AOLIKES3.7v 1400mAh Battery Replacement for Sena 50R, 50R-01 Motorcycle Bluetooth Headset, SP76 Battery Replacement (NOT Compatible with 50R 3-Button)

When my Sena 50R started to go dead after a few minutes use, I knew it needed a new battery. I found the AOLIKES for a great price at Amazon and gave it a try. It took about an hour to get the 50R apart and swap batteries. The AOLIKES appears identical to the original battery and has a 1400 mah rating vs the original with a 900. After a full charge I reset the Sena and started the Bluetooth connection to my iPhone. I also started the fm radio. After three or four hours of use the Sena showed the battery was at 60%. I took several bike rides with similar results. The new battery is better than the original. Very happy customer.

This replacement battery was installed in my motorcycle helmet headset to replace the original. This battery has led to a much longer headset life and replacement was very straightforward.

fixed my few-year-old battery issue on my sena 50r. it works with the 3 button, if your 3 button has the 2 wire battery, mine did.

No clue if it even worked. Took out of the package, removed from the bag & the red wire came off of the battery.

I recently received the 3.7v 1400mAh Battery, and I must say, it's a top-notch power source. After several cycles of use, the battery has proven to be reliable and holds a charge as expected. Its size fits perfectly for my device, and the energy output is consistent. To ensure accuracy, I verified the voltage with a multimeter, and it matched up precisely with the specifications stated, which is reassuring in terms of quality control.
