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

Purchased to replace dead battery in a bluetooth speaker. Works great, holds a charge for a long time and very reliable.

This battery lasts forever, I replaced my headset battery which had completely stop charging with this one and the battery life hasn't ever been better. Takes almost 2-3 days of 8-10 hours of use before needed a good charge. Very happy with this purchase.

I bought this to replace the battery in my Corsair HS70 Pro Headset. I had to move the wires around in the connector but other than that it was pretty easy and fit with no modifications. I don't know about the battery quality. Time will tell.

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!

I bought this to replace a damaged battery in a Creative Sound Blaster E5. It's not exactly the same capacity, but works just fine. So far the battery has worked perfectly, it probably will hold the charge for less time than the original one as it's a bit smaller, but the difference is not as noticeable in my use case where I have the DAC connected to a power source most of the time.

Good battery used to replace battery that died. Was just as described.

This battery rated at more than double the capacity of the Roku Voice Pro remotes battery. It has a larger physical size and a smaller connector. Replaced the connector with the original batteries connector and had to trim some plastic off the inside of the back shell to get a good fit. Now the remote doesn't die after 3 or 4 days.Update: Installed 22 days ago use the remote several times a day with voice input on. So far only used 15% of the battery capacity.

Great battery perfect fit and power
