STARNOVO 800mAh 3.7V Battery For Sena 20S, 20S-01, 20S EVO Motorcycle Bluetooth Headset, helmet intercom, Battery Model:CP-SN10S

supper fast shipping, ordered last night and received next day.Little bigger size but works perfectly.Highly recommended.

This battery works... although it is slightly larger in side.If you look at the picture I have attached, the right side where it gets close to the rotary dial switch... don't get the battery too close to this.The solution: carefully use an exacto knife to delicately trim the original battery "stays" on the left side of where the battery sits. The 'stays" (black plastic walls) limited the battery from moving any further to the left... trim those away, install the battery slightly to the left, and use tiny pieces of 3M double sided automotive tape to keep it in place.Walla, everything works fine. Like other people stated, not sure if the increased capacity helps battery life a ton, but it should.Next person that reviews this and says "iT dOeSnT fiT!" probably didn't use their critical thinking skills.

This is an exact replacement for the Sena 20 and It's simple to replace and is a higher capacity than the OEM battery. Great quality and price

Worked great for my EVO20s. Plug and play, very easy to change out.

Arrived on time. Works as it's supposed to.

Great replacement for my Sena 20s

I like that it last longer than the original battery. Reliability

It was fairly easy to install. Factory clips meant you just have to open the send up, take em out the old battery and put this one in.

My dual Sena 20S with date code 2018 batteries both started dying after only 45-60 minutes of riding. These were easy replacements.

Sena head set. Installed the road 3500 miles in 12 days and worked perfectly

Bought as a replacement for the stock 650mah Lipo battery found in the Sena 20S. I'm happy to report that this battery fits(barely) into the 20S. It is a very tight fit though with zero room to spare. It's a tad longer and just ever so slightly wider than the original battery. Despite it's slightly larger size it does not interfere with the weather seal of the device. The added length does cause the battery to make contact with the jog dial shaft which adds resistance to it's rotation giving it a stiffer feel. This however does not effect the function of the jog dial. The connector is the correct type and plugs into the unit the same as the factory battery.Time will tell if the extra capacity of this 800mah battery will provide any noticeable difference compared to the original 650mah rated battery. I will update this review with information regarding battery life after I've had time to adequately test it. All in all I am satisfied with the purchase and recommended it to my friend who also owns a Sena 20S with a bad battery.

This battery still running. We hardly use them and now all the newer senas are way better

This battery works perfectly in my Sena 20s. I made the mistake of leaving my Sena on the charger to long too many times so it's battery wore out quicker than it should. Sadly Sena sucks in that they don't provide replacement battery's since they want you to have to pay over $300 to buy a new one as soon as the battery wears out. I'm was thrilled to find this battery at a reasonable price. It's easy to put into a Sena 20S. My only complaint is that this battery is slightly bigger than the original Sena battery so it was a real bugger fitting it in.

My SENA 20S stopped working. The SENA told me that my only option was replace it with a new one.Instead, I bought one of these batteries.I was concerned about the size but, as the seller represented, although a bit bigger it fits fine.After watching an instruction video in YouTube, I replaced the battery and the unit now works fine.Highly recommended.

Works good
