Sena 20S battery replacement | Masons ADV |

[@ashmoney]

Thank you so much!! I was able to fix my Sena for only $20 and less than 5 min. Easiest fix ever. I’m so grateful for your video..I’m about to ride my Vespa from SF to LA and really needed the second headset. You’re the best 🙏🏻🥲❤️

[@Slygrin1]

Got my battery today. Only took a few minutes to change out. It took longer to gather up the 3 tools it took. Thanks for posting the video.

[@masonsadv]

Glad it helped! Cheers Mike.

[@Slygrin1]

@@masonsadv It's working great. Only thing different from your video, mine used T7 screws. Again, thanks for the video, made it very easy to change out the battery.

[@hotelsierra1]

Thank you! With your help we changed out batteries on dead Senas and now we're back on the road with coms.

[@masonsadv]

Nice! 🙂👍

[@JFizoust]

Thanks for taking the time to make and post this video. I had the tools just lacked the confidence to dive into it. Was helpful, thanks! Ride safe.

[@masonsadv]

Cheers! Great to hear it helped :)

[@greatfallskam]

Thanks for helping us keep those Sena 20S going.....2nd, 3rd, and many more lives.

Your close in camera work is outstanding! So rare to get that clarity without refocusing.

[@migk63]

Thanks Mason, Im from from Australia, you're a legend.

[@drbucker]

Thanks Mason! I followed your advice, got 2 new batteries and installed them easily. Both units powered up right away. I was ready to chuck these things until I found your video, so you are da man! Great video and info, much appreciated.

[@masonsadv]

Glad I could help! Cheers Stephen.

[@BigDeeInnerGee]

Thanks for the vid. The first battery replacement worked well. Then it stopped working. Replaced it again and didnt work. And again, same results. Just discovered there is a SECOND BATTERY under the board. Mine is ballooned and needs replaced. Almost gave up on my 20S until just discovering this. Will post a vid up once its replaced.

[@masonsadv]

Ah, interesting! Thanks for the info 👍

[@roarman75]

Correct. Both batteries need to be replaced.

[@pyro707]

@@roarman75 Didn’t know that the unit has a second battery 🔋.

[@pyro707]

@Nate B1223 got a video or a picture of the second battery under the board?

[@pyro707]

Nothing yet?

[@ImagePhotoMotorsports]

Thanks for posting Mason. I'm in CA and found the exact battery as you did in Canada. FYI the seller is both on Amazon as well as eBay. Readers, just look for the seller or brand name as OALIKES which is common in both retail sites. One point I must mention is the fact since the replacement battery is slightly larger, one might have to, as I did, trim off a LITTLE foil from the 2 corners of the new battery, 2 corners opposite end of the wiring. Just a very little 45 deg cut of the foil in each corner. so the battery can better fit into case. Even then, it rests very close to the dial shaft on the other battery side. When you close the case up, before screwing down, press the cases together firmly so the gasket visually fits in and the upper and lower plastic case meet. Then screw down slowly and securely being sure NOT to over-tighten. Thanks again for your excellent video.

[@masonsadv]

Thanks Steve, some good pointers there. I have heard of the foil needing to be trimmed but mine was fine for some reason. Good to know you made it fit 👍

[@ericcabedoce1505]

i just wanteds to say thanks for sharing this. those unit cost a lot and battery died . Thanks a lot :)

[@Myggan]

Thanks a lot for posting this video, looking into buying a used 20S but was worried about the battery capacity as the old user haven't had it charged in a few years, but now I can buy it knowing that replacing the battery will be a walk in the park.

[@Kronicle]

Thank you for the straight forward video, information AND the links to relevant store pages. Looking forward to replacing my Sena 20s battery after having left it off charge for too long.

[@MotoTrotter]

thank you! with your tutorial i replaced the battery of my 20s and saved a lot of money!

[@yayyy7778]

Thx for posting this! Just ordered the batts for our 2 senas. Mine was DOA a week ago. Was super bummed but have hope now. Whether it works for me or or not I appreciate the video and part number. Keep it right side up!

