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

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

Replaced old battery for Bluetooth headphones. Brand new fully charged it lasted a third less than the original. 6 months later it only lasts about an hour after charging overnight. I bought cheap and it was a mistake.

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

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.

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.

This is one of the least-long-lasting replacement batteries I've used for the H800. After two months it doesn't hold a charge at all.

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.

Works but ran into issues with tubing. Contacted seller for additional tubing but no response
