AOLIKES502540 550mAh Battery Replacement for Sena SMH5 FM, SMH5D FM,SPH10H FM Motorcycles Bluetooth Headset, ICP40 25 40P Battery Replacementf for Nextbase 312GW Dash cam

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 Amazon 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.

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...

My battery went doa after 6 years. Installed this, works great. Let’s see the longevity

Fits as described in an Evo 20s, cannot speak for longevity or charge hold time yet, but I will follow up with that information soon.-update-Was excited that this product worked and fit out of the box for my sena evo 20s. But the battery stopped charging after two charge/discharge cycles....very disappointed with this product

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

I can not speak to the battery life just yet, however installation was a breeze#1. I Removed the 3 size 7 Torx screws from the Sena SMH5 unit. "Please Note remove the screws over a bowl in the event you drop one like I did lol"#2. Pull the other battery out carefully from the connection on the board and be mindful of the double sided tape on the battery it is sitting flush to the circuit board.#3. Check the polarity of the wires on the old battery and the new one to make sure that they match#4. Install the new battery if the wires match up back onto the circuit board.#5. I used some 3M double sided tape on the battery back to the housing not the circuit board when I placed it back together.#6. Lastly install the 3 size 7 Torx screws back in there place and then power on your Sena Smh5 unit to see if the lighting comes on as it should.Three other things you may want to take note of#1. If you drop the rubber charging cover " like I did " it does slip back into it's place#2. Make sure you do not over charge your new battery like I did my old one, as I had to do all of this because I overcharged the factory battery lol#3. Small hands and fingers will be helpful my large hands and large digits made it trying placing the battery back onto the board, not to proud to say I called my wife over to help with that part lolBest of luck and hope that this helps someone else

Really an easy review to write.This was a direct replacement for my 5 year old communicators battery.Plugged it in place, charged it fir a few hours and it has worked perfectly.Battery life is better than the oem one.

I replaced the battery in each of my 2 Sena 50s units (with guidance from a helpful YouTube vid). The 20% increase in the mAh rating in these batteries will help with daily longevity. Perfect fit. Units work great & all settings were retained. Happy motorcyclist here. 🤠👍
