3.7V 503040 Battery 620mAh for cozmo Vector robot Battery replacement,SkyBell HD WiFi Video Doorbell Flysight FPV wireless speaker battery replacement

Used to replace my Sony XM4’s original battery that suddenly stopped working. Did exactly what I hoped and revived my favourite headphones.

Great value and price, these battery was in the correct polarisation and fitted my needs

I was suffering with bad battery life, the new one lasts for ages and was pretty easy to install, charging and everything seems to work without issue, and no need for any calibration steps, make sure you remount the temperature sensor properly though!

Cannot comment on durability and efficiency of battery as it did not fit device. The size of the battery is as stated, but the connection is slightly different and did not fit my device . If you have the technical ability to cut the wire of your your old battery and replace it on the New battery it might work. However, I’m sure that any guarantees will be not valid .

The battery doesn’t power my headphones after being charged for hours. Very disappointing and will be returning.

Seems to be a good quality replacement for the original: battery life on headphones lasts much longer as a result.

As described used to replace battery in a faulty corsair headset… only negative was battery comes with a connector and i had to solder to the board on the headset but no big deal… battery life much improved

Exact replacement and perfect working order

Una batería pequeña apta para los robots de Anki Cozmo y Vector. En mi caso fue para un Cozmo al que la batería que venía de fábrica no aguantaba ya la carga y era necesario reemplazarla. La batería viene con un conector JST típico en baterías y un pequeño trozo de tubo termorretráctil (que no utilicé). Buena calidad y mayor capacidad que la batería que venía de fábrica con Cozmo. Eso sí, si os aventuráis a desmontar a Cozmo, tened en cuenta que, aunque es relativamente sencillo, hay que hacerlo con cuidado, y la batería tiene que ser soldada a la placa. En cualquier caso, la batería de momento cumple bastante bien y aún no he tenido que cargarla desde que se la coloqué al robot.

Habe diesen Akku in meinen GPS Tracker eingebaut, ausgetauscht gegen den alten kaputten. Hat gut funktioniert mit den Drähten mit Schrumpfhülle. Alles ok. Jetzt funktioniert der Tracker wieder.

Buen producto, rapidez en recibir.Usado para un aplique solar exterior.

Used this battery for my PXC 550 II Did need to swap the wires but it works well.

Parfait. Fonctionne et conforme
