DC 3.7v 103450 2100mAh Rechargeable Lithium Polymer Battery for Logitech MX1000 MX-1000 M-RAG97 Wireless Bluetooth Mouse 190247-1000, 190247-B000, L-LB2, NTA2253

Worked so well I had to come back to write a review. I replaced my Logitech Pro X Headset battery, the hours til dead are now double. I admit the connector wasnt the correct one so it will take some basic soldering skills to steal the old connector and replace it on the new battery. Very happy with purchase

I needed replacement batteries for (2) Logitech MX1000 mice. The OEM batteries were in a protective case, while these have a protective wrap. The fit was good within the battery cover, but I did have to add some doubled sided tape. Otherwise the battery could move back and forth within the battery housing. Install was easy enough and the batteries were charged upon arrival. The price was fair enough and both batteries worked. Time will tell how long they last. The OEM batteries were 15+ years old and would only last for a few hours of use.

Installed this in one of our iRV3 brake system components (transmitter). It fit fine, but we had to alter the wiring hook-up to connect. So far, it is working ok. Note: an exact replacement for the original battery was hard to find and this was the closest option.

I tried this for my 3M Connect headphones and it didn't work at all. I don't know if the battery was to blame, or if there is something wrong with the device. Sent this back.

Works just fine, just be sure to use a soldering gun and heat shrink some wrap around the wires. I added some extra electrical tape for security and im fine with it. Battery lasts days without charging as opposed to one day and needed to charge every night. Wonderful!

Used in the Outrush R helmet to replace the failed battery. It is working well so far. I don't have the totall hours between charges yet. I would recommend it at this point though. Quality send pretty decent.

It also functions with a Corsair Void Elite headset after a minor modification to the housing. This change doubles my listening time. I simply swapped the black and yellow lead pins inside the connector, which is straightforward and trimmed where the old battery sat. (There is a slight ridge that needs removed and the top screw standoff gets cut away)

Not for MX Master series, even it's push for the searching.

Used it on my Corsair HS80 a lot thicker than original but removed plastic part to make a lot of space and locked in with screw. Need to swap the two wires . Works

Fácil de montar, y dura su carga

Zocht een vervangende batterij voor een track&trace; kabeltjes doorgeknipt en gesoldeerd voor juiste polariteit. Krimphoesje zat erbij, handig.

DELUXのM618XSDのバッテリーが充電できなくなったのでこちらに置換。 土台パーツが使えなくなりますが容量が倍以上になった事もあり、１日１０時間使用でも２週間で１度の充電で賄えるようになり大変満足しています。 熱収縮チューブも付属してたのでレジン等で保護をしなくてもよく、元の3Pinと接続も容易でした。

Bon produit, se montent bien en lieu et place de la précédente ! Bonne description.
