602248 3.7v Battery 700mAh for Sena SMH10 SMH10R SMH10D SMH10-11 SR10 Bluetooth Headset Battery Replacement fits Motorcycles Bluetooth Headset

Worked really well. The plug was identical no need to change like some videos Ive seen.I’m now able to go for long ride without recharging. I get typical 8 to 12 hrs depending on if i play music the entire time . Old battery went about 3 hrs. The new battery is awesome,

Perfect fit in Sena 20S - has the correct connector.

Perfect fit for Sena 30K

I got 2 charges on this battery then it stopped charging.

UPDATE UPDATE UPDATE.............I have a Sena SMH 10 FM. Sena must have a dozen variations of the SMH10. My SMH 10 FM is maybe 7 or 8 years old, but recently, it would shut down after 2 or 3 hours of operation because of “low battery”. This replacement battery looked like an excellent choice due to a one to one replacement. However, upon receipt, the plugs did not match. The replacement battery plug was different, slightly smaller.So I looked at Utube videos on how to solder a new battery to the original plug. Looked like a piece of cake. Except that I had no soldering experience, plus no soldering iron, wire stripper, flux, heat shrink tubing, or solder. I invested in all this electronic equipment that I will probably never use again and, I quickly found out that soldering is a learned skill, and not as easy as the videos portrayed for a first timer.With much frustration, I bungled my way through the soldering the replacement battery to the original equipment plug. I then discovered that the replacement battery was thicker than the original battery!!!! I learned some new curse words in trying to reassemble the unit after I installed the new battery. SON OF A BITCH!!!!!. The two parts did not want to snap together due to a thicker battery!!!! After a half hour or so, and a Herculean struggle, I got the two parts back together.So, 5 stars for having a new battery for a longer operating life, (I hope), and 1 star for the convenience of replacement. YMMV.NEWS FLASH!! It turns out, my Sena unit is a SPH10H, and not a SMH10S.It sure looks like a 10S. but it isn't. I would have thought Sena would standardize the batteries and plugs for the entire 10 line, but not so. so I'm changing my rating to a 5, cause I didn't read the description close enough, and now have it finally installed, all is well,

I have the SMH10-11 dual version and these batteries were a direct replacement. I did verify polarity and it was correct. We’ve had these for 9 years and hopefully for another 9 years now.

Exact fit for my application

This battery is a drop in replacement for the original battery which came on the Sena 20SBonus is that it is 900mah vs the 650 mah OEM battery.