[@masonsadv]

Awesome, I hope it works for you :)

[@DrifterDon]

Hi Mason: Thanks for the video. Looks simple enough so I ordered a new battery. The recommended 20S one is now a 750mah. It arrives Thursday; I will let you know how it works out.

[@masonsadv]

Awesome! Good luck :)

[@DrifterDon]

@@masonsadv The switch to the 750mah went almost flawlessly. The 750 is slightly smaller and thinner so installation was easy. The amusing part was getting the old 650 battery out. It would not come out. Careful inspection showed it was taped to the circuit board with two-sided tape. Also the jog wheel wouldn't pry up gently, but came off with the shell. I gave the reassembled unit a full charge and everything seems to be working fine.

[@markguilaran]

Thanks for posting this video! You totally helped me not buy a new Sena.

[@Mindtweaker2]

Thank you for posting this, and putting the exact battery we need on your affiliate page. The video was to the point, and made it very easy to install the battery with little issue. My 20S is like new now!

[@masonsadv]

Glad it helped. Cheers Owens!

[@mikethecleav172]

Mine needed a T7 bit. Thanks for the video. I thought I was screwed as well. Installed 850mah battery. Back in buisness

[@58gennaro]

I did have to snip the curved end off where the battery rests against, otherwise, I couldn't get everything to seat properly. I see no problem having done that. Thanks again for the link to the battery.

[@masonsadv]

There ya go! Nice fix :) Cheers

[@Ron_C]

Nicely done! I had an old Cardo Scalia RIder with a failed battery years ago. Some research revealed that a 1st generation iPod batter was a perfect fit. Biggest problem I had was those units were waterproof, so I had to remove a lot of “goop”...still, worth the savings.

[@masonsadv]

Yeah, it would be, Ron. Nice work around :)

[@uwehelbig8244]

Thanks Mason, change the battery in about 20 min. Very helpfull posting.

[@LTVoyager]

I recently replaced the battery in my iPhone 5s. It was a pain with many very, very small screws, but it was successful and my phone now lasts all day again (I was down to about 3 hours of battery charge life). Good to see you can do the same with communicators.

[@masonsadv]

It's a great feeling to easily solve a problem that you thought may cost you hundreds of dollars! Nice save on the iPhone! Cheers 👍

[@tobyray8700]

Thanks for the video. Sold my BMW 5 years ago & put my helmet away. Bought new BMW, 🎊 got helmet out….. Sena was dead 😂.

[@58gennaro]

Did one in the fall. Thanks for the link for the direct replacement. Doing the other now.

[@masonsadv]

Awesome! Glad to help ;) Sure beats replacing the unit! Cheers :)

[@fontanajim]

Perfect! Thanks for posting.

[@pinkiewerewolf]

Nicely done Mason. I still haven't pulled the plug on a comm unit. They would be handy for music but I ride alone most of the time.

[@frostbitevinnie]

I ride alone as well but a com unit is great for music, phone calls, etc...

[@masonsadv]

I was skeptical at first too. They are not inexpensive and I had ridden for so many years without them that I really didn't want to interrupt the peace and quiet of the ride. Now, I couldn't be without one. The safety factor when riding with a group is priceless and my family knows they can reach me if necessary. Occasionally on a longer ride I will use it for music but more often than not I still ride in silence ;)

[@Melon-gb5vd]

Hey pinkie I ride alone most of the time so I have 911 on one of my speed dials. As long as I am conscious I can still contact emergency services without having to pick up the phone.

[@pinkiewerewolf]

@@Melon-gb5vd That's an. Excellent idea Melon. You might've just turned the tide in favor of getting a comm system.

[@denisehoefs6553]

Thank you for the video. Found my battery on Amazon. Easy to change out. Thank you again.

[@masonsadv]

Glad to help! Cheers.

[@cinemawerks]

Exactly the video help I needed to do my battery replacement. (Mine turned out to be a T6 instead of T8, but otherwise identical replacement.) THANKS!

[@masonsadv]

Awesome! Glad to help :)

[@speedn16v]

I couldn't find any videos specific for my 10s, but the construction is very similar. Phillips screws, instead of the Torx, and you can just separate the case halves, and the wheel will slide off, staying with the other half of the case. I wish I did this sooner, I'm only getting a couple hours out of a full charge.

