Review: Works perfectly! - I purchased this battery to replace the battery in my Sena 20S BT headset, which I have been using at least weekly since 2017. Last week while riding, I noticed that it was not holding a charge for more than a few hours, even though it had been charging overnight. I took it apart and discovered that the battery was “swollen” and needed to be replaced. I ordered this battery on desertcart after verifying the model number, etc. The battery dimensions and connector are identical to the SENA OEM one. It fit perfectly into the tray and the battery itself appears to be of similar quality as the OEM unit, at least from a visual inspection. I have not personally confirmed its advertised amperage. I plugged it in to verify that it was charging normally for about 20 minutes, before reassembling the headset. I found no indication of delamination, swelling, or felt any heat buildup whatsoever on the battery surface. So far, so good. If anything changes after a few weeks of use, I will update this review. Good luck.
Review: Excellent! - I was a little hesitant, not buying OEM, but it was in stock and the reviews were good, for the 950 mAh model, so I ordered it. Install was easy, peasy, had it installed in about 3 minutes and charged it right up. Worked perfectly and lasts longer than the battery that was in my Sena 20 from new. I'm very pleased with the battery, I was a little hesitant buying the larger size, but I first purchased the smaller capacity one that was supposed to be for my unit and it was dying after about 4 hours or riding. Sent it back after the first ride and ordered this one, fit and worked perfectly and it lasts all day riding and then some. Great choice, easy to install (have to break a little plastic piece off inside the head set to install it or any of them, but that was easy), works perfectly! Will buy again, when this one goes down, probably in 3 years...

### ⭐⭐⭐⭐ Compatible with SENA 20S
*by V***7 on July 14, 2020*

This was a little bigger than the OEM battery, but it fits (barely). Holds a charge and works well. Would buy again for Sena 20S
