, last a long time during use, and have high durability.Made of the same high quality components and manufacturing processes as most OEM batteries (probably in the same factory), these batteries will keep you gaming for hours on end without interrupting your session.These are high quality and represent a significant value proposition for gamers and audiophiles.

You can see the original Steelseries Arctis Nova Pro Wireless battery on the right in the photo. The HamnaKhu NP-45 batteries I received are on the left. The extra plastic at the top of the batteries received from HamnaKhu are a bit raised and on one is shifted to the right. Because of this, they won't fit into the headset, so they're useless to me. They are definitely not the high quality described in this webpage and can't be considered compatible with Steelseries Arctis Nova Pro Wireless since they won't physically fit in my Steelseries Arctis Nova Pro Wireless headset.