[@masonsadv]

Awesome! I hope it works out for you :)

[@happytrails1963]

2nd time for me to have to replace 20s Evo battery, if in the US you can buy them off ebay fairly cheap $18 plugs and play, good luck!!

[@jameswalkerbassandkeyboard7644]

Great video. Worked like a charm!

[@WesMantoothPDX]

I have two Sena 20s units. One just went out with no charging abillity. I am finding the battery i think will work in PDX and will let you know what works, etc.Thank you for posting!

[@alexbell1232]

This worked perfectly and was easy to do. Why won't Sena tell their customers this? I can only surmise that they want to sell you another new unit or in my case they offered a discount on the inferior 30K when I wanted the 50S. Also due to pandemic they won't ship to Canada. So I can't even take advantage of their offer. I know these are difficult times but surely Sena can do better for their loyal customers.

[@200xcBruce]

Very good thanks I added to my Amazon wish list in the event mine after 3 yrs takes a dive into death. $17.99 is much better than a new unit.

[@masonsadv]

Sure is! 👍 Cheers Bruce :)

[@312cycles]

Sena 20s Works without a battery and not being plugged in. Battery status says full when I check. How is that for you? We were having problems with one of our units. It shut down and couldn't get it to turn back on. Series of blinking lights is all we could get. Tried to update it but after the update it said update again. So it wasn't accepting the update. Saw your video, thank you very much for your work. Ordered a battery tried to replace it same issue. For whatever reason I thought maybe I would take out the battery and try to turn it on to relieve it of any electrical charge that maybe still in there. And somehow get it to reset. To my surprise, and amazement, it is working and has been working for about 30 minutes now. Paired up, playing music... WORKING WITHOUT A BATTERY! ???????? Currently afraid to turn it off and try to update it and put the battery back in. I really don't know what to do...

[@masonsadv]

They will run on the charge cable even without a battery but I'm sure the new battery will solve the issue if it will run on the cord. Good luck!

[@312cycles]

@@masonsadv sorry. It will work without a battery and without plugged in. I have to repeat that, It will run without a battery and without being plugged in. I have video. I let it run playing FM radio for like 2 hours before I finally shut it off. Again not plugged in and without battery.

[@CanyoneerDuke]

Nice job and very helpful. Thank you

[@masonsadv]

I am sitting here at my desk and just replaced my battery. Easy enough to do, even though messing with the screws would have probably been easier 20 years go. thanks for the video.

[@masonsadv]

Mhmm, Enter the reading glasses!! 😄 Glad it helped. Cheers Larry.

[@jvman4971]

Thank you for the info!!! My Sena just died today and thought I be spending hundreds for a new one. Do you have a direct link for the battery? When I follow your link it takes me to your Amazon page, but I can't find the battery. I have however found other great things !

[@rajudeoxingrdx349]

What’s the battery life of Sena 20 S?

[@gregglazzara3679]

I replaced the battery in my Sena 20s. The volume for music and voice prompts is so low I can barely hear it. Any help would be appreciated.

[@ianferrier235]

Thanks Mason, good to know we all run sena in our house. I wonder if the smh 10 uses the same back.

[@masonsadv]

Hmm, not sure Ian. Good Question. Maybe someone here can chime in? Cheers!

[@wishedsolid219]

Would you have any idea where on the circuit board the ambient microphone is? Also, great vid, will surely be helpful when i would have to change mine.

[@masonsadv]

I didn't actually look for that when I was in there so no, sorry.

[@jozeffarkas9111]

Hi there :) Mason, do you know that Sena 20S has two batteries inside? One is 650mAh, second smaller 100mAh. I dont know for what is the second battery there. Do you know?

[@masonsadv]

No I don't. If that's true then the small one is likely just to hold the memory when the device is dead but this is the first I've heard of it.

[@jimmy300x]

Correct Jozef, the bigger one is a 3.7v 650mah and the smaller one located between the base housing and the electrical board is 3.7v 100mah. I just replaced both batteries in my 20s and my wifes.

