STARNOVO 400mAh 3.7V Replacement Battery for Logitech H800 H820e Wireless Headset, 533-000095

This sort of battery is nothing special now. Many of the options available sacrifice function for form, like the original. This battery is nothing that it doesn't need to be, just the battery and the necessary cable, no unnecessary plastic casing. Removing the old one is simple, just release the left cover and then fish the battery out. The connector is clipped in, you can just pop it out by lifting up the front. The new connector is very tight, but you just need to cram it together... but make sure it is aligned the way the original one was. Check the image attached. Typically the old battery didn't last through my normal use in one working day. I haven't tried to time the continuous use life, but I am coming to the end of my second working day and the new one is still going. So far I have no regrets, this and the replacement ear cushions have returned my old H800s to better than new state.

I'm pretty happy with this upgraded battery for my Logitech H800.My USB port is broken (on 2 headsets). So I have built a charging station w/ a Micro USB PCB and use small leads into the battery's socket to charge it.Sure, I could get (or do myself) a repair on the headsets USB port...but the USB port would prolly go bad again. With this battery I get almost 2 days use per charge (as this battery is 400 mAh - the original is 260 mAh, I think). So swapping the battery isn't such a big deal. Buying a second one right after this review.I did not have a problem with the larger capacity fitting into the H800 slot. W/out the plastic case it ends up being a teeny bit smaller than the original. The 1st time that I plugged it in, it was very tight and I had to use a pair of need nose pliers to get it snapped in. Haven't had that problem since. Also tried another H800 replacement (w/ a 320 mAh) it was fine, but doesn't last as long and actually (w/ it wiring) fits more awkwardly.Whether you have broken the USB port (YET!) or not I'd recommend doing this upgrade for your H800!!

It's working great!

I replaced the original 265 mAh battery with this 400 mAh battery, and I'm very, very happy. After a full charge last night, I used my Logitech H800 headphones all day in Bluetooth mode listening to music or with the USB Nano mode for Zoom and Teams conference calls... and the battery is still going strong after 12 hours. I'm so happy and appreciative!

This was cheap and has worked great so far in my old Logitech headset I keep in my backpack for quick hands free calls while in working in the field.

This is a review of "STARTONG 400mAh 3.7V Replacement Battery for Logitech H800 H820e Wireless Headset, 533-0". This is a great battery which takes up less space inside of the compartment than the original one. It lasts much longer than the stock battery. It is also heavier than the stock battery.

Works and fits perfect. Got our wireless mic working just great.

Got it just in time...was down to an hour between charges.

Works perfectly on my old Logitech H800 headset and holds the charge for the entire day.

This was a great replacement for my 3 year old H800 headset. It is physically smaller than the original so it does not fit quite as well, but i'm very happy with the longer battery life.

Fantastic product! A cheap way to extend the life of the headset. Installed without any tools at all! You have to be gentle with the connector so you don't damage it and the battery is a tight fit but good to go after that. I've had this for a couple of weeks now and it is great!

Replaced a 7 year old Logitech H800 headset battery that would barely make it through a 1-hour bluetooth phone call. So far, I can get through an entire 8 hour day without charging. No issues with installation. Great to have the extra capacity over the OEM battery. Curious to see how it holds up over the long term.

On a full charge, my Logitech H800 lasts all day again!. The battery fits in the compartment perfectly and works as expected.

Battery fits great, and no installation/connection problems. Looking fwd to a few more years of service out these headphones.

Refurbed my H800 with new (longer lasting) battery and ear pads (separate purchase) and although it was a bit tedious to install (not the replacement battery's fault) It fit and now I can go 8 hours + without charging.

What I read about the batteries advertised for the H600 was that the connector didn't fit.Based on the pictures of this battery, I ordered it for my H600.The connector fit like it was supposed to.The battery was a little larger than the original, but with 10 seconds of trimming the battery compartment it fit and works like a charm.

I've only had the battery for a few days, but it seems like a good investment so far. The original battery was only lasting about 3-4 hours, however this one is lasting the whole work day (~7 hours of use). The LED is red by the end of the day, but I haven't gotten the beep indicating that the battery is on its very last legs.Installing the battery was pretty easy, and the battery is a little bit smaller than the original, so it had no problems fitting inside the headset.

I bought this battery to replace the one in a set of logitech h800 wireless headphones, even though it is advertised as a phone battery. It's a bit smaller than the original, but that's not a problem. Once charged, this battery lasts several hours longer than the original battery. The battery plugged right in, and I haven't had any problems with it.

My Logitech H800 headset started holding a few hours charge at a time. It's been such an awesome headset and really didn't want to buy another headset. It's been the best headset. This battery size is much larger than the stock battery. Install is a breeze. After 3 months I'm still averaging 10-12 hrs. of use. Definitely worth upgrading or replacing to bring our favorite Logitech H800 headset back to life.
