802540 3.7v 900mAh Lithium Battery for Sena 10S 20s 30K Series 10S-01 20s-01 20s evo 30K-01D Motorcycles Bluetooth Headset Battery Replacement Intercom

My replacement Sena 20s EVO battery arrived today and I enjoyed 100% success installing it. The 20s evo install instructions are "scary" but very doable. I used youtube video /watch?v=x311Sux8Ppo The sena 20s evo was NOT designed to have its battery replaced. But just because it wasn't designed to be replaced doesn't mean it can't be done. Install instructions such as the above make it possible. YES this battery is about 1/32" wider and 1/16" longer than OEM. HOWEVER it still "fits" without any heroic efforts. I varied from video in two places. a) I used a loop of duct tape to affix the battery to its case vs using the OEM 2-sided tape. I did this because a loop of tape is way thinner makes up for any extra thickness batter might have. b) I used a piece of scotch tape to pin the cable to the battery side as to keep it out of the way during top circuit board insertion. when I was done my unit turn on all the functions worked. I have only owned this unit for a few hours but I know it accepts a full charge and all the evo functions work. Time will tell how long the battery will last. My old battery was 4 yrs old and didn't last long anymore. The picture with a yellow-sided battery is OEM, the picture with the silver battery is its replacement.

Fits and works great in a Sena 20S. In an email Sena claimed that replacing the battery is unserviceable. Suggested I buy a new model. The battery replacement was easy.

Unfortunately, this review will not be about the battery life, but more about the ease of installation. I am not in a position to actually use these yet, but I had my Sena SMH10's main units with me and knew the batteries needed to be changed. My main concerns were fit of the battery and ease of opening up the headset to install the new battery. These batteries came promptly and are a larger capacity battery than the originals in the headsets. After taking out the three screws holding the headset together, I carefully pried the two pieces apart. This took under a minute to do.....from that point on, changing out the battery was simple. It plugs right in to the port that the old battery is unplugged from and fits perfectly into it's alloyed space. Within minutes, the two pieces were fit back together and screwed right. I immediately charged both units and, initially amber, they were soon blue, indictating a charge. I know they will now work, but don't have the helmets or mic attachments with me to actually use them as this equipment is in another state. At least I'll be ready to go when I finally hop onto my scooters in a few months!

Seems to have done the trick. One ride under my belt with the new battery and it didn't die 3/4 of the way thru like the old one.

Installation was easy, however this was my second battery from them. The first one I got, plugged it it and it started to get hot a d caught fire, so I got a replacement, this one installed fine again, my sena 20s turned on just fine. But even after fully charging it didn't even last a trip to work and back. It's about a 20 minute trip one way, I turn it off at work, then my sena dies on me before I can even make it home. Not sure if I just got 2 bad batteries, but this has been my experience with the 2 I got.

Battery lasted with continuous mesh and music for about 5 hours,I did turn it off during rest stops from Jersey to Tennessee but was slightly let down. Friend has a newer version of 30k but his lasted about 2 hours longer I'm surprised when comparing the mAh one would think it would be comparable or surpass the discharge rate. It fits, it's functional but know it will come up a little short

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,

Battery burned out after first use

Fake product never gets delivered. I placed the order twice. Both the times it got cancelled after over 15days.

Gostei da capacidade das baterias, substituição de baterias antigas que perderam capacidade de carga

Se monte parfaitement dans mon Cardo freecom 2+ il faut juste coupé la prise et souder les deux files à la place des anciens

Ottimo prodotto

Fitted my radio perfectly...thanks!!