[@michaelkvietkus]

@@jimmy300x I just ordered a replacement for the 2nd little battery. Size for others is as Jimmy states, dimensions are 401822 which is 4.0 mm by 18mm by 22mm. @Jimmy300x could you comment about how you dealt with the comb pin connector alignment? As I'm waiting for my batteries to arrive, I have not been able to determine the best procedure for reseating the board plus pin alignment without breaking a pin off. Big thanks, if you could comment please.

[@jimmy300x]

@@michaelkvietkus from memory I took the wheel off, took the front cover off, removed one battery and carefully removed the circuit board giving you access to the second battery. Be gentle and you won't bend or break pins. Make sure you pay attention to the rubber seal when closing the unit up.

[@0873sp]

Hello. Were you using an ESD strap on your wrist while doing this? It would suck if you fried a circuit by a static discharge.

[@masonsadv]

Yes, that would suck but it's not something I own. The best I can do is touch off somewhere before starting the job. The Sena didn't concern me but I did think about it when I was building up the new editing rig a couple weeks ago. It was a bit more valuable! 😄👍 Cheers!

[@Melon-gb5vd]

Both Mason and I can attest to the water resistance of these as we both have ridden in mega downpours and no issues. As you can circuit his circuit board is clean no corrosion. As for that battery it is currently unavailable from the .ca site.

[@masonsadv]

Thanks for the heads up Melon. I'll look into that

[@Melon-gb5vd]

Masons ADV Ebay does have them shipped out of the states good for the stateside people

[@DaveDayve]

What's wrong with people. When the tail is at the top, they want the plate n indicators somewhere else and vice versa. They've cleaned up the top rear end. It's lovely. Want to fill it up? Get a differentmodel. That's people for u hey Davey boy ☺ . Great video close ups n all luv it. ☺

[@vector011]

Where is battery link???

[@jeffirwin485]

Maybe I missed this somewhere along the way - but you have a note in your store that this battery won't work on an EVO. Do you have a link for the evo battery?

[@masonsadv]

Hmm, no I don't Jeff. I would suggest if it's dead anyway, open it up and see whats in there. It may be a similar cell with a different plug you can solder on? Good luck!

[@kelbyray]

Helped me out. Thanks!

[@masonsadv]

[@ac4037]

I used your video to change the batteries on a pair of evo's and after charging, they powered on and synced together, but no audio. Not even the hello or goodbye. Does anyone know what may have caused that issue? I'm starting to think Sena put a trigger in the circuit to kill it if a battery swap was done.

[@masonsadv]

I haven't heard of that before but anything is possible. I would start by checking the volume hasn't been set to zero with the reset and then check and clean the speaker connection but if both have done the same thing it's unlikely to be that. Keep me posted

[@donmachuca2433]

Hi! Would you know the actual dimensions of the replacement battery? The one I'm looking at is 34x62x5mm.

[@masonsadv]

I'm sorry Don but I don't.

[@craigbazan9072]

Hello Mason. My names Craig and I’m from Vancouver Canada. Really enjoy your videos! Quick question about your rox risers. I’m 6’9” and am trying to get a bit more comfortable of my 2018 KLR. I purchased some new footpeg mounts that lower the pegs 1.5” but would also like to get some risers. I noticed rox makes upto a 3.5” riser. Wondering if I could get your opinion about how that would fit the bike and if I’d have to get new cables. Know you’re not a pro or anything but value your opinion. Thx a lot.

[@masonsadv]

Hi Craig, I think that would make a big difference for you for sure! With the 2" rox risers the OEM cables are fine but need rerouting. The 3.5 will almost defiantly require longer cables but I think it would be worth it for you. It makes such a huge difference. Good luck! Cheers:)

[@craigbazan9072]

Masons ADV thanks so much mason. Any idea where a guy could get extended cable. Having a tough time finding some!

[@masonsadv]

The part # I'm finding is, Motion Pro +3.5" Longer Clutch Cable For Kawasaki KLR 650 08-15 03-0441. Motion pro shows 2 cables and this should be the longer one but I haven't tried it myself so it's a guess.

[@denouden92]
